How to distinguish high-quality fire-resistant silicone fiberglass braided hose from inferior casing?

Fire-resistant silicone glass fiber braided hose is a high-temperature protective sleeve, widely used to protect cables, pipes and hydraulic equipment in high-temperature environments, and is an indispensable material for modern high-temperature industries.

As we all know, the refractory casing is made of high-purity alkali-free glass fiber, and the outer layer is coated with high-quality silicone rubber. It is mostly red on the market, but other colors can be adjusted accordingly. Customer demand. The following are some of the differences compiled by Antuo High Temperature Protection Department for you. Customers can refer to it when purchasing.
First of all, once the refractory casing is in place, the first thing to look at is the silicone coating on the surface of the refractory casing. The high-quality refractory casing has a smooth surface, no acne, foam, cracks, scratches, and no impurities. The surface becomes uneven, with impurities such as acne and air bubbles.
Secondly, look at the silicone coating, the inner glass fiber weaving, high-quality fire-resistant silicone glass fiber braided hose, the inner glass fiber weaving is clean, there is no messy glass fiber, most of the glass fiber is white, you can see that some are milky white and pale Yellow; low-quality shell, loose and messy fiberglass weave. The color of glass fiber is impure and contains impurities.
After looking at these looks, you can smell the shell. The high-quality shell has no pungent smell, but the lower shell has a pungent smell, and long-term inhalation is very harmful to the human body.
Finally, you can test it with a lighter flame gun. The long-term working temperature of the refractory casing is 260 degrees, and the instantaneous temperature can reach 1650 degrees. Therefore, during the casing test, the inferior refractory casing has a very pungent smell and melts immediately, while the high-quality refractory casing will burn on the surface 10-15 minutes after the open flame. Carbonized, with an indistinct pungent smell, the inner fiberglass is still intact. This is enough to distinguish the pros and cons of refractory casing.
Note: High-quality refractory casing can fully protect the safety and normal use of pipelines, hydraulic equipment and other equipment in the event of high temperature or direct fire, while poor-quality casing is the possible loss caused by fire and other hazards and becomes unmeasurable. When selecting a fire resistant silicone fiberglass braided hose, choose the right product.
