1. PVC drainage pipes are used for drainage, such as drainage in real estate projects, rainwater, community drainage, etc. The PVC drainage pipe itself has no pressure, does not bear pressure, and has no requirements for sanitary indicators. If you want to distinguish the quality of the pipe, it depends on its toughness and tensile properties.
2. PVC water supply pipes are self-evidently used for water supply, and of course some are used for farmland irrigation. The biggest difference from drainage pipes is that they need to be able to withstand pressure. If it is for water supply projects, they also need to have Hygienic indicators, non-toxic and pollution-free and other testing indicators.
PVC drainage pipe specification table
1. Commonly used PVC drainage pipe specifications are mainly based on the nominal outer diameter, which are 32mm, 40mm, 50mm, 75mm, 90mm, 110mm, 125mm, 160mm, 200mm, 250mm, 315mm, 400mm, 500mm, most PVC drainage pipe specifications There is a certain gap, which is normal. The length of PVC-U pipe is generally 4m or 6m, and other lengths are determined after negotiation between the supply and demand sides.
2. Specifications of PVC drainage pipe The length of PVC drainage pipe is usually 4 meters or 6 meters. If you need other lengths, you can negotiate with the manufacturer to order. The nominal outer diameter of PVC drainage pipes has strict regulations, which are implemented in accordance with the national standard GB/T5836.1-2006. The specifications of the nominal outer diameter of the PVC drainage pipe are 32mm, 40mm, 50mm, 75mm, 90mm, 110mm, 125mm, 160mm, 180mm, 200mm, 250mm, 315mm, 400mm, 500mm, 630mm, etc.
3. In addition to the specifications of the PVC drainage pipe meeting the standard, its performance indicators must also meet the regulations. The appearance of the drainage pipe requires that the inner and outer walls are smooth and smooth, without air bubbles, cracks, depressions, marks, etc., and the color distribution is uniform; the tensile yield strength must be greater than 40MPa; the softening temperature should be above 80 degrees Celsius; the result of the drop weight impact test should be less than 10 %.
4. There are relatively strict regulations on the wall thickness of PVC drainage pipes. The specific requirements for the outer diameter wall thickness must comply with the GB/T5836.1-2006 standard. The longitudinal retraction rate is less than 5%, and the deviation of the same section cannot exceed 14%.
