Product Introduction
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.
