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.

Round steel is divided into three types: hot rolled, forged and cold drawn. The specifications of hot-rolled round steel are 5.5-250 mm. Among them: small round steel of 5.5-25 mm is mostly supplied in straight strips and bundles, and is commonly used as steel bars, bolts and various mechanical parts; round steel larger than 25 mm is mainly used to manufacture mechanical parts and seamless steel pipe blanks. wait.
