PVC pipe

PVC threaded pipe has 16   20   25   30   40   50   75   90   110   

PVC drainage pipe is available 40    50   75   90  110   160  200   250   315   400   500

PVC there are pipes for water supply 20   25   32   40   50   63   75   90   110   160   200

These are commonly used.

 

Product Characteristics of PVC Drainage Pipe

1. The surface hardness and tensile strength of the pipe are excellent, and the safety coefficient of the pipeline is high.

2, aging resistance is good, 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 pipeline friction coefficient is small, the flow is smooth, not easy to plug, maintenance workload is less.

5, the material oxygen index is high, belongs to B2 flame retardant material, has self extinguishing.

6, the linear expansion coefficient of the pipeline is small, 0.07mm/m.0c, and the deformation amount is small under the influence of temperature. The thermal conductivity and elastic modulus of the cast iron drain pipe are smaller than those of cast iron drain pipes.

7, pipe fittings and pipe fittings can be bonded, the construction method is simple, the operation is convenient, and the installation efficiency is high.


In addition, if you have not used PVC pipes before, or are unfamiliar with the dimensions of PVC pipes, we strongly recommend that you review the following three important details about the size of PVC pipes:

1.The outer diameter is not the size of the PVC pipe.

2.PVC plan is very important

3.Some pipes are not compatible


The outer diameter is not the size of the PVC pipe.

You should always use the inside diameter of the tube to determine the size of your PVC tube. If you measure the outside diameter of a PVC pipe and order it based on this measurement, you will almost always receive a larger PVC size than expected. Do not order PVC products based on the outside diameter.


PVC schedule is very important

The PVC Schedule (abbreviated as SCH or Sch.) is the thickness of the PVC pipe wall. The most common schedule is 40, but Schedule 80 PVC can also be used. As the schedule becomes larger and larger, the pipe wall becomes thicker from the outside, so the inner hole (hole) of the pipe becomes smaller.


In order to get the correct PVC size guide, carefully read the markings on the pipe and measure the physical dimensions of the pipe. Compare with other objects if necessary.


Some pipes are not compatible

Not all types of pipes are suitable for PVC fittings. For example, the outer diameter of steel pipes and pipes is the same size as the corresponding PVC pipe and is dimensionally compatible, but it is not recommended for use with PVC fittings and fittings because it is not possible to connect the steel pipe to Plastic PVC joints. In most cases, the steel pipe can easily slip out of the fitting, causing the structure to loosen or possibly collapse.
