GENERAL INFORMATION ON CROSS LINKED POLYETHYLENE 02

02_03

All aforementioned methods achieve the same results in PE-X pipes and meet the DIN 16892/16893 and the recent European EN ISO 15875-1/2 standards. Their only difference lies in the cross-linking degree specified in the DIN and EN standards. 70% for method –a, 65% for method –b, and -60% for method –c. For example, a pipe with a cross-linking degree of 68% that has been produced using method –a does not meet the specifications, while a pipe with the same cross-linking degree produced by method –b does. The Como-pex pipes of Interplast are produced using the –b method. It is a method that has managed to improve the characteristics of Pex pipes since the fact that cross-linking degree continues over time, which is considered as a huge advantage, leading as such to exceptional properties of the product during its use. Furthermore, -b method pipes, in varying degrees of cross-linking, are more homogenous in their behavior.

The applications of plastic pipes are so common in our daily life that these types of pipes have come to replace conven- tional pipes on a large scale. One of the most important breakthroughs is their use in hot water networks. The raw materials used are polypropylene (PP) and cross-linked polyethylene (PE-X) produced from a special composition of high density polyethylene (HDPE). In HDPE, a reaction is induced in the double bonds, so that many of them get connected and by the help of silane molecules, a three-dimensional homogenous network is created of high molecular weight. The final product (cross- linked polyethylene) has excellent performance at high temperatures combined with high pressures, has improved resistance to impact and to chemicals and has a longer lifespan. Today, 40 years after their first applications and based on their successful history, Pex pipes are constantly growing in demand gaining a significant market share.

Characteristic is the ever increasing demand of method –b in the markets, with ever increasing trends in the recent years compared to cross-linked manufactured products of the other alternatives.

Como-pex pipes are manufactured in white and in black if they are to be used under continuous exposure to solar radiation. Upon request, they can also be produced in blue or gray color. Como-pex pipes are delivered in 100m coils and in 50m coils for diameters 28 and 32mm. Straight lengths or longer coils can be produced according to the needs of the customer. Como-pex pipes bear a marking per meter, indicating the brand, the outer diameter, the cross-linking method, the wall thickness, the specifications under which the pipes are produced and controlled (EN, DIN), the institutes and bodies having certified the pipes (SKZ, AENOR, CSA, MPA-NRW, WRAS), the operating pressure at 20oC and 95oC, their class defining the fields of application and a lot number that indicates the date and time of production. The coils are packed in cardboard boxes bearing a printing with the pipe’s brand name and its characteristics (outer diameter, wall thickness, color and certificates).

It is recommended that the white colored pipes be kept in their cartons until the time of installation.

The following table shows some of the main characteristics of Como-pex pipes.

These characteristics have resulted from lifespan diagrams in conjunction with various tests.

- Oxygen barrier pipes have higher mechanical strengths than ordinary Pex pipes, as the two additional layers that are 0,15mm thick add extra material. For example, ordinary Pex pipes should have a minimum outer diameter of 16mm and minimum wall thickness of 2.00mm to meet DIN 16892. The oxygen barrier pipe should have a minimum outer diameter of 16.3mm and minimum wall thickness of 2.15mm to meet DIN 16892 (mechanical strength) and DIN 4726 (which defines oxygen diffusion). - Present lower linear heat reversion. Laboratory tests have shown that Como-pex pipe specimens at 120°C present 0,8 % heat reversion (with a limit according to DIN being at 3%). Como-pex Oxygen barrier pipes present 0.5% heat reversion. For all the aforementioned reasons, Pex pipes with oxygen barrier are used in all applications all over the countries of Northern Europe.

Como-pex Oxygen Barrier

Particularly for central heating and underfloor heating installa- tions (closed circuits), Interplast manufactures Cross Linked Polyethylene pipe with an oxygen barrier.

The Como-pex Oxygen Barrier pipe consists of 3 layers:

-Inner layer of Cross Linked Polyethylene -Bonding layer for better adhesion of EVOH to the main pipe -Oxygen Barrier layer (EVOH-ethylene vinyl alcohol polymer)

The additional properties, as compared to ordinary Pex pipe, are analyzed below:

- The special oxygen barrier prevents oxygen and other gases from entering the closed heating circuit through the pipe and corroding the metal components of the system (e.g. radiators, boiler, valves etc). In the case of underfloor heating, where the circuits are quite long, it is considered as a must.

The main characteristics of Como-pex oxygen Barrier pipe are shown in the following table.

* On demand

For the convenience of the installer, Como pex Oxygen Barrier pipe is also available inside corrugated piping.

Due to the differences between nominal and actual dimen- sions, certain brass fittings do not join well the plastic pipe.

Interplast manufactures brass fittings that join equally well on ordinary Pex and Como-pex Oxygen Barrier pipe. Pipes with an outside diameter of 17mm are also available in 600m coils and can be fitted on a special unwinder for underfloor heating applications.

CERTIFICATES 08

18_19

Como-pex pipes meet and exceed the specifications set by the International ISO standards, the European Norms, the internationally accepted German DIN, the Spanish UNE, and the British BS standards. This results to that Como-pex pipes have not presented a single failure in the regular biannual tests carried out by the official institutes and bodies on random samples taken from the production and the warehouse. The outcome of the above is that Como-pex has been certified as a final product by the following organizations:

- EN ISO 9001:2008 by TÜV Germany for compliance with all international specifications pertaining to Como-pex.

- SKZ Germany, AENOR Spain, CSA Canada, GOST Russia, ZIK Croatia, for the physical and mechanical proper- ties of the pipe. The procedure concerns checking the dimensions of the pipe, determining the degree of cross- linking, microscopical material homogeneity assessment, hydrostatic pressure testing at various temperatures, melt flow rate testing and testing of the longitudinal heat reversion. - MPA-NRW Germany for oxygen permeability testing of Como-pex Oxygen Barrier pipes. It concerns a measurement that should comply with DIN 4726. - WRAS-NSF Great Britain for the suitability of Como-pex pipes for drinking water. It concerns tests carried out at 20°C and 80°C on taste, odor, development of microorganisms, extraction of substances and metals dangerous for public health (cadmium, arsenic etc.) Furthermore, the pipes are also controlled by ELOT (Greek Organization for Standardization-Laboratory of polymers) in hydrostatic pressure testing at 110°C and by the State General Chemical Laboratory for suitability for drinking water.

PRESSURE LOSSES 09

As a result of this characteristic, the pressure losses on the pipeline sections present low values, facilitating the design calculations and rendering installations more economical by the use of pipes with smaller dimensions and pumps of lower power for the same requirements of water supply. The installation operates quietly and smoothly, allowing the possibility to use, where needed, faster water velocities, without having to worry about the noise levels or the vibrations of the pipes during operation. The diagram illustrates the curves calculated for water temperature at 80°C. For ø 16x2.0 pipe and a flow rate of Q=140l/h, the flow velocity is V = 0.37m/sec and the loss of head is equal to R = 17mmH20/m. However, since we have calculated the diagram for a water temperature of 80°C (central heating), we have to divide the R= 17mm value by a correction factor (Fc), if we want to calculate the loss at a water temperature of 25°C (plumbing installation). The correction factor is provided in the following diagram and in our example equals to 0.935.

Cross-linked PE pipes present an exceptionally smooth inner surface, resulting in a very low roughness factor (0.006mm), which compared to other pipe types, even copper (κ=0.014 mm), is much reduced. The surface of every solid material, no matter how smooth it may look, still presents some level of roughness. The level of this roughness is quantitatively expressed by a characteristic length, e, which is called absolute roughness of the surface. The length e is equal to the statistical mean of the heights of the recesses and the projections of the surface on a large (compared to their size) area. The value of e depends on the construction material and the processing of the inner walls of the pipe. Corrosion and depositions increase roughness. Since the inner diameter also plays a role on the influence of the pressure drop, in order to decide whether the roughness is negligible or not, we use the ratio e/d that is called relative roughness.

The roughness coefficient, n, is used in hydraulic calculations and is calculated by Manning’s formula:

n = [R2/3xS1/2] / V

Therefore, R = 17/0,935 = 18,18mm H2O/m, which is the true value (loss of head) at 25°C.

where

With the help of the equivalent Pa/m (1000 Pa = 0,01 Bar), the press loss converted to Bar in the specific example is 18,18/10000 = 0,001818 Bar/m.

R = hydraulic radius, S = the slope of the pipeline, V = flow velocity

The roughness coefficient depends from the material of the pipe, but also from other factors such as bad connections, bad lining, etc.

In this diagram, it is quite simple to determine the loss of head when all other parameters are known, e.g.:

R = loss of head value in mm Η 2 Ο V = water velocity in m/s Q = flow rate value in l/h L = pipe length to be calculated in m.

Pipe extractor Special metal component that enables us to replace the plastic pipes in case of failure. There are two bolts with threading in their bodies and a specially shaped head with perforations in the center from which a wire passes and ends at both ends. The two bolts are placed back-to-back. The set includes two rings. Usage On the pipe that we want to replace, we firstly pass the ring and then tighten one bolt to the inner diameter of the pipe until it stops at the end. We do the exact same thing to the new pipe by tightening the other end. After this we can pull the problematic pipe from its other end and by pulling it into its place it will penetrate into the new pipe. Production material is st 37 – 2 (370 Kp/mm2)

ΕLVIOM Brass Fittings All brass bars processed by ELVIOM conform to the European standards ΕΝ 12164, ΕΝ 12165, ΕΝ 12167 and ΕΝ 12168. All incoming materials are subject to dimensional control by instruments and devices, hardness tests with a last generation stable hardness tester and controls of chemical analysis of the alloy composition with a privately-owned mass spectrograph. The dimensions of the design are strictly applied during the

manufacturing of the components. The threads of the components are manufactured according to the European standards ΕΝ ISO 228 and

They are produced by copper alloy CW617N and exceed the German standards. Raw material has undergone a special thermal processing in order to obtain the desirable hardness of raw material. Within the product, during its processing, an internal stress is developed, thus increasing its hardness. The final product is subject now, for a second time to thermal processing , eliminating the stresses that have been developed during processing, thus nullifying the possibilities of season cracking and restoring the desirable hardness.

EN ISO 7(DIN2999) and their control is carried out by thread controllers. All brass fittings are designed to meet the needs and demands of consumers and to be able to easily and effectively be applied by the installers.
