1.Specification
Pipe O.D: Ф406.4～Ф1422.4mm（16-56in）
Pipe Length: Max.12.2m(40ft)
Wall Thickness: When the steel grade is X70, the wall thickness ranges from 6.4 to
26.4mm(0.252--1.04in);When the steel grade is lower, the wall thickness will be increased
accordingly
Product Standard: ISO3183-3; API Spec 5L, GB9711
Capacity: The annual output is 0.2million tons
2.Application

LSAW Steel Pipe are mainly used as long distance transportation pipeline for oil, gas, liquid
coal etc. on land and offshore. And also can be applied as construction pipes on offshore platform,
power station, petrochemistry and city construction etc.

3.Major characteristics
① The LSAW Steel Pipe internal stress is very small and uniformly distributed after the full- length
expansion. The corrosion and cracking of the pipe owing to stress can be effectively prevented.
The application of welding on site is very easy because of the high dimension precision;
② The inside and outside welding are performed after the tack welding , so the welding process is
very stable with good weld quality;
③ The NDT is easy to perform on the weld during production and field operation as well;
④ The length of the weld is shorter than that of the non-longitudinal seam pipe, so the probability
of defects occurrence is very low;
⑤ The coverage of the pipe specification is very wide. The pipe can be either in very large
diameter with thick wall or in very small diameter with thick wall.
