Thread Rubber Joint For transporting powder DN50
Thread Rubber expansion Joint
Rubber Joint
Rubber expansion joint has the characteristics of good sealing, light weighting, easy to fix and maintain, also has long working expecting, but please keep far away from sharp metal in order to avoid breaking the rubber body.
Equipped with the excellent comprehensive performances of rubber expansion bellows, thread rubber bellows can be used for lift and transportation of raw water and sewarubberge, transportation of water supply, cooling cycle water of thermal power plant, condensate water of metallurgy industry and chemical materials of chemical industries, cooling and dilution of oil and chemical industries and flexible connection of other industries. It is also suitable to transport all grain and powder material and gas for its high abrasive resistance.
Due to its good integral function, flexible rubber joint is used widely in key projects of chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, health, fireproof and power, etc.
