PEX Press Fitting For Water

The PEX press fitting is a type of pipe joint that is widely used in various industries. It is a connection method that uses the compression force to achieve sealing and mechanical connection between the pipe and the fitting.

The precautions for the use of clamped pipe fittings are as follows:

1,Press and hold the clamping tool until the pressure is relieved. Insufficient clamping pressure is the main cause of leakage and degradation of joint performance.

2,After clamping, the pipe of DN15~DN50 should be tested with a hexagonal gauge. If the hexagonal gauge card does not go in, the pressure should be properly increased and the pipe clamping should be carried out until the hexagonal gauge can be successfully stuck in the test. If there is relaxation at the entrapment, you can re-entrapment at the original entrapment once.

3,For pipe fittings with threads, the threads should be tightened first and then jammed, so as not to cause the joint to loose due to screwing after the completion of clamping.

4,When the pipe bends, please correct in the straight pipe part, do not correct in the pipe part, otherwise it is likely to cause the relaxation of the trapped pressure and cause leakage.

5,For DN65~DN100 pipes, the tail of the ring die seat should not touch any object when clamping with the ring die, and ensure the spatial distance of the tail of the ring die seat when pressing the ring die.

6,Before clamping work, the pressure of the electric hydraulic pump should be adjusted, the plastic cap of the pressure regulator should be opened, the Ø8mm hex nut should be unscrewed, and the pressure should be increased in the clockwise direction with a flat-head screwdriver, and the pressure should be reduced in the counterclockwise direction until the required working pressure is adjusted.

7,When the installation pipe is crooked, calibration can not be taken at the position of the pipe fitting, once the calibration at the clamp may lead to relaxation, which is also an important factor causing poor sealing, should be carried out at the straight pipe.

8,If the pipe fittings cannot be successfully placed in the pipe, check whether the raw edges of the pipe fittings have been thoroughly cleaned, especially the raw edges of the inner and outer walls, because the raw edges will harm the gap connection between the pipe fittings and the pipe.

9,When the stainless steel quick fitting joint is greasy, be sure to insert it clean. Especially at the end of the pipe and the rubber seal of the quick fitting joint, determine whether there is foreign matter, if there is foreign matter, immediately solve, so as not to cause more serious problems.

10,Clamp pipe fittings are thin-walled stainless steel to be handled lightly, can not be thrown, and can not be trampled during construction.

11,When stained with oil, it is necessary to scrub. In particular, the pipe end and pipe fittings EPDM sealing ring parts, determine whether there is residue, if there is residue to remove immediately to prevent affecting its sealing.

12,If the pipeline is installed around the bay or in a site with high salinity, anti-corrosion countermeasures should be considered.

13,When the pipeline system is suitable for other media other than water (such as oil, chemical agents, etc.), please communicate with the business to avoid the sealing ring of the pipe fitting can be damaged by media corrosion and expansion.

The above information is for reference only, and specific precautions may vary according to different application scenarios and materials.
