PVC Fiber Reinforced Hose is a commonly used industrial hose. Cooperative ventilation equipment is widely used in ventilation, exhaust and collection of smoke and dust in the harsh working environments such as engine room, basement, tunnel, municipal pipeline engineering, underground cable maintenance, mechanical shipbuilding engineering, fire rescue and smoke exhaust.
Brief introduction of pvc fiber reinforced hose
PVC reinforcing hose is a kind of building material, which is made of fine steel wire and wrapped in aluminium foil. It is used for ventilation of high-rise buildings, such as central air conditioning. Another is to use two layers of aluminium foil to fill glass wool in the middle so that it can insulate the air through its interior, so this kind of hose is also called thermal insulation hose. Its specifications are: 10 cm, 15 cm, 20 cm, etc.
Structure and Characteristics of fiber reinforced hose
(1) Tin foil, PVC material composite process
(2) It can be telescoped and adjusted according to the need, which is light and convenient for construction.
(3) Long-term durability, strong sealing.
Nylon mesh cloth, polyester, thermoplastic or PVC materials are commonly used for vacuum hoses. Generally with a retractable design, with high-temperature resistance, oleic acid resistance, flame retardant, insulation, free connection, lightweight and other characteristics.
The definition generally involves the following parameters:
The distance (m) that a medium can pass per unit time (seconds). Better ventilation rate can reach 30 m/s.
Common temperature ranges are - 40 ℃ to + 120 ℃, instantaneous temperature up to + 150 ℃
Calibre weight and pressure
The calibre is the inner and outer diameter of the hose, usually expressed in millimetres (mm).
Weight is usually measured in kilograms per meter.
Vacuum hoses are generally allowed to operate under low-pressure conditions not higher than 0.05 Mpa. In special cases, the vacuum will be required to withstand a certain negative pressure.
