With the development of agriculture, water-saving irrigation of PVC lay flat hose will be the market choice. Efficient utilization of water and soil resources and close integration of economic, ecological and social benefits are the goals pursued by sustainable agriculture. Developing water-saving agriculture is the main way to solve the water supply crisis in northern China. It is also the need of building modern agriculture itself. Water-saving irrigation based on water resources and agricultural water demand law is an important part of achieving this goal. We have broken the traditional concept of agricultural water use and established an agricultural water supply system to meet the needs of modern society and modern agricultural development. Therefore, PVC lay flat hose has great market potential in the future irrigation industry.
What are the characteristics of PVC lay flat hose?
PVC lay flat hose is a hose for transporting high pressure water or foam and other flame-retardant liquids. Traditional PVC lay flat hose is lined with rubber, and its appearance is wrapped with linen knitted fabric. Advanced PVC lay flat hose is made from polyurethane and other polymeric materials. There are metal discussions in the middle of the PVC lay flat hose. Another PVC lay flat hose can be added to extend the interval or to connect the nozzle to increase the liquid radiation pressure.
The characteristics of PVC lay flat hose are as follows:
1. The fabric layer of PVC lay flat hose should be knitted evenly with neat appearance, without jumping double warp, broken double warp, jumping weft and scratch.
2. The thickness of PVC lay flat hose lining (or covering layer) should be average, and the appearance should be smooth, without wrinkles or other defects.
3. The nominal dimension and service of the inner diameter of PVC lay flat hose shall conform to the rules.
4. The length and size of PVC lay flat hose should conform to the rules in public service.
5. PVC lay flat hose’s planned task pressure and withstand pressure should not be lower than the rules.
