Seamless steel tubes for low medium pressure boile Seamless steel pipe

Seamless steel tubes for low and medium pressure boilers (GB3087-2018) are used to manufacture superheated steam tubes, boiling water tubes for low and medium pressure boilers of various structures, and superheated steam tubes for locomotive boilers, large smoke tubes, small smoke tubes and arch brick tubes. High-quality carbon structural steel hot-rolled and cold-drawn (rolled) seamless steel tubes.
Implementation standard of seamless pipe for low and medium pressure boiler: (GB3087-1999)
Manufacturing process:
1. Hot rolling (extruded seamless steel pipe): round tube billet → heating → piercing → three-roll cross rolling, continuous rolling or extrusion → tube removal → sizing (or reducing) → cooling → straightening → hydraulic test (Or flaw detection)→mark→warehousing
Cold drawn (rolled) seamless steel pipe: round tube blank → heating → piercing → heading → annealing → pickling → oiling (copper plating) → multi-pass cold drawing (cold rolling) → billet tube → heat treatment → straightening → water Compression test (flaw detection) → mark → warehousing.
Calculation formula of steel pipe weight: [(outer diameter-wall thickness)*wall thickness)*0.02466=kg/m (weight per meter)
