I believe that everyone may have heard of the PVC drain pipe, but it is limited to hearing it, and it may not be so familiar to it. I guess you may want to know what specifications PVC drain pipe has, because many places need to be used, but you don't know how big the specifications are. Today we will talk about what specifications it has. By the way, its advantages, characteristics and pipe design principles.

The specification is a certain standard, which is the standard that must be observed in production and processing. The specifications of the commonly used PVC pipe drain pipe are: nominal outer diameter: 32mm, 40mm, 50mm, 75mm, 90mm, 110mm, 125mm, 160mm, 200mm, 250mm, 315mm. PVC pipes are generally 4m or 6m in length.
1. The surface hardness and tensile strength of the pipe are excellent, and the safety factor of the pipe is high.
2. Good aging resistance, normal service life can reach more than 50 years.
3. The pipeline has excellent corrosion resistance to inorganic acids, alkalis and salts, and is suitable for industrial sewage discharge and transportation.
4. The coefficient of friction of the pipeline is small, the water flow is smooth, it is not easy to block, and the maintenance workload is small.
5. The material has a high oxygen index and is self-extinguishing.
6. The coefficient of linear expansion of the pipeline is small, 0.07mm/m. C, the amount of deformation affected by temperature is small. The thermal conductivity coefficient and the elastic modulus are small, and the anti-freezing performance is superior to that of the cast iron drain pipe.
7. Pipe and pipe joints can be bonded, the construction method is simple, the operation is convenient, and the installation work efficiency is high.
1. The surface hardness and tensile strength of pipes are excellent, and the safety factor of pipes is high.
2. It has good aging resistance and normal service life of more than 50 years.

4. Pipeline friction coefficient is small, water flow is smooth, blockage is not easy and maintenance workload is small.
5. The material has high oxygen index and self-extinguishing property.
(1) The resin should be PVC-SC5 resin or PVC-SG4 resin, that is, a polyvinyl chloride resin with a polymerization degree of 1200-1000.
(2) A heat stable system must be added. According to the actual production requirements, pay attention to the synergistic effect and antagonistic effect between the heat stabilizers.
(3) Impact modifiers must be added. CPE and ACR impact modifiers are available. Depending on the other ingredients in the formulation and the plasticizing ability of the extruder, the amount added is from 8 to 12 parts. CPE has a low price and a wide range of sources. ACR has good aging resistance and high welding angle.
I believe that everyone must understand the specifications of the PVC drain pipe. You must understand it and you need it. If you need to feel free to contact us, we can answer your questions you don't know, and you will get your answer if you want to ask. Please feel free to contact us.
