Vinoplastik Company is one of the well-known manufacturers of UPVC pressure and non-pressure hydraulic pipes in Iran, which offers its products in four areas: industrial towns, water and sewage companies, Jihad Keshavarzi and regional water companies. In recent years, Vinoplastik has been able to supply the pipes and fittings of many companies operating in these four areas, as well as bring good currency to the country.

() Because of the characteristics of the conical screw, the feeding section has a large diameter, and the heat transfer area and shear speed of the material are relatively large, which is conducive to the plasticization of the material. The screw diameter of the metering section is small, reducing the heat transfer area and the shear speed of the melt, so that the melt can be extruded at a lower temperature.

Hydraulic pipes are generally divided into two categories: pressure pipes (under pressure) and non-pressure pipes (sewage). Vinoplastik Company is one of the leading manufacturers of these piping systems in the country, which provides its products to customers using the latest tools and using strong materials such as UPVC. PVC pipes and fittings have very good resistance to fluids containing chemicals and at the same time have little friction with different materials. In addition, the weight of these pipes is very low and they are transported as easily as possible. The use of UPVC in municipal water transmission networks as well as sewage under compressed and non-compressed piping has proven its efficiency well.

In order to determine the overall change in static pressure of liquids and fluids as they flow along a large tube, all three components of the Bernoulli equation must be considered separately and then combined. Changes in the height or slope of the pipe may cause a pressure drop. Similarly, a change in fluid velocity can increase the pressure and vice versa. The net effect of these currents depends on the relative magnitude of these changes.
