Molecor in its continuous commitment to the development and implementation of technical tools to support its collaborators, makes available to the market the update of the TOM^® Mechanical Calculation Program "tomcalculation.com" according to the UNE 53331: 2020 standard.

This tool has been validated by Mr. Marcos Rodríguez Millán, professor at UC3M Universidad Carlos III de Madrid, who after reviewing the calculations and validating the evidence report, was able to verify that the calculations made through the tomcalculation.com software comply with the calculations derived from the application of the UNE 53331: 2020 standard. Plastics. Non-plasticized Poly (vinyl chloride) (PVC-U), Oriented Poly (vinyl chloride) (PVC-O), Polyethylene (PE) and Polypropylene (PP) pipes. Criteria for checking the pipes to be used in pressure and non-pressure pipes subjected to external loads.

It is important to carry out the mechanical calculation of the buried pipes before planning the installation to assess the mechanical stresses that are transmitted to the pipe by the action of the different external loads. This tool with simple functionality and interaction with the user, determines the validity of the installation based on the efforts and demands that the pipe will withstand, as well as its safety coefficients against breakage and crushing.

Any pipe, regardless of the material, requires suitable installation conditions. These conditions will ensure a greater durability of the material itself.

In the case of plastic pipes, it is essential to carry out the corresponding mechanical calculation, in which, without any doubt, the internal working pressure must be taken into account.

Based on the knowledge of the working conditions of the pipeline and the terrain on which it is to be installed, the viability of the system can be ensured based on the installation conditions designed by carrying out the corresponding mechanical calculation.

TOM^® Oriented PVC (PVC-O) pipes are shown as one of the best alternatives on the market thanks to their hydraulic capacity, efficiency in the operating phase, and their low maintenance costs, due to their high physical-mechanical and chemical properties.

The molecular orientation provides the TOM^® PVC-O pipes with significant advantages in terms of product quality, installation and use, but these pipes also offer better environmental performance, thus improving sustainable development and consumption of resources. To this must be added their excellent environmental performance throughout their long life cycle.
