![Expansion Joint "EP Joint" [S Flex]](https://image.mono.ipros.com/public/product/image/ffd/2000404389/IPROS4194100441755535280.jpg?w=280&h=280)
Cylindrical type! Absorbs vibrations, noise, expansion, and displacement in piping systems! Active in air conditioning equipment, water supply and drainage sanitary equipment, and various plant facilities!
Expansion joints (flexible joints/rubber joints) are used to prevent vibrations and noise generated from piping systems, absorb expansion and displacement due to temperature and pressure changes, and mitigate or prevent the effects of various dimensional changes during installation, as well as impacts from 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, new products have been added to meet customer needs, including the high-pressure P type integrated with PTFE and the F type. Today, they are used by a wide range of customers across various industries, from household drinking water to chemical plant piping. 【Features】 1. Capable of accommodating large eccentricities 2. Excellent for installation work due to the use of loose flanges *Nominal diameters 20A to 40A are compliant with Ministry of Land, Infrastructure, Transport and Tourism specifications. For more details, please contact us or refer to the catalog.
