ADVANTAGE OF USING SONA RUBBER EXPANSION JOINTS
1.ABSORBS VIBRATION , NOISE AND SHOCK
Sound, travelling axially through SONA Joins, is stopped at once. Water hammer, pumping impulses and water born noises are absorbed by the molded light-weight thin-wall structure.
2.EASY TO INSTALL, EASY TO REMOVE
Loose flanges, no need of gasket or packing, and elastic spherical body make the joint easy to install or remove.
3.SECURITY ASSURED IN USAGE
Special spherical carcass endables its body, when subjected to high pressure and expansion, not contacting with the connecting bolt head. Thus, the joint may be used in a sense of damage proof and full security.
4.HIGHER BURST STRENGTH
Spherical shape is stronger than cylindrical shape or other configuration. Thus under pressure,SONA Joint is 4 times as strong as a cylindrical joint. Additionally, our products are made of best suitable material,and hence their burst pressure is much higher than those of other makes.
5.SUITABLE FOR SUCTION AND DELIVERY
Owning to its excellent molding technique with its tough chemical fiber, SONA Joint can satisfactorily withstand the suction and discharge. Vacuum rating can stand up to 750mm Hg.
6.HIGH EFFICIENCY
SONA Joints has streamlined, flowing arch to reduce turbulence, sediment build-up, thrust area and the effects of thrust on the piping system equipment.
7.LOW DEFORMATION UNDER PRESSURE
Internal pressure is exerted in all directions distributing forces evenly over a large area. Hence, the deformation of SONA Joint due to pressure is much lower than that of other makers.
8.LIGHT AND COMPACT
The space required for the installation of SONA Joint is about half of the requirement of cylindrical .
9.GREATER MOVEMENTS ARE AVAILABLE
Axial compression and elongation, deflection and angular movements will be greater.
10.WIDE SERVICE RANGE
Made with chemical resistant elastomers such as Neoprene, Nitrile, Hypalong. EPDM：insures a product compatible with the fluid being pumped or piped. Operate up to 16KG and -20°C to 100°C.
