ASTM A106 Black Carbon Seamless Steel Pipe
Carbon Steel Pipes (A106 Gr B Pipes) is one of the most common products that are used in the development of gas or oil refineries, petrochemical plants, ships, boilers and power plants.
Product introduction
ASTM A 106 Black Carbon Seamless Steel Pipe
Standard: ASTM A106/A106M
This specification covers carbon steel pipe for high-temperature service.
Application of ASTM 106 Carbon Seamless Steel Pipe:
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.
Manufacturing Process of ASTM A106 Seamless Steel Tube:
ASTM A106 seamless steel pipe are produced either by cold-drawn or hot rolled, as specified.
Hot finished pipe need not heat treated. When hot finished pipe is heat treated, it shall be heat treated at a temperature of 1200°F or higher.
Cold drawn pipe shall be heat treated after final cold draw pass at a temperature of 1200°F or higher.
Details of ASTM A106 Seamless Steel Pipe We can supply:
Manufacture:Seamless process, cold drawn or hot rolled
Cold drawn: O.D.: 15.0~100mm W.T.: 2~10mm
Hot rolled: O.D.: 25~700mm W.T.: 3~50mm
Grade: Gr.A ,Gr.B, Gr.C.
Length: 6M or specified length as required.
Ends: Plain End, Beveled End, Threaded
Mechanical and NDT Tests for ASTM A106 Black Seamless Steel Pipe
Bending Test— a sufficient length of pipe shall stand being bent cold through 90° around a cylindrical mandrel.
Flattening test-although testing is not required, pipe shall be capable of meeting the flattening test requirements.
Hydro-static test—except as allowed, each length of pipe shall be subjected to the hydro-static test without leakage through the pipe wall.
Nondestructive electric test-as an alternative to the hydro-static test, the full body of each pipe shall be tested with a nondestructive electric test.
