Flexible rubber couplings for pipes is a mechanical component used to connect two shafts or equipment in a pipeline system, using the elastic properties of rubber to compensate for pipeline displacement, absorb vibration and reduce noise. It is widely used in pipeline systems in water supply and drainage, chemical industry, metallurgy, HVAC and other industries, especially in scenarios where vibration buffering, installation error compensation or thermal expansion and contraction of pipelines are required.
flexible rubber couplings for pipes Detail
| Product Name | Flexible rubber couplings for pipes |
| Product Material | The core material of the pipeline flexible rubber coupling is rubber elastomer, common types include natural rubber (NR), nitrile rubber (NBR), ethylene propylene diene monomer rubber (EPDM) and fluororubber (FKM). |
| Product Process | Precision machining: First, mix the rubber raw materials and vulcanizer in proportion and mix them in an internal mixer. Cut them into appropriate sizes and place the pre-treated metal flange. Then, use a flat vulcanizer at a temperature of 140-180℃ and a pressure of 10-20MPa to firmly bond the rubber and the metal flange. |
| Surface Treatment | Options include galvanizing, painting, spraying, chrome plating, passivation and hot dip galvanizing. |
| Customizable Products | Gears / Sprockets / Worms / Shafts / Rack Bars / Bevel Gears, etc. |
Product Advantages

What is a flexible rubber couplings for pipes?
Rubber Flexible Coupling for Pipes is a component used in pipeline systems to connect pipelines or equipment through rubber elasticity to achieve displacement compensation, vibration reduction, noise reduction, and sealed connection. The following is an introduction from key dimensions:
What is the main purpose of flexible rubber couplings for pipes?
Pipeline flexible rubber couplings have multiple functions of "elastic compensation + vibration and noise reduction + sealing and anti-corrosion", becoming the core component for solving displacement, vibration, noise and other problems in pipeline systems. Its selection needs to be combined with parameters such as medium characteristics, working pressure, temperature, displacement, etc. to ensure that it matches the system requirements. At the same time, attention should be paid to the uniformity of bolt tightening and the natural state of the rubber body during installation to achieve the best performance.
What are the advantages of flexible rubber couplings for pipes?
Pipeline flexible rubber coupling is a key component in the pipeline system that uses rubber elasticity to achieve connection. It has significant advantages. With rubber elastomer as the core, it can flexibly compensate for the axial, radial and angular displacement of the pipeline, adapt to thermal expansion and contraction, installation errors and foundation settlement, and avoid stress cracking.
