What is the PVC garden tube for low-pressure irrigation?

PVC Garden pipe, also known as pouring pipe, is PVC resin as the main raw material, add the right amount of additives, through mixing, extrusion, diameter, cutting and expansion process processing molding is plastic pipe. PVC Garden pipes Low-pressure irrigation pipes are usually designed to transport water sources that usually come from pumps or natural water sources, such as a stream or lake, and are called low-pressure irrigation pipes due to their relatively low pressure.

(1) PVC Garden tube has a small flow resistance, Rroughness of 0.008 to 0.009, Water transmission capacity is 20% higher than that of cast iron pipe, Concrete pipe increased by 40%; (2) PVC garden tube, The tensile strength at 23℃ shall not be lower than 45 MPA; (3) Good compression resistance, Pressure to 1 / 2 of the outer diameter will not break, Good mechanical properties; (4) Light in weight, Convenient for shipping, The specific gravity of PVC-U pipe is only 1 / 5 of steel cast iron pipe, Of 1 / 2 of the concrete, 1 / 4 of the same size and length of the ductile iron pipe, 1 / 10 of the concrete, Transportation cost is reduced by 1 / 2-1 / 3; (5) The pipe health is non-toxic, No secondary pollution flow, Will not produce secondary pollution to the water quality; (6) PVC Garden tube has good corrosion resistance, Have excellent acid resistance, alkali resistance, corrosion resistance; (7) Low cost, Convenient for the construction, The service life at stable temperature is not less than 50 years under pressure.
