2- Technical Properties Of Pilsa Aluminium Foiled Pipe


PIPES IS CUT Welding machine is heated up to 260 °C. When the control light is switched off, (at 260 °C) welding process is started. Pipes should be cut at appropiate lenght perpendicular to the pipe center. Welding distance should be market from the pipe.	IF IT IS ALUMINIUM FOILED PIPE... A special shaver is used to take off the PP-R layer and Aluminium Foil.

PIPE AND FITTINGS ARE HATED... Joining surface of pipes and fittings should be clean. If necessary, welding parts should be cleaned with alcohol and should be dried with a dry cloth. During welding, neither th epipe nor the fittings should be moved. Duration of heating should be determined as shown in Table 3.	AND ARE JOINED NOT BE SEPERATED AGAIN... Pipes and fittings should be heated simultaneously after process ends, they should be taken out quickly and without turning they should be joined by pressing one to another axially. Welding machines should be cleaned after every operation for the next use.

Technical Properties Of Pilsa Aluminium Foiled Pipe

*Raw Material:PP-R and Aluminium foil.
*Ideal for central heatinğ and plumbing systems.
*Sound resistant.
*Resistance to acids and cholorine
*Never deflects under heat, minimum strecthing.
*Pressure tolerance:for water at 20°C 20 bars, for water at 90 °C 10 bars.
*İt is easy to scrape the outer surface and aluminium foil by a simple fusion welding.
*Because of the plastic property, the pipes are light and plumbing is easy. This saves a considerable amount of time, labour and transportation.

Example :
Temperature Disparity (Δt) = 40 K
Length of pipe (L) = 5m
Amount of extension (ΔL) = 1.4 mm / mx 5,0 m = 7 m

Calculation Of Thermal Expansion

When PP-R pipe is subjected to a temperature difference, the length of pipe changes in longitudinal direction. The thermal coefficients of linear expansion at different temperatures are shown in table below:

LİNEER EXPANSION ELONGATION

Temperature Difference	Test Method	Unit	Coefficient	Elongation per meter
-30°C-0°C	ASTM D 696-44	1/°C	0,65E-4	0,2 cm
0°C-30°C	ASTM D 696-44	1/°C	1,05E-4	0,3 cm
30°C-60°C	ASTM D 696-44	1/°C	1,40E-4	0,4 cm
60°C-90°C	ASTM D 696-44	1/°C	1,70E-4	0,5 cm

Horizontal pipes conveying hot liquids must be straddled at intervals not exceeding one meter. The pipe must freely move on the straddled. Vertical pipes should be fixed at the top end, if possible, left free at the lower end.
Example: When the temperature rises from 0°C to 90°C, one meter pipe elongates. 0.3+0.4+0.5=1.2 cm.

Plumbing / Design

PP-R pipes installed in the same way as conventional galvanized metal pipes. Howewer special attention should be paid to the higher expansion rate of PP-R pipes compared to the metal pipes. Pipes can be installed in/on the wall. Since the weights of the PP-R pipes and fittings are about one ninth of the metal pipes, installation of PP-R pipes is easier, adjusment for expansion can be done in one direction. Howewer, one should make it certain that pipes move frelly in axial direction. If the expansion can be done in one direction. Howewer, one should make it certain that pipes move freely
in axial direction U bend or OMEGA compensators should be added to the design. Fixed supports and sliding supports should be chosen in such a way that they do not damage the outer surface of the pipe.

Expansion pipe segments can be produced during the installation. Four elbows and length of pipe are usually sufficient to do this. The pipe length, necessary for free bend (Ls) is calculated by using the formula; Ls= C√d ΔL where,
Ls= free bend length in mm.
d= outer diameter of the pipe in mm.
L= elongation in mm.
C= material coefficient (3 for PP-R)

Table2

Table3

Fixed Support

Fixed supports are used to fix the pipe at certain points against undesired pipe movements. Fixed supports should be stronger compared to the sliding supports. Fittings are used to construct fixed supports. At the points where direction changes, fixed supports should not be used. The distance between the fixed supports should be chose in such a way that pipe elongation is not effected. In general elongation of the pipes is provided by free bending section. Figure 4 and 5 show the effect of elongation and how it is handled in the system.

Figure7 Figure 8

In some casses pipes are bent by heating. Howewer, pipes should never be allowed to contact to flame, instead heatinğ should be carried out by blowing air. A temperature of 140°C is sufficient to bend the pipes. Recommended radius of curvatures are shown in Table 5. The distance between the two clips in horizontal pipes depends on the factors such as the raw material that pipe is procudet from, wall thickness, weight of the pipe and temperature. The 5 shows recommended distances between the clips. Practically, same distances can be used for vertical systems.

During installation of pipes from the main line to apartmens in a building one of following techniques are used to allow the pipes expand linearly.

APPLICATIONS IN THE MAIN CHIMNEY

Tesisat bacasındaki kolon borusundan daire girişlerindeki bağlantılar yapılırken daha sonra borular lineer olarak genleşebileceği için aşağıdaki tekniklerden biri kullanılarak önlem alınmalıdır.

Figure7A: Distance ''a'' between the tee and wall hole should be provided.
Figure 7B: The hole diameter inside the wall should be bigger than the pipe diameter which crosses
the wall.
Figure 7C: L shapen pipe segments is used.

ASSEMBLY OF PIPE AND FITTINGS

Beside the raw material of the pipe, the reliability of plumbing systems depends on the fittings and how they are joined. Since the pipes and fittings are produced from the same material, connections which are usually homogeneous:
There are two main coonections:
a) Thereaded connections: Same as in galvanized pipes
b) Fusion welding:
1) Welding done by heating outer surface of the pipe and inner surface of the fitting.
2) Electrofusion welding.
Since the electrofusion technique is quite expensive, socket welding is commonly used. When a tensile test is appliedto the welded pipe and fitting segment, it is absorverd that welding points

are not effected even when the pipe segment reaches of the fracture point. These welded parts are as strong as the pipe itself.

APPLICATION OF SOCKET WELDING

1-Preparation of welding:
Both ends of pipes are cut as perpendicularly to the pipe axis in required length. Chamfers should be given to the outer ends of the pipe by a knife. Parts to be welded should be cleaned by alcohol and dried by clean fabric or paper before welding. Socket depth (welding distance) is marked from the end of the pipe. Temperature is adjusted to 260 (+) 10°C in the welding machine. Turning off red light on the welding machine indicates that welding temperature is reached. Heaters in the welding machine should always be kept clean.
2-Welding:
Pipes and fitting are pushed axially towards the heaters of the welding machine. Then they are pulled out simultaneously and joined to each other in axial direction. During this, the operation pipe never should be turned radially. After welding heaters should be cleaned be cleaned for the next use.
