Spiral welded steel pipe(SSAW, SAWH pipe) production line

The spiral welded steel pipe production line mainly includes a series of special machinery, which is used for the continuous processing from steel coil raw materials to finished pipes. Core equipment can be classified into three major categories: pretreatment, forming and welding, inspection and post-processing.
Pretreatment equipment ‌ :
Uncoiler ‌ : used for uncoiling steel coils and conducting preliminary processing.
Leveling machine ‌ : It flattens the steel plate through roller shafts to ensure a smooth surface.
Shearing butt welding device ‌ : It shears and welds the ends of steel plates to achieve continuous supply of coil materials.
Edge milling equipment ‌ : It is used to mill the edges of steel plates to improve the quality of subsequent welding.
Forming and welding equipment ‌ :
Delivery machine ‌ : As the traction core of the production line, it drives the steel plate into the forming stage.
Forming unit ‌ : The core component for rolling steel plates into a spiral shape.
 Double-sided submerged arc welding machine ‌ : synchronously complete the welding of inner and outer weld seams during the forming process.
 Cutting equipment (such as plasma spray guns) ‌ : precisely cut and formed steel pipes to the set length.
 Detection and post-processing equipment ‌ :
 X-ray flaw detector ‌ : to detect porosity or slag inclusion defects in welds.
Hydrostatic testing machine ‌ : to test the sealing performance and overall strength of pipelines.
Bevel processing equipment ‌ : Perform bevel cutting on the pipe ends to facilitate connection. ‌
