ASTM A106 - American Society for Testing and Materials standard, Chinese name: Carbon steel seamless steel pipe for high temperature operations. Corresponding to levels A, B, and C, each has different requirements. A106B is the Chinese material 20# corresponding to the American standard seamless steel pipe.
SA106B seamless steel pipe is the steel used for boiler steel pipes. SA106B is an American brand and is called 20G steel pipe in China.
20G steel pipes are mainly used to manufacture high-pressure and higher-parameter boiler pipe fittings, low-temperature section superheaters, reheaters, economizers and water-cooled walls; such as small-diameter pipes for heating surface pipes with wall temperatures ≤500°C, and water-cooled wall pipes, Economizer pipes, etc., large-diameter pipes for steam pipes with wall temperatures ≤450°C, headers (economizers, water-cooled walls, low-temperature superheaters and reheater headers), pipeline accessories with medium temperatures ≤450°C, etc.
American standard steel pipes include ASTM A53 Gr.B general purpose seamless steel pipes, ASTM A106/A53 Gr.B chamfered chamfered beveled steel pipes, Bs1387-1985 British standard ERW high frequency welded pipes and galvanized pipes. ASTM A333 -40℃-101℃ low temperature seamless steel pipe, ASTM A179 seamless steel pipe for heat exchangers and condensers. Steel pipe length: 5.8m fixed length, 6m fixed length, and up to 12m fixed length, also according to Users need to customize the size. The outer diameter of the product is 1/2″-28″, 21.3-711.2mm, and the wall thickness is SCH30, SCH40, STD, Caps can be chamfered as.
