PVC plastic ventilation pipes are used at a temperature of 95 degrees Celsius, and the thermal conductivity of the product is only 1/200 of that of steel pipes, so it has insulation function. The strength of the hot melt interface is higher than that of the pipe body, and the joint will not break due to soil movement or load effects.
PVC plastic ventilation pipes are lightweight, simple in welding process, and convenient in construction. When the fluid moves inside the pipe, the friction between the fluid and the pipe wall, as well as the friction between the fluid, generates resistance to the fluid's movement inside the pipe, overcoming the resistance to work and causing energy loss.
In hydraulics, the frictional resistance inside PVC plastic ventilation pipes is lost, including head loss, frictional head loss, and partial head loss. The head loss is equal to the sum of frictional head loss and partial head loss in each section.
The sidewall data of PVC plastic ventilation pipes may cause some deformation and instability, resulting in some tensile cracks. Therefore, the forming limit of the pipe bending can be determined based on the plastic relative elongation, i.e. elongation, of the data.
PVC plastic ventilation pipes have corrosion resistance, are light in weight, convenient in equipment, and do not require protection during use. However, using steel as a drainage pipe for shared engineering projects often requires coating due to its susceptibility to corrosion during use, resulting in high protection costs.
