The metal spiral wound gasket is a material or a part that prevents fluid or solid particles from leaking between adjacent joint surfaces and prevents external impurities such as dust and moisture from invading components inside the machine equipment.
1. Check the quality of flanges, bolts, nuts, and gaskets carefully before installation. Carefully inspect the mounting condition of the flanges or connectors to see if there are any defects such as uneven, wrong, open, and misaligned holes.
2. The surface of the flange or closed part must be cleaned, and mechanical impurities must not adhere to the surface of the gasket and the bolts and threads.
3, gasket can not be installed, should ensure that the pressure balance.
4. When tightening the nut, apply a balanced force. The bolt must be symmetrically divided into 2 to 3 tightenings to balance the gasket.
Precautions when installing metal wraps
Metal spiral wound gasket has good compression and rebound resilience, especially with expanded graphite belt as filling material, sealing performance is good, under normal operating conditions, various media should be used. It is especially suitable for static sealing elements in the joints of the low pressure pipe flanges, equipment flanges, valves, pumps and pressure vessels under conditions of relaxation, temperature fluctuations, pressure fluctuations, stamping and vibration. Metal spiral wound gaskets are widely used in petrochemical, machinery, power, metallurgy, shipbuilding, pharmaceutical, atomic energy and aerospace sectors, and have strong stress compensation capabilities. In the work stations where the temperature and pressure fluctuate frequently, the sealing performance is stable and reliable.
