Carbon steel seamless steel pipe is kind of long steel. Steel pipe has hollow section, which is widely used as pipeline for conveying fluids, such as oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, steel pipe is lighter in weight under the same bending and torsional strength. It is an economic section steel. It is widely used in manufacturing structural and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction.

ASTM A519 GR. 1010 Cold Rolled Seamless Steel Tube is low Carbon Steel Tube, which is one of the most commonly used steel pipes for general purpose applications worldwide. It has good weld ability and forming and extruding chrematistics. It also has exceptionally simple and robust mechanism, self-cleaning and non-clogging mechanism, power saving, maintenance free, big solid handling capability, and as well as the quality for enduring reliable longer life and performance. 1010 tubing is often used for general structural and automotive bodies.
