Azar Barzin G. Sepahan Company, year in a land with an area of thousand square meters and infrastructure of square meters with the aim of producing all kinds of PVC pipes and fittings from size to mm, in order to be used in sewage and water supply, telecommunications, electricity and A building was built. This company produces pp (polypropylene) pipes and fittings from size to mm for construction, urban, industrial, sanitary water supply and central heating installations and the transfer of chemicals, acids and compressed air in its production line.

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.

Metal pipes, despite all the preparations, usually rust after a short time and are very difficult to install. In addition to all this, water and sewer pipes are usually located at a certain distance from the ground and they will not be easy to replace or repair. The industry of materials handling and hydraulic piping has presented a suitable option to various companies, which includes the use of pressure pipes and non-pressure pipes. These pipes are often made of durable materials such as PVC and significantly increase the useful life of local plumbing. Follow the continuation of this article to study this issue and review the types of materials that can be used in pipes and fittings of fluid materials.

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.

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.
