Natural Gas Pipes 762*7.92*12000mm Api 5l Gr.b

Following are the Main Features of Natural Gas Pipes 762*7.92*12000mm API 5L GR.B :-
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;
