Mechanical structure pipe
Mechanical structural pipes are mainly used for various purposes such as mechanical processing, coal mining, hydraulic steel, etc.
Mechanical tube
Hot rolled,Honing,Precision
Mechanical pipes can be delivered in hot rolled state, or processed into honing, cold rolling precision according to customer needs, and delivered through Q+T or normalizing heat treatment. Hot rolled seamless steel pipes are used in the mechanical processing industry, automotive axles, building structures, and other applications.
