Usage areas of PVC pipes, it is used in drinking water networks and waste water networks in the infrastructure of cities and settlements. It is used in discharge lines and pool systems. It is used in underground and above pressurized water transport systems.
It is used in agricultural irrigation systems. It is used in pressurized drinking water networks. It is used in electrical and communication systems. It is used in chemical and industrial facilities. It is used in fire networks. It is used in sewage, sewage and waste material discharge systems.
What are the reasons why PVC pipes have so many uses?
The reasons for the widespread use of PVC pipes are clear. With the developing technology, the increasing population and human-based investments will continue to increase. As long as it continues, the use of PVC pipes will continue to increase in many projects. The place and importance of PVC pipes in our lives will continue to provide water, which is the most basic and most important need of our lives.
What are the differences and usage areas of Rigid and Flexible PVC pipes?
PVC has two usage areas as rigid and flexible. Rigid PVC is mostly used for pipes, window profiles, wall coverings, etc. used in the fields. They are resistant to weather conditions, have high strength, hard and non-self-combustible material properties. Flexible PVC is used in flooring, shoe and slipper soles, medical applications and many other applications.
Do PVC pipes have a flammable effect?
One of the most commonly known mistakes about PVC raw material is that PVC is dangerous because it has a flammable effect. In order for the PVC raw material to self-ignite, the temperature required in the environment must be 450 °C. However, it has a very low melting point and burns very quickly.
After combustion, HCL (spirit of salt) emerges. If we start from here, the Carbon Monoxide gas, which causes poisoning during the fire, has nothing to do with the burning of PVC. Here we know that the spirit of salt is also poisonous, but people can see the danger of poisoning by perceiving the smell even in a very small amount of odor such as 5 PPM in the spirit of salt.
If we summarize briefly, a burned PVC pipe reveals salt spirit, and when people smell this salt spirit, they perceive it as a fire harbinger. In other words, PVC is a stimulant to people instead of starting a fire. When we hold PVC to an open fire, it will burn naturally like other plastics. But when we pull it out of the fire, this fire will stop immediately. The reason for this is the emergence of the spirit of salt formed during combustion, as we mentioned above, and extinguishing the burning place by cutting the amount of oxygen in the burning area.
Is there a standard regarding the burning property of PVC pipes?
As it is known, substances that can burn in environments with less than 21% oxygen are called “flammable”. PVC raw material, on the other hand, is classified as the least flammable plastic raw material defined as Class V0 in the classification of flammable materials. According to DIN 4102 standards, PVC raw material is shown as “Flame Extinguisher”, which is class B1. According to another evaluation, THE INSTITUTE CSI OF BOLLATE institute calls PVC raw material and products made of this material as “non-flame-proof” products.
Do PVC pipes cause cancer?
There is no evidence or report about PVC, which started to be used in industrial technology in 1930, that has been tested or approved in any way to cause cancer. More importantly, PVC comes first among the plastics approved by the World Health Organization for the storage and transportation of food products. But there is an important point here; During the polymerization process, if the amount of Vinyl Chloride remains in the raw material at a level that threatens human health, it may create a risk.
However, today, this amount can be monitored thanks to closed reactors and the polymerization process is continued until it drops to 1 PPM, that is, one per million. So much so that the containers in which the materials used in the medical field are used are also made of PVC. The reason for this is of course the tests and the fact that PVC is not in a structure that will affect human health, which is one of the most important features.
