Steel pipe refers to the steel with openings at both ends and hollow section, and its length is larger than that of surrounding steel. According to the processing technology, it can be divided into seamless steel pipe and welded steel pipe, RINA grade A floating dock steel. The production methods mainly include hot rolling, cold rolling, extrusion, cold drawing, forging, welding, etc. The size range of steel pipe is very wide, from capillary with small diameter to large diameter pipe with several meters. Steel pipe can be used for pipeline, thermal equipment, mechanical industry, petroleum geological exploration, container, chemical industry and special purpose.
Weathering steel has good resistance to atmospheric corrosion. Although the initial investment cost of weathering steel is slightly higher than that of ordinary carbon steel. Compared with methods such as spraying anticorrosive coating on the surface of ordinary carbon steel, the later maintenance costs of ordinary carbon steel are weathering steel. 1.5-2 times. Therefore, RINA grade A floating dock steel weathering steel can reduce environmental pollution and is a key promotion technology for energy saving and emission reduction. Most domestic weathering steels are painted and used, and their original intentions of no-painting and "rust prevention" have not been exerted to a greater extent.
