Which one is better to use, KXT rubber joint or corrugated compensator
KXT rubber joints and corrugated compensators are both pipeline fittings, both of which are corrosion and high pressure resistant, and are similar in use, but which product is good to use in the end?
 
KXT rubber joints are corrosion-resistant and high-pressure resistant. Rubber joints are usually used in a wide range of applications, such as water pump mouths in the drainage industry and circulating water pipeline connections in the chemical and environmental protection industry. Rubber joints can not only pass various media, its biggest advantage is that it has particularly good performance in pressure resistance and noise reduction. And it also replaces the function of compensator to compensate the displacement deviation. As the sphere of the compensator is made of rubber, it has the characteristics of high pressure resistance, good elasticity, large deflection displacement and aging resistance. Good vibration damping and noise reduction function. The service life of rubber soft joints is also 3-5 years, and there is usually no trouble with after-sales service.
 
The advantage of corrugated compensator is that it can carry various corrosive media and can withstand high air pressure. The compensator can also be used to compensate lateral displacement or combined axial and lateral displacement with a service life of 1-2 years. However, the material cost of compensator is higher. And the price of rubber joints will save a lot compared with the compensator.
