Work process:

Upper pipe → align → chain transport to the water pressure center → clamp → fixed and mobile end test head extends to seal both ends of the steel pipe → low-pressure water fills with water, exhausts → closes the water filling valve and exhaust valve → pressurizes → Protects pressure→Relieve pressure→Retract the fixed and mobile end test head→Clamp loose→Send the steel pipe out of the chain→empty water→discharge

 

Automatic palletizing machine

This machine is used to collect, stack steel pipe into 6 or 4 angles, and bundle automatically. It runs stably without manual operation. Meanwhile, eliminate the noise and knocking of shock of steel pipes. Our packing line can improve your pipes quality and production efficiency, reduce cost, as well as eliminate potential safety hazard.
