Polypropylene is a thermoplastic and partially crystalline resin belonging to the family of polyolefins. PP is obtained through the polymerization of propylene with the aid of catalysts. For use in piping systems, the latest-generation Polypropylene Homopolymer variant, or PP-H, offers excellent performance at working temperatures of up to 95° C and a high resistance to chemicals due to the excellent physical and thermal characteristics of the resin. The PP-H line in latest-generation The PP-H line in latest-generation Polypropylene Homopolymer consists of a comprehensive range of pipes, fittings...

FIP PP-H valves and pipe have been tested and certified by DIBt (Deutsches Institut fur Bautechnik) • RINA FIP PP-H valves have been recongnised as suitable for conveying, treating domestic and air conditioning waters on board ships and other units classified by RINA. FIP fittings and valves are certified in accordance with Ukrainian Health, Safety and Quality standards FIP PP-H fittings and valves have been recognised as suitable for conveying drinking water by the NIZP (National Institute of Public Health - Poland)

Properties of PP-HThermal resistance • Service range 0 °C - 95 °C (see pressure/temperature regression curves) • High flow coefficients (extremely smooth internal walls) • Pressure drop constant over time • Low risk of stoppages due to scaling • Reduced transfer of material to the transported fluid • Suitable for conveying chemicals (excellent results with saline solutions, acids, alkalis, alcohols, water and many organic solvents.) Abrasion resistance Extremely low operating costs due to its long service life Insulating • Non-conductive (immune to galvanic corrosion) • Minimum heat loss Easy...

Socket welding instructions Hot socket welding involves fusing the pipe in the fitting’s socket. The joint is made by simultaneously fusing the male and female surfaces by means of special manual or automatic heating devices. These devices, in their simplest form, are composed of a heating plate on which a series of heating bushes are mounted. The devices comes with an appropriate heating system complete with an automatic temperature controller. No additional materials are required for this type of welding. Socket welding does not affect the chemical resistance of the PVDF, nor does it influence...

6) Mark the pipe with the insertion length L1 (fig. 6), referring to the values indicated in the table named “Pipe insertion length” and checking that any peeling has been machined to the entire length shown in the table. 7) Mark a longitudinal reference line on the outside of the pipe and the fitting to prevent the two parts from rotating while the joint is being made (fig. 7). 8) Clean the fitting and pipe from any traces of oil or dust on the weld surfaces (fig. 8). 9) After having checked that the surface temperature of the heating plate has stabilized at the required value, insert the pipe...

• For proper welding, we recommend using pipes with wall thickness exceeding 2 mm, and precisely: • for De from 63 to 110 mm: pipe series PN 16, PN 10 and PN 6.

Butt welding with contact heating elements is the process of jointing two elements (pipes and/or fittings) of the same diameter and thickness, the joining surfaces of which are heated until fusion by contact with a heating element and then, after the heating element has been removed, are pressed together to form the weld. The following instructions are provided for reference purposes only. Installers must be properly trained and have an in-depth knowledge of the procedures to be followed according to the type of welding equipment being used. Preliminary checks before welding To ensure the joint...

The butt fusion welding of pipes and/or fittings using contact heating elements must be performed by carrying out all the steps in the welding cycle, and picture at the end of this chapter. • Equalizing: As shown in the welding cycle, equalizing is the first step, where the twoedges to be welded are located against the heating element at a pressureequal to p1+pt, for the necessary time, with the purpose of creating a uniform internal and external bead (fig. 3). This equalizing step is finished when the bead heights around the entire pipecircumference have reached the values specified in the next...
