Hdpe spacers

design and Quality

the RaCI spacers are the result of an in-depth
structural, design and production analysis assisted by
the solid modeling systems. so they represent the best
compromise between mechanical resistance and used
raw material.

the RaCI spacer collars are divided into eight families
covering a wide range of diameters. all elements are
designed according to their different applications.

they must therefore offer certain static and dynamic
characteristics, as to ensure a successful pipeline
insertion into the casing pipe.

each family offers different heights so that the collar
rings can overcome flanges, coupling joints, socket joints,
or simply to obtain a better centering.

HeigHts are availaBle frOM 15 tO 200 MM.

special versions of spacer elements made of other
polymers may also be produced in accordance with the
mechanical and temperature resistance values required
by customers (the variations of the raw material are
linked to minimum order batches, due to production
requirements).

Marking batch number to ensure
an efficient control in terms of traceability.

Quality cOntrOl

all RaCI tests are carried out by our laboratory
according to the standard UNI eN 527-2. For each
production batch, 10 specimens are tested to check
that the design characteristics are always satisfied.

Once the mechanical characteristics are verified,
we start the produc¬tion of the specific batch, by
marking each element with the same batch number,
in order to ensure its traceability.

During production, all elements undergo a
dimensional control in accordance with the
construction drawings and before packaging they
are visually inspected to ensure that all elements
reach our quality standards.

the RaCI quality department also schedules the info@raci.it - www.raci.it - Tel. +39 02 262.351
testing of some specimens for creep phenomenon,
by simulating the application on a pipeline and by
performing the ageing cycles in a climatic chamber
for a duration of 15 days with temperature
excursions from -20°C to +80°C.
