How to choose and install spiral wound gaskets?

In the modern industry,as long as we carefully observe, we will find an unremarkable thing, playing an important role in the industry, that is, spiral wound gasket. In the industry, it is probably because of such a small metal-wound gasket that causes a big accident. For example, in the petrochemical industry, once there is a problem with the spiral wound gasket, it will affect the environmental problem of the whole ocean, or the same in the shipbuilding industry. If there is a problem with the spiral wound gasket, it may lead to the whole boat. The safety of the ship. So a small metal-wound gasket is inconspicuous in the device and can’t even be seen, but it is really crucial.(Spiral wound gaskets installing and purchased)

In fact, spiral wound gaskets have been used in many industries, such as pipes, pressure vessels, lifting equipment, etc. in the machinery industry, as well as many municipal engineering and community fire protection. Of course, the most used ones are the mechanical industry. Most of the equipments use metal-wound gaskets. Of course, there are still very few parts that are not used. For example, some equipments require frequent maintenance and often choose to save metal-wound gaskets. this part. In fact, in the industry regulations, all flanges are required to be in direct contact with each other. Metal-wound gaskets must be used. Metal-wound gaskets not only play a buffering role, but also play a good sealing role. For example, if the flanges are in direct contact with each other in the pressure vessel, they will become steel-to-steel contact. There will be gaps in the middle, and air leaks. The sealing performance of the metal-wound gasket can prevent steam.

How to choose and install spiral wound gaskets?

  • Select the gasket according to the working conditions of the spiral wound gasket and the flange sealing surface type.
  • For the gaskets of the production enterprises that are sound and effective in the quality management system, it is best to use the metal-wound gaskets of the enterprises with valid type test reports.
  • The surface of the spiral wound gasket main body is not allowed to have flaws, voids, irregularities and rust spots that affect the sealing performance.
  • Compression ratio, rebound rate and sealing performance are important performance indicators of the gasket. Generally speaking, under the premise of meeting the compression ratio requirements, the higher the rebound rate, the better; and meet the requirements of the rebound rate standard. Under the premise, the test value of the compression ratio is also larger. spiral wound gaskets with good sealing performance, moderate compression ratio and maximum resilience should be selected.
