Inner ring metal spiral wound gasket is suitable for the sealing of which flange surface?
product description:
The inner ring metal spiral wound gasket (mifso-240 type) is composed of a basic metal spiral wound gasket and an inner and outer ring made of steel plate. The inner ring is used to strengthen the pressure and prevent the winding from loosening. Different materials are available for the inner ring. Metal spiral wound gaskets are divided into four forms: basic metal spiral wound gaskets, metal spiral wound gaskets with inner rings, metal spiral wound gaskets with outer rings, and metal spiral wound gaskets with inner and outer rings.
Metal spiral wound gaskets are the most resilient gaskets in semi-metallic gaskets. The structural density of metal spiral wound gaskets can be made according to different locking force requirements, and the inner and outer steel rings are used to control the maximum compression degree. The surface accuracy of the flange sealing surface in contact with the gasket is not high. Metal spiral wound gaskets are especially suitable for occasions where the load is uneven, the joint force is easy to relax, the temperature and pressure change periodically, and there is impact or vibration. Spiral wound gasket is a static sealing original for flange connection processing such as valves, pumps, heat exchangers, towers, manholes, hand holes, etc.
Inner ring metal spiral wound gasket is suitable for the sealing of which flange surface?
characteristic
1. Wide range of applicable working conditions. Can withstand high temperature, high pressure and adapt to ultra-low temperature or vacuum conditions. By changing the material combination of the gasket, the chemical corrosion of the gasket by various media can be solved.
2. Strong stress compensation ability. In the working position with frequent temperature and pressure fluctuations, the sealing performance is stable and reliable.
3. Excellent sealing performance.
4. The surface accuracy requirements for the flange sealing in contact with the gasket are not high.
5. Easy installation and low gasket preload pressure

The basic introduction of metal spiral wound gasket!
For different types of seals, the principle of action is different. Static seals rely on closing the gap between the joint surfaces to achieve sealing; while dynamic seals cannot simply rely on the gap between the closed joint surfaces to achieve sealing, because the tighter the gap, the greater the frictional resistance when the dual surfaces move relative to each other, resulting in joint The surface heats up, which makes the seal fail quickly. Therefore, the main point of the dynamic sealing principle is to Exhaust Muffler Gasket factory maintain the seal without generating large frictional resistance, including reducing the pressure difference on both sides of the seal and maintaining a fluid lubricating film between the joint surfaces.​​
The basic requirements for seals are as follows:
1. It has good sealing performance within a certain pressure and temperature range.
2. The friction resistance is small and the friction coefficient is stable.
3. The wear is small, the wear can be automatically compensated to a certain extent, and the working life is long.
4. Compatible with the working medium.
5. Simple structure, convenient assembly and disassembly, and low price.
