Classify

According to production methods, steel pipes can be divided into two categories: seamless steel pipes and welded steel pipes. welded steel pipes are referred to as welded pipes for short.

Seamless steel pipes can be divided into hot rolled seamless pipes, cold drawn pipes, precision steel pipes, hot expanded pipes, cold spun pipes, and extruded pipes according to production methods.

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

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. Due to their different welding forms, they are divided into straight seam welded pipes and spiral welded pipes. Due to their end shapes, they are further divided into circular welded pipes and special-shaped (square, flat, etc.) welded pipes.

Welded steel pipes are formed by welding steel plates rolled into tubular shapes with butt or spiral seams. In terms of manufacturing methods, they are further divided into welded steel pipes for low pressure fluid transportation, spiral welded steel pipes, directly rolled steel pipes, and electrically welded pipes. Seamless steel pipes can be used in various industries such as liquid gas pipelines and gas pipelines. Welded pipes can be used for water pipelines, gas pipelines, heating pipelines, electrical pipelines, etc.
