Concrete hose is an important material for pumping concrete. It is widely used in building construction, road construction and many other industries. Such material handling hose is used to deliver abrasive materials. Thus it has a certain service life. But what will affect its service life? Raw material quality Good water raw materials can significantly…
Rupture Cause The hydraulic hose has been subjected to excessive pressure for a long time, exceeding its rated working pressure. It may be caused by unreasonable system pressure setting, safety valve failure, etc. In addition, the hose may be subjected to external mechanical wear, scratches, extrusion, etc. For example, friction with other parts, scratches by…
Providing power transmission The rubber air hose is a key component that connects pneumatic tools and compressed air sources. Its main function is to safely and efficiently transmit compressed air to pneumatic tools and provide power for pneumatic tools. For example, in a pneumatic spray gun, the compressed air transmitted through the rubber air hose…
Visible damage to the appearance Cracks When cracks appear on the surface of concrete hose, regardless of the size of the cracks, close attention should be paid. Smaller cracks may gradually expand, affecting the structural stability and sealing of the pipe. If the crack width exceeds a certain limit, or the number of cracks is…
Pesticide and fertilizer spraying Pesticide spraying In agricultural production, crops need to be regularly controlled for pests and diseases. PVC spray hose sprays pesticides evenly on the surface of crops to form a protective film, which effectively prevents the invasion of pests and diseases. PVC spray pipes are corrosion-resistant. Therefore, they can resist the chemical…
Compared with ordinary PVC steel wire hose, fiber-reinforced PVC steel wire pipe has the following advantages: Higher strength Ordinary PVC steel wire pipe mainly relies on steel wire to provide strength and support. While fiber-reinforced PVC steel wire pipe adds fiber materials such as glass fiber and polyester fiber to the PVC matrix. These fibers…
In cold areas, PE hoses are usually more suitable than PVC hoses for the following reasons: Low temperature resistance PE hoses PE material has good low temperature resistance. Therefore, it can still maintain good flexibility and elasticity in cold environments. Even if used for a long time under low temperature conditions, PE hoses are not…
PVC air pipe and rubber air pipe are both common materials. PVC air hose has the following advantages over rubber air pipes: Low cost PVC is a synthetic material with relatively abundant raw materials and low cost. Therefore, the price of PVC air pipes is usually cheaper than that of rubber air pipes. This makes…
The hot air hose itself does not generate hot air. Its working principle mainly involves the delivery and containment of hot air. And to a certain extent, the control of heat transfer. Delivery channel The hot air blower hose usually has a smooth inner wall. When the hot air enters one end of the hose…
Environment and storage Suitable temperature Rubber oil hose is sensitive to temperature and are generally suitable for use in an environment of -20℃ to 80℃. If the temperature is too high, the rubber will age and soften faster. This will cause the strength of the oil hose to decrease and leak easily. If the temperature…
