Qualityfrom start to finish

We demand top quality andoutstanding service from our-selves and our suppliers withthe aim of keeping our custo-mers satisfied in every respect.When selecting our suppliers,we take particular care to en-sure that they are flexible anddependable.

Key to partnering us is the abi-lity to meet the most exactingquality requirements.

But even after we have madeour selection, we constantlycheck on the efficiency andquality of our suppliers.

And we apply these same highquality standards to our ownoperations.

Continuous quality control fromincoming goods to storage tooutgoing goods is a matter ofcourse. Our established qualityassurance procedures guaran-tee our customers the depend-

ability they have come toexpect from us.

Our EN ISO 9001 qualitymanagement system has beencertified by an internationallyaccredited inspection companyand is subjected to regularinternal and external audits.

The right product for every

requirement

To ensure that every seamlessor welded steel pipe/tubemeets the requirements placedon it, selecting the right materi-al quality for the job is essential.

Each material has its own spe-cific properties that make it

particularly suitable for itsintended use.

The various materials havebeen classified in groups in linewith their general applicationareas.

In the following, we present theindividual product groups withthe applicable standards andindicate the materials allocatedto each type of pipe/tube.

Processing at a glance

We not only supply the gradesand dimensions of your choice,we also ensure rapid and flexibledeployment on site with ourbroad processing offering. Thishelps you save time andmoney as time-consuming pre-paration work on site is elimi-nated. The pipes/tubes are

delivered ready-cut for yourproject and can be immediatelyinstalled at the constructionsite.

Cutting

Our cutting center is designedto meet any requirement. Wecut fixed lengths in many differ-ent dimensions up to 850 mmoutside diameter (OD). We canalso produce miter cuts andspecial end shapes in accor-

dance with your specificationsand bills of materials.

Weld seam preparation

Our comprehensive servicesalso include weld seam prepa-ration.

With our profile milling ma-chines we can produce adiverse range of joint geome-tries in all dimensions in accor-dance with customer wishes.

Even the beveling of miter cutsis no problem for us.

In this way we create the prere-quisites for good and secure

joints.

Preserving

Following preliminary treat-ment, the material is blastedwith grade SA 1, 2, 21/2 and 3steel grit in accordance withDIN 55928 Part 4. We then

coat the material either with ashop primer for short-termcorrosion protection or with acoating material suitable for

long-term corrosion protection.A further temporary corrosionprotection option for steelpipes/tubes is oiling.

Coating and lining

Within our broad spectrum ofline pipes, we offer pipes withthe appropriate corrosion-protection coating or lining for

various areas of application.

Thread cutting

In the household installationsector, we can machinethreads into pipes up to 4.The pipes and threads aredesigned to withstand an inter-nal pressure of up to 6 bar.

Bending

We can supply custom-bentsteel pipes with single or multi-ple bends in a wide range ofmaterial grades for use as linepipes. Any bending radii from200 to 10,000 mm, withangles up to 180 are possible.The ends can be machined torequirements.

Complete pipelines from a single source.Pipes and accessories for all media andpressure levels. Just ask.

The framework conditions for standardi-zation and technical regulations are cur-rently changing significantly for fabrica-tors of pipes and accessories. TheEuropean Pressure Equipment Directive(PED) has replaced the previousPressure Vessel Code and new EN stan-dards have replaced the previous DINstandards. In addition, previous techni-cal regulations such as the TechnicalRules for Pressure Vessels Pipes(TRR), Technical Rules for PressureVessels (TRB) and the Technical Rulesfor Pressure Vessels Steam Boilers(TRD) are now invalid for new installa-tions. They have been replaced by the

standardized EU-wide technical regula-tions EN 13480 Metallic IndustrialPiping, EN 13445 Unfired PressureVessels and EN 12952 Water-tubeboilers and auxiliary installations and12953 Shell Boilers.

However, repairs and maintenance forexisting equipment are still carried outin accordance with the previous TRR,TRB and TRD regulations, meaning thatEuropean and German standards willexist in parallel and have to be ob-served for some time to come. For thisreason, you will receive pipes certifiedto both the previous DIN and new ENstandards in the future.
