Description of basic system
Structure of MLC pipe with outer diameter of 14 - 110 mm
PE-RT Adhesive Adhesive PE-RT Longitudinally welded aluminium
The basic range of Uponor products includes all system components designed for different uses in a variety of applications, e.g. tapwater and radiator connection as well as radiant heating/cooling. Description pipe The Uponor multi-layer composite pipe (MLCP) is a pipe generation that unites the advantages of a plastic and metal pipe and therefore offers a high degree of flexibility and toughness, coupled with high pressure and temperature resistance. The Uponor MLC pipe consists of a longitudinal safety welded aluminium pipe, to which an inner and outer layer of high temperature resistant polyethylene is applied (in accordance with DIN 16833). Owing to the specific form of the octene side chains in the molecular structure of the material, a similar effect is achieved when polyethylene is cross-linked. 50 m
t 50 k
PP
All layers are permanently bounded together by means of an intermediate adhesive layer. A special welding technique guarantees a maximum of safety. The thickness of the aluminium selected for the Uponor MLC pipe is exactly adapted to the compressive strength requirements as well as the bending capability. Smaller dimensions of MLC pipes are designed so that the aluminium layer neutralises the snap-back forces of the plastic material, enabling easier pipe installation with minimal effort. Larger dimensions of MLC pipes and straight lengths of pipes have a greater aluminium layer thickness, making them stiffer and suitable for use as risers. The aluminium pipe is important for heat expansion. Owing to the permanent bond between plastic and aluminium, thermal expansion is determined by the expansion factor of the aluminium and roughly corresponds to that of a metal pipe, i.e. only 1/7th of the expansion of a pure plastic pipe. This offers advantages for pipe installation, since the use of compensating points is largely unnecessary. The smoothness of the inner plastic layer offers water no points of attack. Incrustration and corrosion are prevented in normal use. The transmission of flow noise or noise, e.g. emitted by circulating pumps, is reduced to a minimum due to the specific properties of the raw material.
The most important advantages offered by MLC pipes are: Absolutely diffusion-tight, exceed the requirements of DIN 4726 Hygienicly harmless Minimal roughness k = 0.0004 mm ensuring less pipe friction and lower pressure losses Form stable, by compensation and reduction of snap-back forces Highly flexible, making smaller dimensions (up to 32 x 3 mm) simple to bend by hand or with the corresponding tool Heat expansion similar to that of metals, enabling larger pipe clip distances Clean and easy to install, no welding, soldering, thread cutting or bonding Corrosion-resistant, thanks to its inner and outer plastic layer Excellent long-time rupture strength offers safety in daily use Maximum temperature: 95 °C * Maximum continuous operating pressure: 10 bar at 70 °C continuous operating temperature, with a tested longtime rupture strength of 50 years, safety factor 1.5 * Low weight, easy handling Coils and straight lengths in numerous sizes The DGVW approval permits the use of Uponor MLC pipe for drinking water supply systems according to DIN 1988 TRWI. The approval includes a positive assessment of the material according to the law governing plastic articles for food use in drinking water supply, called KTW recommendation for short.

The Uponor multilayer composite pipe has a length expansion close to metal pipes because of its tight connection between the polyethylene and the aluminium layer. * In case of different parameters please consult Uponor.
Description of basic system System advantages The MLCP installation system offers the following advantages: Certification: MLC pipe and connection systems are approved in numerous countries throughout the world, e.g. Switzerland, Netherlands, Italy, Norway, Poland, Russia, United Kingdom DVGW certification of MLCP system, includes pipes, fittings and Uponor pressing tool General test certificate of the supervising authority (ABP) for MLC pipe penetrations (bulkheads) R 30 to R 90 with ROCKWOOL Conlit shells 150 P/U for the outer diameters 14 to 110 mm. Note: The approvals depend on the level of technology and advances in testing. Detailed information on the current approval status at the various institutes can be provided on request.
Material quality Uponor MLC Pipe: Excellent resistance to internal pressure in long-time stress rupture test, i.e. exceptional long-time rupture strength Maximum service life Quality test (SKZ) Complies with the law governing plastic articles for food use in drinking water supply (KTW recommendation) Low heat expansion Form stability thanks to compensation of snap-back forces Highly flexible Low pipe roughness Installation: Easy, quick and clean installation Only a few tools needed for all applications Easy to use and time saving installation Cold installation without hot water filling, also with tight bending radius Low labour costs The pipe straigthener can be used to straighten offcut sections of MLC pipe (supplied in coils or straight length) with an outer diameter of 14, 16, 18, 20 or 25 mm Easy pressure testing with the pressure test plug

Description of basic system Press fittings The patented MLCP pressing system enables connections to be established within a matter of seconds without welding or soldering. The externally fixed press sleeve, which is permanently connected to the fitting, offers protection against mechanical influences on the
o-rings. The press sleeve has inspection windows to check the insertion depth of the pipe in the fitting before pressing. The plastic stop ring on the shaped aluminium press sleeve simplifies the task of attaching the pressing jaws. The stop rings are colour coded to ensure an optical press marking. After the pressing procedure the
rings fall off. The pressing jaws and the stop rings of the same dimension have been marked with the same colour code. After installation, the connection is capable of ab-sorbing bending forces, due to the form stable press sleeve, without any leakage occurring. After pressing the pipe can be readjusted.

MLC compression fittings press the insert part (2) with fixed closed clamp ring (3) on to the MLC pipe by tightening the swivel nut (1). The compression fitting can be released again; whereas the insert part, made of PPSU, remains permanently connected to the pipe. All ¾ inch compression adapters include eurocone threaded parts.
(2)
Both press and compression fittings are permanently tight as confirmed by SKZ test reports and DVGW certificates.
Quality control Constant quality controls before and during production: Online inspections using special cameras, ball test, spiral test, measurement and tensile test. In the works laboratory: Raw material testing, pipe tests using test piece (peeling test, thickness gauging), pressure and temperature tests and hot storage test. Tests carried out by neutral German and international test institutes.
According to the DVGW worksheet W 542, the minimum long-time rupture strength of multi-layer composite pipes in drinking water distribution systems must be verified over a period of minimum 50 years. For this purpose, an independent test institute performs a number of tests and prepares the resulting internal pressure resistance diagrams.
The aim of these endeavours is to assure the quality of all currently approved MLCP products as well as extending the DVGW approval to new parts, fittings and pipe dimensions in the MLCP range of products.
These values are provided by the SKZ for Uponor MLCP. In addition to further tests, the values shown in the long-time internal pressure diagrams form the basis for the issuance of the DVGW system test mark for MLCP with associated connectors. Together with the test institute and DVGW, Uponor is constantly working on pipe system tests in conformance with the associated worksheets of the DVGW.

Resistance of temperature: Tap water: The maximum permanent operating temperature exists between 0°C and 70°C at a maximum permanent operating pressure of 10 bars*. The short-term malfunction temperature is 95°C of a maximum of 100 hours in the operating lifetime. Heating: The maximum permanent operating temperature is 80°C at a maximum permanent operating pressure of 10 bars*. The short-term malfunction temperature is 95°C of a maximum of 150 hours in the operating time per year. * In some special products the permanent operating pressure is lower than 10 bars. Please have a look on the pipe marking.
In case of exceeding the maximum permanent operating temperatures e.g. in solar systems or district heating systems, the Uponor MLCP system can’t be connected directly to this kind of systems. It has to be ensured that in every situation the maximum limits of use of the Uponor MLCP system are not exceeded. In case of other use of the Uponor MLCP system Uponor has to be consulted.

Where the following are: Δl: Thermal expansion (mm) α: Thermal expansion coefficient (0.025 mm/(m x K)) L: Pipe length (m) Δt: Temperature difference (K)
Distributing and risers For the planning and installation of distributing and rising mains with MLC pipes, in addition to the structural requirements, also thermal expansion aspects must be taken into account.
Exposed MLC pipes fully exposed to thermal expansion, must be provided with appropriate expansion compensation. For this purpose, a knowledge of the position of all fixed points is necessary. Compensation always takes place between two fixed points (FP) and directional changes (bending leg BS).

Pressure test with water for tap water pipes
Pressure test with water for tap water pipes
Note: The chapter “Pressure test of tap water installations” in the actual technical manual “MLCP system for tap water installation and radiator connection” is to be followed. Construction project:
Stage: Person carrying out the test: Test pressure = max. permissible operating pressure + 5 bar ≤ 15 bar (related to the lowest point of the system) All tanks, equipment and fittings, e.g. safety valve and expansion tanks, which are not suitable for the pressure test, must be removed from the system during the test period. The system is filled with filtered water and completely vented. A visual inspection of the pipe joints must be made during the test. After the test pressure has been reached a suitable time must elapse to allow for temperature equalisation between the ambient temperature and the temperature of the fill water. If necessary, the test pressure must be re-established after the waiting period.

Pressure test report for the radiator installation MASTER
Note: The chapter “Pressure test of radiator installations” in the actual technical manual “MLCP system for tap water installation and radiator connection” is to be followed
Pressure test report for radiator connection
Construction project:
Stage: Person carrying out the test:
maximum permissible operating pressure (in relation to the lowest point of the system). System altitude:
bar
m
Design parameter – Supply temperature:
°C
– Return temperature:
°C
After the test pressure has been reached, a suitable time must elapse to allow for temperature equalisation between the ambient temperature and the temperature of the fill water. If necessary, the test pressure must be re-established after the waiting period. All tanks, equipment and fittings, e.g. safety valve and expansion tanks, which are not suitable for the pressure test, must be removed from the system during the test period. The system is filled with filtered water and completely vented. During the test a visual inspection of the pipe connections must be made.

The system specified above was heated to the design temperatures on and no leakage was found There was also no leakage found after the cooling. With frost danger suitable measures are to be taken (e.g. use of antifreeze, heating of the building). If no freeze protection is required for the intended system use, the antifreeze is to be removed by emptying and flushing the system with at least 3 water changes. Antifreeze was added to the water: Drainage as stated above:
