Seamless Pipe
ASTM A106 Seamless Pressure 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.

Packing and delivery
Steel having a hollow section whose length is much greater than its diameter or circumference.According to the section shape is divided into round, square, rectangular and special-shaped steel pipe; According to the material is divided into carbon structural steel pipe, low alloy structural steel pipe, alloy steel pipe and composite steel pipe; According to its use, it is divided into pipe transportation,engineeringstructure, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, steel pipe with high pressure equipment, etc. According to the production process, it is divided into seamless steel pipe and welded steel pipe. The seamless steel pipe is divided into hot rolled and cold rolled (drawing) two kinds, and the welded steel pipe is divided into straight welded steel pipe and spiral welded steel pipe.
