As an indispensable tool for agricultural irrigation in modern society, PVC lay flat hose is widely used and plays an important role in modern agricultural irrigation. The material of hose road should be selected according to the situation. The commonly used PVC lay flat hose roads are PE hose, PC hose, PVC hose and PP-R hose.
And so on, their characteristics are different. Then their characteristics are:
1. PE hose has some flexibility, and has the advantages of stable and reliable interface, good stress cracking resistance, chemical corrosion resistance, aging resistance, etc., but its hardness is poor, and it is easy to cause fracture when the external pressure is large.
2. PVC hose has excellent electrical insulation, elongation, heat and cold resistance, dimensional stability and chemical corrosion resistance, but its hardness is insufficient compared with metal hose channel, and its appearance is easy to scratch.
3. PP-hose has strong corrosion resistance, easy bonding, low price and hard texture. However, due to the exudation of polyvinyl chloride and additives, the water pressure and temperature should not be too high. PP-hose has the advantages of light weight, corrosion resistance, low resistance of hose channel, sanitation and long service life.
These are the characteristics of three kinds of commonly used PVC lay flat hose. Besides their different characteristics, the cost of each hose road is also different. Therefore, we should consider the overall maintenance cost of irrigation system and other factors in choosing PVC lay flat hose.
