Pressure type! Absorbs vibrations, noise, expansion, and displacement in piping systems! Active in absorbing expansion and displacement in factory equipment piping and water supply and drainage piping!
Expansion joints (rubber joints) are used to prevent vibrations and noise generated from piping systems, absorb expansion and displacement due to temperature and pressure changes, as well as to accommodate various dimensional fluctuations during construction and mitigate or prevent the effects of earthquakes and ground subsidence. They are considered essential components in piping installations. The E-P joint was launched in 1970 (Showa 45) as a low-pressure R type for elevated water tanks, and since then, it has added new products to meet customer needs, including the integrated high-pressure P type PTFE F type. Today, it is used by a wide range of customers in various industries, from household drinking water to chemical plant piping. 【Features】 1. Has a larger allowable displacement than the P type. 2. Stability in durability due to the combination of strong reinforcing fibers and reinforcing steel wires. 3. Uses EPDM for the inner and outer rubber, offering excellent chemical resistance and weather resistance. 4. Excellent for installation work due to the use of loose flanges.
