Difference between seamless steel pipe and electric welded steel pipe

Changzhou Chengxin Metal Products Co., Ltd. focuses on hydraulic cold drawn pipe and high-frequency welded pipe.

Seamless steel pipes are made of high-quality carbon steel or alloy steel, which can be hot rolled or cold rolled (drawn).

Welded steel pipes are welded from rolled steel plates with butt or spiral seams. In terms of manufacturing methods, they are also divided into welded steel pipes for low pressure fluid transportation, spiral electric welded steel pipes, directly rolled welded steel pipes, electric welded pipes, etc.

Seamless steel pipes can be used in various industries, such as liquid and gas pipelines.

Welding pipe can be used for water pipe, gas pipe, heating pipe, electrical pipe, etc.

Welded steel pipes are divided into furnace welded pipes, electric welding (resistance welding) pipes and automatic arc welded pipes due to their different welding processes. They are divided into straight seam welded pipes and spiral welded pipes due to their different welding forms. Because of their end shapes, they are also divided into circular welded pipes and special-shaped (square flat) welded pipes.
