Description

GB 3087 Seamless Alloy Steel Tubes For Low Pressure Medium Boiler

GB3087-2008 is used in the manufacture of water wall, economizer, reheater, superheater and steam pipe for low and medium pressure boilers.

The seamless pipe for low and medium pressure boilers (GB3087-2008) is used for the manufacture of superheated steam pipes, boiling water pipes and locomotive boiler superheated steam pipes, large smoke pipes, small smoke pipes and arch brick pipes for various structures. Hot-rolled and cold-drawn (rolled) seamless pipes of high-quality carbon structural steel.

GB3087-2008 "Small and medium pressure boiler seamless steel pipe" provisions. Various types of structural steel pipes for boilers, with an outer diameter of 10 to 426 mm, totaling 43 types. There are 29 kinds of wall thicknesses of 1.5 to 26 mm.

GB3087-2008 "Low-medium-pressure boiler seamless steel pipe" and GB5310-2008 "high-pressure boiler seamless steel pipe" provisions. Appearance quality: cracks, folds, creases, crusting, separation and hairline are not allowed on the inner and outer surfaces of steel pipes. These defects should be completely removed. The clearance depth 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.
