Large diameter straight seam steel pipe technological process and main equipment
In order to change the roundness of the steel pipe, the steel pipe finishing machine: apply strong pressure from the outside to the long round pipe with poor roundness section by section, so that it can meet the relevant specifications and use requirements.
Gantry mobile sensor straightening machine: used for straightening steel cylindrical tube.
Straight seam steel pipe chamfering machine: chamfer the ends of straight seam steel pipe according to the specified blunt edge and groove angle.
Improve the dimensional accuracy of steel pipes. Steel pipe diameter expander: eliminate stress.
Check the steel pipe for penetration defects under the specified pressure. Hydrostatic testing machine: Hydrostatic testing of welded pipes.
Able to detect longitudinal and lateral defects and thermally affected differentiation layer defects. Line wave testing equipment: 100% line wave nondestructive testing is performed on all welds.
