PVC lay flat hose is a new kind of liquid conveying hose on the market. It is used in mobile conveying fluid machines and irrigation projects, and has remarkable economic and social benefits. Generally, this kind of PVC lay flat hose is made of high-strength polyester and high-quality PVC synthetic materials. It can adapt to the environmental application of high pressure, corrosion resistance, ultraviolet resistance, wear resistance and aging resistance. It is mainly made of inner and outer layers of pipe blank 1. It has the characteristics of simple structure and stable performance. For example, the application of tanker trucks, short-distance energy transmission. In addition, the suitable temperature of raw materials for production is – 10 50 C. The soft and elastic pipe break can be maintained in low temperature water. It has begun to replace part of the transport function of PVC lay flat hose. PVC lay flat hose is applied in the fields of agricultural orchard drought-resistant machinery matching, engineering, mining, environmental protection, industry and so on. It is an ideal high-pressure hose for liquid transportation at present.
