1.Our products have the following performance:

LIWEI GJQ (X) -SQ-II flexible rubber joints is a three-sphere end face sealed rubber joints with flange connection,which is made up of the composite rubber ball. The diameter conventional specifications of GJQ (X) -SQ-II rubber joint is from DN300 to DN3000.And the ranging in length is between 450mm to 650mm. The maximum elongation displacement is 120mm, maximum compressive displacement is135mm, maximum radial displacement is 90mm, and maximum deflection displacement is within plus or minus 10 degrees. Flange material is Q235.The national standard flange is manufactured in accordance with GB / T 9119-2010. The optional inner layer and an outer layer of rubber categories include: Butyl rubber IIR, neoprene CR, EPDM rubber EPDM, natural rubber, NR, NBR rubber NBR.

Good select materials, advanced equipment, skillful workmanship, rigorous quality control standards, attractive design and durability. They are well-known for excellent quality, most competitive price, and lower cost and prompt delivery.

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.

3.Characteristic:

1)This product could primarily reduce the vibration and the noise of the piping system, completely solve the different piping problems as displace of joint, axial flex and etc.

2)According to different material requirement, product could be made as acid proof, corrosion proof to suit different medium and environments.

3)The materials are 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 of the rubber body.

4)For flanges of other standards or non-standards. It is necessary to be agreed upon separately. Please specify standard of furnish diagram and relative parameter. We will manufacture accordingly. Rubber material may be selected according t your requirement.

5) Anti-corrosion: EPDM and NBR rubber can bear high temperature and can anti-corrosion.

6) Double sphere flange end rubber joint: The rubber body has two bridges. It can bear more pressure and the length is long than single sphere rubber joint.

7) The size can made as customer's drawing, we can make mould for special type.

8) They are cost effective, the total cost is low because of rubber is cheap and it have long use life.
