Product Description:
The spiral welded pipe unit is a standard finalized unit developed and improved by DORCO Heavy Industry on the basis of absorbing the essence of foreign molding technology and combining with the actual situation in China. It is the most competitive and mature unit with technical characteristics of DORCO Heavy Industry.
Features:
The raw materials are strip steel coils, welding wire, and flux. Strict physical and chemical inspections must be conducted before investment.
The head and tail of the strip steel are connected by single or double wire submerged arc welding, and after being rolled into a steel pipe, active submerged arc welding is used for repair welding.
Before forming, the strip steel undergoes leveling, trimming, planing, surface cleaning, transportation, and pre bending treatment.
Using an electric contact pressure gauge to control the pressure of the oil cylinders on both sides of the conveyor to ensure the smooth transportation of the strip steel.
Adopting external or internal control roller molding.
The use of a weld seam gap control device ensures that the weld seam gap meets the welding requirements, and the pipe diameter, misalignment, and weld seam gap are strictly controlled.
Both internal and external welding are carried out using American Lincoln welding machines for single or double wire submerged arc welding, in order to achieve stable welding quality.
Use an air plasma cutting machine to cut steel pipes into individual pieces.
Each batch of steel pipes must undergo a strict inspection system to check the mechanical properties, chemical composition, fusion condition, surface quality of the steel pipes, and undergo non-destructive testing to ensure that the pipe manufacturing process is qualified before it can be officially put into production.
