Water pipe pressure, sealing requirements of the line resistance to breakdown and so on
PVC to the water pipe, wall thickness, high strength, pressure, diameter generally medium PVC drain, wall thin, medium strength, the key general larger PVC threading pipe, indoor use, thin wall, small diameter, outdoor can have different caliber The copy. The The Another threading tube is the name suggests is to wear wires and the like, so the compressive strength will be small
Water pipe wall thickness is much. Can withstand more than .8MPa pressure line pipe wall is very books, can not bear pressure
