Common faults of custom api pipe production line

2022-06-01


In the process of customizing the api pipe production line, due to various reasons such as the operator is not skilled in the process and machine operation, the outer surface of the plastic pipe is often rough, the inner vibrating ring appears, the wall thickness is uneven, and the roundness is not enough. Only by adjusting the process in time and eliminating the failure of the plastic pipe production line can the product quality be improved.

api pipe production line

  1. The outer surface of the plastic pipe is rough when customizing the api pipe production line

  Customize the api pipe production line to adjust the process temperature; reduce the cooling water temperature, the best cooling water temperature for the PE pipe is 20-25 °C; check the water channel for blockage or insufficient water pressure; check whether the heating ring such as the barrel and the head is damaged;

  2. Grooves appear on the outer surface of the plastic pipe

  Customize the api pipe production line to adjust the water pressure of the sizing sleeve, and the water output needs to be balanced; adjust the angle of the nozzle in the vacuum setting box to make the pipe cool evenly; check whether there are sundries, burrs, etc. in the die, sizing sleeve, cutting machine and other hardware;

  3. Groove marks appear on the inner surface

  Customized api pipe production line to check whether the inner pipe enters the water, if the water enters, pinch the tube blank that has just exited the mold to seal the inner cavity; reduce the temperature inside the mold; clean and polish the mold;

  4. A jitter ring appears inside the pipe

  Customize the api pipe production line to adjust the water output of the sizing sleeve to make the water uniform; adjust the vacuum degree of the second chamber so that the vacuum degree of the rear chamber is slightly higher than that of the front chamber; check whether the vacuum gasket is too tight; check whether there is jitter in the tractor ; Check whether the main machine discharges evenly.
