Description

High frequency straight seam welded pipe unit
This production line is a specialized equipment for producing straight seam welded pipes in industries such as metallurgy, petroleum, construction, transportation, machinery, and vehicles. It uses hot-rolled steel strips as raw materials and produces round and rectangular pipes of the required specifications through cold bending and high-frequency welding methods.
This production line adopts mature, reliable, complete, and economically applicable production processes to ensure that the physical quality, cost, and various consumption indicators of the products reach a relatively advanced level. The products produced have strong competitiveness in terms of quality and price.
Production line process flow:
Raw material (strip steel coil) → uncoiling → storage → passive leveling → forming and rolling → high-frequency welding → removal of external burrs → zinc replenishment → spray cooling → sizing and shaping → rough straightening → cutting to length → pipe collection and bundling.
Straight seam submerged arc welded pipe unit
It is to open and level a steel plate of a certain width after longitudinal cutting and slitting, and then enter the forming machine. The fully automatic and accurate control flexible forming is used, and the steel plate is bent into a circular pipe using rollers. The steel pipe is pre welded using gas shielded welding. Then cut off and perform submerged arc welding on the inner and outer welds of the steel pipe offline. After water pressure testing, flat head chamfering, weld seam and pipe body inspection, qualified submerged arc welded pipes are obtained.
