The industry needs to continuously innovate, popularize seamless welding groove technology, and improve construction practice measures.

Carbon is the main element second only to iron in the steel used for seamless steel pipes. An appropriate amount of silicon can improve the strength of steel without significant adverse effects on plasticity, toughness, cold bending performance and weldability.

The principle of plasma cutting seamless pipes is to use the high energy density and instantaneous high temperature of plasma to melt the seamless pipes to achieve cutting, welding and other processes.

Because TIG welding has good welding quality and is easy to operate, in recent years, it has become a common method for power generation companies to weld heating surface  seamless pipe when installing and overhauling boilers.

Attention should be paid to the preservation of cold-drawn seamless pipes.

Cold-drawn bright pipe is a high-precision steel pipe material that has been fine-drawn or cold-rolled.
