Water filtering spiral steel pipe
Spiral steel pipe is made of strip steel coil as raw material. The strip is first sent to the welding pipe unit. After multi-roll rolling, the strip is gradually rolled up to form a round tube blank with opening gap. Spiral steel pipe is spiral welded steel pipe made by automatic double wire submerged arc welding process.
