The transformation of the plastic materials by extrusion (pipes) or by injection (fittings) allow us working with very tight manufacturing tolerances that make it easy the tightness of the different elements of plastic material which are part of a water network (sewer, supply, etc.). Such small tolerances can’t be got with other kinds of materials, for example of cast concrete.Leer más


Historically the batteries of water meter were made of galvanised iron, being of limited duration with the pass of the time especially to the oxidation and corrosion. From the end of the last century it is being installed batteries fabricated with PE or PPR pipes and fittings and configured the through Socket Welding.Leer más


I believe that it is very interesting what was commented by JUAN ANTONIO PEÑA MARRUFO, Design Engineer, within the group of LinkedIn AIDT (Spanish Association of Engineers and Designers of Pipes) so here I reproduce the text, extended with some image that I have looked for this occasion. The comment is related to the published posts about trenches and their supports and that you can see in:Leer más



This kind of process is used to join a pipe with a fitting from 20to 110 mm of diameter. It is performed by heating the external surface of the pipe and the internal surface of the fitting up to achieving the fusion of the material, and then it is inserted one in another while the material is still hot. The pipes and welding fittings can be of PE, PP, PB or PVDF but both of the same material.Leer más


The most important factor

The most important factor in an installation of plastic pipes is the QUALITY OF THE INSTALLATION, that is, the result of having performed according to the normative and procedures of good practice applicable in each case, for this it is essential to know them through a specific training. There is no point in having a good pipe if we install it incorrectly.Leer más
