Large-size thick-walled steel pipes have high strength and bearing capacity, and can withstand greater pressure and external force. It is suitable for some engineering fields with high strength requirements, such as petrochemical industry, natural gas transmission, building structure, etc.
Deep processing of steel pipe refers to the process of further improving and expanding its performance, shape or use through various processing techniques on the basis of steel pipe.
Pipeline steel is a kind of special steel used to transport oil, natural gas and other fluid media.
Prefabricated direct buried polyurethane insulation pipe
The piping system consists of a working steel pipe layer, a polyurethane insulation layer and a high-density polyethylene protective layer.
Steel jacket steel insulation pipe
This piping system is particularly suitable for occasions that require insulation and corrosion protection, such as hot water supply systems, heating systems, etc.
Fbe anti-corrosion is an efficient anti-corrosion technology, which is widely used in the field of pipeline anti-corrosion.
3PE anti-corrosion is a widely used steel pipe anti-corrosion, called 3-layer polyethylene anti-corrosion coating.
