Plastic Pipe Clips are used to bracket a pipe system generally to a flat surface or substrate, such as a ceiling or wall. The distance between each support point is often referred to as support centres. The distance between pipe clips depends on the size of pipe, type of pipe and the temperature of the fluid flowing through it.
Pipes will need to be placed at varying distances dependent on the material of the pipe, be it PVC-U, ABS or PP pipe. When it comes to plastics, PP is generally the lightest followed by ABS and then by PVC-U.
Plastic Pipes will ‘soften’ and become more ductile at higher temperatures. The spacing of pipe clips therefore relies heavily on varying factors, however the general rule is that the hotter the contents the more frequent support centres need to be placed to prevent pipe from sagging or ‘snaking’.
Sagging pipes can lead to a build-up of unwanted solids and result in pipe flow being hampered or blocked.
Pipe clips should allow unrestricted, lateral movement along a pipe’s axis. epco pipe clips are designed to meet these very requirements.
Black PP Industrial Pipe Clip
Made from PP (Polypropylene), theses injection moulded plastic pipe clips are available in various sizes from 16mm to 125mm. With an optional use along with industrial spacing blocks to increase the gap from the celling or wall to the pipe.
Green Rubber Pipe Clip
Rubber Lined Pipe Clips have a two-screw clamp, quick locking system, with removable spacer washers making the clamp suitable for either sliding or anchoring with a noise insulating and smooth lining to allow expansion and contraction of the pipe.
Quick Clamp Pipe Clip
Quick Clamp Pipe Clips are used to bracket a pipe system to surfaces such as a ceiling or wall. The clip is designed from one part and fixes quickly and easily by use of a built-in clamp.

The details shown are for horizontal pipes made of PVC. For vertical pipes, support centres may be increased by 50%.
While each pipe clip is suited to varied requirements, careful consideration is required when installing pipes. There are two support types being free and fixed, both require varying placement.
A free support allows the pipe to move without restraint along its axis while still being supported, this is an important consideration when designing pipework installation and expansion rates, alternatively, a swinging type of support can be used. Both support types will require some sort of pipe covering to prevent rubbing and or scuffing.
A fixed support rigidly connects the pipeline to a structure totally restricting movement in at least two planes of direction. Such a support can be used to absorb any pipe movement.
One must always pay careful attention to the layout of pipe and the placement of pipe supports. Even if a pipe system is non-pressurized, the effects of expansion and contraction must be considered. Ensure that a pipe system does not significantly bend at its rigid connections, which will include fittings such as bends, elbows or tees.
For a solvent-cement jointed pipe system any expansion coupling must be securely clamped with a fixed support. Other plastic pipe clamps should allow for movement due to expansion and contraction. Rubber-ring jointed pipe should have fixed supports behind each pipe socket.
epco has always endorsed the use of our Pipe Clip range along with our pressure pipe systems as we are guaranteed by manufacturers that the plastics, metals and or rubber liners used are 100% safe. We will not guarantee our pressure system when used along with cheaper pipe clips sourced from other locations.
