SPIRAL WOUND GASKETS

OGF Spiral wound gaskets were developed to meet the high demands of the oil refinery industry. This gasket is widely used in many industries such as oil, gas, and petrochemical industries. This metallic gasket today is used in industrial plants as it can withstand high temperatures, pressures, and chemical attacks while preventing any leaks that could happen during their intended lifespan.

Spiral wound gaskets are constructed out of different parts and materials depending on the circumstances the gasket will be in. These gaskets are constructed of three different sections comprising an outer ring, a spiral ring, and an inner ring. Each section can be made of different materials to ensure the best seal for industrial use.

The outer ring, sometimes called the centering or guide ring, is used to center the gasket when you insert it into a bolted flange joint. Typically, bolts are on the joint to ensure positioning when placing the gasket on. This outer ring is usually constructed out of carbon steel.

The sealing element also referred to as the spiral winding, is the area that creates the seal and prevents any leaks. This area also has the filler material and the spiral wounds that create the proper seal. The filler material for the oil and gas industry is usually made from PTFE or a flexible graphite material that is rated for high temperatures.

The inner ring is an important part of the spiral wound gasket. This section of the gasket prevents and buckling or any sort of damage to the gasket itself. This is important as damage caused to the gasket could go through the pipeline and cause damage internally to the pipe or the pump. This part of the ring is not necessary but will prevent damage to the filler material if thrown around or in high-pressure sealing situations.
