Product introduction

ZHONGXIN IRON AND STEEL
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.
