The hf welded steel pipe mill line factory believes that the production process of the straight seam welded pipe is simple, the production efficiency is high, the cost is low, and the development is relatively fast. The strength of the spiral welded pipe is generally higher than that of the straight seam welded pipe.
The hf welded steel pipe mill line factory found that the welded pipe with large diameter or thicker is generally made of steel billet directly, while the small welded pipe and thin-walled welded pipe only need to be welded directly by the steel strip. Then simply polished and brushed.
The hf welded steel pipe mill line factory divides welded steel pipes into straight seam welded pipes and spiral welded pipes according to the form of welds. Classification by production method: process classification - arc welded pipe, electric resistance welded pipe, (high frequency, low frequency) gas welded pipe, furnace welded pipe.
Smaller diameter welded pipes use straight seam welding, and large diameter welded pipes are mostly spiral welded; according to the shape of the end of the steel pipe, it is divided into circular welded pipes and special-shaped (square, rectangular, etc.) welded pipes; It is divided into welded steel pipes for mining fluid transportation, galvanized welded steel pipes for low-pressure fluid transportation, and electric welded steel pipes for belt conveyor idlers.
