Flexible Single Ball Rubber Joint
Flexible single ball rubber joint is a kind of pipeline connecting element which is composed of rubber parts and parallel live joints, loose set metal flanges or threaded pipe flanges. With good elastic deformation ability, it can reduce vibration and noise, and solve the problems of pipe warp offset, thermal expansion and contraction.
Overview
Features
Small size and light weight: easy to install and maintain.
Good elasticity: able to absorb lateral, axial and angular displacements of pipelines.
High pressure resistance: able to work stably under high pressure environment.
Corrosion resistance: applicable to various media, such as acid, alkali, oil and so on.
Vibration and noise reduction: can effectively reduce the vibration and noise of piping system.
Easy to install: easy to install and maintain, saving time and cost.
Application Fields
Vibrating pipeline: It is suitable for pipelines with large vibration and frequent transformation of hot and cold alternation, such as chemical plants, engineering buildings, water supply and drainage pipelines.
Water supply and drainage: used in water supply and drainage, circulating water, HVAC, fire fighting and other piping systems.
Chemical industry: It is suitable for chemical substance pipeline transportation in chemical industry, cooling and dilution in petrochemical industry, etc.
Other industries: also applicable to metallurgical industry, condensate, papermaking, pharmaceuticals, ships, pumps, compressors, fans and other piping systems.
