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. […]

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. […]

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. […]

Jointing of large bore pipes. Electrofusion Couplers and Branch Saddles

In the AMI seminar, FRIATEC (www.friatec.com) introduced a new generation of electrofusion fittings Frialen –XL for PE pipe joining large diameter up to 1200mm which solves the Ovality problem and outer diameter Tolerances, that are important in these dimensions, through flexible electrofusion couplers. […]

PE100-RD: A New Generation, resistant to disinfectants, is Born

Black Hostalen CRP100-RD is a high density polyethylene and it is designed to meet the technical requirements for new drinking water systems. This material has got an improved resistance against disinfectants and provides excellent resistance to stress cracks combined with good long term hydrostatic resitance. […]

More about Aquaculture, Fish Farms and Marine Farms with PE pipes

STRUCTURES USED IN SHELTERED AREAS The first farms in the sea (or “off the land”) were installed in sheltered areas (fiords, coves, lakes), safe from the hard conditions which prevail in open sea. […]

Aquaculture, Fish farms and Marine Farms with PE pipes

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.
