Tips】 Nantong Bao Jian: What is Aramid Flame-retardant Fabric

Aramid flame-retardant fiber (scientific name: meta-aromatic polyamide, domestically known as aramid 1313 fiber) is a permanent flame-retardant fiber, with heat resistance, high strength, high wear resistance, good flexibility, low shrinkage, chemical structure Stability, combustion without droplets, no poison gas and other advantages.

The cloth woven with aramid flame-retardant fibers has good dimensional stability and can be used at a temperature of 250 degrees Celsius for a long period of time, with a thermal shrinkage of only 1%. Fiber softening temperature of 373 degrees Celsius, more than 400 degrees Celsius began to decompose, when the decomposition of the cloth thickening, fiber expansion, cloth outside the 900-1300 degrees Celsius isolated heat transfer without cracking.

1, the original liquid dyeing: Fiber filament before adding dye, spinning weaving, never fade.

2. Post-dyeing: dyed with yarn or cloth made of fiber, with color fastness, dry and wet friction above level 3

Weaving cloth can be added anti-static fiber, the cloth can be treated with oil and water repellent, made of clothing has the following functions:

1、Permanent flame resistance, limited oxygen index Loi greater than 28

2. Permanent antistatic properties

3, permanent acid and alkali and organic solvent erosion

4, high strength, high wear resistance, high tear resistance

5, in the case of fire, no droplets are produced, no toxic gas is produced

6, when the fire cloth surface thickening, enhance the seal, does not break

Aramid flame-retardant clothing can be widely used in fire, military clothing, petroleum industry, power industry, natural gas industry, metallurgical industry, coal industry, aviation industry, marine industry, automobile and other industries.

Angle Valves

Globe Valves and angle valves are designed for throttling or regulating flow in commercial and industrial applications. Bronze, cast iron, or cast ductile iron materials. Threaded, flanged, or solder end connections.

Angle valves for use in commercial and industrial applications. Typical services include hot and cold water, HVAC, steam, compressed air, gas and other general utility services.
Vacuum angle valve is used for turn on or shut off the airflow in the vacuum pipeline, the applicable media is air and non-corrosive gases.
It has two structures, one is angle type and another is a 3-way type within an ISO-KF or ISO-F various flange end pre-pump port.
a) Small diameter (≤DN50) valve body are precision investment casting.
b) Large diameter (> DN50) valve body are molding shaped seamless steel or steel plate.
c) Bellows sealed structure can withstand 150ºCtemperature, metal sealed structure can withstand 450ºCtemperature.
d) Can install on any position to control the airflow in the vacuum pipeline, as an on-off valve purpose

Angle Valves, Angle Globe Valves, Brass Angle Valve, Zinc Angle Valve
