Flexible graphite metal spiral wound gaskets are widely used in boiling water, steam, high-temperature, and other applications. Many people may have heard of flexible graphite spiral wound gaskets, but how much do you really know about their properties and uses? Today, we will take you on a journey to learn more about them. Flexible graphite spiral wound gaskets are made from natural flake high-carbon graphite as raw material, processed and refined through unique chemical and physical treatments to produce pure graphite products.

In addition to possessing the excellent characteristics of natural flake graphite, they also have outstanding features such as flexibility, resilience, corrosion resistance, high-pressure resistance, radiation resistance, and heat transfer. This material is woven from low-sulfur expanded graphite yarn and lined with cotton yarn to enhance its strength. It has a low friction coefficient, does not damage pump shafts and valve seats, and exhibits good heat transfer properties, solvent resistance, and high resilience.

The base material of the graphite metal spiral wound gasket is processed and woven from flexible graphite composite coils. It is primarily used for static and dynamic sealing at the mating surfaces of gate valves, pumps, and pipelines. This product features a wide range of applicability, heat resistance, strong alkali resistance, long service life, self-lubricating properties, and resistance to bottom friction. It is particularly suitable for applications in extreme material environments. How much do you finally understand about the spiral wound gaskets that are commonly seen in daily life?

Today, we will delve into the basic properties and characteristics of stainless steel-graphite composite gaskets. Spiral wound gaskets have excellent shrinkage and resilience properties, offering multiple sealing layers and a certain degree of self-tightening function. They are not very sensitive to surface defects on the flange compression surface and do not bond to the flange sealing surface, which can partially relieve pressure. They are affected by temperature changes and mechanical vibrations and can be used in high-temperature, low-temperature, high-vacuum, and impact vibration environments, among others, under cyclic and alternating conditions while maintaining their excellent sealing performance. Application equipment includes static sealing positions at flange mating surfaces such as pipelines, gate valves, pressure vessels, coolers, heat exchangers, towers, manholes, and handholes in industries such as crude oil, chemicals, metallurgy, power, shipping, gas, nuclear energy, aerospace, textiles, pharmaceuticals, and machinery.
