DN35~5000mm single-ball flanged rubber coupling feature rugged yet flexible polyester cord fabric reinforcement, to ensures an exceptional burst pressure rating.
The streamlined flowing arch design reduces turbulence and allows smooth, quiet flow-no need to fill the arch and restrict its movement.
1. Benefits
Flowing arch design prevents sediment buildup and reduces turbulence. Floating flanges can be rotated to accommodate torsion misalignment. Molded spherical bellows accommodate up to one inch of axial movement and transverse deflection polyester-reinforced nitrile tube earns high pressure rating without sacrificing flexibility; Resists most hydrocarbons, oils and gasoline
2. Application Scope
Due to the sound complex performance of the rubber compensators, it is mainly used for the lift and transport of raw water and sewage, and pipeline transportation of feed-water and water for cooling circulation in thermal power plants, condensed water in metallurgy and chemical substances in chemical industry as well as dilution and flexible connection between short and long pipelines. Relying on the high abrasion resistance of rubber, it is also suitable for the transportation under low temperature of powdery and grainy air in any industry.
