Technology guarantee:
One winding machine can wind multiple pipes at the same time, which improves work efficiency and guarantees product quality.
The winding of pipe fittings (flange, elbow, tee, coupling) is composed of a two-axis winding machine.
Quality control testing:
The following items are selected to proceed:
Pipe stiffness test
Flexure experiment
Circumferential and axial strength test
1.5 times pressure water pressure test (only applicable to pipelines above PN6)
