I. Polypropylene internal sewage pipes
The polypropylene sewage pipes are manufactured according to the European standard EN 1451-1/2.

Applications :
domestic and industrial waters internal sewage networks;
    ventilation systems.

*Note: The pipes linear weights have been calculated at the material average density of 0,915 g/cm .

Special feature:
The pipes are made of fireproofed polypropylene within the standard class V / V (DIN 4102) or unfireproofed polypropylene - at request.
    The fireproofed poylpropylene pipes have a very good resistance to fire and are suitable for the internal networks within the buildings where it is necessary a high safety degree against fire.



 
Colour :
grey RAL 7037

The advantages of polypropylene pipes

As compared to cast iron pipes
very reduced pressure losses owing to the smooth internal surface during the entire lifetime of the pipe
    non-toxic material for the environment
    good elastic characteristics
    superior degree of thermic and phonic insulation
    high chemical and electrochemical resistance
    reduced weight
    simple and fast mounting
    lower cost price
 
As compared to PVC pipes
better mechanical resistance at high
temperatures (up to 95° C) and at low
temperatures (in the winter)
    better elasticity
    short period for the networks to be put into work
    reduced weight
    fire resistant, do not emanate toxic gas
    thermic dilatations taking over make do without specials pieces for all temperature scale

Major advantage: the rate PRICE-QUALITY (higher quality at very advantageous prices)

Joint type
Elastică

Socket type
Ring socket (dismountable)

Joining mode
Sealing with elastomeric rubber rings
    For pipes mounting in PP networks, it is recommended to use PP fittings owing to their chemical resistance, high fiability and lack of sediments.
    The PP network connection to the metallic or other materials networks can be made using adequate passing fittings.

Approval:
The PP pipes are certified by a Technical Building Approval.

Environment protection:
non-toxic material for the environment;
    products are recyclable;
     they do not damage the ozone layer.

Accessories offered by TERAPLAST :
polypropylene sewage fittings;
    elastomeric sealing rings.



 
Delivery lengths:
250, 500, 750, 1000, 1500, 2000, 3000 ± 10 mm.
    The above lengths represent the usefull pipe lengths.
    At customer`s request pipes can be cut at any other lengths

Packing:
palletized, using PP injected props;
    in boxes (pipes with a diameter of 32,40
and 50 mm at lengths of 250 and 500 mm)

Storage:
on pallets.
    Avoid long UV exposure

Handling and transport:
Handled avoiding the pipes contact with aggressive substances and abrasive materials. The pallets with PP pipes do not be superposed and to be side fixed during the transport.

Mounting:
The polypropylene sewage pipes are automatically sleeved on the processing line and bevelled for aneasier mounting and to protect the rubber sealing.
    The fireproofed polypropylene pipes joining within networks is made simply and rapidly using sockets with elastomeric sealing rings, the mounting
following the next steps:
 
it is checked the perpendicularity of the cutting against the pipe axis, as well as the bevelling quality;
    the joining parts (sealing, pipe and/or fitting) are carefully cleaned of abrasive impurities;
    the rubber ring is automatic inserted in the pipe socket with the “V” side to the internal part of the pipe;
    the pipe / fitting end is lubricated on its entire circumference;
    the elements to be joined by a longitudinal push
    The network achieved this way will be clamped
under the socket using collars.
