Manhole sealing washer
One of the most important and also the most widely used industrial products in the field of washers; The sealing gasket is manhole. As the name implies, manhole washers are used for sealing devices, boilers, etc. Manhole sealing gasket is made of fireproof fabric and also a layer of graphite has been stretched on this product to create strength and also increase the heat tolerance.

The uses of the manhole are as follows:

Closing the hole as well as sealing the furnace

Sealing all types of boilers and other types of industrial boilers

Create reverse current in nuclear composites

Can be used in a variety of humid, dry, semi-dry environments and ...
As you can see, fireproof fabric has also been used. In this part of the text, we will examine fireproof fabric.
Fireproof fabric :

Refractory fabric is a fabric that is woven from refractory fibers such as fiberglass, fiberglass and the like. This product is made of high quality fibers and materials that can withstand the required high temperatures and remain stable. Refractory fabric, also called flame retardant fabric.

This product also includes many synthetic fabrics. Especially for nylon, polyester and acrylic, which do not catch fire easily.

There are different methods for weaving refractory fabrics, such as warp and weft or satin. The type of yarn used to make refractory fabrics, as well as the type and style of texture, are effective in their flammability.

Despite all this, these types of fabrics melt when exposed to fire. This melting creates a very hot and sticky substance that can sometimes spread the burn and cause more severe damage. All of these should be considered by specific consumers.
Main types:
Asbestos refractory fabric;
Fiberglass fireproof fabric
Pure graphite fabric
Silicone cloth
