Spiral steel pipe


Spiral steel pipe is a spiral seam steel pipe made of strip coil plate, extruded at constant temperature and welded by automatic double-wire double-sided submerged arc welding process. The spiral steel pipe will send the strip into the welding pipe set. After being rolled by a multi-channel roll, the strip gradually rolls up to form a circular tube blank with an open gap. The pressure of the extrusion roll is adjusted so that the weld gap is controlled within 1~3mm and the two ends of the welding joint are flush.

Precision steel pipe


Precision steel pipe is a kind of seamless steel pipe with high precision and high brightness produced by cold drawing or cold rolling process. Its inner and outer diameter size can be accurate to 0.1mm, in order to ensure the bending and torsional strength is the same, light weight, so it is widely used in the manufacture of precision machinery parts.
