|Push fit jointing to copper pipe
Equator fittings can be easily jointed to copper pipe to BS2871 Part 1, table W and BS EN 1057-R250.
No special adaptors are required to make these joints.
No pipe support sleeves are needed for copper pipe.
It is also possible to join soft copper to Equator push-fit fittings, however, extra care is needed because it is susceptible to becoming misshaped or dented if misshandled on site.
When jointing copper pipe to Equator fittings, ensure that the copper pipe end is cut square and de-burred. Check to make sure the copper pipe is not dented.
Any flaws could damage the O-ring during insertion which could affect the joint seal.
When using Equator pipe or fittings next to soldered copper fittings, it is recommended to complete the soldering before any Equator pipe or fittings are installed.
Where this is not possible, the following recommendations should be followed:
Do not allow flux to run onto Equator pipe or fittings.
Keep Equator products away from any sources of naked flame, wrap a damp cloth around the copper pipe during soldering
Do not allow hot solder to come into contact with any Equator products
|Jointing to compression fittings
Equator pipe may be jointed to brass compression fittings complying with BS864: Part 2: Type A. The correct jointing procedure is as follows:
In general follow the procedure as detailed in the Making a push-fit joint described earlier.
1 Slide capnut and compression olive onto the pipe.
2 Push a pipe support sleeve into the pipe end.
3 Ensure that the olive will sit on the section of pipe lined by the support sleeve.
4 Apply several turns of PTFE sealing tape over the olive and assemble the joint.
5 After tightening the capnut by hand, further tighten to compress the olive firmly against the pipe.
6 To confirm that the joint is secure, hold the fitting and tug backward on the pipe.
Equator pipe should not rotate
in compression fitting after tightening
|Jointing to screwed ends
Equator pipe may be jointed to screwed pipe ends or threaded fittings by using the appropriate male or female adaptor from the Equator range. Before jointing to male components PTFE tape should be applied to the screwed threads.
For joining Equator pipe to taps having threaded male spigots, the appropriate straight or bent tap connector from the Equator range should be used.
A fibre washer (supplied) should be used on the swivel flange or alternatively PTFE tape may be applied.
DO NOT USE ANY SEALING COMPOUND.
The natural flexibility of the pipe should be used wherever possible to overcome obstacles and to form changes of direction.
Cold-formed bends can be made by hand and fixed in position by fixing clips. Do not bend the pipe excessively as it may kink.
Minimum bend radii should be observed to ensure pipe longevity, see table 8 below.
Pipes should be fixed using either the nail or screw clips. Nail clips are primarily designed for fixing to timber where pipe installation is not required.
If the installer intends to use screw clips other than Equator, these should be the clip-lock type, not the open saddle type.
Where piping is to be insulated, pipe clip spacers should be used with screw clips.
Where piping is to run adjacent to a suitable support member and does not require lagging the use of plastic cable ties is acceptable, providing they are suitable for the operating temperature of the system.
The recommended support distances, shown in Table 9, should be used when good pipe alignment is critical for proper system operation, ie. for a horizontal section of a vent pipe or when maximum neatness is required.
When 10mm or 15mm piping is run within a concealed void, it is usually acceptable to reduce the pipe fixing providing the risks listed under routing of pipework can be avoided, as detailed in the Equator Design and Installation Guide.
For visible surface fixed pipework a rigid pipe should be used, such as copper.
