Instruction

ASTM A53 carbon steel pipe technical standard covers seamless carbon steel pipe for high-temperature service in NPS 1/8 to NPS 48 [DN 6 I to DN 1200] inclusive, with nominal (average) wall thickness as given in ASME B 36.10M. It shall be permissible to furnish pipe having other dimensions provided such pipe complies with all other requirements of this specification. Pipe ordered under this specification shall be suitable for bending, flanging, and similar forming operations, and for welding.When the steel is to be welded, it is presupposed that a welding procedure suitable to the grade of steel and intended use Or service will be utilized.

ASTM A53 2 inch carbon steel pipe sch 10 carbon steel pipe, SCH 10 hot finished seamless carbon steel tubing Size covering :

Size: Outer Diameter: 6-1000 mm,

Wall Thickness: 1- 80 mm,

Length :1-12m or as customers request

Application: High-Temperature Service

Material: 10#.20#.16Mn . A106 (GrB,GrC). ST35-ST52

 

Hot Finished Seamless Tubing Manufacture Method:  

Tubes shall be made by the seamless process and shall be cold drawn.

 

Heat Treatment: 

1)Cold-drawn tubes shall be heat treated after the final cold-draw pass at a temperature of 1 200F [640C] or higher to ensure ductility satis factory for rolling into tube sheets and to meet mechanical properties as specified.

2)If stress -relief anneal of the U-bends is specified, the anneal shall consist of heating the bent portion within a range of 1100 to 1200F [585 to 640C].
