ASTM A106 Gr. B seamless carbon steel nominal pipe for high temperature use is a long strip of steel with a hollow cross-section and no joints around the periphery. Steel pipes have a hollow cross-section and are widely used as pipelines for transporting fluids. The American standard for seamless steel pipes includes pipelines for transporting petroleum, natural gas, coal gas, water, and certain solid materials. Compared with solid steel materials such as round steel, steel pipes are lighter in weight when their bending and torsional strength is the same. They are an economical cross-sectional steel material widely used in the manufacture of structural and mechanical parts, such as oil drill rods, automotive transmission shafts, bicycle frames, and steel scaffolding used in construction.
ASTM A106 Gr. B Seamless Carbon Steel Specification for High Temperature Service:
The outer diameter of the product is 1/2 “-48”, 21.3-1219.2mm, with wall thicknesses of SCH10, SCH20, SCH30, STD, SCH40, SCH60, XS, SCH80, SCH100, SCH120, SCH140, SCH160, XXS.
ASTM A106b seamless pipes can be divided into hot-rolled pipes, cold-rolled pipes, cold drawn pipes, extruded pipes, etc. according to different production methods. Hot rolled seamless pipes are generally produced on automatic pipe rolling units. The solid tube blank is inspected and surface defects are removed, cut into the required length, centered on the end face of the tube blank perforation, and then sent to the heating furnace for heating, and perforated on the perforation machine. The steel pipes in ASTM A106 standard have no allowable deviation in chemical composition, only double retesting is required. The results must also comply with the chemical composition range specified in ASTM A106 gr. b. Otherwise, it will be judged as an unqualified product. The mechanical function of steel pipes can only be judged through double testing.
ASTM A106 Gr. B seamless carbon steel nominal pipes for high temperature applications belong to seamless steel pipes for high temperature operations. Implement ASME and ASME standards. The correct pronunciation is SA-106 Gr. B, SA must be followed by a “-“, without a “-” is an incorrect pronunciation.
SA106B seamless steel pipe is mainly used as a heating surface pipe for low and medium pressure boilers (with a working pressure generally not exceeding 5.88Mpa and a working temperature below 450 ℃); Used for heating surface tubes, economizers, superheaters, reheaters, petrochemical industry tubes, etc. of high-pressure boilers (working pressure generally above 9.8Mpa, working temperature between 450 ℃ and 650 ℃).
ASTM A106 Gr. B seamless carbon steel nominal pipe for high temperature applications has an outer diameter of 1/2 “-28”, 21.3-711.2mm, and wall thicknesses of SCH30, SCH40, STD, XS, SCH80, SCH160, XXS, etc Seamless pipes can undergo surface anti-corrosion treatment as required, with plastic pipe caps on both ends, can be chamfered as required, and can be inspected for quality.
