Combination Bonded Washer is a composite gasket made of metal and non-metal materials. Its structural forms are divided into three types: metal-non-metal, non-metal-non-metal, and metal-non-metal-metal. Combination gaskets are widely used in various types of machinery manufacturing, including automobiles, metallurgy, petroleum, chemicals, rail transportation, aviation, aerospace and other industries. It is suitable for various working media, including liquids, gases and solids.
Combination Bonded Washer is generally made of rubber rings and metal rings bonded and vulcanized as a whole. It is a sealing ring used to seal threads and flange connections. It has two sizes, metric and imperial. Once damaged, it often leaves a big hidden danger to the sealing part and may cause leakage. Therefore, it is very important to choose the right size of gasket. In production, the metal ring of the combination gasket is generally not easy to damage, and the rubber ring will be checked and replaced regularly. Be sure to choose the right size of rubber ring, and don't be lucky enough to choose a slightly smaller or larger rubber ring.
The metal gasket in the Combination Bonded Washer ensures that the components are reliably connected and securely fixed. The thickness of the retaining ring limits the compression of the elastomer seal and eliminates the phenomenon of exceeding the limited torque at the joint, thus ensuring the reliability of the sealing system. It is generally used with a ferrule-type pipe joint. To prevent leakage of oil, fuel, water and medicine, the metal ring will be rust-proofed, and the rubber ring is generally made of oil-resistant nitrile rubber or fluororubber. Due to its simple structure, efficient sealing and low price, it is widely used in the machinery manufacturing industry.
In the process of replacing the Combination Bonded Washer, special attention should be paid to the following matters. First, the seal should not be installed forcibly. Some seals need to be placed in the groove. At this time, they need to be installed tightly. Be careful and slowly install them during operation. Do not force them with brute force or large movements, otherwise the seal will be damaged and will not play the sealing role it should. When using a combination gasket for sealing, you should pay attention to cleaning the sealing surface and the combination gasket in advance and evenly apply the seal.
During installation, balance and symmetry should be maintained, and the seal should be placed parallel to the effective sealing surface. After installation, further observation is required. If leakage is found, reinstall it in time to avoid leakage during production and production interruption. Third, do not damage the sealing surface or sealing line of the rubber ring. The sealing performance of the flat seal depends on the upper and lower end faces. If damage occurs, it will cause leakage. The rubber ring is made of soft and elastic rubber, plastic, fiber and other special materials. Therefore, during transportation, installation and maintenance, the surface of the combination gasket should be smooth and not damaged or deformed. Attention should be paid to scratches, abrasions, bumps, etc.
Since the Combination Bonded Washer is composed of different material layers through composite processing, it is necessary to ensure the reasonable control of the bonding strength and clamping force between different material layers, and the manufacturing difficulty is great. Compared with traditional single-material gaskets, the material cost and production cost of the combination gasket will increase. When selecting a combination gasket, the appropriate combination gasket model and material should be selected according to the specific working conditions.
It is worth mentioning that the combination gasket is suitable for various working media, including gas. Gas is a very special medium, but it does not affect the use effect of the combination gasket.
Combination Bonded Washer is a new type of material that is increasingly being used, and its advantages are obvious. During use, attention should be paid to the selection and use methods to better bring out its characteristics.
