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.Leer más

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.Leer más
