High pressure pipe 11
What does G mean in 20G high pressure boiler tubes? Answer: G or g stands for Pinyin "pot", G means steel pipe for boiler.
Can 20g high pressure boiler tubes be bent? Answer: The common steel types for pipelines are 20g, SA106C, 12Cr1MoVG, P12, WB36, P22, P91, P92, etc. The first four materials are often processed by cold bending. Cold bending is applicable to steel pipes of all materials. It is the preferred method of bending in the design. However, due to the limitations of the diameter of the mold and the pipe (only limited to the bending of pipes below 150 mm), it is not suitable for large-caliber steel pipes and high-pressure thick walls. Applicable; large-diameter and high-pressure thick-walled carbon steel pipes, stainless steel pipes, alloy steel pipes, and pipes with a bending radius of less than 3 times must be formed by hot bending. The design can be given according to the standard processing requirements.
What is the difference between high pressure boiler tubes and low and medium pressure boiler tubes? High pressure boiler tube use: used for heating surface tube of low and medium pressure boiler (working pressure is generally not greater than 5.88Mpa, working temperature below 450 ℃); for high pressure boiler (working pressure is generally above 9.8Mpa, working temperature is 450 ℃) ～ 650 ℃) heating surface pipes, economizers, superheaters, reheaters, pipes for petrochemical industry, etc .; low and medium pressure boiler pipes: used to make various low and medium pressure boilers, superheated steam pipes, boiling water pipes , Water-cooled wall pipe and locomotive boiler superheated steam pipe, large smoke pipe, small smoke pipe and arch brick pipe. Hot-rolled or cold-rolled (drilled) seamless steel pipes made of high-quality carbon structural steel.
