Nylon fabric duct hose has been widely used in transportation loading and unloading process, the loading and unloading work is often conducted, and the commonly used equipment has a chute unloading grain, etc. Nylon fabric duct hose can be connected on the pipe which the temperature change is wide to form a kind of protective measures. As a result of solid in heat bilges cold shrink, although the length variation is not big, but to prevent it happens deformation of the object, but there is a huge force, when the temperature of 40, elongation is only about 0.0005 meters. If it is not allowed to stretch, it will exert a force of 104 Newtons on the object constraining it.
The larger the cross-sectional area, the greater the force. Therefore, it is necessary to consider the force generated by thermal expansion in engineering and take necessary measures. A steel bridge, for example, must have one end of the frame placed on a movable support so that the bridge can expand and shrink freely.
If the laying of railroad tracks, it is also a section to leave room for expansion. A type of tubular rubber product used for conveying gas, liquid, slurry or granular materials. By inside and outside adhesive layer and skeleton layer composition, skeleton layer material can be used cotton fiber, all kinds of synthetic fiber, carbon fiber or asbestos, steel wire, etc. The material of the inner and outer rubber of the general hose is natural rubber, styrene butadiene rubber or butadiene rubber; The oil resistant hose is made of neoprene rubber and rubber; Acid and alkali resistant, high temperature resistant rubber hose using ethylene-propylene rubber, fluorine rubber or silicone rubber.
What needs to be noted here is that the domestic nylon fabric duct hose market has gradually stabilized. And its technical strength and performance are gradually improved and close to the international insulation material market. The nylon fabric duct hose in China is also exported to many countries, and its market will be better and better in China.
