Preface

Steel Corporation has been manufacturing Oil Country

Tubular Goods (OCTG) since 1971, during that time we have accumu-

lated extensive expertise and experience giving their customers great

confidence and satisfaction when purchasing JFE Steel OCTG.

In the past the well conditions in Oil and Gas drilling were relatively mild

and development was straight-forward. Today's Oil and Gas Industry has

become a much more complicated operation as Engineers continue to drill

deeper wells in harsher environments, encountering higher well bore

pressures and temperatures in addition to sweet and sour gas.

To meet these ever increasing industry demands, JFE has developed

its KO series OCTG which has higher collapse resistance, yield strength,

toughness and corrosion resistance, than standard API OCTG material.

Especially, JFE's 13Cr OCTG has established an excellent reputation

world-widely in terms of quality and manufacturing capability.

In the early 1980s, JFE developed the FOX premium connection which

has now gained industry acceptance world wide. And the late 1990s,

JFE has also developed a new premium connection called KSBEAR

designed to meet todays toughest well condition. With these two

connections, JFE can offer customers a choice of products to suit their

various applications.

This OCTG brochure provides you with our ardent desire to assist you

in choosing the correct Oil Country Tubular Goods for your operation.

JFE Steel has been involved in the steel making busi-ness nearly one(1) hundred years and contributing to the industry with its technology. The Top and Bottom Gas Blowing system followed by Continuous Casting is a typical case, which was first introduced to the industry by JFE Steel.

JFE Steel revealed their technical advancement in the pipe manufacturing process. Recently, the process to roll 13Cr steel by the Mannessman piercing mill was realized first in JFE Steel.

All JFE OCTG's are inspected nondestructively for detection of internal and external imperfections by use of Eddy Current, Electromagnetic, Ultrasonic and/or Magnetic Particle method. These requirements play an important role in our rigid quality control and assurance system.

JFE Steel boasts a wide range of testing facilities and equipment to evaluate new and existing products. The benefits generated as a result of this R & D work contribute to our customers and the industry as well as to our daily production activities.

JFE has established foreign offices and service cen-ters throughout the world as listed on the back cover sheet.

JFE Steel ensures consistently high quality for all

its tubular products by way of production control at

every stage from blast furnace to pipe mill, using

inspection systems with advanced ultrasonic,

electromagnetic and other non-destructive inspection

equipment. Pipe production at JFE Steel is part of a

fully integrated steelmaking facility. This means JFE

tubular products are manufactured from beginning to

end under single-maker responsibility for quality and

performance.

OCTG is produced at Chita Works, which

specializes in pipe and tubes under the company's

well-known rigid quality control and assurance

systems.

Equipped with complete mass production systems for

all kinds of pipe and tubular products, Chita is one of

the foremost tubular products centers in the world.

The location of Chita has the advantage of easy

access to West Japan Works which supplies Chita

Works with steel materials for the production of their

tubular products.

4. Manufacturing Process

6

Seamless Mill Electric Resistance Weld (ERW) MillSeamless pipes and tubes are produced either by the mandrel mill or the plug rolling mill process. The former process is used for producing small-diameter pipes up to 7" and the latter for medium-diameter pipes over 7". On either type of mill, each heated billet is pierced through its center on a piercing mill. The pierced billet then moves on to a mandrel or plug rolling mill where it is rolled with a mandrel bar or pluginserted in it. After withdrawal of the mandrel or the plug, the rolled shell is reheated before being pro- cessed on stretch reducing mill or sizing mill where the desired OD and wall thickness are obtained. To ensure consistently high quality, the company con-ducts through testing and inspection, using advanced equipment including eddy current, ultrasonic, electromagnetic and magna flux devices.

Electric Resistance Weld pipes are made from strip in coil form. 12-3/4" and above Mill in Chita Works and 8" and above Mill in Keihin Works produce ERW OCTG pipes.These mills are equipped with high frequency electric resistance welder to provide improved seam quality. And seam heat treatment system after welding helps to get better metallurgical structure.

(a) Process of Manufacture and Heat Treatment Seamless, quenched and tempered

(b) Chemical Requirements

With a recent increase in deep well drilling, there is a growing need for high collapse casing in a minimum yield strength of 95 ksi (655 MPa) grade. Collapse resistance is affected by yield strength, deviation of wall thick-ness, roundness, residual stress and D/t (D for outside diameter and t for wall thickness).Reducing the deviation of wall thickness at hot rolling, control-ling yield strength by closely reg- ulating heat treatment conditions,and minimizing the deterioration of roundness and straightness during cooling are performed. This process is governed by our special techniques and knowhow. By using the same material as that for KO-95T, JFE Steel man-ufactures KO-110T which has higher collapse resistance prop-erties than KO-95T.

2) Deep Well Service

Drilling of deep wells in excess of 15,000 feet and high-pressure gas wells is on the increase. P-110's burst pressure, collapse resistance and tension are not always sufficient for these applications. Therefore, KO-125V casing and tubing and KO-140V casing have been developed. Cr-Mo-Cb steel with excellent hardenability and high temperature resistance are used to make OCTG which have superb strength, toughness, and restricted varia-tion of HRC.

Sour servicesKO-80S, -85S, -90S, -95S and -110S for continuous operating temperature above 149 F (65 C)

Special sour servicesOCTG for sour wells must above all have improved resistance to sulfide stress cracking (SSC) in fluids containing H2S. Intensive research has led to a modified Cr-Mo-Cb steel for OCTG for sour wells. This steel features both excellent hardenability and good temper resistance. Consequently, fine and homogeneous tempered martensite with lower HRC25 for 95 ksi grade is obtained after tempering at higher tempering temperature. As a result, OCTG of these grades possess excellent resistance to SSC for its strength grades.These OCTG are subjected to more stringent quality control. SSC-resistant steel of these grades thoroughly tested by major oil compa-nies enjoys high ratings and is now widely used for sour gas and oil wells all over the world.

4) Low-Temperature Service


Representing the casing and tubing to be used in frigid zones, this series is designed with increased resistance for low-temperature impact in order to withstand shock during delivery, handling, storage, make up, and running in frigid zones. Quenching and tempering is performed to ensure both high yield strength and good low-temperature toughness. Note that the Charpy impact test data of KO-125L with heavy wall of 0.725 in. below show good results at – 50 F. Tensile test results and variation of HRC also show good properties.

In oil and gas fields being looked to for future development, gas which includes CO2 is an increasingly common occurrence. Corrosion has become the major problem for production strings used in environments including CO2, and there is a great demand for a tubing that has strong resistance to CO2 cor-rosion. JFE Steel's KO-13Cr is a mertensitic stainless steel which combines high performance in such kind of corrosive condition with low cost. For fields with more severe conditions such as high temperature and containing not only CO2 but small amounts of H2S, JFE Steel developed KO-HP-13Cr (HP1 and HP2) material which has higher strength and outstanding anti-corrosion property. It also shows excellent low-temperature toughness.

In today's oil & gas industry, companies are drilling deeper high–deviation wells into high pressure reservoirs using the latest generation of drilling rigs and tools. As a result, the loads placed on OCTG connections in certain well conditons exceed those of an API class–1 qualified connection. KSBEAR has been designed and tested to withstand today's toughest well conditions.
