The trick is to first anneal the copper pipe in the area of the bend,and re-anneal as soon as you feel the pipe starts to work harden. Adjust the pipe so that the random mark that was previously made lines up with the leading edge of the die.

Kinks in pipes of any kind reduce the diameter of a pipe and if the diameter is reduced, the flow is reduced and the whole system becomes less effective as well as being more prone to blockage and irregular pressures. To use a pipe bender, simply place the pipe in between the two levers, then pull the adjustable lever until the desired angle is achieved.Pipe benders come in a variety of sizes catering for copper pipes from 6mm to 38mm and are operated by hand.

The handles (2) are opened wide which allows the hook (1) and the stay (3) to be in a straight line.

Mini pipe bender - The exact opposite of the free standing pipe bender, mini pipe benders are designed to achieve portability over power. Many pipe benders or tube bender kits will be designed for a specific job or application, so choose wisely. This is one of the reasons plumbers prefer to use a copper pipe bender rather than simply cut the pipe and put a bend fitting like an elbow into the run to change direction.

Bespoke automakers often use them to bend exhaust pipes and other automotive accessories into shape. I seem to remember seeing a very nice pipe bending machine at one Donington exhibition-it may have been on the Derby Society stand,and I seem to think the design for this was published a while ago. Pipe springs can be used in pipes up to 22mm diameter but bending a 22mm pipe with a spring is a herculean task which none of us would attempt.

As you bend the pipe, engage the subsequent teeth of the drive rack and work your way down to the last notch. This makes them great for remote working, or for working near any pipes that don't have a power source nearby. Introductions are limited to motor finance, CarMoney Limited will pay us a fixed commission per paid out deal.

To try and achieve a reasonable and tidy appearance, I thought the use of a pipe bender would be better than bending by hand. LBSC' used to suggest molten lead in our small bore copper tubes, but it's difficult enough to pour molten lead into a half inch diameter tube, let alone an eighth of an inch or so! Degree - Most pipe benders bend to a 90 degree angle, however some bend to 180 degrees and beyond for specialist jobs.
