Q235A Q235B Welding Steel Tube Pipe Low Carbon Spiral Steel Pipe
Q235A Q235B Spiral Steel Pipe Product Desription
Spiral steel pipe is made of strip coil as raw material, extruded at regular temperature and welded by automatic double wire double submerged arc welding process. The spiral steel pipe will feed the strip into the welding tube unit, and the strip will be rolled up gradually to form a circular tube blank with open gap after rolling by multiple rolls. The pressure down of the extrusion roll will be adjusted so that the weld gap is controlled within 1~3mm and both ends of the welding joint are flush.
Q235A Q235B Spiral Steel Pipe Process Characteristics
A. In the process of forming, the steel plate has uniform
deformation, small residual stress and no scratch on the surface.
The processed spiral steel pipe has greater flexibility in diameter
and wall thickness size and specification range, especially in the
production of high steel grade thick wall pipe, especially in small
and medium caliber thick wall pipe has incomparable advantages in
other processes, can meet the user's more requirements in spiral
steel pipe specifications.
B. Adopting advanced double-sided submerged arc welding technology,
welding can be realized in the best position, and it is not easy to
have defects such as wrong side, welding deviation and incomplete
welding, and it is easy to control the welding quality.
C. 100% quality inspection of steel pipe is carried out, so that
the whole process of steel pipe production is effectively detected
and monitored, and the product quality is effectively guaranteed.
D. All the equipment of the whole production line has the function
of networking with the computer data acquisition system to realize
real-time data transmission, and the technical parameters in the
production process are checked by the central control room.
