How to choose a wound gasket?

点击量: 4 Release time: 2018-05-23 Clicks: 4

Winding gasket is an important sealing element. Metal winding gasket is widely used in petroleum, chemical, metallurgy, power generation, shipbuilding and other industries. It is the key to the static sealing of pressure pipes, valves, pumps, heat exchangers and other equipment Parts. Therefore, the selection and use of high-quality wound gasket products is of great significance to reduce and eliminate running, dripping, dripping and leakage, to ensure the safety of the host equipment and the normal operation of the pressure pipeline.

Points to note when choosing a wound gasket product:

1. Select the gasket according to the working conditions and flange sealing surface type.

2. Select the products of production enterprises with sound and effective quality management systems, and it is best to select the products of enterprises holding special equipment (pressure pipeline components) manufacturing licenses and valid type test reports.

3. The surface of the main body of the sealing gasket is not allowed to have flaws, voids, unevenness and rust spots that affect the sealing performance. The non-metallic band on the surface of the gasket body should be evenly and appropriately higher than the metal band. The interlayer texture should be clear, but the metal band should not be exposed. The distance between the solder joints of the metal wound gasket should be uniform, and there should be no defects such as non-fusion or over-melting. The surface of the reinforcing ring should be free of defects such as burrs, unevenness, and rust spots. The distance between the upper and lower sealing surfaces of the gasket body and the upper and lower surfaces of the reinforcing ring should be equal. The ring and the gasket body should be positioned and loosened appropriately.

4. Compression rate, rebound rate and sealing performance are important performance indicators of gaskets. Generally speaking, under the premise of meeting the compression rate requirements, the higher the rebound rate, the better; Under the premise, the test value of the compression ratio is also better. Products with good sealing performance, moderate compression rate and the highest rebound rate should be selected.
