What difference between Pindee Pipe welded and Pindee Pipe seamless?

Pindee Pipe manufacture and export Seamless steel pipe and welded steel pipe which they are manufactured by the round steel billet, through hot rolling, cold rolling or cold drawn processes,without seam on the body of the pipe.Welcome to Pindee to purchase stainless steel to our email address:sales@pindee.com

Pindee Pipe is manufactured by flat steel plate, with welding seam on the body of the pipe.

How Pindee Pipe made Seamless steel pipe.

API 5L GRB Seamless steel pipe and A106 GRB Seamless Steel PIPE adopts steel ingot or solid tube as raw material through the perforated tube, API 5L GRB Seamless steel pipe,then can be formed by cold rolled or cold drawn and hot rolled.

Cold drawn seamless pipe used cold-drawn forming technology. The material strength is relatively low, the appearance and internal control surface is smooth. Small diameter and thin wall seamless pipe usually made in this way.Hot rolled seamless steel pipe is formed by billet forging, perforation, rolling, shaping and other processes.one of the Large diameter pipe, and thick walled seamless pipe usually made in this way.

The seamless steel pipes are rolled by carbon structural steel, low alloy structure steel or alloy structure steel and stainless steel. Seamless steel pipes applied in different industries: Line pipe for pipelines, thermal services, mechanical industries, chemicals etc.

How Pindee Steel pipe made Welded steel pipe.

API 5L or ASTM welded steel pipe includes LSAW steel pipe, SSAW steel pipe, and ERW steel pipe. These pipes are made with steel strip or steel plate. The manufacturing processes first bending the steel plate, then welded into circular, square and other shapes. Welded steel pipe has the characteristics of high production efficiency, low cost and saving material. It has been widely applied to aviation, aerospace, energy, electronics, automobile, light industry and other industries. With strong corrosion resistance in the acidic environment.
