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. […]

METHODS OF REPARATION OF PLASTIC PIPES

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 [...]

Conditions for the installation of plastic drainage pipes

Conditions for the installation The plastic drainage pipes allow a quick and simple installation due to their lightness and flexibility. The supply in rolls and the bars of 6 m facilitate the handle and installation. […]

Plastics piping Systems in Polyethylene (PE) for the supply of gaseous fuels

In the 60s of XX century, plastic pipes had begun to be introduced in some areas of Catalonia and Andalusia using rigid PVC pipes. At that time natural gas was still not and gas distributed (“city” gas or “manufactured”) it was locally manufactured from petroleum and in some cases still from coal. […]

Why using Trenchless Technologies (NO-DIG) with plastic pipes. IbSTT

Pipes, as well as building facades, need to be rehabilitated within a few years. Between 25% and 40% of existing pipeline networks in Europe need to be rehabilitated, to avoid causing damage to human life and environment. […]

Polyethylene (PE) as pressure pipe material. Its classification

In recent times, the importante of Polyethylene (PE) plastic pipes in the design of public networks, private and industrial water supply, sanitation and gas pressure has considerably increased. This trend confirms the confidence in the PE as pipe material, mainly due to increased knowledge and experience about it which actually  exists worldwide. […]
