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.

Applications:
High and low pressure fluid conveying pipes: high strength, able to
withstand large impact forces, smooth inner walls, and high
transportation efficiency.
Pile pipes for urban construction: used for supporting and framing
building structures to ensure project safety and stability.
Industrial structural pipes: resistant to high temperature and
corrosion, can be used in harsh environments, and have a short
construction period.
Electricity/heat/gas pipelines: not easily deformed or broken, long
service life, strong sealing, ensuring safe operation of pipelines.
