3.5 MARKINGS

All carbon steel press fittings are marked with Frabo logo.

They are also provided with a red mark, featuring a banned tap, to indicate they are NOT suitable for potable water.

NOT FOR POTABLE WATER: this means that the tubes used with carbon-steel fittings are not suitable for household water applications.

FRABOPRESS C-STEEL SECURFRABO M fittings also have the red SECURFRABO symbol as they are equipped with the SECURFRABO safety system, which allows any un-pressed fittings to be detected. The SECURFRABO system is made using an elastomeric gasket whose patented shape allows liquid to leak out if the junction has not been pressed.

3.6 SUITABLE PIPES

Pipes available for FRABOPRESS C-STEEL SECURFRABO M and FRABOPRESS C-STEEL BIG SIZE system are carbon steel pipe, galvanized internally and externally, or only externally, electrically welded. Non-destructive test on 100% of the pipes with induced-current methods according to UNI EN ISO 10893 standard are performed during the production process to ensure tightness.

4. COMPATIBLE INSTALLATION TOOLSThe pressing of the fittings is to be carried out with a suitable tool and with a correctly maintained pressing jaw, in order to achieve an indissoluble cold junction, resistant to torsion, and a hydraulic seal guaranteed by the O-ring. All Jaws and slings must be for “M” Profile Fittings.

It is not the purpose of the training to give instruction on the use of the tools required for installation. There is a wide range of tool types and manufacturers suitable for the installation of Press Fitting Tube systems, and it is the installers responsibility to ensure suitability and familiarity with the operation of the tools chosen. You should always consult your chosen tool supplier and / or instruction manual to ensure suitability.

A guide to press fitting tools can be found on Frabo website www.frabo.com . For any additional information you can contact FRABO technical support office.

Mark the insertion (socket) depth of the fitting onto the tube.

Insert the correctly sized jaws into the press-fit tool and place them over the bead at the mouth of the fitting.

Press the trigger or button to start the jointing cycle. A 90° angle between the tube and jaws must be maintained when pressing. When the jaws have fully enclosed the mouth of the fitting the joint is complete. The jaw should be released from around the fitting.

SpacingAllow sufficient clearance around each fitting to allow press-fit jaws to be attached without hindrance. For clipping distances see page 17.

Health and SafetyWe recommend that eye protection is worn when operating all press-fit tools.Do not activate a press-fit tool without a fitting in the jaws.

Select the appropriate size sling jaw and place it across the fitting.

Attach the appropriate adaptor to the press tool and connect it to the sling jaw. A 90° angle between the tube and the sling jaw must be maintained when pressing. Commence the pressing operation by pressing the trigger or button.

108mm second press For 108mm the sling jaw should be left in place and the second adaptor attached. Re-check to ensure the tube is still fully inserted and repeat the pressing operation to complete the procedure. The 108mm joint is not fully made until the fitting has been through two pressing operations.

After pressing open the adaptor and remove it from the chain.

Lubricant The use of dri-slide lubricant is required when pressing big size fittings. The pressing profile of the slings should be cleaned and lubricated every 50 joints for 42mm to 76 mm sizes, and every 5 joints for 89 and 108mm sizes. Sling segments, arms and pivots should be kept lubricated. Avoid any contact between the lubricant and the O-ring.

Spacing Allow sufficient clearance around each fitting to allow press-fit jaws to be attached without hindrance. For clipping distances see page 17.

Health and SafetyWe recommend that eye protection is worn when operating all press-fit tools. Do not activate a press-fit tool without a fitting in the jaws.

5.3 TECHNICAL SOLUTIONS FOR INSTALLATION AND ASSEMBLY

1. HANDLING & STORAGE OF MATERIALS and PRE-INSTALLATION CHECKSCare should be taken always with handling & storing materials to ensure that no damage is caused to either tube or fittings. Attention should be made to the cleanliness of fittings, and where possible they should not be removed from packaging until required in order to prevent contamination from dirt or harmful substances. Take care when removing pipes from packing. The use of blades or sharp tools to cut packing can cause scratching which will not be sealed by the O-Rings. Prior to any installation, ensure that the materials selected are compatible with the requirements of the application and environment. Ensure that any pipe, fittings and O-Rings to be used are in good condition with no visible damage or contamination.

2. CUTTING THE PIPEPipe should always be cut squarely using tools or methods which do not affect the structure & integrity of the material. We would advise as a preference to use tube cutting tools which are non-abrasive, such as wheel cutters, so as to avoid heat generation caused by friction cutting methods such as abrasive discs. Excessive heat generation can cause damage to the integrity of the tube.

3. DEBURRING THE PIPEFollowing cutting, the pipe MUST be de-burred both externally and internally to prevent damage to the fitting O-Rings. This operation is necessary whenever the adopted cutting system can create burrs; for example, with manual and electric saws.

4. CONTROLBefore proceeding, check the correct O-Ring positioning, its integrity and cleanliness. Ensure also that there is no damage to the tube.

5. and 6. PIPE INSERTIONInsert the tube fully into the fitting, rotating slightly, and mark the tube. If a lubricant is required to assist with inserting the tube, ensure that it is suitable for use with the O-Ring and the application for the eventual fluid the system will transport.

7. and 8. TOOLS and PRESSINGPrior to pressing, prepare the tool by assembling all parts, jaws etc required for the press. Ensure that the specific instructions for the chosen tool are adhered to.Check battery has sufficient charge, that jaws are in good condition, clean and lubricated, and are the correct profile. (M profile).To perform perfect pressing, put the fitting inside the jaw and keep the tool positioned at right angle (90°) to the pipe. Ensure that the toroidal chamber of the fitting (which contains the O-Ring is properly positioned inside corresponding groove of the jaw. Then begin pressing the junction; the pliers will automatically perform the deformation until its completion.

Slings are used for pressing fittings in sizes from 42mm to 108mm.Slings are used in conjunction with adaptors and the specific procedure for the chosen tool should be followed. With the correct adaptor fitted to the press tool, engage the adaptor to the sling and press the trigger to start the pressing. Once complete the sling can be disconnected and removed from the fitting.

8.1 PROCEDURE FOR 108MM FITTINGS108mm fittings require two presses. The specific procedure for the chosen tool type should be followed and adhered to and whilst there are tools on the market that can make a 108mm joint with a single press, most tools require a double press process.

This is generally achieved using two different adaptors to ensure sufficient force is applied to complete the press. In these instances, the tool should be supplied with a 108mm Adaptor (1) and Adaptor (2).

Two presses are made using the same sling but in sequence with the two adaptors. It is good practice to rotate the sling to a different position on the fitting for the second press.

5.4 FITTING DEPTHS

The installation depths and the coupling tolerances are designed and implemented with the utmost attention to ensure the highest degree of safety of the junction.

7. THERMAL EXPANSIONS

For all the types of pipes constituting a distribution network the elongations or contractions due to thermal expansions as a result of the increase or decrease of temperature of the conveyed fluid must be evaluated.

To compensate for these effects, the necessary space for the expansions, the proper placement of fixed sliding support points, and the realization of any line compensators must be provided.

It is necessary to determine the extension of a given part of pipe [∆L] based on a certain thermal variation [∆T]. The equation used to calculate the extension is:

∆L = L • α • ∆T

With

∆L: global elongation [m] L: length of the piping [m] α: linear expansion coefficient (typical for every material see table below) [K-1]

Material α: linear expansion coefficient [K-1]

Copper 16,6 10-6

Carbon steel 12,0 10-6

Example:

in a straight copper tubing, which is 40 m long and installed at a room temperature of 5 °C and which can reach an operating temperature of 85 °C, the elongation is:

∆L = 40 • 0.0000166 • (85 - 5) = 0.0531 m

which corresponds to 53 mm If the conduit is found between two fixed pieces of equipment (e.g. a pump and a heat exchange group) and has a limited diameter (e.g. 18 x 1.0), only bending of the pipe would most likely be found as a result of expansion, with harmful consequences for any intermediate bodies (valves or others).

If the pipe has a larger diameter (e.g. 54 x 1.5) and therefore less elasticity, elevated axial effects could occur.

Small longitudinal changes in piping can be absorbed by the elasticity of the pipe itself while in large pipe networks Elongation compensators are required.

8. TESTING & COMMISSIONING

Testing & Commissioning of the installation should be carried out in conjunction with all local Legislation, Standards & Codes of practice.

Pressure testing during commissioning for carbon steel press fittings

Pressure testing can be performed using air (or inert gases like nitrogen) or water. A different or specific testing method might be required by commissioning schemes.

CARBON STEEL

Testing with water will most probably (even after emptying and drying) leave some water remains which may highly increase the risk of corrosion inside the piping. Therefore, in case the system has to be left empty (not in use) even for a short time, a pressure test with dry air or inert gas should be performed.

Leak test and Tightness test

Generally, Leak test (low pressure test to check for leaks) is to be performed with air or inert gas while Tightness test (higher pressure test to check for integrity and strength of the system) is to be performed with water.

Leak test shall be performed with dry air or a dry and clean nitrogen-rich air mixture. Test pressure shall be kept below 1 bar (0.5 bars is generally considered ok). Air shall be free from oil to avoid any contamination or damage to the EPDM O-Ring. Test times shall be 30 minutes minimum up to an hour. Leak test can be performed also by hydraulic pressure testing: in this case pressure shall be kept at 0.5 bar.

Tightness test shall be hydraulic and as generally required by EU standards and Regulations the water systems shall be capable of withstanding an internal pressure of 1,5 times the maximum operating pressure. Test time is 1 hour minimum.

If, after the tightness test, leaving the system full of water is not possible then the piping shall be fully drained and dried by purging with dry air/nitrogen.

CARBON STEEL

If leaving the system full of water is not possible then the tightness test should not be carried out until such time as it is possible to do so and leave the system full on completion of the test.

In case leaks or damaged fittings are found during the leak or tightness test, the fittings must be replaced and the tests performed once again.

9. WARRANTY

To preserve Warranty, the installation must be carried out in accordance with the Installation Manual and not subjected to any conditions prior to, during, or following installation which could attribute to material failure.
