Since it was invented in the early last century, standard spiral wound gaskets have been the most widely used gaskets. They have good compression performance and resilience performance.
At first, in order to adapt to the requirements of industrial development, in the case of fluctuating pressure and temperature load, it solved the sealing problem that other gasket types could not solve. Its V-shaped metal winding tape can ensure good resilience when the stress is released. The non-metallic packing tape ensures the airtight performance, and at the same time reduces the prestressing requirements of the gasket.
After metal
standard spiral wound gaskets were introduced into China, due to the good grade of flexible graphite in China, the graphite reserves rank first in the world. In addition to being widely used in China, the domestic metal graphite
standard spiral wound gaskets are also exported to foreign countries, and are now widely used in the international market. Most of the metal
standard spiral wound gaskets with graphite as filler material come from domestic manufacturers. Domestic manufacturers have also registered English brands to occupy the international market, like Wealson has a wide international reputation.
The reason why it is called a metal
standard spiral wound gasket is because it is a gasket wound by layers of metal tape (SS304 stainless steel tape and SS316 stainless steel tape are generally used in China) and filler.
