steel solid Ovalring gasket
The metal oval gasket is a gasket made of metal materials through forging, heat treatment and machining, and its cross-section shape is oval. This gasket has a radial self-tightening sealing effect, relying on the gasket to contact and press the inner and outer sides of the flange trapezoidal groove to form a seal. The metal oval gasket originated from the United States and was first used in the boiler field in the 1920s. It was then widely used in the oil production and refining industry. As the temperature and pressure of steam power plants increase, the use of metal oval gaskets is becoming more and more extensive.
The main performance parameters of the metal elliptical gasket include:
Gasket coefficient (m): 5.50-6.50
Using pressure: ≤42 MPa
Using temperature: -196ºC to 1000ºC
Minimum preload pressure (y): 126.6-182.8 MPa
In terms of dimensional limit deviation, the pitch diameter (P) of the ring gasket is ±0.18 mm, the width (A) is ±0.20 mm, the height (H) is ±0.4 mm, the bottom width (C) of the octagonal ring gasket is ±0.2 mm, the angle is 23°±0.5°, and the fillet radius (R) of the ring gasket is ±0.4 mm. If the height difference between any two points of the ring gasket does not exceed 0.4 mm, the limit deviation of the ring gasket height (H) can be +1.2 mm.
The metal oval gasket has the following performance characteristics:
High temperature and high pressure resistance: suitable for high pressure flanges
Durable and reliable sealing
Adaptable to working conditions with variable loads
Corrosion resistance: The low hardness metal ring gasket adopts customized low carbon content metal materials, adjusts the trace elements, and changes the ordinary heat treatment method to ensure the realization of the low hardness metal ring gasket.
The application range of metal oval gaskets is very wide, mainly including:
High temperature and high pressure pipelines (such as steam and oil industry, petrochemical industry)
Towers, tanks, heat exchangers, pipelines and other machine joints
High-speed joints, high temperature and high pressure valve covers
Wellhead devices and seals on Christmas trees in the oil and gas industry.
Due to its excellent high temperature resistance, high pressure resistance and corrosion resistance, metal oval gaskets are widely used in many industries such as petrochemical industry, shipbuilding industry, food industry, aerospace industry and automobile industry.
