Rubber Flexbile Joints
1) Product Performance
LIWEI Rubber Flexbile Joints are designed for piping systems to absorb pipe movements, relieve stress, reduce system noise/vibration, compensate for misalignment/offset and to protect rotating mechanical equipment against start-up surge forces.
Rubber Flexbile Joints is a single sphere design with less length, the supply range is from 32mm to 3600mm, and design pressure can be 1.0MPa/1.6MPa/2.5MPa, which is always used where low cost or space limitation control.
2) Application Range
Equipped with the excellent comprehensive performances of flexible rubber joint, LIWEI Rubber Flexbile Joints can be used for lift and transportation of raw water and sewage, 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. LIWEI Rubber Flexbile Joints is also suitable to transport all grain and powder material and gas for its high abrasive resistance.
In addition, special notifications are hereby conducted for design units and clients so as to ensure the project quality. Please note to install anti-break stop device, if LIWEI Rubber Flexbile Joints are designed to install close to pump exit nozzle and pipes' corner. If your pipes need to be buried, please use our patent-buried protective devices. In a word, remark requirement for use, and we will provide satisfactory service to you.
