Seamless Steel Pipe

Send Message Request a Quote

The seamless steel pipe is a kind of steel products with hollow section and no seam around. It is largely used for delivering petroleum, natural gas, coal gas, water and some solid materials. In terms of the production process, the weldless steel pipe can be divided into the hot rolled type, cold rolled type, cold drawn type, extruded type, and more.

Features
1. The seamless steel pipe is superior in weldability and compressive strength.
2. It has more excellent performance and higher metal density.
3. The seamless steel tube can be made with irregular cross section.
4. The outside diameter can be very small.
5. Our seamless steel pipe has high precision and can be manufactured with small scale.
6. The cold drawn seamless pipe shows high accuracy and good surface quality.
