1. Application： The pipes 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．characteristics：
●. 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.
