A106 export seamless steel pipe is a steel pipe material commonly used at home and abroad. 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, mechanical processing, electrical, petrochemical and other industries.
ASTM A106 seamless steel pipe is an American standard seamless steel pipe made of ordinary carbon steel series. A106 includes A106-A and A106-B. General seamless steel pipes suitable for transporting fluids, equivalent to domestic GB8163 fluid seamless steel pipes. ASTM A106 seamless steel pipe includes two processes: cold drawing and hot rolling. In addition to the different production processes, the two are different in precision, surface quality, minimum size, mechanical properties, and organizational structure.
American standard ASTMA335 alloy pipe corresponds to steel grades P11, P12, P5, P9, and P91
A335 P11 is a material code issued by ASTM (American Society for Testing and Materials). The corresponding national standard is 15CrMo, an alloy steel material.
ASTM A335 P5 corresponds to domestic alloy steel: 1Cr5Mo. The metal structure of 1Cr5Mo is martensite, which has good oxidation resistance at about 650 degrees Celsius, good thermal strength below 600 degrees Celsius, and good shock absorption and thermal conductivity. It is widely used in steam turbines.
The ASTM A335 standard is mainly used for the design and manufacturing of high-temperature and high-pressure pipeline equipment. It requires steel pipes to have high strength, good reactive corrosion resistance, and good stability. The A106 standard is mainly used for high-temperature, high-pressure and low-temperature piping systems, including steam, water, gas and certain corrosive fluids.
