Carbon Steel Pipes

CARBON STEEL PIPES

A carbon steel pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow — liquid and gases (fluids), slurries, powders, masses of small solids. It can also be used as steel structure and supports. Our Pipes are available as Pre-Painted, Galvanized or GI Pipe, Bare (not coated), or even with Special Coating and Lining.

Common Steel Grades:

  • Most commonly used specs are ASME / ASTM A106 Grades A B or C, API 5L Gr.B SA/ASTM A53-B; SGP; ASTM A333Gr.6/3; APL 5L X42, 52, 60, 65, 70; ASTM A139 (Spiral Pipe); ASTM 795, and MANY OTHERS.

Types of Pipe by Construction:

  • Seamless Pipe, ERW Pipe, LSAW Pipe (Straight Weld Pipe), SSAW Pipe (Spiral Welded Pipe)

Carbon Steel Seamless Pipe (SMLS Pipe)

  • Seamless (SMLS) pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. As the manufacturing process does not include any welding, seamless pipes are perceived to be stronger and more reliable, Historically seamless pipe was regarded as withstanding pressure better than other types, and was often more easily available than welded pipe.

Carbon Steel Welded Pipe

  • Welded Pipe is manufactured by rolling metal and then welding it longitudinally across it’s length, therefore welded pipes have a welded joint in it’s cross section. it can be ERW, EFW, LSAW, SSAW

Carbon Steel Pipe Origin
