Pipes & tubes of Nippon Steel & Sumitomo MetalPipes & tubes of Nippon Steel & Sumitomo Metal

Nippon Steel & Sumitomo Metal has produced and sold a

complete range of steel products and has served every need in

Japan and overseas for over a long period of time as a compre-

hensive steel manufacturer.

In the pipe & tube unit, we have the latest production facilities

that can cover all products, such as those involving seamlessrolling, electric resistance welding, butt welding, and arc weld-

ing, as well as a product control system based on non-destruc-

tive inspection using computers.

In addition, the comprehensive unique capabilities of Nippon

Steel & Sumitomo Metal include application technologies and

construction technologies varying from high-grade pipes for

lines, oil wells, and power generation, etc., to general pipes &

tubes such as those for piping and structures. We believe that

such technologies will serve you and your needs.

We would like to gain your interest in the pipe & tube products of

Nippon Steel & Sumitomo Metal.

Production process Seamless pipes & tubes (Mannesmann process)

Hot process

Mandrel mill process

After heating the round steel billet, hollow pipes are made with a piercer with toe angle. Then, elongating rolling is per formed

by a mandrel mill, which consists of a multi-step continuous rolling machine, to thereby produce the mother pipe. This mother

pipe is reheated and is then nished by stretch reducing mill to a specied outside diameter and thickness for the nal pr oduct.

Plug mill process

After heating the round steel billet, hollow pipes are made with a piercer. Then, elongating rolling is perform ed through a plug

mill. Pipes are reeled and nished to a specied diameter for nal products. For a pipe & tube with a small diameter, original

pipes with a specied diameter are reheated and then nished to the specied outside diameter and thickness through a reduc-

ing mill for the nal product.

Cold-rolling process

When higher dimensional accuracy and mechanical properties are required compared to pipes produced by the hot-rolling

process, cold drawing subsequent to hot rolling is performed for the nal product.

Seamless pipe production (hot extrusion process)

Hot extrusion process

(Ugine-Sejournet process)

Hot extrusion is a process in which heated billets are

inserted into the cylinder, known as a container, and

extruded with a hydraulic press. The specified outside

diameter and thickness can be obtained with a die and

mandrel. For pipes requiring higher dimensional accuracy

and a surface nish, they are nished through cold rolling

for the nal product.

With this process, fin pipes & tubes or various shaped

steel other than steel pipes & tubes can be produced.

Hot hollow forging process

(Ehrhardt Push Bench process)

Hot forging is a process for producing large-diameter thick

pipes that are used in severe environments, such as main

steam pipes at power plants.

Electric resistance-welded pipes & tubes

Electric resistance-welded pipes & tubes are produced by forming the coil into a cylindrical form with top/bottom and left/right

forming rolls while continuously rewinding the coil to be electric resistance welded.

For a hot-nish electric resistance-welded pipe & tube (SR pipe), a long-size electric resistance welded pipe & tube is heated

in a continuous heating furnace and drawn and nished by a stretch reducer. It is used to produce small-diameter pipes. Fur-

thermore, NSSMC produces PIC (Pipe in Coil) in which the pipe is formed into a coil as a long-size pipe, in particular.

Heat exchanger tubes by cold drawing are also produced.

Butt-welded pipes & tubes (CW), hot electric resistance-welded (SW) pipes & tubes

Butt-welded pipes & tubes (CW) are produced by heat-

ing the coil to a butt-weld temperature through a heating

furnace while continuously rewinding the coil. This heated

coil is put through the forming butt-welding roll to form the

pipe. It is nished to a specied size through a drawing roll

and sizing roll.

Hot electric resistance-welded (SW) pipes & tubes are

produced by electric resistant welding the heated coil and

nishing it to a specied size with a reducing mill.

Arc-welded pipes & tubes

UO process

UO pipes are produced by forming the both ends of the

plate into a groove, forming the groove-shaped steel into

a cylindrical shape with a U press and O press, and then

arc welding the linear joints from the inside and outside

(submerged arc welding).

Bending roll process

Bending rolled pipes have two processes: A press bend

process for nishing pipes & tubes into a cylindrical shape

with a forming press and a bending roll process to rstly

make a circular shape at both edges of the steel sheet

with a bend press, and then to make a perfect cylinder

shape by rolling. The linear joints of a formed shape are

arc welded (submerged arc welding) from the inside and

outside.

Spiral welding process

Spiral welded pipes are produced by bending and forming

a coil into a spiral with a forming roll while continuously

rewinding the coil, and by welding the joints from the inside

and outside.
