ASTM A53 Galvanized Scaffolding ERW Seamless Steel Pipe

ASTM A53 Galvanized Scaffolding ERW Seamless Steel Pipe

size: OD:10*20-300*500mm, Dia:0.5-20mm,
Length:3-12m

ASTM A53 Galvanized Scaffolding ERW Seamless Steel Pipe

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;

Chemical components and mechanical property of seamless steel pipe:

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.

Ali Supplier Assessment

Seamless Steel Pipe mills, volume should go through continuous annealing (CAPL unit) to eliminate cold hardening and rolling stress, or batch annealing reach the ASTM A53 Galvanized Scaffolding ERW Seamless Steel Pipe mechanical properties of the corresponding standard specifies. Seamless Steel Pipe surface quality, appearance, dimensional accuracy ASTM A53 Galvanized Scaffolding ERW Seamless Steel Pipe better than hot-rolled plate, and right-rolled thin product thickness is about 0.18mm, so the majority of users favor.
