Product Description

Flexible Double Sphere Rubber Joint, also known as flexible rubber joints, flexible rubber joints, soft rubber joints, shock absorber, (shock absorbers throat), rubber shock absorbers, rubber expansion joints and so on. The product consists of inner and outer layers of plastic, ply and bead composition tubular rubber parts, high temperature, high pressure molding after curing with metal flanges or parallel connector loose jacket combination. This product utilizes the high elasticity of rubber, high gas resistance, chemical resistance, weatherability and resistance to radiation and other advantages to reduce vibration and noise, and thermal expansion and contraction due to temperature changes from the compensation due to the widely used various piping systems.

Connection: Generally loose flange type (semi-hermetic), fixed flange (sealed), clamp and threaded connections.

Soft rubber joints Material:

Soft rubber joints ball is from the inside layer, scraping gum enhanced multi-layer nylon (nylon) cord fabric, rubber outer layer composite tubes. Depending on the medium used rubber material is also different, there are natural rubber, styrene-butadiene rubber, butyl rubber, nitrile rubber, EPDM rubber, neoprene, silicone rubber, fluorine rubber and so on. Respectively, with heat, acid, alkali, corrosion resistance, abrasion resistance, oil and other functions.

Product performance:

1,Flexible Double sphere rubber joint has good elasticity and long service life, especially for some installation environment is harsh environment have a good ability to adapt.
2, installed on the pipeline can be achieved for pipeline axial, lateral and angular displacement compensation, guarantee the pipeline safe operation, so as to prolong the service life of pipelines.
3, good vibration reduction noise reduction function, greatly optimize the running environment of the pipe lines.

Product use:

Because F lexible Double sphere rubber joint has good comprehensive performance, so it is widely used in chemical industry, building, water supply, water drainage, oil, light and heavy industry, frozen, sanitary, plumbing, fire protection, electric power and other basic engineering, shakes the pipes of larger pipe, cold heat changes frequently.

Main date:

Notes: 1. For OEM orders with special requirement, rubber joints can be made according to customers' drawings. Generally, flange standard is GB/T9115.1-2000, other GB, JB, HG, CB, ANSI, DIN, BSEN, NF, EN, JIS, ISO flanges are also available upon request. Material of rubber body can be NR natural rubber, EPDM, Neoprene, IIR butyl rubber, NBR Buna-N, FKM, etc.
2.When rubber joints size above DN200 are used for overhead water supply system, the pipes must be equipped with fixed supports or fixed brackets, otherwise control units shall be installed on rubber joints.
3.Matching flanges of rubber joints shall be valve flanges or GB/T9115.1(RF) flanges.

Installation instructions:

1, when installation to protect the ball at the ends of the rubber sealing surface, and the media do not meet the requirements of the product is strictly prohibited. Please refer to additional product installation manual carefully before install and use, to avoid some unnecessary loss.
2, rated working pressure of the rubber joint working pressure than it actually is a gear, to ensure the safe operation of the pipeline can.
3, pipe must have a fixed support or fixed bracket, the force must be greater than the axial force of fixed bracket. When installed vertically and aerial product should be installed on both ends of the corresponding fixed bracket and mechanical support, in order to prevent pulled off after work under pressure.
4, rubber joint in the process of flange connection, according to diagonal uniform pressure way for installation, it can avoid uneven force, cause the late of pipeline leakage.
5, rubber joint during the installation process must avoid beyond their displacement to compensate the pipeline vibration and heat bilges cold shrink. By adding spacing device or increase the quantity of rubber joint, divide the work pressure is the right choice.
