HEATING & SANITARY

Quad PipeThe quad combines 4 pipes, two for use with flow and return heating pipework, one for use with a hot water flow and second hot water pipe for the secondary circulation loop.

The internal corrosion-resistant pipes are cross-linked PE-Xa (in accordance with DIN 16892/16893), with a red oxygen barrier included for the heating pipes (EVOH barrier in accordance with DIN 7426).

The internal foam that supports and insulates the pipework is a CFC-free foam made from cross-linked PE-X with closed microcellular structure and has a minimal water absorption capacity of <1% (in accordance with DIN 53428). In the centre of the 4 pipes is a PE-X centre piece which guarantees an effective separation between flow, return, hot water and circulation pipes. A corrugated outer casing in PE-HD ensures protection to the piping system whilst allowing maximum flexibility.

The quad pipe system offers the following benefits:

• 4 pipes in 1 – Saves money on materials

• Reduce trench size which reduces excavation costs

• One pipe to lay thus reducing labour costs

• Internal connections in one position

• Flexible solution offers a fast installation

• Pipe cut to size (minimum length 10m, maximum length 100m)

• No specialist tools required for installation

AXIAL PRESS FITTINGS

Axial Press Fittings

As an alternative to compression fittings, Maincor offer a full range of axial press fittings for joining Pipe and making building connections.

The fittings are made of CW617N-Dw brass and require tooling to first expand the pipe and then slide the metal retaining sleeve onto the pipe and fitting.

Tooling can be hired via various National tool hire companies or alternatively, for regular users, Maincor can supply the tooling. Fittings are available for 6 bar Pipes and a compression sleeve is required for each axial press connection onto the PEX pipe.

A full range of tee’s, couplers and elbows are also available for AustroPUR Heating 6 bar.

Axial Press Fittings - Guidance On Use Freezing Conditions

Water supply systems must be installed in a location and/ or with sufficient insulation to ensure that they do not freeze at any time. Freezing of a water supply line can damage the pipe, fittings, valves, parts, and cause water damage.

Corrosion

The internal PEX pipes are widened by the expanding tool prior to inserting the fitting. The average flow of the fittings is adapted to the average flow of the pipe which results in a constant flow, a reduced noise emission and a better erosion resistance.

Corrosion can damage brass plumbing fittings, which should therefore be protected with suitable material if they come into contact with such materials as masonry, rendering, or cement.

Non-Detachable Joint

Once the fitting is made, the axial press fitting is non-demountable.

The basis of this jointing technique is the so-called ‘memory-effect’ of the elastic shape recovery of the PEX pipe. The compression sleeve is pushed over the pipe with the inside chamfer pointing to the end of the pipe. The pipe is then cold expanded and pushed onto the fitting. The elastic shape recovery of the expanded pipe starts, thanks to which the expanded diameter of the PEX pipe becomes smaller again and the fitting starts to clamp. The joint must always be made by a compatible tool for compression sleeve joints. After expanding and mounting onto the fitting, a space results between the pipe and the fitting before pressing on the sleeve. The maximum space between the pipe and fitting is as follows:

Space between pipe and fitting

Material

Fittings are made from CW617-Dw (low lead) brass. This brass is approved for drinking water consumption by the European community, and the forged fittings with CW617N-Dw gives a very reliable quality with excellent and stable material specs.

Threads

Where multiple properties are connected via a series of pipes and tee fittings, connections will be made using the axial press fittings. At points where pipes terminate, axial press to threaded fittings are required. When sealing threads, only use materials for the intended purpose (thread sealant, hemp and putty) suitable for use with plastic pipes. Packing material must not be overused, and hemp and putty must be used with particular care. Proportion the amount of packing material to the size of the threads. The general rule is that the crests of the threads should be left exposed. Please also note that hemp swells when it gets wet. Make sure that the size, lengths, and tolerances of the threads to be joined are compatible with each other and all joints must be protected.

When using thread sealant the entire length of the threads of the parts to be joined must be used and they must be tightened adequately. The joint must never rely upon sealant alone. ISO7 (British Standard Pipe Taper thread, BSPT) has a conical (tapered) thread and is marked with the letter R.

Material Stresses

Excessive material stress can damage joints. Do not overtighten threaded connections. Use tools suitable for installation and adjust the size of the tool to the size of the joint. Open-jawed spanners are recommended as tools. If you are using a pipe wrench or a vice, be careful not to squeeze too hard. Pipelines and structures must have sufficient support to ensure that no tension remains or is formed.

Pressure Test and Rinsing

Water systems and/or installed components must be rinsed thoroughly with domestic water, and pressure tested, as well as visually inspected, prior to any covering and deployment. Please refer to the appendix for pressure and commissioning details.

Axial Press Fittings Installation

1. Remove the outer casing and insulation and ensure

the pipes are clean.

Prior to making a connection, where pipes terminate, place the end cap over the pipe as shown or if insulation sets are being used, place the correct sealing ring around the pipe.

2. Place the Compression Sleeve over the pipe and ensure that the sleeve orientation is as shown in the photo above. It is essential the two engraved lines on the Compression Sleeve are at the furthest point from the end of the pipe so that the square end faces the insulation and the chamfered edge faces towards the end of the pipe.

3. With the Compression Sleeve slid well back from the pipe end, expand the pipe using the expansion tool. After expanding the pipe once, rotate the tool by 30° and expand the pipe again.

Ensure that sealing rings are already on the Pipe before joining pipes.

4. After expanding the pipe, quickly insert the fitting

body into the pipe. There will be a gap between the end of the pipe and the fitting and this is normal. On the previous page, the maximum space between the pipe and fitting for various pipe sizes is shown.

5. Using the clamping tool and appropriately sized clamping attachment, press the Compression Sleeve onto the pipe and fitting body. The press machine can be mounted in either direction when making the connection.

6. The fitting is now complete.

LONG TIME BEHAVIOUR

Period of time - inner pressure resistance Allowable working pressure according to DIN 16892/93 based on the flow medium water and

are calculated with a safety factor of 1.25 (in accordance with DIN EN ISO 12162). The values are monitored by long-term studies and tested and confirmed by independent test institutes in different countries. The maximum operating temperature is set at 95°C, but a temporary overheating (malfunction temperature) of 110°C is taken into account. The pressure and temperature limits of the pipes depends on the combination of pressure, temperature and time. These technical data are determined in accordance with DIN 16892/93 and can only give a general statement on the long-term rupture strength, because the maximum temperature and pressure in the concrete application can vary widely.

INSTALLATION GUIDELINES

23www.maincor.co.uk

INSTALLATION GUIDELINES

Groundwork and laying of the pipe AustroPUR pipes are laid in trenches in the ground.

The following guidelines should be followed during pipe installation:

• Lay the pipes in a bed of sand (min. 10 cm); grain size 0-4mm.

• Avoid damaging the casing, remove sharp objects from the trench.

• Always grasp the transport pipe and not the outer casing.

• Only use pulling and lift assistance which does not harm the outer casing.

• Keep to the stated bending radiuses.

• Lay the line in a serpentine course.

• The code of good craftsmanship for installing underground pipes must be observed. Read our installation instructions.

• Sketch how and where the pipe network runs on a plan (including branches and connections), this plan should be kept in your records.

If possible put the soil on one side of the trench. The following steps can be performed from the other side:

• Position the coil alongside the trench.

• Remove the packaging foil.

• Place the end of the pipe in position.

• Cut the straps layer after layer during the roll-off.

• Roll the pipe alongside or straight into the trench.

• Apply the rubber end caps or shrink caps.

• Connect your pipes with couplings.

• Conduct the pressure test - fill in the report

• Fill the trench with the first sand layer (min 10 cm).

• Apply the warning tape

• Fill in the trench with the soil from the side.

Our pre-insulated pipes as well as our longitudinal, elbow- and T-insulation kits are suitable for the stress caused by heavy goods vehicles SLW 60 under defined installation conditions according to ATV DVWK-A127. The laying of the pipe must be carried out in accordance with the currently applicable guidelines DWA-A127 for underground pipes.

PRESSURE TEST

Pressure TestThe pressure test procedure is obligatory before closing the trench!Leak-tightness testing with water:1. Pipes must be accessible and must not be covered.

2. Dismantle safety and counting devices where required and replace with pipe pieces or pipe end stops.

3. Fill pipes from the deepest point of the system, excluding any air, with filtered drinking water. Here the water temperature must match the ambient temperature (Δ ϑ ≤ 10 K ambient temperature to water temperature)

4. Bleed the draw-off points until no air can be determined in the expelled water.

5. Use a pressure testing device with an accuracy of 100 hPa (0.1 bar) for the pressure test.

6. Connect the pressure testing device at the deepest point of the heating network system.

7. Carefully close all draw-off points.

8. Make sure that the temperature remains as constant as possible during the pressure test.

9. Prepare the pressure test record sheet and note the system data.

The filling water is filtered and the pipesystem is without any air. The allowable working pressure is:_______ bar

Water temperature ϑW =_______ °C Ambient temperature ϑA=_______ °C Δϑ = ϑA –ϑW = _______K

2. Pressure test

Step 1:

Δϑ ≤ 10 K between ambient temperature and water temperature

Test pressure: _______ bar (1,1 x max. working pressure) Waiting time: _______ min. (minimum 30 minutes); hold test pressure, repressurise when necessary.

Pressure after 30 min.: _______ bar

The whole installation, especially the connections, are checked and no leaks are detected.

Step 2: Test pressure: _______ bar (0,5 x max. test pressure) Test time: _______ min. (120 min.) Pressure after 120 min.:_______ bar

The whole installation, especially the connections, are checked and no leaks are detected.

3. Check notes At step 2 of the pressure test no pressure loss at the

manometer was detected.

The whole installation is sealed.

4. Confirmation For the client:

For the Contractor:

Attachment:

Pressure test for system with PE-Xa-pipes:1. Build up the test pressure (= 1.1 x max. operating pressure)

slowly in the installation.

2. Maintain the test pressure for 30 minutes. Build up the test pressure again where necessary.

3. Note down the test pressure in the pressure test record after 30 minutes.

4. Verify the leaktightness of the entire installation, particularly the connecting points, by means of a visual inspection.

5. Slowly reduce the test pressure to 0.5 x maximum test pressure and note down the test pressure in the pressure test report.

6. Read the test pressure after 2 hours and note it down in the pressure test record.

7. Verify the leaktightness of the entire installation, particularly the connecting points, by means of a visual inspection.

8. If the test pressure drops away: -Carry out another precise visual inspection of the pipes, draw-off points and connecting points. -After rectifying the cause of the drop in pressure repeat the pressure test on the system (steps 1-7).

9. If no leaks have been found during the visual inspection the leaktightness test can be concluded.

Concluding the pressure test with water Following conclusion of the pressure test:1. The company that performed the test and the client must

confirm the pressure test in the pressure test record.

2. Remove the pressure test device.

3. Re-attach the removed safety and metering equipment.
