Structural Service

Structural steel pipe refers to the steel pipe mainly used in general engineering structure and mechanical structure. According to the material used, it can be divided into carbon structure tube, alloy structure tube and stainless-steel structure tube. Carbon structural pipes are mainly used in factories, bridges, ships and other buildings, such steel is generally used directly without heat treatment. Because of its high strength and comprehensive mechanical energy, alloy structural pipes are widely used in bridges, ships, boilers, vehicles and important building structures. Structural stainless-steel seamless steel pipe is widely used in chemical, petroleum, textile, medical, food, machinery and other industries corrosion-resistant pipes and structural parts.

According to the manufacturing method can be divided into seamless structure pipe and welded structure pipe. According to the shape can be divided into circular, square, rectangular, oval and other irregular shapes.
