Everything you need to know about PVC pipes!
What is PVC pipe and what are its uses?
PVC was first discovered in the late nineteenth century and is not only young in the construction industry but has a history of more than 70 years. These pipes were first produced and marketed in Germany in 1932-1939. It should be noted that some of these pipes are still in operation and samples of them have been excavated and are available without any damage.
Capabilities, especially the high strength of these pipes, led to the development of their application in various agricultural applications, water supply, sewage, transmission of electrical and telecommunication cables, well walls, etc. In the 1950s and 1960s, which is a decade of technological prosperity and growth, PVC pipes were produced from the softest to the hardest products. Due to its engineering and ability to specialize its applications based on technical knowledge and formulation, this polymer has always been considered by researchers and scientists in various polymer sciences around the world.
Existing articles on PVC confirm that PVC is not only non-flammable but also inherently self-extinguishing due to its chlorine bond. In the case of hard PVC products, this is quite obvious and testable, and anyone can easily investigate the truth of this claim by setting fire to a piece of PVC pipe. However, in the case of softened PVC products, which are other than PVC pipes, fittings and types of profiles and are referred to as products to which softener has been added, the flammability of the product is not due to the presence of PVC, but due to the softener The product happens. Proof of this claim is a simple method of extracting oil from a softened PVC sample and performing a flammability test on the remaining product, which clearly shows the extinguishing of PVC after removing the flame or combustion source from the part.
The amount of PVC consumption in the world
In the world, the use of PVC products in construction has a history of more than 50 years and their replacement instead of traditional products such as: metal products, concrete, pottery, etc. is not because of the cheapness of these products, but because of their outstanding features and benefits. Here are some of them.
- Corrosion resistance
- Chemical resistance
- Strength to light weight and light weight ratio
- Easy to install
- Ability to connect to other polymer and metal pipes
- Long-term tensile strength
- Resistance to wear and tear
- Impact strength
- Low coefficient of friction
- Lack of migration of organic matter and thus conservation
- Water quality
- Low thermal and electrical conductivity
- Flame resistance
- Provide PVC resin from low value sources and help preserve national resources
- Affordable price and recyclability
About the combustibility of PVC
PVC is inherently fireproof unless some flammable materials are added such as softeners, in which case some flame retardants can be used to prevent the ignition of this part of the additives, which is enclosed during the enclosing process and prevents oxygen from reaching the igniter. Prevents the softening oil added to PVC from burning and makes the whole product flame resistant.
The difference between PVC and U-PVC
As mentioned, the first samples of PVC products with more than 75 years of life are still working, and this is a testament to the longevity of these products.
PVC is more resistant to sunlight than other polymers, which can be enhanced by adding UV stabilizers to products such as windows that are exposed to direct sunlight.
As mentioned, the terms PVC and U-PVC have nothing to do with whether or not the product is Anti UV, but rather whether the product is softened or not softened. U-PVC means not softened PVC.
It is also important to note that so far no powdered PVC products have been found to be damaged by sunlight, even outside the standard framework. This is corrected by the fact that soft PVC products lose some of their softness and flexibility over a long period of time and the migration of some of the softeners added to the product, and will be relatively drier than the original soft product. Of course, if the production is done according to the relevant standards, these parameters have already been seen and the product characteristics test is designed in such a way that the products that comply with the standard will not suffer such damage in any way.
Commercial cinema PVC pipe is a type of PVC pipe that is known by this name in Iran. There are several types of PVC compounds in the world that distinguish them from each other. PVC pipes are considered to be the most widely used pipes in the construction industry, which are produced and offered in various types of push-fit pipes and ordinary plica pipes in different standards. Despite the limitations of consumption, PVC pipes have a bright future in the future, and this is due to the many and important properties of this material that we are dealing with.
One of the most important properties of PVC pipes is the same as PVC pipes. It cools down and turns off. PVC pipes are the same as PVC with the abbreviation of polyvinyl chloride (PVC) are responsible for more than 50% of construction costs, and this is due to its cheapness, light weight and other important factors in the production and consumption of these pipes.
Consumption of PVC pipes
PVC or PVC cider can be used in almost all cases, especially in the construction industry. PVC pipes are among the few that have all the capabilities in most areas due to their high advantages such as chemical resistance and long life. Sierra PVC pipes, depending on the type of use in projects, can be used in the following cases, which are referred to:
- Domestic sewage system
- Urban and industrial sewage systems
- Pressure and low pressure water supply networks
- Power grids as sheaths of fiber optic cables and currents for insulation of this material
- Telecommunications and related industries
- PVC pipes
Production of PVC pipes, various types of Plica consumable pipes
PVC cider pipes are produced in different sizes depending on the needs of a project, but in the meantime, the quality of PVC pipes is directly related to issues such as the type of materials used in the production and how PVC pipes are produced. Compositions of PVC pipes Various additives including softeners, fillers, stabilizers, pigments or master batch and process aid with polymer substrate which are the same as PVC, the percentage and amount of which has a special rule, if not Due to the amount of materials and compounds used in PVC pipes, the quality and fragility of pipes and other manufactured products are greatly reduced.

The size of PVC pipes is mm
PVC pipes are the same as PVC pipes (pvc) have different dimensions and sizes from each other and each of them has different thickness according to the needs of the project. Sierra PVC pipes in normal, semi-strong and pressure types Strong classifications, each of which, as mentioned, have more or less weight and thickness, which comes with the following:
- 20 mm PVC pipe
- 25 mm PVC pipe
- 32 mm PVC pipe
- 40 mm PVC pipe
- 50 mm PVC pipe
- 63 mm PVC pipe
- 75 mm PVC pipe
- 90 mm PVC pipe
- 110 mm PVC pipe
- 125 mm PVC pipe
- 160 mm PVC pipe
- 200 mm PVC pipe
- 315 mm PVC pipe
- 400 mm PVC pipe
