Spiral Wound Metallic Gasket Suppliers and Manufacturers

SPIRAL WOUND GASKET The spiral wound gasket is suitable for use across a wide pressure range and is therefore virtually applicable. The spiral wound gasket can be used to seal fluid pressures up to 250 bar and cryogenic temperatures as low 200C and up to elevated temperatures 550C. Due to its sturdy design the spiral wound gasket is simple to install without causing damage (although extra care should be taken during transportation and installation of large diameter gasket without guide rings). The outer guide ring serves to locate the spiral element centrally on the flange faces and prevent blow-out. By combining different winding materials and metals the gasket can be tailored to a wide variety of operating conditions. Due to its non-adhesive character the gasket is easy to remove after service. The gasket does not cause damage to the flange faces. BENEFITS OF THE CENTRING RING The spiral wound gasket outer centering ring provides the following benefits: Optimum location between the bolts. Protection of the spiral wound element. Additional security against gasket blow-out. Acts as compression limiter preventing overloading and over compression of the spiral wound element. Prevents radial-flow of soft fillers, such as P.T.F.E. For these reasons it is preferable to use spiral wound gasket with outer centering rings. On the outer ring is marked with nominal size, pressure class, standard and materials. BENEFITS OF THE INNER RING The spiral gasket inner ring provides the following benefits: Prevents radial-flow of soft fillers, such as P.T.F.E. Reduces turbulence-minimizing flow resistance and crevice corrosion. Acts as a heat shield when the spiral wound gasket is subjected to high temperatures. Inner and outer rings are particularly recommended for use on spiral wound gaskets exceeding class 600lbs, but specifically recommended for high temperatures and pressures to optimize the operational reliability of the spiral wound sealing element. MATERIAL SELECTION Material selected for the inner ring and winding metal is usually the same as the flange metal, in order to prevent corrosion and differential expansion problems. The outer centering ring is generally manufactured from carbon steel with an anti- corrosion treatment; however, the ring may also be manufactured in the same metal as the flange to prevent corrosion problems.

[Spiral Wound Gasket] Material Filler: GRAPHITE, PTFE, INCONEL, etc. Hoop: SUS304, SUS316L, etc. Feature The spiral wound gasket is the most ideal type having flexibility and recovery which are essential for high temperature and high pressure among semimetal gaskets. It is wound in spiral combined with V-type metal thin hoop and non-ferrous material filler. The winding start part and end part are wound by the hoop over several times and then both edge is processed by spot welding to make the gasket. The gasket has outstanding capability as it features unique structure with elastic metal and flexible filler. - Outstanding capability for high temperature and high pressure - Automatic flexibility and recovery from the change of temperature, pressure, vibration and working conditions - Efficient production for any type of dimensions such as round or oval type, etc. - Outstanding sealing capability as it is produced according to the pressure of unbalanced flange. - Hoop and Filler materials can be selected according to special operating conditions.

SPIRAL WOUND GASKET OFFERS HIGH COMPRESSIBILITY AND RECOVERY Spiral Wound Gasket is composed of a steel outer ring, a spiral wound sealing strip filler and a special steel inner ring. It is created by winding alternating strips of metal and filler material. https://www.forseall.com/ Outer guide ring is fitted to centralise the gasket between the bolts and to act as a compression limiter. Inner ring is fitted to reduce the gap between the inside diameter of the gasket and the bore of the flange. It is widely used in moderate to critical services in various industries. They are most suitable for the gaskets subject to extreme temperature or pressure cycling, shock or vibration. These gaskets have the best resistance property when compare with other metal and asbestos type gaskets. TYPES Centering gasket (Style CG). Utilizes an external ring which accurately centers gasket on flange face. It provide an additional radial strength to prevent the gasket blow-out and acts as a compression stop. A general purpose gasket suitable for both flat face and raised face flanges. Centering gasket with inner ring (Style CGI). This style is similar to style CG, but it additionally consists of an inner ring. The outer ring is used for centering and the internal ring used as an additional compression limiting stop. The internal ring also serves as a barrier to protect the gasket from heat and corrosion. Reinforced spiral wound gasket (Style R). It is a basic configuration of spiral wound gasket. The Inner and outer diameters are reinforced with several plies of metal without filler to give greater stability and better compression and sealing characteristics. Reinforced inner ring spiral wound gasket (Style RIR). This style of the gasket, the solid inner metal ring acts as a compression stop and fills the annular space between flange bore and the inside diameter of the gasket. It is designed to prevent accumulation of solids, reduce turbulent flow of process fluids and minimize erosion at flange faces. Three centering gaskets with black inner ring on a white background.
