Description

The 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;
The inside and outside welding are performed after the tack welding , so the welding process is very stable with good weld quality;
The NDT is easy to perform on the weld during production and field operation as well

The length of the weld is shorter than that of the non-longitudinal seam pipe, so the probability of defects occurrence is very low;
●The coverage of the pipe specification is very wide. The pipe can be either in large diameter with thick wall or in small diameter with thick wall.
