Corrosion Resistance:

U-PVC (polyvinyl chloride) pipes are non-conductive and resistant to electrochemical reactions caused by acids, bases, and salts that lead to corrosion in metals. This property exists on both the internal and external surfaces of PVC pipes. As a result, the use of U-PVC pipes in applications where aggressive soil is present is very cost-effective.

High Chemical Resistance:

PVC is resistant to many alcohols, oils, and non-aromatic petroleum substances. [PVC pipe – polyvinyl chloride pipe] This material is also resistant to most corrosives such as inorganic acids, bases, and salts. For typical water supply works, U-PVC pipes are completely resistant to the chemicals present in soil and water. The issue of chemical resistance only arises when unusual environments exist or when the pipe is used to transport chemicals.

High Elastic Modulus and Flexibility:

The resistance of U-PVC (polyvinyl chloride) pipes to failure is considered one of their important functional advantages. U-PVC pipes can deform without breaking under load. The elastic modulus of U-PVC is one of its significant advantages for technical applications, especially in conditions where soil movement or vibration may occur (earthquakes, etc.). The high value of this quantity minimizes the phenomenon of double curvature in these pipes. Additionally, since the thickness of sewer pipes is determined based on the elastic modulus of the resin used in the pipe's construction, a high modulus of U-PVC leads to reduced pipe thickness and increased flow cross-section.

Long-Term Tensile Strength:

U-PVC (polyvinyl chloride) pipes are formulated to have high long-term tensile strength. The minimum required strength (MRS) (used in the design of pressure pipes) for U-PVC pipes is approximately twice that of corresponding values for other plastic pipes such as polyethylene. For this reason, the thickness of U-PVC pipes is less than that of other plastic pipes, resulting in a lower weight [PVC pipe – polyvinyl chloride pipe], which is a significant advantage.

High Strength-to-Weight Ratio, Lightweight:

The high strength of U-PVC minimizes the thickness and weight of these pipes. U-PVC pipes have a significant lightweight advantage, which is an important safety aspect. Easy transport minimizes work-related injuries and facilitates cheaper installation and transportation. A person can easily carry two 6-meter pipes of size 110, but can only carry less than 1.5 meters of 110 iron pipe with the same force.

Sealed Connections:

An important advantage of any pipe is the sealing of its connections. U-PVC (polyvinyl chloride) pipes, with high insertion depth and push-fit connection systems, have been able to replace many traditional products due to this advantage.

Wear/Scratch Resistance:

U-PVC (polyvinyl chloride) pipes exhibit very high resistance to wear and scratches. It has been proven that PVC pipes have significantly higher durability compared to metal, cement, and ceramic pipes in the transfer of slurry materials.

Impact Strength:

Under normal conditions, U-PVC pipes have relatively high resistance to damage from impacts compared to ceramic, cement, and most common pipe materials. Despite a decrease in impact resistance of U-PVC pipes at very low temperatures, their impact strength remains above the required level.

Low Roughness:

The roughness of the pipe is a very important and effective factor in creating pressure drop and reducing flow rate. U-PVC pipes, due to their very smooth internal surfaces (low roughness and friction coefficient), exhibit very low resistance to fluid flow. Additionally, in many pipes, bacteria accumulate in the rough and uneven parts of the pipe (forming biofilm), gradually blocking the flow of water, which leads to pressure drop and negatively affects drinking water quality. The low hydraulic roughness of U-PVC pipes, by preventing biofilm formation, not only reduces pressure drop but also prevents sludge deposition in sewer networks and reduces the likelihood of contamination in drinking water distribution networks. Therefore, the maintenance costs of these pipes are low, and the initial design of the pipeline is optimized.

Water Quality:

The use of appropriate formulations for the production of U-PVC pipes ensures that these pipes can be used for drinking water transfer in accordance with NSF 61-62 standards, ensuring that lead, tin, and other toxic elements such as mercury, chromium, cadmium, and barium are below the permissible limits of the standard.

Flame Resistance:

U-PVC (polyvinyl chloride) pipes are difficult to ignite and do not continue to burn in the absence of an external flame source. Its self-ignition temperature is 454 degrees Celsius, which is much higher than most building materials. When PVC burns, HCl gas is released, which prevents oxygen from reaching the ignited area. This is why PVC is referred to as a self-extinguishing material.
