PVC drain specifications to meet the outside, its performance indicators must also be complied with. The appearance of the drain pipe requires that the inner and outer walls should be smooth and smooth without any bubbles, cracks, dents and marks, etc. The tensile yield strength should be more than 40MPa; the softening temperature should be above 80 degrees Celsius; the result of falling weight impact test should be less than 10 %.
PVC drainage pipe wall thickness of the more stringent requirements, the outer diameter of the wall thickness of the specific requirements to comply with GB / T5836.1-2006 standards, the longitudinal retraction rate of less than 5%, the same cross-section of the deviation can not exceed 14%.
