　　Sealed metal wrap gasketfeature

1. The applicable operating range is wide. Capable of withstanding high temperatures, high pressures, and adapting to usage conditions under ultra-low temperatures or vacuum. By changing the material combination of the gasket, the chemical corrosion problem of various media on the gasket can be solved.

2. Strong stress compensation capability. At workstations with frequent temperature and pressure fluctuations, the sealing performance is stable and reliable.

3. Excellent sealing performance.

4. The surface accuracy requirement for the flange sealing surface in contact with the gasket is not high.

5. Easy to install, with low pre tightening pressure on the gasket.

Purchase items

1. Select gaskets based on operating conditions and flange sealing surface type.

2. Select products from production enterprises with sound and effective quality management systems, and choose products from enterprises holding special equipment (pressure pipeline components) manufacturing licenses and valid type test reports.

3. Compression rate, rebound rate, and sealing performance are important performance indicators of sealing gaskets. Generally speaking, the higher the rebound rate, the better, while meeting the compression rate requirements; On the premise of meeting the rebound rate standard requirements, it is also better to have a higher compression rate test value. Products with good sealing performance, moderate compression rate, and maximum rebound rate should be selected.

4. The surface of the gasket body is not allowed to have scratches, gaps, unevenness, or rust defects that affect the sealing performance. The non-metallic strip on the surface of the gasket body should be evenly and appropriately raised above the metallic strip, and the interlayer texture should be clear, but the metallic strip should not be exposed. The spacing between the welding points of the metal wrapped gasket should be uniform, and there should be no defects such as lack of fusion or over fusion. The surface of the reinforcing ring should not have defects such as burrs, unevenness, rust spots, etc. 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 reinforcing ring and the gasket body should be tightly fixed and not loose; The outer ring and gasket body should be kept in position and can be appropriately loosened.
