Advantages and disadvantages of plastic pipes:

1. Advantages of plastic pipes:

(1)It has good chemical stability, is not affected by environmental factors and medium components in the pipeline, and has good corrosion resistance.

(2)The thermal conductivity is small, the thermal conductivity is low, the thermal insulation is good, and the energy saving effect is good.

(3)The hydraulic function is good, the inner wall of the pipeline is lubricated, the drag coefficient is small, and it is not easy to accumulate. The flow area inside the pipe does not change with time, and the probability of pipe blockage is small.

(4)Compared with metal pipes, the density is small, the raw materials are light, the transportation and the device are convenient, sensitive, simple and easy to repair.

(5)It can be bent naturally or has a cold bend function. The coil supply method can be selected to reduce the number of pipe joints.

2, Disadvantages of plastic pipes:

(1)The mechanical function is poor, the impact resistance is unsatisfactory, the rigidity is poor, and the straightness is also poor, so the pipe card and the hanger are densely arranged.

(2)Poor flame retardancy, most plastic products are flammable and thermally decomposed during incineration, releasing toxic gases and fumes.

(3)The coefficient of thermal expansion is large, and the elastic compensation is necessary to be very important. Therefore, in the implementation of plastic pipes together, technology needs to be overcome to overcome its shortcomings.
