Production of polyethylene pipes
In the production of polyethylene pipes, low-pressure polyethylene (HDPE) is most often used, namely from polyethylene classes PE 63, PE 80, PE 100 and PE 100+ [1] with a standard dimensional ratio SDR 41 – SDR 6, nominal diameters from 16 to 110 mm for main operating pressures 4; 6; 8; 10 bar. In most cases, PE polyethylene pipes have a uniform black color and a diameter of 20 to 1200 mm. All such products are produced in several possible…
Applications of polyethylene pipes
In the field of water supply and communications, the problem of pipe wear has existed for a long time. Rusty pipes that break through sooner or later, leaving entire areas without water supply, the heavy smell of sewage in case of accidents in sewer systems cause many problems and inconveniences for both maintenance services and ordinary consumers of these services. All this can already be avoided, due to the fact that polyethylene sewer pipes have replaced steel sewer pipes. In…
Polyethylene pipes – marking
Pipes polyethylene (PE) – polyethylene pressure and water pipes are designed for laying pipelines that transport both domestic and drinking water. Also, PE pipes are used for transportation of liquid and gaseous substances, to which the material from which they are made (polyethylene) is chemically resistant. Gas pipes are designed for underground gas pipelines that transport combustible gases. PE pipes are suitable for transporting raw materials that are used as fuel for industrial and domestic use. When designating polyethylene pipes…
