ASTM A106 Seamless carbon steel tube for high temperature service

What is ASTM A106 seamless steel pipe

ASTM A106 seamless pressure pipe is commonly used in the construction of oil and gas refineries, power plants, petrochemical plants, boilers, and ships where the piping must transport fluids and gases that exhibit higher temperatures and pressure levels. It covers seamless carbon steel nominal wall pipe for high-temperature service. Suitable for bending, flanging and similar forming operations. ASTM A106 seamless steel pipe includes two processes: cold drawn and hot rolled. Among them, cold drawn has higher dimensional accuracy than hot rolled, and the surface of hot rolled steel pipe is relatively rough. The large-diameter seamless steel pipe is hot-rolled steel pipe, and the small-diameter is cold drawn.

Manufacturing process of ASTM A106 seamless steel pipe

· Killed steel, with the primary melting process being open-hearth, basic-oxygen, or electric-furnace, possibly combined with separate degassing or refining.

· Steel cast in ingots or strand cast is permissible.

· Hot-finished pipe need not be heat treated.

· Cold-drawn pipe shall be heat treated after the final cold draw pass.

Application of ASTM A106 seamless pipe

· Oil and gas Industry

· Water Industry

· Mineral slurry transmission Industry

· Boiler Industry

· Construction Industry

· Structural purposes Industry

ASTM A106b material properties

Good adhesion, strong corrosion resistance, strong acid, alkali, and other chemical corrosion resistance, non-toxic, non-rusting, wear-resistant, impact resistance, strong permeability resistance, smooth surface of the pipeline, no adhesion to any substances, can reduce the resistance during conveying, improve the flow and conveying efficiency, and reduce the conveying pressure loss.

The coating of a106 seamless pipe has no solvent and no exudate material, so it will not pollute the conveyed medium, so as to ensure the purity and hygiene of the fluid. No aging and no cracking, so it can be used in harsh environments such as cold areas.

A106 material is stainless steel pipe, a106 seamless steel pipe is a kind of seamless steel pipe used to transport high temperature fluids such as water, oil and gas. Mainly used in construction, machining, electrical, petrochemical and other industries.

ASTM A106 seamless steel pipe inspection: 

hydrostatic testing, ultrasonic testing, eddy current testing, magnetic particle testing, impact testing, hardness testing, etc.
