ASTMA53

Fecha:2017-12-25    Vista:409  Tag:ASTM A53

ASTM A53 is for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless.

ASTM A53 contains seamless steel pipe and welded steel pipe black and hot-dipped galvanized steel pipe in NPS 1/8 to NPS 26. The steel categorized in this standard must be open-hearth, basic-oxygen or electric-furnace processed and must have the following chemical requirements: carbon, manganese, phosphorus, sulfur, copper, nickel, chromium, molybdenum, and vanadium. The tubing shall undergo a seamless or welding process. Tension, bend, and flattening tests shall be performed to make sure that it must adhere to the mechanical properties of the standard. 


ASTM A53 application 
1 Architecture: maximum pipeline under more groundwater extraction when towers, boilers, hot water conveyance and so on. 
2 Machining, bearing sets, processing machinery and other accessories. 
3 Electrical class: gas distribution, water power fluid conduit. 
4 Anti-static tubes wind power plants.


ASTM A53 covers the following types and grades:

Type F—Furnace-butt-welded, continuous welded Grade A,
Type E—Electric-resistance-welded, Grades A and B, and
Type S—Seamless, Grades A and B.
