Prefabricados Delta operates four factories;
two in Humanes (Madrid) and another two
in Puente Genil (Cordoba) where it offers its
customers the best pipe solution for each
project, either metal sleeved concrete pipes
(post-stressed or reinforced and elastic or
welded joint) and fibreglass-reinforced po-
lyester pipes, as well as its experience in
the water sector.
Besides pipes, Prefabricados Delta supplies
other products, such as special parts for
hydraulic systems, railway sleepers, and
concrete arches.
GFRP Pipes
These pipes provide great resistance to abrasion which
makes them particularly adequate for using in places with
aggressive fluids (industrial applications) and are classified
according to their ND (Nominal Diameter), NP (Nominal Pres-
sure) and NR (Nominal Rigidity). The pipes are manufactured
using mainly three materials: a matrix made of non-saturated
polyester resin, reinforced with glass fibre in the interior of the
matrix, and an inert material (generally quartz/silica) which is
incorporated in the matrix as a structural load.
