Piling pipe surface treatment process:
1. The surface-treated steel sheet piling pipe manufacturers to avoid the formation of oxide scale and unwinding process of formation should be established plate cleaning device.
2. The edge steel processing, pipe piling side set up rusting and deburring means to reduce the porosity may arise. Removing device is installed in the best position of milling machine, cutting disc, the device structure is the location of a surface fluctuations can adjust the gap capstan, fluctuating pressure plate edges.
3. Weld profile, weld coefficient is too small, narrow and deep weld gas and inclusion is not easy come, easy to form pores and slag. General weld coefficient control 1.3 - 1.5, thick-walled pipe welding maximum, minimum thin walls.
4. Reduce the secondary magnetic field in order to reduce the influence of magnetic blow, to make the position of the workpiece welding cable connection only from the welding terminals to avoid some welding cable secondary magnetic field on the workpiece.
