The use of boiler seamless pipe

1 The general boiler seamless pipe is mainly used to manufacture water-wall pipes, boiling water pipes, superheated steam pipes, superheated steam pipes for locomotive boilers, large and small smoke pipes, and arched brick pipes.
2 The high-pressure boiler seamless pipe is mainly used to manufacture superheater tubes, reheater tubes, air tubes, and main steam tubes of high-pressure and ultra-high-pressure boilers.
3GB3087-82 "Seamless boiler for low and medium pressure boilers" and GB5310-95 "high pressure boiler seamless steel pipe" provisions. Appearance quality: No cracks, folds, pleats, scabs, delaminations, and hair lines are allowed on the inner and outer surfaces of steel tubes. These defects should be completely removed. The depth of clearance shall not exceed the negative deviation of the nominal wall thickness, and the actual wall thickness at the cleaning site shall not be less than the minimum allowed by the wall thickness.
Boiler seamless management theory weight calculation method: (outer diameter - wall thickness) * wall thickness * 0.02466
