Seamless pipe is a long strip of steel with a hollow section and no seams around it. According to the cross-sectional shape, seamless pipes can be divided into circular steel pipes, square steel pipes, special-shaped seamless steel pipes, rectangular seamless pipes, etc. Seamless pipes are widely used in fluid transportation, boiler manufacturing, engineering machinery and other fields due to their unique structure and properties.

Welded steel pipe is divided into straight seam welded pipe and spiral welded pipe according to the form of weld.
Classification by production method: Process classification - arc welded pipe, resistance welded pipe, (high frequency, low frequency)
gas welded pipe, furnace welded pipe.
According to different materials and uses, it is divided into welding steel pipes for mining fluid transportation, galvanized welded steel 
pipes for low pressure fluid transportation, and electric welded steel pipes for belt conveyor rollers.

Square and rectangular tubes are rolled from strip steel after processing. Generally, the strip steel is unpacked, flattened, curled, and welded into a round tube, which is then rolled into a square tube and then cut to the required length. It is widely used in machinery manufacturing, construction industry, metallurgical industry, agricultural vehicles, agricultural greenhouses, automobile industry, railways, highway guardrails, container frames, furniture, decoration and steel structure fields.
