Real solutions for the 5 trillion pieces plastics that currently littler our oceans

   There are currently over 5 trillion pieces of plastic our oceans. Ocean currents gather plastic trash basically in 5 main patches around our oceans, largest one between Hawaii and California, at the Great Pacific Garbage Patch.   This is an actual serious environmental problem, which is starting to affect our ecosystems, our own health and economies. If we don’t do anything, situation can get even worst. Solving the problem will require closing the source and cleaning up what is [...]

Want to triplicate Your Daily Welding Output?

Last post, we discussed various fusion standards and how the ISO High Force standard in particular — an option that is achievable with McElroy equipment — can produce twice as many fusion welds per day with less cooling time required. Today, we would like to highlight the McElroy machine features that make the large-diameter pipe fusion process even more productive. These special features allow us to produce three times as many fusion welds a day as other machines using the ISO [...]

Want to Double Your Daily Welding Output?

If you wish to double your daily welding, we will explain how. With this machine we can weld the double welding of 250mm pipe lines daily. Over the years as HDPE has been installed in pipelines worldwide there have been numerous welding standards created, almost one for each country, for example UNE, UNI, DVS, WIS, ANSI, ASTM. The ISO standards were created in an effort to harmonize the various standards and create one set that would encompass the best procedures and [...]

Aquaculture is the farming of fish, molluscs, crustaceans and algae in “more or less controlled” conditions. It constitutes one of the few industrial activities developed by the man who is integrated in the environment from the higher and most exquisite of respects helping, not in only few occasions, to its regeneration. This “young” activity started to be developed in the environment which is better dominated by the man: the LAND. But with the pass of time, the logical tendency has been [...]

Break pressure manholes and calculation of the pump unit power

  • Break pressure manholes In some installations with a steep and long slope in which water goes down from a deposit, spring, etc. it is necessary to break the growing pressure which is produced in the parte inferior of the pipe with the aim of not having excessive pressure in the case that the pipe transfers the load or suffers some obstruction. […]

Do you know Trenchless Technologies (no-dig) with plastic pipes?

1) DRIVEN DRILLING. At present it is being used horizontal driven drilling with PE pipes up to 1200 mm diameter and over. It is ideal to overcome obstacles and existing services.  It allows junctions at different depths always working in the surface. It is used for any type of service. […]

10 Remarkable advantages of Polyethylene (PE) pipes

Polyethylene extrusión in the prehistory Every time I see this vignette, I think, perhaps because of professional deformation,  which perfectly represents the fundamental parameters of PE pipe manufacturing, ie, pressure (clubbed), temperature (fire) and time (depending on the bone length). These parameters are the ones we have to control during the PE extrusion. […]

Characteristics of the trench for buried plastic pipes

Realization of the trench It will be excavated up to the line of the soil provided that the soil is uniform; if the rigid elements are not covered such as stones, rocks, old bricks, etc., it will be necessary to excavate below the soil to perform the following filling. […]


The pipes of the supply network, are normally buried in the subsoil of the towns, under pavements, asphalt, paving stones, etc., covered with filling ground, gravel, graded-aggregate or buried and protected with concrete at junctions of streets or points where they can suffer high loads. It is not common that the pipes run visibly on the surface or on the interior side of visited galleries, conditions under which it would be simple to find the exact point of the damage and [...]
