Duplex seamless steel pipe

Steel Pipe Pillar Subway Equipment

High quality Steel Pipe is used in a wide variety of applications including water and sewage transmission, outfalls, pile casings, high-spec pipelines and commercial structures.Linings and coatings to suit any project are available, from plain shell, standard polyethylene tape coated, Heat bonded tape, and concrete inner lining, to high spec epoxy builds.
Great strength
Spiral welded Steel Pipe For Subway offers greater strength in proportion to wall thickness of any competitive product. Carbon Steel Pipe operates safely at higher pressures and Steel Pipe strength provides distinct handling and laying advantages in difficult locations. The weld is significantly less affected by circumferential stress than alternative products.
Dependability and longevity
Recent major advances in steel fabricating, welding techniques and coatings development ensure the useful life of the product and, once installed, Construction Steel Pipe can be depended upon to do the job for which Steel Pipe was designed
Ease of laying

Ease of laying due to longer Steel Pipe For Subway lengths, which means less jointing; welded joints provide a pipeline that acts as a structural member.
