Pipe Flange Gaskets

Guarnizioni in gomma per flange di tubi in EPDM

EPDM pipe flange rubber gaskets are used for improved joint performance. They are considered much more superior to conventional ring or full-face gaskets. Although pipe flange gaskets are usually used for all normal water and sewer services, they are especially useful in demanding services like very large-diameter flanged piping. For specially designed long-span installations, involving 2 or 3 or more lengths of pipe or with any underground flanges, flange gaskets are of great help because they could be subjected to undesirable beam loading.

Guarnizioni per tubi in EPDM

EPDM is a very durable synthetic rubber with excellent weather resistance, ozone resistance and heat resistance. Therefore, EPDM Pipe Gaskets are often used in pipeline systems in different environments such as outdoor, overhead and buried to ensure good sealing performance and long service life.

Rubber pipe gasket is a common sealing element used between pipe flanges to prevent liquid or gas leakage. Rubber gaskets are usually made of rubber materials and have good elasticity, corrosion resistance and wear resistance.

 

One of the main characteristics of rubber gaskets is their plasticity and deformability, allowing them to fill the gaps between flanges and provide an effective seal. Rubber materials have high elasticity, can adapt to different pressure and temperature changes, and provide reliable sealing performance.

 

Rubber gaskets also have good corrosion resistance and can resist erosion by a variety of chemicals, including acids, alkalis, and solvents. This makes rubber gaskets a widely used sealing material in various industrial fields.

 

In addition, rubber gaskets also have good wear resistance and can be used for a long time under friction and pressure conditions without being easily damaged. This allows the rubber gasket to effectively withstand pressure and friction and maintain its sealing performance in pipe systems with high flow rates and high pressures.

 

Rubber pipe gasket selection should be determined based on specific application needs and work environment. Different rubber materials have different properties. For example, nitrile rubber (NBR) has better oil resistance, chloroprene rubber (CR) has better corrosion resistance, and polyurethane rubber (PU) has better wear resistance. . Therefore, when selecting a rubber gasket, factors such as the nature of the liquid or gas medium, temperature range, pressure requirements, and the influence of chemical substances need to be considered.

 

In summary, rubber pipe gaskets are made of rubber material and have good elasticity, corrosion resistance and wear resistance. They are commonly used sealing elements in pipeline systems, which can effectively prevent leaks and ensure the safe operation of the system.
