Metal spiral wound gasket installation specification:
1. The winding portion of the gasket must be interposed between the flange sealing surfaces, and the width of the winding portion cannot be arbitrarily widened. This will inevitably affect the pressing force of the bolt and thus affect the sealing performance of the gasket.
2. The basic type of gasket is best not to be used on the concave-convex surface flange. This is because the basic type gasket is under the action of the flange axial compression force, and the inner ring solder joint of the gasket is easy to open, resulting in the failure of the gasket.
3. In the harsh working conditions of high temperature, deep cold or frequent alternating heat and cold, high vibration, strong corrosive media, gaskets for flat flanges and convex flanges are best equipped with inner rings of reasonable materials.
4. Never use low-material gaskets instead of high-material gaskets. Avoid gasket failure due to material corrosion, abrasion, or other causes.
5. It is forbidden to use two or more gaskets at the same time, to avoid sealing failure between the gaskets caused by cold heat and pressure alternating.
6. When installing the gasket, the flange sealing surface should be cleaned. The surface of the gasket should not have radial scratches and other defects, and it must not be biased. The gasket on both sides of the high temperature pipeline is coated with anti-seizure agent.
7. The flanges, valves, bolts, and gaskets must be suitable during use. The pressure level must be high or low.
