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. Pipeline materials should be selected according to the situation. The commonly used PVC lay flat hose pipes are PE pipe, PC pipe, PVC pipe and PP-R pipe with different characteristics. Then their characteristics are:
1. PE pipe 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 cracking when the external pressure is large.
2. PVC pipe has excellent electrical insulation, extensibility, heat and cold resistance, dimensional stability and chemical corrosion resistance, but its hardness is insufficient compared with metal pipe, and its appearance is easy to scratch.
3. PP-R pipe has strong corrosion resistance, easy bonding, low price and hard texture. However, due to the leakage of polyvinyl chloride and additives, the water pressure and temperature can not be too high. PP-R pipe has the advantages of light weight, corrosion resistance, low resistance, sanitation and long service life.
These are the characteristics of three commonly used PVC lay flat hose. Apart from their different characteristics, the cost of various pipelines is also different. Therefore, in choosing PVC lay flat hose, we should consider the overall maintenance cost of the irrigation system and other factors comprehensively, and make a choice and purchase.
