Seamless steel tubes for low and medium pressure boilers (GB3087-2018) are high quality carbon structural steel hot-rolled and cold-drawn (rolled) seamless steel tubes, which are used for manufacturing superheated steam pipes, boiling water pipes for various structures of low and medium pressure boilers and superheated steam pipes, big smoke pipes, small smoke pipes and arch brick pipes for locomotive boilers.

The ends of the steel pipe should be perpendicular to the axis of the steel pipe, and burrs should be removed.GB3087 standard steel pipe is generally made of 10, 20 hot rolled or cold rolled high quality carbon structural steel, usually need water pressure, crimping, flaring, flattening and other tests to ensure product quality and performance.
