A pipe can be defined as a conduit made of various materials such as metal, plastic, wood, concrete or fiberglass. Pipes and fittings are used to transport liquids, gases, slurries or other particles. A piping system usually consists of many different fittings that are selected depending on the design. Pumps, heat exchangers, valves and tanks are also part of the piping system.
Piping systems are the main artery of industrial processes and play a special role in advancing the activities of most factories and workshops. Pipes and fittings make up a significant portion of the total factory costs, which is equivalent to one-third of the total investment. Fittings located in a confined area pose a major challenge for plumbing and industrial support engineers.
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.
Fluid and fluid transfer systems are usually made of different types of plastic. Manufacturers of these products have to consider many things in the production line, one of the most important of which is the CEN / TC155 standard. In summary, this standard contains important requirements in the field of pressure and non-pressure pipes, some of which are summarized below:
Transfer from drinking water pipes in urban and rural areas: Sanitary and technical requirements related to rapid water transfer
Liquefied gas transmission: Safety requirements including piping system insulation
Sewage transfer in different areas: Requirements related to the resistance of the piping system against chemicals and the degree of their reaction with fluid materials
Materials that can be used in sewage and municipal water supply systems
Many materials are used in the manufacture of pressure and non-pressure pipes, which we will discuss below:
ABS (Crylonitrile butadiene styrene): Pipes made of ABS are usually used as building sewage pipes due to their reasonable price and chemical properties. These pipes also show good resistance to heat and impact.
PVC (Polyvinyl Chloride): PVC pipe is one of the most valuable products in the petrochemical industry. The price of PVC is not very high and its pipes and fittings can be easily assembled. In the past, PVC was considered a suitable pressure pipe, but now it has given way to some of its more advanced types such as UPVC. This material is also used to produce vinobond power pipes.
– PVC: PVC pipes are also often used for large-scale hot water transfer due to their very high resistance to heat and shocks. Inexpensive samples of this material are also used to transport wastewater.
Unplasticized Polyvinyl Chloride: PVC pipe is produced without any softener and therefore has higher resistance and less friction with the material. This product is often used for various pipes and fittings, transfer of drinking water in areas with different topographic conditions, drainage and even sewage transfer. Low price, excellent mechanical properties, extraordinary resistance to chemicals are among the significant advantages of this unbreakable pipe that can attract the attention of any company.
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.
Compression pipe (pressurized) is commonly used in urban drinking water and pressurized sewage systems. These pipes are made of strong materials such as UPVC and are installed both above ground and underground. It is worth noting that pressure pipes made of vinoplastics are resistant to UV rays, which makes them a good choice for surface projects.
Compression pipe feature (under pressure)
Each of the materials that can be used in water and sewage transmission systems have special properties that have a direct impact on their price and use. Vinoplastic UPVC pressure pipe has gained a lot of popularity among domestic and foreign companies in recent years. The main characteristics of these pipes are as follows:
Very high resistance to internal and external shocks and pressures due to impressive mechanical properties
Very high elasticity compared to other models
Lack of reaction with substances such as chlorine
Based on the highest health requirements for water storage and transmission
Easy shipping and simple installation
High corrosion resistance
Low roughness coefficient and no friction with fluid materials
As the name implies, non-compression tubes are used to transfer liquids without any pressure, and gravity plays a major role in their operation. These pipes are often used to transport sewage at certain distances from the ground, but their use above ground is abundant in some mountainous areas.
Characteristics of non-compression pipe (sewer)
Because gravity plays an important role in the performance of non-pressurized pipes, these products are often produced in large sizes to create the most space for the movement of fluids and liquids. This large size pipe is mostly installed with a suitable slope and on a large scale. The main features of non-compression vinoplastic tubes are:
Slight roughness coefficient and no sediment formation in pipe walls
Production in a variety of sizes and thicknesses
High elasticity and adaptability to different environmental conditions
Very high strength against blows
Slightly reacts with chemicals
High resistance to temperature changes
Low weight and very easy installation
Buy pressure and non-pressure pipes
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.
Similarly, the plumbing equipment required for the agricultural and urban drinking water sectors is provided entirely by vinoplastics. If you have any questions about different products, please contact Vinoplasty Consultants.
PVC is perhaps the most important material used to make large-sized pipes today. This unbreakable pipe weighs much less than other options and is therefore much easier to install and operate. PVC pipes and fittings are used in most food factories, industrial laboratories and drinking water and sewage transmission lines.
Application of large size pipe
Large size pipes offer many benefits to customers to use them for various purposes. Among the applications of these pipes, the following can be mentioned:
Urban and rural drinking water transmission lines
Fluid material transfer chain in plastic production plants
Transportation of chemicals in disinfectant production workshops
Large-scale rainwater pipes
Agricultural land modernization process
Relationship between pressure drop and flow rate in piping
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.
The old adage that “liquids and fluids always flow from high pressure to low pressure” is not entirely accurate. A more accurate way of expressing this is that “fluids and liquids always flow from a higher energy region to a lower energy region.” When evaluating different areas, experts always consider these points and then recommend the right products to customers.

Uses Large size pipe
Today, pipes are used by many industries to transfer various materials and fluids, and they are very important from this day. The expansion of urban life and the need to move materials as quickly as possible led to the expansion of large-sized pipes, and we are now witnessing their increasing development.
Large pipes are often used to transport drinking water in urban and rural areas, as well as to transport sewage and other waste materials, but their use extends even to chemical, pharmaceutical and packaging companies. Developed countries are still at the forefront of the production and consumption of large-sized pipes and fittings, and demand for these products is projected to increase dramatically in the coming years.
Large size pipe price
Factors such as cost of raw materials, registered regulations, service life, thickness as well as the overall size of the pipe affect the price of pipes. Similarly, other factors, such as the initial price of crude oil and gas, indirectly affect the plastic pipe market. In any case, the price of PVC pipes is much cheaper than materials such as aluminum, steel or iron.
The factors mentioned above are not the only factors affecting the price of pipes. Obviously, replacing or repairing underground water or sewer pipes is expensive, so you need to be very careful in choosing them. In the meantime, you should also consider the installation costs.
Vinoplastik Company, with years of experience in the production and supply of various pipes and fittings, offers a variety of products to customers. After reviewing the products and also receiving guidance from vinoplastics consultants, you have the opportunity to choose the appropriate option for your project and then make the necessary plans to use it.
