Spiral wound gasket

How does a spiral wound gasket work? What are the benefits of spiral wound gaskets? What is the purpose of an inner ring in a spiral wound gasket? Why do we use spiral wound gasket in flanged joints?

Many spiral wound gaskets for critical applications include an inner guide ring also, which gives the gasket a greater resistance to thermal shock and in the case of vacuum service prevent the filler material being sucked in. Inner rings should be used with spiral wound gaskets on male-and-female flanges, such as those found in heat-exchanger, shell, channel, and cover-flange joints.

The spiral wound gasket is semi-metallic, comprising of a spirally wound v shaped stainless steel strip and a non-metallic filler material, such as graphite or PTFE. Also on the gasket , is a solid outer ring used for centering and controlling compression. Spiral wound gaskets are designed for ASME B16.

Custom filler, winding strip, guide ring and inner ring materials are available upon request. Our spiral wound gaskets have types: 1. 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.

Spiral - wound gaskets comprise a mix of metallic and filler material.

This style of the gasket , the. Generally, the gasket has a metal (normally carbon rich or stainless steel) wound outwards in a circular spiral (other shapes are possible) with the filler material (generally a flexible graphite) wound in the same manner but starting from the opposing. Free Shipping Available On Many Items. The CG spiral wound is a good general purpose gasket and is suitable for use with flat-face and raised-face flanges. All gasket specifications are sized to meet ANSI standards.

Gaskets for ANSI Class 1flanges are compatible with low-pressure pipe. To read more about Gasket Selection click HERE. Flexseal Industrial is a full line gasket and o-ring distributor. The sealing element is manufactured by interleaving plies of alternating metallic winding strip and filler to create a gasket that is robust and easy to install. Maxiflex spiral wound gaskets can be manufactured using a range of filler materials according to different service conditions.

Outer guide rings are fitted to centralise the gasket between the bolts and to act as a compression limiter. Spiral Wound Gaskets Class 1- Dimensions of Spiral Wound Gaskets Class 15 ASME B16. Multiple wraps of metal and filler in the spiral create barriers that reduce the possibility of leaks.

They can be manufactured in various metals depending on the operating temperature, media, and compatibility. SPIRALTEC SPIRAL WOUND GASKETS.
