Product Overview
ZHENGJI SPIRAL WOUND GASKET
A spiral wound gasket is a semi-metallic gasket. It consists of a spirally wound v-shaped metallic with a non-metallic filler material. There are three elements that constitute a spiral wound gasket. They are:
Outer ring:
Also known as a guide ring or centering ring, the outer ring of a spiral wound gasket is usually made of carbon steel material.
The main purpose of this element is to center the gasket while inserting it into a bolted flange joint.
Inner ring:
The inner ring is one of the most important parts of a spiral wound gasket as it prevents windings from buckling inside the pipe. In the situations of buckling of a gasket, parts of it get sucked into the pipe and eventually flow through the piping system to get caught/wrapped on something. Inner rings prevent this phenomenon and help in avoiding the problem.

Inner rings prevent this phenomenon and help in avoiding the problem.
Sealing element:
This is the element of the spiral wound gasket that creates a tight seal to prevent leaks. The sealing element encompasses both windings and filler material. In general, spiral wound gaskets use a flexible graphite filler material rated for high temperatures. Graphite as filler material also helps the gasket avoid flange distortion and joint misalignment. Another common filler material is PTFE (Polytetrafluoroethylene). However, PTFE is not suitable for use in high-temperature applications.
