WHAT IS PLASTIC- WHAT IS POLYETHYLENE (PE)
Plastic; (C) Hydrogen (H), Oxygen (O), Nitrogen (N) and other organic or inorganic elements, called Monomer, are formed by breaking bonds in molecular groups of simple structure into a long and chain structure called Polymer, the name given to the materials.
In order to obtain the plastic raw materials, the ethylenic monomer obtained from the distillation of the crude oil is subjected to a series of chemical processes to obtain the ethylene monomer, and then the obtained ethylene monomer is subjected to the polymerization process to obtain the POLYETHYLENE MATERIAL.
Polyethylene Raw Material Flammability Feature
Burning substances enter the group of flammable substances in environments containing 21% oxygen. For this reason, PE is in the group of flammable products. The Oxygen Index of PE is 17%. If there is 17% O2 in an environment, the PE raw material burns in that environment.
Carbon monoxide and Carbon Dioxide emerge as a result of combustion of PE raw materials. Carbon monoxide is toxic to humans. The most disadvantage of PE is that it is produced from petroleum and therefore has high flammability.
DIN 4102-1 and EN 13501-1 standards indicate that polyethylene is in the normal flammable group. The PE spontaneously flames at a temperature of 350 ° C. PE fires are extinguished with water, foam, carbon dioxide or dust.
General Properties of Polyethylene Pipes
Petrochemical developments have resulted in end-to-end developments in the diversity of plastic raw materials. Pe raw materials (PE 32 - LDPE) are found in the first form and that are used in drinking water pipes from 1950’s. PE 63 raw material was developed and used in low pressure systems and it could be used in natural gas systems with maximum 4 bar. After PE 63, PE 80 raw materials were started to be used. It was used in drinking water and natural gas networks. In the beginning of 1990, PE 100 raw materials have become an economic solution in providing a high performance for drinking water and natural gas networks.
Polyethylene Pipe Wall Thickness
Even the external conditions in the production region affect these tolerance values. Polyethylene pipe measurements such as Polyethylene pipe wall thickness, Polyethylene pipe diameters, Polyethylene pipe weight are calculated based on the mentioned tolerance values. Hdpe Pipe, Polyethylene are ranked according to strength classified according to the density of previous technological developments. Polyethylene pipe Pn4-Pn32 can be done between the manufacture of Polyethylene pressure pipe system and the special production pipe of the desired diameter and size. The pipe pressure classes have been subjected to many tests especially during transport of drinking water. As a result of the Polyethylene pipe tests, all the reports are positive, there is no harmful effect on human life.
