Steel pipe knowledge: What is SA106B seamless pipe

SA106B seamless pipe knowledge: According to different production methods can be divided into hot-rolled pipe, cold-rolled pipe, cold-drawn pipe, extruded pipe and so on. Hot-rolled seamless pipes are generally produced on automatic pipe mills. Solid billets are inspected and the surface defects are removed, cut to the required length, centered on the perforated end face of the pipe blanks, and sent to the heating furnace for heating on the perforating machine. Perforation, continuous rotation and advancement at the same time as the perforation, under the action of the roll and the head, gradually forming a cavity inside the tube blank, said the capillary tube, and then sent to the automatic tube rolling machine to continue rolling, and finally the entire machine is thick, determined Diameter caliber, to meet specifications.
SA106B seamless pipe classification
a. Supply by chemical composition and mechanical properties
b. Supply according to mechanical performance
c. Supply by hydrostatic test
SA106B seamless pipe is mainly used for heating surface pipes of low and medium pressure boilers (work pressure is generally not more than 5.88Mpa, working temperature below 450°C); for high pressure boilers (work pressure is generally above 9.8Mpa, working temperature is 450 °C ~ 650 °C between the heating surface of the pipe, economizer, superheater, reheater, petrochemical industrial pipe.
Seamless pipe weight calculation formula: [(outer diameter - wall thickness) * wall thickness] * 0.02466 = kg/meter (weight per meter)
