Overview
Elastic joints protect the piping from extension, compression, misalignments and bending.Suitable for reducing vibrations and noise absorption, allowing the further reduction of the effects of water hammers.
for water plants, pumping stations, conditioning and heating, industrial and agricultural applications, compressed air circuits.
Features
1, Versatile hand-built construction. Made in China
2, Absorbs directional movement
3, Absorbs vibration, noise and shock
4, Compensates for expansion
5, Wide flowing arch design
6, Virtually eliminates sediment buildup
7, Economical fully molded construction
8, High vacuum rating (up to 30" Hg) can be supplied for certain sizes
9, Special grooved flange ring design, prevent rubber end pulling out
10, Solid galvanized steel floating flanges speed the installation time
11, High tensile aircraft cable is embedded in the raised face rubber ends to prevent pull out and avoids the sharp cutting edge of solid steel rings
12, No gaskets required; integrally rubber flanged design, no gaskets required, DIN PN10/16 drilling standard, other flange drilling available, including ANSI 150lb/300 lb, BS, and JIS
