2. The sealing cost of the material shrinking rotary joint is higher than that of the ordinary joint. Some manufacturers reduce the material material standard in order to save costs. The high temperature and high pressure resistance of the sealing component are also reduced, which is likely to fail in the high temperature and high pressure environment. Give way.
3. Housing material When we manufacture rotary joints, we use a stainless steel shell, which has good corrosion resistance and thermal conductivity, which can reduce the temperature rise of the sealed components inside the rotary joint and prolong the service life.
