Eccentric reducer rubber expansion joint carbon steel flange end EPDM rubber expansion joint

Product Introduction

Eccentric reducer rubber joint is a kind of connecting element used to connect two pipelines of different diameters, which is mainly used in water supply, drainage, circulating water, HVAC, fire protection, papermaking, pharmaceutical, petrochemical, shipbuilding, water pump, compressor, fan and other pipeline systems. Its unique design can solve the problem of misalignment and different diameters when connecting metal pipes, and at the same time has the function of shock absorption and noise reduction, which can save pipeline installation parts and reduce costs.

Features

1. Shock absorption and noise reduction
The eccentric reducer rubber joint is made of elastomer material, which can effectively absorb the vibration and noise caused by the thermal expansion and contraction, medium flow and other factors of the pipeline, and improve the operation stability of the pipeline system and the comfort of the working environment.
2. Pressure and corrosion resistance
The joint is made of high-strength, corrosion-resistant materials that can withstand high working pressures and media corrosion, ensuring long-term stable operation. The inner and outer rubber layers have excellent corrosion resistance and are able to resist chemical and water erosion, extending the service life.
3. Easy to install
The structural design of the eccentric reducer rubber fitting makes the installation process quick and easy, without the need for special installation tools or techniques. Its unique structure helps to reduce friction and jamming during installation, reducing labor and time costs.
4. Long life
Due to the use of high-quality rubber materials and unique structural design, eccentric reducer rubber joints have a long service life. Under normal working conditions, it can work stably for a long time, reducing the frequency of replacement and maintenance.

Product parameters

Use and installation of the product

1. During the construction process, the reducer rubber joint pipeline must be in a natural state, and there shall be no artificial deformation during installation. When the pipeline medium is resistant to acid and alkali, oil, high temperature and other special materials, it is advisable to choose a joint with a grade higher than the working pressure of the pipeline.
2. The normal applicable medium for eccentric rubber joints of different diameters is ordinary water at a temperature of 0-60 °C. For special media such as oil, acid and alkali, high temperature and other corrosive and hard media, the corresponding special corrosion-resistant materials should be selected, and the rubber joints can not be blind or universal.
3. When the displacement of the pipeline is greater than or equal to the maximum compensation amount of the joint, the number of joints should be increased to make the displacement parallel. It is strictly forbidden to adjust the tolerance of the pipe so that the joint is in a state of extreme deflection displacement and deviation, and it is not allowed to exceed the limit (expansion, displacement, deflection, etc.)

4. For high-rise water supply or suspended water supply, the pipeline should be fixed on the hanger, bracket or anchor frame, and the joint should not bear the weight and axial force of the pipeline itself, otherwise the joint should be equipped with an anti-detachment device (its bearing capacity must be greater than the axial force of the pipeline).
5. When installing eccentric rubber joints of different diameters, the screw rod of the bolt should extend out of the outside of the joint, and the bolts on the end face of each flange should be tightened evenly with diagonal pressure repeatedly to prevent bias. Threaded fittings should be tightened evenly using a standard wrench. Do not force the live joint to slide, slide or break off with a force. It should be inspected regularly to avoid loosening and causing water to fall off or seepage.
6. When using or storing eccentric reducing rubber joints, high temperature, ozonated oil and acid-alkali environment should be avoided. Outdoor use or sunny and windward pipes should be built with sunshades, and sun, rain and wind blowing are strictly prohibited. It is strictly forbidden to paint or wrap insulation materials on the joint surface. Due to the aging problem of rubber products, they should be checked and replaced in time.
