Graphite yarn

Graphite yarn

Graphite yarn is in two types, thin and thick and in two cross-sectional and round cross-sections. If the graphite yarn is in the cross-sectional area, it is called packing, but if it is round, it is called refractory yarn. If the refractory yarn is thick, it is called refractory rope, and if the refractory yarn is thin, it is called yarn, which you can use by hand and by machine.

Refractory yarn with a rectangular cross-section called graphite packing is mostly used for sealing, insulation and sealing.

Thick refractory yarn called refractory rope such as refractory packing can be used for insulation, sealing and sealing.

Thin refractory yarn is also used for sewing fire-resistant equipment, which can be used both by machine and by hand.

Graphite refractory yarn is composed of graphite fibers that have brittle properties, so in addition to graphite, 98% of carbon fibers are also combined in it. This process has improved the flexibility properties of this product.

The most important advantages of graphite refractory yarn are:

It has good resistance to dangerous rays such as ultraviolet rays.
Has acceptable flexibility.
Has the ability to control pressures.
It has a long life.
In humid environment, heat tolerance up to 650 ° C, in dry environment, 550 ° C and for high use, 400 ° C is set.
Can be used in various environments.
Graphite rope has good resistance to chemical corrosion and good performance in alkaline and acidic environments.
At temperatures below zero and negative, its shape and dimensions are strong.
Oxidation resistance decreases if the temperature rises above 400 ° C.
It has good electrical conductivity.
It has good resistance to abrasion, tension and mechanical resistance.
With the mentioned advantages of graphite yarn, we will use this yarn in different fields:

Use in humid environments
Used in environments with hot steam or oil
Sealing of rotary engines and nuclear reactors
Sealing of parts in marine, water and sewage, power plants, paper and pharmaceutical industries
Insulation of various components in the field of gas, oil, refineries and petrochemicals
Graphite refractory yarn is available in dimensions of 25 to 4 mm.
