IIL PPRC Pipes & Fittings Applications
07 08
1. Simple Installation: IIL PPRC Pipes and Fittings includes a complete system of pipes and fittings that can be joined by fusion welding using IIL PPRC welding machines and socket molds. The pipes are easily assembled on site using the instructions and techniques recommended in this catalogue.
2. Pressure Stability: According to DIN Standards, IIL PPRC Pipes and Fittings are tested in 3 standard pressure / temperature / time combinations, or other combinations according to DIN Standard tables. The following table signifies the standard tests:
3. Chemical and Corrosion Resistance:Due to the properties of polypropylene materials, and the brass grade with chromium protection, IIL PPRC pipes and fittings are corrosion and chemical resistant, especially as compared to metallic pipes.
4. Environmentally Friendly:IIL PPRC Pipes and Fittings are completely environmentally friendly. Polypropylene (PP-R) contains no toxic materials that may be hazardous to the environment. Moreover, PP-R emits no waste in its production process. PP-R is commonly and completely recyclable, and can be recycled to be used in other grade products multiple times.
5. Flow Properties:Due to the smooth internal diameters of the pipes as well as the accurate alignment of transition parts of system components, there is little pressure drop in the IIL PPRC system compared to other traditional piping systems. 6. Sound Properties:A significant advantage of IIL PPRC Pipes and Fittings system is the low noise generated by the network of pipes and fittings throughout the building as compared with the other piping systems. This is due to the properties of the polypropylene material in dampening the sound, in addition to the thickness of pipes and fitting. Following IIL PPRC guidelines further reduces the noise levels and improves the system.
7. Hygienic Properties:IIL PPRC system demonstrates exceptional hygienic properties. Neither taste nor smell nor any toxicity is experienced in the installed systems. Moreover, and due to the food grade coloring of full system components, bacterial growth is virtually illuminated due to the opaqueness of the components, preventing sunlight penetration which enhances bacterial growth.
8. Service Life:The service life of IIL PPRC Pipes and Fittings depend on the pressure, temperature and pipe pressure rating. Table A3 details the relationship between pressure, temperature and service life.

WeldingIIL PPRC System can be easily welded together using IIL welding machines and tools in a quick and convenient manner by fusing the fitting sockets into the pipes with heating and applying quick manual pressure. The following guidelines are given to illustrate how this can be done in a thorough and professional manner, to result in a reliable network that will yield years of trouble free service.
Step 1.Cut Pipe into the required length using a cutter, mark the welding depth on the pipe, ensure that the indicator light on the welding tool signals that the tools is hot enough (260 °C) for welding.
Step 2.Push the pipe and fitting into the welding adaptors, applying even strength on both ends. Do not twist or turn the pipe and fitting while pushing. Wait until heating time is reached.
13 14
Step 3.When the heating time is reached, remove both pipe and fitting together without twisting or turning while pulling out of the welding adaptor. Immediately push both pipe and fitting together until the depth is reached. It is possible to adjust the joints angle by more than 5 degrees during this time. Joint is now completed.
Proper clamping of IIL PPRC system in the installations is critical in ensuring a problem-free service life. The installation usually is comprised of fixed and sliding clamps, which will allow the pipe network to flex and bend without affecting the integrity of the network. Fixed Clamps: Used where clamps hold the pipes in a fixed position. Sliding Clamps: Used where the pipe is allowed to slide for linear expansion. Recommended Clamping Distances:

Linear ExpansionIt is always advised to take linear expansion into account the design of the piping network.The Linear expansion of IIL Pipes depends on the difference of operating and installation temperatures.∆T (K)= T operating Temperature. T installation temperature
Linear Expansion (∆L) is calculated as follows:∆L = ∆TxLxαL=Length of Pipe α=Coefficient of Expansion
The following table gives the expansion (mm) in different length and temperature difference.
Fusion Time TableThe Table below provides the necessary information for a good welding joint for various IIL PPRC Pipe sizes.
Note:1. Heating time start when both pipe and fitting is pushed into correct depth.2. Welding time begins when joints are connected.3. Cooling time is taken for the joint to be completely cured.
*Warning:Never reduce cooling time by pouring water or by other means.

WEL= 2xL+SL and LBL=KxdxL
where ΔL=Linear Expansion in mm
SL=Safety Length (150 mm)
