PVC pipe (UPVC pipe) is one of the first and most famous polymer pipes to be widely used and from PVC different types of pipes were manufactured and marketed with different applications. PVC pipes are hard to hurt and have a long life expectancy, and due to their high environmental resistance, it has quickly gained popularity among everyone and was able to water supply in many projects for sewage transfer, water supply. And use fluid transfer. Polica (Polika) with the highest technical and mechanical properties provide the right economic and environmental needs in today's world. The latest model of the Polyica (U-PVC) family is the pipe used for water and sewage around the world that does not leak and is easily installed. Pars Ethylene Kish UPVC pipe is actually the Polica (Polica) pipe, the first manufacturer of this type of pipe, called Polica, and was named after the same name in Iran, and the general public selects the name of the Polyka for gray UPVC pipes. And the name of the Polka remained on this type of tube. PVC and UPVC pipes are currently one of the most widely used pipes in buildings and construction projects, the most commonly used UPVC pipes in sewage transfer. With the progress of the polymer industry and production processes, different types of U-PVC pipes are manufactured today, with the installation and speed of these very high and easy-to-use and different types of Silent Pipes (sound pipes). Has been.
UPVC Pars Ethylene KishFit, screws, threads, adhesives and boiling are produced, each of which is used according to their use. UPVC pipes are used to transfer non -pressure or low -pressure fluids and are used for these working categories, but welding connectivity must be used for high -pressure fluids. PVC pipes (U-PVC) are not used only in buildings today and in usesDrainage, A highly trusted pipe and most drainage pipes and equipment are UPVC pipes.
U-PVC pipes(Polica)Nars are electric current and are resistant to electrochemical reactions caused by acids, bases, and salts that lead to corrosion in metals. This feature at the inner and external surfacePVCThere is. As a result, the use of the U-PVC tube in applications where there is an invasive soil is very economical.
PVCIt is resistant to many alcohols, oils and non -aromatic petroleums. It is also resistant to most corrosives such as inorganic acids, bases and salts. For the usual water supply work, U-PVC pipes are fully resistant to chemicals in soil and water. The issue of chemical resistance is only raised when there are abnormal environments or the pipe is used to transport chemicals.
The resistance of U-PVC pipes to failure is one of their important functional benefits. U-PVC pipes are capable of deforming without fractures. The U-PVC Module of A-PVC is one of the most important benefits for technical applications, especially when the soil movement or vibration is likely (earthquake and & hellip;). The high quantity of this quantity minimizes the double phenomenon in these pipes. Also, given that the thicknessBasic pipesBased on the amount of module of resin egrality consumed in the construction of the pipe, the high U-PVC modulus reduces the thickness of the pipe and increases the cross-sectional cross-section.
The high strength of the U-PVC minimizes the thickness and lightness of these pipes. U-PVC tubes have a significant light advantage that is an important immune aspect. Easy transportation minimizes working damage and facilitates cheaper installation and transportation. A person can easily carry two 2 -meter pipes of 2, but only capable of carrying less than 2.5 meters of iron pipe with the same force.
An important advantage for each sealing pipe is its connections. U-PVC (Polyica) pipes with high depths and Push-Fit connection systems have been able to remove many traditional products through this advantage.
U-PVC pipes (polyca)They are highly resistant to abrasion and scratch. it is proven thatPVC pipeThey have a much higher durability than metal, cement and clay pipes against the transfer of slurry materials.
Under normal conditions, U-PVC pipes have relatively high resistance to impact damage compared to earthenware, cement and most of the most common materials in the construction of the pipe. Despite the decrease in the impact resistance of U-PVC pipes at very low temperatures, its impact strength is still above the required level.
Tube roughness is a very important and effective factor in causing pressure drop and reducing discharge. U-PVC pipes are very low resistance to fluid flow due to its very polished interior (low coefficient and low friction). In addition, in many pipes, bacteria accumulate in rough, low -lying parts of the pipe (biofilm formation) and over time climb the water flow, which causes the flow of pressure and water health. Beverage also have a negative impact. The low hydraulic roughness of the U-PVC pipes, preventing the formation of biofilms, in addition to reducing pressure drop, prevents sludge deposition in sewage networks and reduces the likelihood of contamination in drinking water distribution networks. Therefore, the cost of maintaining these pipes is low and the initial design of the pipeline is more optimized.
The use of appropriate formulation for the production of U-PVC pipes makes it possible to use these pipes to transport drinking water in accordance with NSF 61-62 standards and ensure that lead, tin and other toxic elements such as mercury, cream, cream Cadmium and barium below are the standard permissible limits.
U-PVC tube (polyca)It is hard to fire and does not continue to burn in the absence of the external source of the flame. The spontaneous flame temperature is 2 degrees Celsius, which is much higher than most of the building materials. As a result of PVC burning, HCL gas is released, which prevents oxygen from accessing the ignited area. That is why PVC is called a self -sacrificing substance.
In addition to the privileged benefits listed forU-PVC (Polica) pipes,The price of these pipes is very reasonable and competitive with other polymer, metal, cast iron and & hellip pipes; Are. So today U-PVC pipes in the world are one of the main options in water and sewage networks
UPVC pipes the samePolyethylene pipesNot to be added to them, and most non -standard and non -standard manufacturers affect the quality of the PVC pipe by adding additives known as the filler and the production pipe is fragile. The more brittle and drier in the appearance of the UPVC tube, the closer to the non -standard limit andStandard UPVC pipeIt should be soft and not easily crack and fail. In the field of UPVC pipe production, it is very inappropriate and cheating, and when purchasing the UPVC pipe, pay attention to the standard badge, the manufacturer's name and the standard number on the pipe. Because the UPVC tube used to cover the cable cannot be used for sewage transfer and may not be sufficient.
Building the market as a complete reference is the first and only specialized system of the construction industry in the country. Buyers can refer to the market construction system to view the prices of various construction products. The market building system has facilitated the process of purchasing construction products for buyers by establishing direct relationships with manufacturers and sellers. The products available in the market manufacturing system have valid standards and certificates.
Manufacturers and suppliers can register in the market construction system and participate in the special sales festival by placing construction products and inserting the suggested price and increase the sale of their products.
