The main process features of spiral steel pipe are:

A.During the A. forming process, the steel plate has uniform deformation, small residual stress and no 

scratch on the surface. The spiral steel pipe has more flexibility in thesize and specification range of

diameter and wall thickness, especially in the production of high grade thick-walled steel pipe, especially

in the medium and small diameter thickwalled steel pipe with incomparable advantages compared with 

other processes, can meet the user's more requirements in the specifications of spiral steel pipe.

B. Adopting advanced double-sided submerged arc welding technology, the welding canbe realized in the

best position, and the defects such as staggered edge, welding deviation and incomplete penetration are

not easy to occur, so the welding quality can be easily controlled.

C. 100% quality inspection is carried out on the steel pipe, so that the whole process of steel pipe 

production is under effective inspection and monitoring, 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, realizing the real-time data transmission, and the technical parameters in the

production process are controlled by the central control room.
