When do we recommend spiral wound gaskets?

Before starting with the content that concerns us - the one that refers to which sectors and applications are targeted by the spiral wound gaskets - it is interesting that we define with which materials and how these are manufactured. type of sealing gaskets. This information will help us to understand its importance in certain contexts that require very demanding sealing systems.

What is a spiral wound gasket?

It is a part used to seal two metal surfaces together and prevent possible leakage in very demanding environments. The main characteristics of spiral wound gaskets are:

• - They are constructed from a metal strip that is wound in a spiral and alternated with a soft material that acts as a filler.
• - While the “V” metal band gives it elasticity to allow the joint to regain its shape, the backfilling ensures a good sealing. The material used for the filler - PTFE, graphite, ceramic fibers or mica - will be determined by the scenario in which the gasket is to play its role.
• - They have a good mechanical resistance.
• - Support extreme temperatures.
• - They can working at different pressure levels, even in zero pressure environments.
• - They guarantee a high corrosion resistance by a wide variety of substances.

For which types of industries do we recommend spiral wound gaskets?

This type of industrial seals is mainly intended for all manufacturing processes involving low and high temperatures (from cryogenic up to 450 ºC), pressures up to 400 bar and/or generating steam. in situ. In this way, spiral wound gaskets are used in production plants in all types of process industries. such as petrochemical, iron and steel, sugar, pulp and paper industries. They are also in great demand by our customers working in the zinc, copper and fertilizer sectors, among others. In short, spiral wound gaskets are an interesting sealing option for all those applications where there are very high or very low temperatures and pressures. At Epidor SRT we have a gasket stock according to EN 1514-2 and ASME B16.20 standards and in the most common sizes, in order to offer a fast service to our customers.
