LSAW Steel Pipe
The LSAW steel pipe is a longitudinally submerged arc welding steel pipe whose weld seam is parallel to the longitudinal direction of the steel pipe, used for oil, gas, water transmission, engineering, offshore projects.
As a responsible LSAW steel pipe manufacturer in China, TOPPER provides longitudinally submerged arc welding steel pipe with simple production process, high production efficiency, low cost and high quality. Our LSAW pipes destroy the ingot casting structure, refine the grain of the steel, and eliminate the defects of the microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the lsaw steel pipe is no longer an isotropic body to a certain extent; bubbles, cracks and looseness formed during pouring can also be welded under high temperature and pressure.
LSAW steel pipes follow the specifications as below:
Standards:
API 5L: GR B, X42, X46, X56, X60, X65, X70.
ASTM A53: GR A, GR B, GR C.
EN: S275, S275JR, S355JRH, S355J2H.
GB: Q195, Q215, Q235, Q345, L175, L210, L245, L320, L360- L555.
API 5L PSL1, API 5L PSL2, ASTM A53, ASTM 572, ASTM A252, AN/NZS 1163, AN/NZS 1074, EN 10219-1, EN 10217-1, DIN 2458, IS 3589, GB/T 3091, GB/T 9711, ect.
Wall Thickness: 0.276-1.969 Inch, 7-50mm or customized.
Outer Diameters: 8.622-63.976 Inch, 219mm-1625mm or as requested.
Length: 5.8m, 6m, 11.8m, 12m, up to 12m or as requested.
With the added support of industry specialized engineering teams to help design, build, and manage projects, Topper is able to facilitate the customer's LSAW steel pipe and piping system needs.
