Sometimes pipework in your system needs to be bent in order to fit certain uses. A straightforward way to make bends in copper tubing is to use a specialist tool, called a pipe bender. These bending tools are made for different sizes of pipework:Small – 8/10 and 12mm pipes.Large ? 15 and 22mm pipes.There are pipes that are larger and would be very difficult to bend using a regular bending tool, so there would be a requirement to either, buy or hire a bigger powered bending tool, or dont bother and for copper pipework larger than 22mm diameter use fittings. Eltham Plumbers use pipe-bending tools.Bending Microbore: Smaller bending tools can be used to make bends in the very small microbore copper tubing. Microbore: This tubing is supplied in roles and is easy to hand bend. It is a pipe, normally 8-10mm in diameter and is used regularly in central heating systems having the main advantage of very low heat loss. It is also really flexible to run. But with this type of tube, to achieve a sharper, cleaner bend it is best to use a bending tool. An Eltham Plumber is experienced in pie bending techniques.To Bend:A). Open up the bender fully so its arms are 180 to each other. Place the copper tube between the arms and make sure it goes under the retaining arm and into the correct channel size. Bend the top parallel with the pipe in the grooves that are now enclosed. B). Pull the top arm down to begin the bend. Pull the arms together in one continuous movement until the correct angle is achieved. Open up the arms to release the bent tube and now remove from the tool.Note: A bender for copper pipe i.e. 15-22mm is available.
