API JIS DIN ASTM SGS BS En Q195 Q235 Q345 Psl1 3PE SSAW Steel Pipe
SSAW steel 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.
SSAW Steel Pipe Description
Size range:
O.D: Ф323.8-Ф1822.4mm
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

SSAW Steel Pipe characteristics
1. 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;
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.
