ASME B16.20 which covers spiral wound gaskets requires the use of solid metal inner rings in.. Pressure Class 900, nominal pipe sizes 24 and larger, Pressure Class 1500 from nominal pipe sizes 12 and larger, Pressure Class 2500 from nominal pipe sizes 4 and larger and all PTFE filled gaskets. For example, ASME B16.20 has spiral wound gasket size charts in tabular formats that provide all required dimensions with respect to pressure class and pipe size. Masterpac Spiral Wound Gasket uses Micatherm filler material . When ordering it providing complete specifications is required: inside dimensions (AxB), width (b) and thickness (s) or a drawing. Inner Ring : Solid inner metal ring acts as a compression stopper. The strength and the flexibility of the spiral wound gaskets allow them to be used in pipelines to make leak proof connections.

You will learn the following; Knowing color coding is extremely important if you are working in the field, as a small mistake in selecting the wrong gasket can result in a loss of time and money, which no one likes. for -1" NPS, all ratings not specified by API 601 dimensions shown are manufacturers standard - purchaser to specify if different dimension required. There is no specific standard for this type of gasket. The main purpose of this element is to center the gasket while inserting it into a bolted flange joint. Wherever there is a flanged joint on a pipe, valve or pressure vessel, we can provide a proven gasket product that will ensure the joint is strong, safe and totally reliable within the planned maintenance schedule of your fluid handling plant. 0000003822 00000 n

Key Benefits : These are suitable for use with flat face and raised face flanges and specified for high pressure/temperature service or where corrosive or toxic media are present. There are various other types of spiral wound gasket types that are used specifically for special applications. 0000008510 00000 n
A Spiral Wound Gasket is the most widely used common metallic gasket used in industrial applications involving a range of pressure and temperatures. . 0000003296 00000 n
For PTFE filler gasket, this style is basically not recommended due to possibility of inward buckling during compression. The metal hoop is pre-formed in V or W shaped profile, which allows the gasket to act as a spring between the flanges. Hb```KlBB b860^qB@ B1(PpN:,s7PlQd8D@}Y

Clean the bolts and lubricate them with a quality lubricant, such as an oil and graphite mixture. You may encounter "hybrid" metal gaskets in the industry that are a cross between a spiral wound and kammprofile gasket. 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. Solid 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. d2. Tolerance Outside diameter for NPS 1/2 through NPS 8 is 0.8 mm; for NPS 10 trough NPS 24 tolerance is + 1.5 mm - 0.8 mm. **NOTE - ASME B16.20 mandates inner rings on all PTFE filled spiral wound gaskets, and for 24" NPS and larger gaskets in Class 900#, 12" NPS and larger in 1500#, and 4" NPS and larger gaskets in Class 2500#. The inner ring is inert in terms of corrosion through contact with dissimilar materials, and the fire safe design also combines graphites sealing ability with mica on the ID and OD to prevent entrance of further corrosive conditions. Solid inner metal ring acts as a compression stop and fills the annular space between flange bore and the inside diameter. As said, the winding is an alternative layer of filler material and winding material. 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. 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. The cupping of the outer ring has nothing to do with the spiral windings. Very good information about spiral wound gaskets.!!! Why did we call it SWG? 0000005582 00000 n
