ARPOL TRANS - Fitting instructionsAll ARPOL couplings are supplied with the following basic fitting instructions on the label:ƒƒƒƒARPOL reference which includes the tolerance. Should different O.D. be joined, pleasecheck admissible values.Working Pressure (bar)Test Pressure = 1,5 working pressureTorque value (N/m)In order to enable the ARPOL coupling to work correctly it is very important torespect the torque value.To fit the ARPOL trans couplings, we recommend following these steps:1 ƒ Clean pipe ends and eliminate any irregularity.2 ƒ Mark both pipe ends symmetrically at a distance from the edge equivalent to half ofthe coupling width.3 ƒ Confirm that the coupling orientation is the adequate: The thicker rubber end is place atthe smaller diameter.4 ƒ Slide the coupling over one pipe end without opening the coupling.5 ƒ Bring the other pipe end to a facing position. Make sure the pipes are aligned concentricallyand that both pipe ends are correctly supported.6 ƒ Place the coupling between the marks and confirm that the inner steel bridge is correctlyplaced under the lock.7 ƒ Tighten screws:When the coupling has more than one lock, it is important to confirm that all thelocks are equally open, even if the different bolts in each lock are not identicallytightened.7.1. Start the tightening of screws using a click wrench with a nozzle.· 2 screws lock: tighten both screws by alternative short movements until younearly reach the end, but do not exceed the torque value.· 3 screws lock: First tighten the central screw up to 10 mm.Then tighten exterior screws positioning them at the same level as the centralscrew. Keep tightening the three screws by alternative short movements until younearly reach the end, but do not exceed the torque value.7.2. Finish the tightening with a dynamometric wrench with sound signal.· Adjust the wrench to the torque value printed on the coupling label. Keeptightening screws alternatively with the dynamometric wrench until you can hearthe ‘click sound’ at the beginning of the tightening.8 ƒ If necessary, you may hydraulically test the coupling up to 1.5 the working pressure(see label).


ARPOL TRANS COUPLINGS:X ÷ 2X ÷ 2THE DIFFERENCE IN O.D. MUST BE EQUALLY DISTRIBUTEDThe locks absorb part of the difference between O.D.s (A). Furthermore,couplings are fitted with a special rubber gasket that balances the remainingdifference.AIt is important thatgaps betweenlocks must beuniform.ARPOL TRANS COUPLINGS ARE NOT DESIGNED TO SUPPORT THE PIPE ORTO PREVENT AXIAL MOVEMENTS. THEREFORE, THE PIPE MUST BEPROPERLY SUPPORTED AND ANCHORED.
