Our Metal Jacketed Gaskets Manufacturers provide high-quality Spiral Wound Gaskets of various types and specifications.
The sealing element of the spiral wound gasket is composed of a V-shaped metal strip spirally wound with a soft sealing packing. The metal strip has excellent resilience, and the flexible sealing packing ensures excellent sealing. Due to this combination of materials, spiral wound gaskets are suitable for sealing under conditions of temperature and pressure changes. Depending on the application, spiral wound gaskets can specify the outer ring and/or the inner ring.
Performance of spiral wound gaskets.
•Spiral wound gaskets are suitable for use in a large gasket stress range.
•Spiral wound gaskets can be used to seal fluid pressures up to 400 bar and can withstand low temperatures up to 1000 degrees Celsius.
•Spiral wound gaskets are strong and easy to install.
• The external guide ring simplifies assembly and prevents the gasket from bursting.
•By combining different winding materials and metals, washers can be customized to suit various operating conditions.
• The gasket is easy to disassemble after repair and will not damage the flange surface.
Application range of spiral wound gasket
Spiral Wound Gaskets For Sale is best installed within the specified gasket stress range to ensure a leak-free connection.
Guide ring and material selection
Centering ring
The advantages of the spiral wound gasket's outer centering ring has the following advantages; the best position between the bolts. Protect spiral wound components. Additional safety to prevent the gasket from bursting.
Used as a compression limiter to prevent overload and excessive compression of spiral wound components.
Prevent radial flow of soft packing (such as PTFE).
For these reasons, it is best to use spiral wound gaskets with external centering rings.
The outer ring is marked with nominal size, pressure rating, standard, and material.
The benefits of the inner circle.
The inner ring of the spiral washer has the following advantages:-Prevents radial flow of soft packing (such as PTFE + graphite). Reduce turbulence and flow resistance. When spiral wound gaskets are subjected to high temperatures, they are used as heat shields.
It is especially recommended to use the inner ring and outer ring for spiral wound gaskets over 600 pounds, but it is especially recommended for high temperature and high-pressure conditions to optimize the operational reliability of spiral wound sealing elements. The inner ring is essential for the PTFE-filled spiral.
material selection
The material selection of the inner ring and winding metal is usually the same as that of the flanged metal. This prevents the problems of corrosion and poor expansion. The outer ring is usually made of carbon steel with an anti-corrosion treatment. However, the ring can also be made of the same metal as the flange to prevent corrosion problems.
