Application scope of octagonal gasket
Octagonal gasket is an important metal sealing component, which can withstand extreme working conditions due to its unique octagonal cross-sectional design and is widely used in multiple industrial fields. Its main application scope includes:
Petroleum and natural gas industry: mainly used for sealing oil and gas pipelines, wellhead equipment, Christmas trees, high-pressure valves, and flange connections, which can effectively cope with high temperature and high pressure environments and frequent fluctuations in pressure and temperature.
Chemical and petrochemical industries: suitable for flange sealing of pressure vessels, towers, reactors, heat exchangers, and high-pressure pipelines, especially performing well in handling corrosive media.
In the field of energy and power, it is commonly used for sealing high-pressure steam pipelines, boilers, autoclaves, and steam power devices to ensure stable operation at high temperatures (up to 1000 ℃) and high pressures (such as 15000PSI or 150MPa).
General industrial equipment: used for sealing various high-temperature and high-pressure valves, container covers, joint surfaces, etc., such as pressure vessels, pipeline flanges, etc., suitable for working conditions with a temperature range of -196 ℃ to 1000 ℃ and a pressure range of 2.0-150MPa.
Octagonal gaskets are typically made of stainless steel (such as 304, 316L), carbon steel, or alloy steel, and comply with international standards such as API 6A and ASME B16.20. Their excellent corrosion resistance, high temperature and high pressure resistance, and wave resistance make them the preferred sealing solution for harsh working conditions
Usually used for pipe flanges, tower tanks, pressure vessels, high-speed joint surfaces, high-temperature and high-pressure valves, and covers for high-temperature and high-pressure steam, gas, and solvents. Wellhead equipment and seals on Christmas trees in the petroleum and natural gas industry
Metal ring gaskets originated in the United States and were first used in the boiler industry in the 1920s. Later, they were used for sealing manhole covers and other windows of high-pressure reactors. They were particularly valued in petroleum production and refining industries. As the temperature and pressure of steam power units increase, the use of metal ring gaskets becomes increasingly widespread
