Why polyethylene pipes three layers of German specifications? The use of new co-extrusion technology in the production of three-layer polyethylene pipes has many advantages, we mention some of them briefly: 1. Increased mechanical properties and creep strength On shrinkage and the formation of larger cracks. In this way, failure is achieved through the accumulation of small cracks. In fact, the presence of carbon mass in the polyethylene structure causes failure in two ways: on the one hand by starting to leave more easily due to stress concentration on the filler material and on the other hand by reducing chain mobility due to filler-polymer interactions. Due to the three layers of black-walled polyethylene pipes of this company, carbon mass is added only in a thin outer layer and about 50% of the pipe thickness (middle layer) no additives are added to the polyethylene and the mechanical properties are reduced and weldability is not observed. 2. Improve weldability and weld strength Therefore, since the middle layer (without additives) in the weld of polyethylene pipes is embedded in the weld surface, very high weldability is one of the characteristics of this company’s three-layer pipes. 3. Cleanliness and non-proliferation of fungus and microorganisms inside the tube. The inner layer of Pasargadae’s three-layer tube is white and contains titanium dioxide. Titanium dioxide has many benefits including: – Anti UV rays of the sun – Purification and purification of water – Ability to remove potential taste and odor in water – Preventing the build-up of germs and microorganisms – Hydrophilic and self-cleaning properties www.elitepipeiraq.com
