Most recent order to Nepal – ASTM A106 GR.C

The A106 standard refers to the ASTM A106/A106M standard, which is a product standard for seamless carbon steel pipes issued by the American Society for Testing and Materials (ASTM International). This standard specifies the requirements for the use of seamless carbon steel pipes under high temperature and high pressure conditions.
The Sa-106 standard applies to high-temperature service environments in general industries, such as petroleum refining, chemical industry, power stations, boilers, heating and high-pressure piping systems and other fields. It covers several grades of carbon steel pipe, including A, B, and C grades.
According to the A106 standard, seamless carbon steel pipes should have certain chemical composition and mechanical properties. The chemical composition requirements mainly include carbon content, manganese content, phosphorus content, sulfur content and copper content. Mechanical property requirements include tensile strength, yield strength, and elongation, among others. In addition, the size, weight and permissible deviations of the pipes are specified.
The A106 standard requires that seamless carbon steel pipes should be able to withstand stress under high temperature and high pressure conditions, and have excellent corrosion resistance and hydrogen cracking resistance. Its manufacturing process includes cold drawing, cold rolling, hot rolling or thermal expansion, etc., to ensure that the inner and outer surfaces of the pipe are smooth and free of defects.
According to the provisions of the A106 standard, seamless carbon steel pipes should undergo a series of inspections and tests such as chemical analysis, mechanical performance testing, visual inspection, wall thickness measurement, pressure test and non-destructive inspection to ensure their quality meets the standard requirements.
In conclusion, the A106 standard is an important seamless carbon steel pipe product standard, which specifies the chemical composition, mechanical properties and manufacturing process requirements of carbon steel pipes, as well as quality control and inspection requirements. Compliance with this standard can ensure the reliable use of seamless carbon steel pipes in high temperature and high pressure environments.

The difference between ASTMA106GrB and ASTMA106GrC
The difference between ASTM A106 GrB and ASTM A106 GrC: the tensile strength is different.
ASTM A106 GrB strength grade 415MPa . ASTM A106 GrC strength grade 485MPa.
ASTMA106GrB and ASTMA106GrC have different carbon content requirements
A106GrB carbon content≤0.3, A106GrC carbon content≤0.35
ASTM A106 GrB. Seamless steel pipe corresponds to the national standard
ASTM A106Gr.B seamless steel pipe is a widely used low carbon steel, which is widely used in petroleum, chemical and boiler industries. The material has good mechanical properties.
