    REDI PIPES and REDI PRESSURE PLUS UPVC pipes are manufactured by the United Lebanese
    Industries ‘’ULPI’’ under REDI License and from unplasticised polyvinyl chloride polymer which is a
    thermoplastic material using the extrusion process. The manufacturing and quality control
    processes are carried by REDI Laboratory and Bureau VERITAS Lebanon

    REDI PIPES and REDI PRESSURE PLUS UPVC pipes meet the requirements of the Water
    Services Association and are recommended for use in potable water supplies by municipal
    authorities.
    The high strength to weight ratio together with exceptional resistance to corrosion or chemical
    attack makes these pipes ideal for major infrastructure applications.

    REDI PIPES and REDI PRESSURE PLUS UPVC pipes are suitable for:

              Major potable water supply trunk and reticulation mains
              Industrial process pipelines
              Effluent pipelines for pumped sewage, industrial and rural wastes
              Slurry pipelines carrying abrasive and corrosive mine or quarry materials
              Irrigation and turf watering systems

    Operating Conditions
    The pressure/temperature relationship of uPVC is an important part of behavior of the pipe at elevated
    temperatures. For applications which need additional safety factors, e.g. more safety than included in
    the service design coefficient of 2.0 or 2.5, the allowable operating pressure shall be selected according
    to table 2.

    The whole system allows the operating pressure to be that of the component having the lowest
    pressure rating.

    Laying Instructions
    The long run performance of pressure PVC system relies on the quality of laying as well as of the
    surrounding material. A tight control is highly recommended through out all the laying stages,
    whereby a particular care has to be taken during the installation of system subject to low
    temperature. On this respect it is recommended to refer to the manufacturer for special instruction.
    Laying conditions have to abide by European Norm EN1452-6.

    Test Methods

    People believe that manufacturing Quality pipes is easy. In fact, by going through the standard, one
    must follow the process, and may access the conformity with the requirements only when the following
    tests have all been carried out successfully:

        • Visual Control
    Aspect, roughness, opacity, conformity of color, shape of socket, spigot, chamfer, porosity, detect any
    trace of burning, clean cut, no irregularities, … all those controls are performed without magnification,
    they allow to detect any eventual trouble in the manufacturing process at the closest points of the
    extrusion lines

        • Dimension Control
    Outside diameter, wall thickness at the weakest points, etc…), ovality (out of roundness), angle of
    chamber, length of chamber, mean outside diameter (by calculation), mean wall thickness (by
    calculation)

       •   Gelification
       Product is tested by immersion in methylene
       chloride, a very corrosive solvent, @15°C during 15
       minutes. Product tested should show no attack at
       any point of the pipe (internal, external, thru the
       wall), proving that the fusion temperature has been
       reached. If this point is not reached, the filler used
       in the formulation for lubrication flows between the
       molecules to the surface, and proves that the
       polymerization is not complete, and thus that the
       properties of uPVC are not met.
       This ageing test reveals the imperfection of the
       product. A product is in compliance if the mix of
       temperature-pressure-speed is well tuned in order
       to reach the fusion point (very variable acc to
       product, conditions, material, …) but still not
       reaching the degradation stage (burning); because
       the measurement of the degree of fusion is very
       costly and almost impossible to obtain with the
       number of variables, the solvent test is a
       substitution considered as very accurate




8
    •     Longitudinal Reversion
    A sample of the product is immersed in an
    oven during 30 minutes at 150 degrees: all
    tensions are released at this temperature
    considered as the beginning of fusion (fulfilled
    at 180 degrees). The product is then cooled at
    ambient temperature, and the deformation
    measured (shrinkage acceptable if smaller
    than 5%. This test helps to identify some
    processing abnormalities that might affect the
    pipe dimensions at long term, by evaluating
    the effect of heating on the pipe.




           •   Vicat Softening Point

        A sample is immersed in oil and the
        temperature is elevated from ambient until it
        reaches it s softening point (minimum
        acceptable is 79 degrees). Softening point is
        reached when a calibrated needle under a
        weight of 5kg penetrates up to 1 mm into
        the product. Higher point demonstrates the
        ability of the pipe to withstand high
        temperature (especially for soil and waste,
        as well as for pressure pipes).

     •   Impact Resistance

     A calibrated weight from a specified height falls on the product a number of times, without any
     friction:
     passing the test demonstrates the impact resistance of the PVC product




     •   Formulation Inspection

 It allows to verify that the PVC content complies with the requirements of the standard (at least 80%
 by mass for soil and waste, and more than 88% for pressure pipes), failing which the pipe will not
 withstand long term operation (50 years). This test allows to demonstrate that the filler content
 (calcium carbonate used as lubricant) does not exceed a reasonable percentage of the mixture. By
 using calibrated graphics, it gives more or less the same results as the ash test




10
 Marking

 Should be in compliance with the requirements
 of the standard as well as those of the brand,
 should include all useful data allowing the
 traceability of the manufacturing process and all
 the steps of the quality control

 Pressure Testing
 Carried out regularly at high pressures, with comfortable safety factors, to demonstrate that the
 product may be used in normal conditions, at the working pressure rated on the product (tests
 performed externally)

 Suitability for Potable Network
 Since our standard pressure pipes are manufactured lead-free, we also are in a position to provide
 the results of suitability for drinking water installation (metal content in compliance with the
 regulations as defined by Ministry of Health) tests performed externally (IRI)

 Additional tests are performed regularly to demonstrate the compliance of the product, such as
 water tightness of rings, bending tests, etc… Those tests are not mandatory but it is recommended
 to perform them in order to verify the quality of the mix

 In parallel, additional tests are performed on the rubber rings, the adhesives, etc… to demonstrate
 that the system made of pipes, fittings and miscellaneous accessories do comply with the
 requirements of the standards (assessment of conformity of the system)




11
 Conformity of raw material

 The verification of the suitability of raws requires costly instruments that are not available in
 Lebanon; this is why ULPI only purchases raw-material from sources that are certified ISO-
 9001:2000, and that may demonstrate the compliance of their products with the latest International
 Standards.
