Description:

The ASTM A513 is a kind of seamless steel pipes and is called Electric-Resistance-Welded Carbon Steel Pipe. This seamless steel pipe has a round section shape.

The ASTM A513 steel pipe has some sorts , for example:ASTM A513 1010,ASTM A513 1020,ASTM A513 1025, ect.

ASTM A513 seamless steel pipe is widely used in Machinery and Automobile.

As an experienced China seamless steel pipe manufacturer, we manufacture our steel pipes according to ISO9001-2000, PED, API, TS16949,KR,LR so that we can be assure of the quality of steel pipes. Besides, we implemented the following inspections and tests: Chemical Composition Inspection, Mechanical Properties Test(Tensile Strength, Yield Strength, Elongation, Flaring, Flattening, Bending, Hardness, Impact Test), Surface and Dimension Test.
