To date, the Prague polypropylene pipe is very popular. It is made of polymeric materials, the quality of which was approved by the transnational concern Borealis AG, the UK INEOS and the Sabic concern, which is located in Saudi Basic Industries Corporation). Each batch of raw materials must be attached to a certificate confirming the high quality of these products. It also indicates all the necessary technological parameters. The manufacturer is carefully made that the material is made in full accordance with all current standards. Features of the pipe of Pragma
The pipe of Pragma, which is intended for the sewage system, must be completely sealed, which means that there should not be any bubbles, cracks or other defects on its surface, which may contribute to the deterioration of its service life or operational characteristics. On the outer surface of the product can only be minor traces left during the mechanical processing.
The difference from analogues
The main difference between this product and other analogues is a fifty -fifty column, which has additional stiffener ribs. A proprietary marking indicating the manufacturer is placed on each of them. If there is such a designation on the workpiece – this means that the product is fully authorized and is of high -quality.
These products are designed to lay underground aquifers at a distance of more than a meter from any structure or directly below it. Pragma polypropylene pipes have a very useful structural indicator – ring flexibility. Engineers call such a quality elasticity, because, being under the influence of vertical loads, products can be deformed very elastic. Moreover, their structure does not change at all, but simply takes the form of an ellipse. Such deforming pipes act on the soil according to the principle of the reverse reaction, which significantly decreases the tension of bending. This unique ability of the product to return to the initial position means that when a load caused by the transmission of the soil occurs, the pipe of pragma retains its original shape, and all the acting voltage is redirected to the ground. Hard pipes do not have the ability to adapt, so they accept all the arising loads on their structure. This leads to the formation of cracks on the case of the product, which, subsequently, leads to its failure.
