Pipes must be arranged horizontally in order to avoid their
damage when they are been transported by trucks. Fasteners
must not produce scratches nor cracks in the pipe's surface.
In order to save money in transport services and packaging,
the pipes could be carried one inside another, of course,
whenever the pipe's diameters allow it. To protect the connectors,
the pipes must be placed horizontally. Flanges, projections,
acute angles parts and any kind of edges that stand out
from the pipe's surfaces, are not allowed.

Pipes must be inspected individually after being unloaded
from the truck. A designated operator must check for damages
and fissures, even though the pipes have been already tested
before in the factory. Damages or fissured pipes must be
rejected and its use is forbidden. Pipes are commonly distributed
in several ways: individually, by mean of ropes, two or
more pipes together, and using pallets.

While some pipes are been unloaded from the truck, the
others, which remains in the truck's floor, must be strongly
fixed, avoiding possible displacements. Handling properties
of PVC pipes are improved due to its very little weight,
being not necessary to drag them. In order to avoid permanent
damages, the pipes must be carried on carefully, no violent
movements should be performed with them and shocks against
hard and cutting objects must be prevented.

If the storage zone is next to the working place, you could
save money in piping transportation. The store place must
be a ventilated one, like a shed; when using a storehouse
with a roof made of duck, suitable ventilation of the top
zone must be guaranteed. The storehouse's floor must be
perfectly plane, in order to keep the pipes free of deformations.
Fulfilled the above mention conditions, the tubes will be
piled up; these stacks should not be taller than 1,5 meters
and the top pipe must be correctly fixed using ropes. You
should not store the pipes for long periods of time. Moreover,
they must be carried out to the working place only when
is completely necessary.

To determine the conduit's depth, a corresponding plan
must be follow. Please be aware that you should add an additional
depth to let the pipe to accommodate itself on the conduit's
bed. Tubes must not lie directly on the conduit's bed, but
on a thin layer made of some dense material of a height
non-greater than 10 meters. Moreover, they must be covered
from their top part to a height of 1 meter underneath the
level of the ground. At the level of pipe's top generatrix,
the conduit's diameter should be approximately 0,5 meters
bigger than the pipe's diameter. In conduits built by hand
is not mandatory that walls be perfectly vertical. Please
be noticed that the earth that has been excavated could
slip down to the conduit, so that, it should be removed
from the conduit's borderline.
Finally, it is very important to keep the conduit's bed
cleanest as possible before proceeding to install the pipe,
by taking off any kind of stones, tree roots, rocks, etc.

To obtain a perfect join, some strict requirements have
to be followed. The most important aspects to be covered
by a good join are: an efficient tightness, flexibility,
fast positioning and easy manufacturing.
|
 |
- Clean the ring's housing and then insert it.
- Verify the chamfer on pipe's end (tongue) and then write
the appropriate length in it.
- Insert the pipe's end previously lubricated, making use
of an emulsion water-soap or other non-acid lubricant. Warning:
do not use mineral greases. Please, take care of linearity
during the assembly.
|
 |
- Polish the connector and the tongue with emery paper.
- Clean and remove the grease from every component.
- Paint both ends with the adhesive using a brush. Advise:
Paint following a longitudinal line using the exact quantity
of adhesive
- Insert the tongue into the connector. Torsion efforts
are not desired.
- Take off the adhesive's excess when both parts have been
correctly joined.
- Immobilize the piping during an hour.
Note: Only use adhesives recommended
by the piping and connection's manufacturers or adhesives
than comply with IRAM standards.

Piping covering are one the most important things to be
considered when are dealing with them, so that, it must
be carefully supervised. We are not speaking about a simple
task like common people could consider it. Piping covering
is not just filling the conduit with the escavated earth.
The filling earth has to offer a hard and continuous support
all along the tube's length (including joints and connections).
The filling material directly in contact with the piping
and until a uniform height of 15 cm over its superior generatrix,
must be constituted by sifted fine or sandy earth (sand
preferably) that does not contain elements of greater diameter
than 3mm. Once the piping is lying on the conduit's bed,
the covering procedure begins. Their flanks are filled up
until covering half of the pipe and then, the earth is pushed
against the pipe's flanks and pushed to the bottom part
of the pipe using a shovel. The cover has 15 cm over the
pipe's superior generatrix. The compactation have to be
done on that filling material that does not lie over the
pipe, providing the piping with hard lateral supports, increasing
thus its strength to resist the earth's stresses. The final
cover is performed using the former excavated earth, taking
into account that this earth is free of big particles (less
than 10 mm), like stones and animals or vegetable's garbage.
This final covers is made of several interlaced layer of
compressed earth (no more than 30 cm each one).
