ERW Process Flowchart



We utilizes a series of quality-controlled checkpoints and inspections that ensure an end product that meets specificationsand exceeds your expectations. It all begins with the best in raw material.

SECTION 1 – RAWMATERIAL PROCUREMENTQuality control is embedded into all steps of our production process, beginning with the purchase of raw material.We use only high-quality, continuous-cast, fully killed, control-rolled, fine-grain, low-carbon steel. This coil issupplied by a number of reliable, reputable suppliers like Bao Steel,Wuhan Steel,Anshan Steel,POSCO,NKKwhich for many years. Coil inventory is stored in a computer database and each coil is marked and checked basedon database identification.

SECTION 2 –STRIP PREPARATIONThe strip preparation section is designed for the shortest possible coil joining times, constant strip tension andprecise strip alignment and thus ensures the stable operation of the tube welding line. In the cross-welder, theends of the coils are cropped, precisely aligned and welded together. Simultaneously, a hole is punched in thecenter of the strip indicating the cross-weld position to be detected later at the front of the tube mill.

SECTION 3 – STRIP ACCUMULATINGThe system is to store the coils in “ externally in and internally out, top in and bottom out” form, to ensurecontinuous feeding and production. A continuous production process is ensured by the use of the horizontal spiralstrip accumulator which bridges the standstill time in the strip preparation section during the welding of the coilends.

SECTION 4 – Patented FORMING.using the latest patented forming system. This system is characterized with auto setting, manual setting and quickroll change to allow for an accurate shaping. This substantially improves the effectiveness and strength of theweld.REFORMING section.This section is designed in such a way that the least possible number of rolls have to be changed during sizechanges. The edge bending section serves to preset the strip edges for proper presentation to the welder. All rollmovements are controlled by the computerized quicksetting system. In front of this section the hole punchedduring the coil joining process at the cross-welder is detected and this information is tracked and transmitted tothe cut-off where the cross-weld is removed.

Straightedge Forming sectionIn the straightedge forming section, the preformed strip is homogeneously shaped into a round cross-section. Thisis performed by two roller beams arranged in pairs in two sections behind one another. Again all roll and beammovements are controlled by the computerized quicksetting system.

Quick-Change SystemExtemely short changing times are achieved using a combination of the "in-line" and "off-line" systems. The"in-line" system consists of the rolls, roll chocks and the change car. The chocks with the "old" rolls are pushedout of the stationary mill stands onto the vacant positions of the change car by use of hydraulic cylinders. Thechange car is then indexed over one position and the "off-line" prepared chocks with the "new" rolls are thenpulled into the stands. The "new" rolls are moved to the work position and set according to stored values in thecomputerized quicksetting system. All operations are fully automatic.The change car is then moved to the "off-line" roll changing area. The "off-line" system consists of a variety ofchanging and roll manipulation devices for removing the "old" rolls from the chocks and replacing them with the"new" rolls in preparation for the next roll change. All the "off-line" work takes place while the mill is running.Mill Changeover SystemsImprove Productivity and Reduce Manufacturing Costs with Patented SystemsIt is important for tube and pipe manufacturers to analyze their changeover requirements carefully. Many factorsdetermine which changeover system best fits production needs. Some of the these factors are:



a. Product Mixb. Run Sizec. Frequency of Runsd. Finished Product Inventorye. Operator Motivational Levelf. Crane Availabilityg. Space Requirementsh. MaintenanceSeven Levels of Changeover Allow for Planned UpgradingLevel #1,#2,&#3: On Line Changeover Reduces Down Time Between Runs.Level#1: Front stand and rolls are removed with the use of cranes. Roll Manipulators aid changing of tooling.Level#2: Powered front stand removal, roll manipulators and roll racks speed up tooling change.Level#3: Continuous Cart Transfer System(CCT)is added on line to facilitate roll change without using cranes.Level#4 & #5: Sub-Plated On Line Changeover is Combined with Off Line change Equipment to Reduce MillDown TimeLevel#4: Includes interchangeable stand assemblies with powered disconnect and crane removal on line, poweredfront stand removal off line, roll manipulators and crane lifted roll racks off line.Level #5: Roll changing off line uses CCT System instead of crane for interchanging roll racks and storing frontstands.Level #6 & #7: Advanced Changeover Systems: No Cranes Required for Minimum Mill Down TimeLevel#6: Automated Transfer Cart (ATC) removes and replaces interchangeable stand assemblies. This Level alsoincludes powdered front stand removal off line, roll manupulators and crane lifted roll racks off line.Level#7: Roll changing off line uses CCT System instead of crane for interchanging roll racks and storing frontstands.

TBS® is an Important Part of Changeover Systems for Tube and Pipe Mills:Abbey Etna’s patented TBS® Forming System has been developed for all mills to reduce roll tooling costs in theforming section, to reduce changeover time, and to improve forming mechanics. This system incorporates manyunique features such as:a. Automatic Setup On-Lineb. Expanded Diameter Rangec. Increased Range of Diameter to Thickness Ratio(D/T)d. Rectilinear/Rotational Adjustment of Beame. Simplified Top Roll Changing

Fin-pass standsThe fin-pass stands are constructed as a 4-roll design. All are equipped with rapid roll changing thanks tohorizontal pushing out and in of the whole roll chock assembly. All roll and assembly movements are controlledby the computerized quicksetting system and roll locations are displayed on the operators screens.

SECTION 5 – HF WELDINGThis 1200 kw/600kw High Frequency Induction/contact solid-state Welder is manufactured by Thermatool Corp,a famous welder manufacturer in the world. It can examine and adjust weld parameters, including temperatureand inside diameter and outside diameter trim removal through computerized processor. It serves to heat the twostrip edges to a molten state prior to entering the squeeze stand.The 5-roll squeeze stand, supplied by Bronx International, is also equipped with a computerized quicksettingsystem ensuring high precision positioning of the weld rolls for proper alignment of the strip edges during thewelding process. The outside scarfer is equipped with two scarfing tools which can be adjusted independently.The patented inside scarfer is equipped with a bead chopper to produce short chips in order to ease I.D. beadremoval in the bundling area.

SECTION 6 -- WELD SEAM ANNEALING



A set of 4x500kw frequency welder supplied by Thermatool provide heat to the weld area.

SECTION 7 -- .Air/Water Cooling section (76m/250' in length)In order to remove the heat induced into the tube during the welding process, the tube is first cooled in air toreduce thermal shock then prior to entering the sizing/squaring stands is cooled with water.

SECTION 8 – EXTERNAL/INTERNAL SCARFINGThe burrs inside and outside the pipe will be scarfed properly.

SECTION 9 -- SIZING/STRAIGHTENINGSizing or squaring is performed in the 4-roll stands.These stands are particularly suited to precision sizing ofround tubes and to profiling of square and rectangular hollow sections. All roll assembly movements arecontrolled by the computerized quicksetting system and roll locations are displayed on the operators screens.Straightening of the tubular sections is performed in a universal turks head with rolls that never change. Preciseplane-parallelism of the longitudinal sides of rectangular hollow sections with extreme wide side to narrow sideratios is ensured by the use of cambering stands.

Achieving Results

Enhanced Efficiency• Roll angles are quickly and easily adjusted to provide line contact with the tube surface over the maximumeffective roll profile.• Set up time is minimized through our patented Computer Aided Setting System.

Improved Quality• Hydraulic lift mechanism on the roll entry automatically adjusts roll position to prevent damaging tube ends.• A range of heavy duty style machines provide enhanced rigidity, with consistent straightness and roundness.• The COMPASS software package can provide management, maintenance and quality control information,including: calibration and wear compensation; maintenance information; fault finding; and mimic flow diagrams.

Superior Technology• Unique design allows thin walled tube to be straightened accurately without surface blemishes.• The ability to straighten at speeds up to 200 meters per minute (approximately 600 fpm).• Hydraulic lift mechanism with sensors automatically adjusts rolls to accept upset pipe.• Pressure sensing units may be fitted on each roll to provide an accurate indication of the pressure applied to thetube.

Safety• The drives are set in the back of the machine, away from the operator.• The machine operator has a complete view of the straightening process from the operating console.

SECTION 10 –CUT-OFFThe travelling milling cutter operates with two carbide tipped cut-off blades. The cut-off ensures a very highprecision in regards to length and quality of the end cut for tubes of all dimensions and wall thickness. Standardlengths from 23'-60' are produced with lengths exceeding 63' up to 80' treated as special orders.Flexibility

• O.D. Variations - Can accommodate pipe and tube with O.D. ranges of less than 12 mm (0.5 inches) to over 660mm (26 inches) and crop lengths from a facing cut to 1 meter (approximately 3 feet).

• Operating Method – Can operate in various modes - fully automatic; automatic with manual pipe positionoverride; semi-automatic; and manual.



• Throughput requirements – Can improve productivity with multiple head facing machines, as well ascustomized material handling system.

• Pipe Lengths – Can accommodate any length variation, as well as properly cut random lengths.

• Wall Thickness – Can accommodate essentially any wall thickness required.

Design ExcellenceThe Travelling Milling Cut-Off Machines are specially adapted for cutting line pipe, casing, tubing, rollerbearing and coupling stock.• Our design incorporates a rotating product and stationary tool cutting method.• Automatic ream & chamfer assembly, which can conform to the O.D. or I.D. of the pipe, or cut to a referencecenterline.

• Universal chucking assembly, which handles a range of pipe diameters per tooling set.

• Large main drive motors allow cutting with two tools, each with a wide carbide insert; providing long tool wearlife at cutting speeds over 200 surface meters per minute (approximately 600 fpm).

SECTION 11- End FacingWhile most end facing operations can be effectively accomplished with a single head machine,Bronx/Taylor-Wilson recognized the need for improved productivity associated with high speed cutting lines.Thus, a twin head facing machine for those special applications is introduced:.Achieving ResultsEnhanced Productivity• Set up time is reduced by incorporating remote, computer-driven automatic tool setting with hydraulic toolblock clamps and powered diameter adjustments.

• The machine is built on electronic elevating jack base for vertical adjustment to accommodate varying tubeO.D.

• Top opening pipe clamps and separate alignment stations reduce cycle time.

• Fully automatic equipment operation provided by state-of-the-art Level 1 or Level 2 interface.

• The machines utilize dry carbide cutting tools with surface cutting speeds of up to 200 meters per minute(approximately 600 fpm).Application Flexibility• Superior machine stability due to the fixed head center height design reduces tool chatter and vibration, thusimproving surface finish.

• The pipe is firmly held by hydraulic clamps to reduce tool vibration and provide outstanding surface finish.

• Heavy duty design ensures long life and low maintenance even in arduous steel mill environments

SECTION 12 –HYDROSTATIC TESTINGFlexibilityWhile the principles behind hydrostatic testing remain consistent, each installation has its own uniquerequirements. BRONX/TAYLOR-WILSON designs and produces state-of-the-art systems with the flexibility toaccommodate a host of variables, including:



• O.D. Variations – Can test pipe and tube with an O.D. from less than 150 mm (1 inch) to over 630 mm (24inches). With quick change tooling, can accommodate over a 4:1 variation in O.D. on a single machine.

• End Condition – Can accommodate plain end square cuts, API line pipe ends, threaded ends, as mill sawedends, or pierced ends.

• Pipe Lengths – Can design a system to accommodate any length variation, as well as properly test randomlengths.

• Throughput Requirements – Single head, low pressure testers for off-line use to multi-head (two, three or fourhead), high speed machines for in-line mill applications.

• Operating Method – Can operate in various modes - fully automatic; automatic with manual pipe positionoverride; semi-automatic; and manual.

• Pressure – Can test with stable pressure of 69bars to over 800 bars .

Design Excellence - Sealing.Bronx/Taylor-Wilson has designed and produced an array of sealing devices, to accommodate a wide variety ofapplications based on end conditions, O.D. variations and pressure requirements. Our sealing devices include:

• Traditional U-cup seal with special anti-extrusion hardened ring;

• End sealing for low pressure;

• I.D. sealing for critical high stressed pipes;

• Collapsing seal with traveling insert, which allows a pipe range to be tested by a common seal – for testingunfinished product, or in front of a coupling.

Design Excellence – Pressure Control.Frequently, the test pressure procedure is affected by fluctuating pressures, thereby compromising the testingprocess. By using specially designed intensifiers, either oil-to-water or water-to-water, combined with the latestmicroprocessor-controlled hydraulic servo equipment or electronic air-over-water regulation system, we canachieve greater stability in the test pressure systems. Additionally, the test hold time can be easily varied on ourtesters to suit the specific standard to which the pipe is being tested – all with continuous and accurate pressurecontrol throughout the test hold period.

Achieving ResultsEnhanced Efficiency• Fully automatic testing of a complete API range (1, 2 or 3) of pipe lengths, without resetting the machine.

• An automatic measuring system built into the alignment station to prevent pipes outside of the length tolerancefrom entering the test bed, while simultaneously testing and discharging previous pipes.

• All pipe length, grade and pressure settings are accomplished at the operator control station, without physicaladjustments required.

• Testing mechanisms are designed with drop-in components to rapidly change pipe size or test cups.

• Automatic electronic end length tracking device ensures the quickest cycle time between pipe length variations.

• Alarm diagnostics and maintenance screens for fast and accurate trouble-shooting.



Superior Technology• Self-contained water filtration system to control the test water for trouble free operation.• Internal crane mechanism improves servicing of the system.• Fast and accurate test pressure-build times through the deployment of our specially designed intensifyingsystems.• Data capture by the precise measurement of each pipe can be transmitted though the PLC control and networkto other areas of the finish floor, including drifting station, marking system or bundler.

Safety• Fully enclosed test hood provides protection for personnel and adjacent equipment.• Bullet proof windows in the control station for operator safety.• Optional features such as video cameras for remote operation of the hydrostatic tester for further operator safety.

STEP 13-SEAM USTThe in-line ultrasonic testing system is to test the defects existed in the pipe.

STEP 14- WEIGHING, MEASURING AND STENCILINGEach pipe is weighed, measured, and stenciled for complete identification. Pipe dimensions are compared withdatabase order information including specification, heat number, size, date and time of manufacture before theyare sent to shipping.

STEP 15 –Stock and ShipmentCapable of handling tubes from 20 to 63 feet in length directly from the mill line, the computer operated systembuilds bundles to mill weight and size specifications and then bands, drains and transports the completed bundlesto the warehouse for storage or direct loading to trucks.

Pipe Coating ProductsFusion Bonded Epoxy – Fusion Bond Epoxy is a powder epoxy thermosetting coating applied for anticorrosionprotection to steel pipelines. The pipe is first blast cleaned and heated. Then epoxy powder is spray applied byelectrostatic guns to melt and form a uniform layer that hardens within a minute from application. Utilizing industryaccepted materials supplied by manufacturers such as 3M, DuPont, and Valspar, the facility can apply FBE in a widerange of thickness to cost effectively meet any project specifications.

Fusion Bonded Epoxy with Abrasion Resistance Overcoating (FBE/ARO) – Utilizing two completely separate powdersystems, the facility can produce FBE with an ARO at unprecedented processing speeds using industry acceptedmaterials such as 3M 6352, DuPont 7-2610, and Lilly 2040.

Fusion Bonded Epoxy with High Temperature Resistant Overcoating – Utilizing two completely separate powdersystems, the facility can produce FBE with a high operating temperature resistant overcoating such as DuPont’sNap-Gard Gold and 3M’s 6258.

Fusion Bonded Epoxy with Zap-Wrap Overcoating – The facility is capable of processing line pipe with connections andof applying the Zap-Wrap abrasion resistance overcoating to the ends of each pipe.

Three Layer Polyethylene (3LPE)To improve anticorrosion performance and adhesion, an additional layer of epoxy primer is sprayed onto pipe surfacesprior to the adhesive layer and Polyethylene top layer application. Three Layer Polyethylene is suitable for servicetemperatures from 60°C to 80°C (85°C peaks). Typical coating thickness is from 1-2 mm to 3-5 mm.

Three Layer Polypropylene (3LPP)If a wider service temperature range and high stiffness is required, adhesive and top layers, applied over primer layer,are based on polypropylene instead of polyethylene. Three Layer Polypropylene is suitable for service temperatures upto 135 °C (140°C peaks). Typical coating thickness is from 1-2 mm to 3-5 mm.

Three Layer Polypropylene and PolyethyleneThree Layer applications involve a thermoplastic coating applied to steel pipelines as a form of anticorrosion protection.This mechanical resistance is appropriate when the risk of particularly severe coating damages exist. The Three Layerprocess involved several steps. First, the pipe surface is blast cleaned to remove any external residue from the mill orstorage. It is then heated and sprayed with a Fusion Bond Epoxy (FBE) primer followed by the application of anadhesive copolymer and polyolefin polymers that are wrap extruded, one over the other.
