ASTM Galvanized Structural Hollow Sections Rectangle Welded Pipes
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;

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.
