PVC is a thermoplastic made mostly of carbon, which is acquired from oil and gas via ethylene, and chlorine, which is obtained from industrial-grade salt. Contrary to plastics like PE, PP, PET, and PS, which are completely dependent on oil or gas, it is less dependent on natural resources, such as crude oil or gas, than other polymers and can therefore be considered a resource-saving plastic. Due to the material's inherent ability to extinguish itself, when PVC is set on fire, the flames quickly extinguish as soon as the source of the fire is removed. This feature offers PVC great fire resistance.
One of the safest and perhaps most extensively researched materials utilised in Ethiopia, Ghana and Kenya is PVC pipe. Every aspect of its manufacturing, usage, and disposal has been examined and given the green light for more than 60 years by governmental and private certification and testing organizations.
PVC is authorized for use in medical applications, consumer goods, and potable water and distribution all over the world. The most inert and secure pipe materials must be utilized in environmentally sensitive situations like salt water aquariums because it is so safe to use for intravenous medical tubing.
PVC pipes are often divided into four categories: Unplasticized PVC (U PVC), chlorinated PVC (C-PVC), molecularly orientated PVC (PVC-O), and modified PVC. In addition to having a number of similar characteristics, each kind of PVC has unique benefits for certain uses.
Yes! PVC pipes can indeed be recycled with ease. PVC pipes and other rigid PVC components can be recycled 8 to 10 times without losing their technical properties thanks to the material's special characteristics
Don`t determine the pipe size by measuring the outside diameter of your PVC pipe. You will consequently be given the wrong size. To ascertain what size PVC pipe you have, always measure an Inside the pipe's diameter.
Drainage, irrigation, plumbing, electrical conduit, and municipal water and sewer transmission
The scientific community has disproved allegations that it is toxic. According to the data, it does not release harmful organotins, offer significant risks during production, use, or disposal, build a hazardous bio-film, leach dangerous chemicals like led, cadmium, or BPA or plasticizers, or leach poisonous chemicals like lead or cadmium or BPA or plasticizers. PVC pipe cannot leach plasticizers, BPA, lead, or cadmium because these substances were not employed in its production and are not a component of the material.
The PVC pipe industry has self-standardized the color coding of PVC pipe because there are no regulatory authorities that mandate specific color coding. The standard for PVC pipe color coding in the industry is as per the standards that they follow.
Chemicals can enter a PVC pipe system through the walls or joints of the pipe if it is permeable. Numerous water distribution firms have examined the occurrence of this kind of event, and they have determined that PVC piping systems have not had any significant issues.
PVC pipes are very well suited for a variety of applications because of their remarkable resistance to chemical assault.
Industrial applications use PVC piping systems because of their superior chemical resistance. Sealing rings, however, are not advised for use in these applications; instead, solvent-cemented joints are preferable.
With the exception of the most extreme oxidizing environments, PVC is robust. All amounts of hydrogen peroxide are inert, and even concentrated solutions of oxidizing salts like potassium permanganate only result in a surface assault.
In general, aromatic and chlorinated hydrocarbons, ketones, nitro compounds, esters, and cyclic ethers should not be used with PVC since they can enter the material and cause significant swelling and softening.
For decades, the regions of Kenya, Ghana, and Ethiopia (among others) have used U-PVC pipe systems in drinking water applications due to their total safety.
Polyfab is one of the leading PVC pipe manufacturers and supplier in all major cities, including Addis Ababa, Ghana, Kenya, and Ethiopia and many more.
PVC is hard and brittle in its raw state. By adding additives, it is prepared for a variety of commercial and industrial uses. It becomes softer and more malleable due to plasticizers. Its resilience to high temperatures is increased with heat stabilizers. It is resistant to intense and prolonged exposure to sunlight thanks to UV stabilizers.
Plasticized PVC, or PVC in its pure state, is referred to as UPVC. The UPVC material is hard and brittle without softening chemicals. This prevents it from being used for pipes and other flexible applications, although it still has a useful application in building. It is utilized as siding or weatherboarding material on the external walls of dwellings in many different nations because it is resistant to prolonged exposure to heat and sunlight.
The PVC Pipe Association predicts a 100-year design life expectancy, although in practice, that prediction may be much exceeded. The engineering examination of fatigue in the PVC pipe wall, which is highlighted in several reports and independent research, is the primary source for the 100-year estimate. PVC also has a stellar track record for long-term durability.
In a study funded by the American Water Works Association Research Foundation, corrosion resistance, lifespan, and durability were highlighted as the main benefits of PVC by water utility management and engineering organizations. When these same water supply specialists were asked to compare PVC's life expectancy to those of the other popular types of pressure pipes, PVC came out on top.
Since PVC pipes are rigid, plasticizers are not added to their formulation. PVC is softened by plasticizers in products including membranes, films, flooring, and cables.
The flexibility of the PVC fittings or joint is lost if it is improperly built, or if the spigot is forced into the bell's neck. Avoid assembling past the reference mark because uneven settlement in the trench could lead to a leaky joint.
