SWG CG/CGI/R/RIR Spiral Wound Gasket for Steam Line
The SWG (Spiral Wound Gasket) is a type of metallic gasket used in flange connections in various industries such as oil and gas, chemical, and petrochemical. SWG Gasket is designed to provide a reliable and durable seal under high pressure and temperature conditions.
The SWG CG,CGI,R,RIR Spiral Wound Gasket is made from a metallic strip and a filler material wound in a spiral pattern. The metallic strip is typically made from stainless steel, carbon steel, or other high-strength alloys, while the filler material can be graphite, PTFE, or other materials that provide good sealing performance. The winding process creates a Spiral Wound Gasket with alternating layers of the metallic strip and the filler material, which provides excellent mechanical strength and sealing performance.
The SWG CG,CGI,R,RIR Spiral Wound Gasket can be used in a variety of flange connections, including raised face, flat face, and ring type joint flanges. The Spiral Wound Gasket is designed to fit into the groove of the flange, which provides a sealing surface for the gasket. The Spiral Wound Gasket is compressed by the flange bolts, causing it to deform and fill any imperfections in the flange surfaces. This creates a tight and reliable seal that can withstand high pressures and temperatures.
One of the advantages of the SWG Gasket is its ability to withstand extreme temperatures and pressures. The Spiral Wound Gasket can handle pressures up to 2500 PSI and temperatures up to 1000°F, making it an ideal choice for applications that require a high level of sealing performance. Additionally, the SWG Gasket can be coated with materials such as soft iron, copper, or nickel to enhance its sealing performance.
The SWG CG,CGI,R,RIR Spiral Wound Gasket is also designed to be reusable. Unlike other types of Spiral Wound Gasket, such as sheet gaskets, the SWG Gasket can be removed and reused multiple times, as long as it is not damaged or deformed. This makes it a cost-effective solution for applications that require frequent maintenance or replacement of flange assemblies.
In conclusion, the SWG CG,CGI,R,RIR Spiral Wound Gasket is a highly reliable and durable sealing solution for high-pressure and high-temperature applications. Spiral Wound Gasket is unique spiral wound design and high-strength materials make it an ideal choice for the oil and gas, chemical, and petrochemical industries. With proper installation and maintenance, the SWG Gasket can provide a long-lasting and cost-effective sealing solution.
Basic Type
Basic construction type, inner and outer diameters are reinforced with several piles of metal without filler to give greater stability and better compression characteristics. - Suitable for tongue and groove, male and female or grooved to flat face flange assemblies.
Inner Ring Type
Solid inner metal ring acts as a compression stopper. To prevent accumulation of solids, reduce turbulent flow of process fluids and minimize erosion, damages of gasket between flange bore and the inside diameter, the annular space is filled up by solid inner metal ring. - Suitable for male and female pipe flanges.
Outer Ring TypeSolid outer ring accurately locates the gasket on the flange face to give the additional radial strength to prevent the gasket blowout and acts as a compression limiter. In case of installing the outer ring, it is very easy to install the gasket to flange face because the end of outer ring will touch at bolts - Suitable for use with flat face and raised face flanges. For class 900 and above an internal ring is recommended.
Inner & Outer Rings TypeA inner ring and outer ring type gasket will give an additional compression limiting stopper for gasket inner and outer side. It will prevent the corrosions on flange face at annular space. - Suitable for use with flat face and raised face flanges and specified for high pressure / temperature service - Class 900 and above or where corrosive or toxic media are present.
Typical Applications
Pipe, valve, pump, thermal exchange, condensing tower, plain hole and man hole of flange, etc. Petrochemical, chemical, mechanical manufacturer, power station, metallurgy, shipbuilding, medical and pharmaceutical unclear power station and navigation, etc.
