Similarly, external springs support the pipe on the outside. It supports the pipe as it’s bent to ensure that it doesn’t collapse. An internal spring is inserted into a pipe immediately after it has been heated. There are two types of springs available: internal and external.

Related: How to Bend Pipe with a Pipe Bender Bending Springsīending springs are simple tools which prevent pipes from developing a kink when bent. Sometimes it makes things easier if one person heats the pipe while the other bends. If you’re still having difficulty bending the pipe, rope in someone else to help. If you have difficulty getting leverage, try using a wrench. You can do this with your hands, but wear thick gloves as the pipe will be extremely hot. When the pipe is red hot, gently start to bend it. Remember to heat the whole area and not just one side of the pipe as this will help it bend evenly. With your blow torch, apply constant heat to the area you want to bend. Make sure there is a decent amount of space either side of the area you want to bend so that you can get a good grip when bending. Secure your pipe in a vice so it can’t move. Most people use cheap wooden material, such as MDF, to create large-scale templates. It’s also a good idea to create a template of the bend and measure your pipe against it as you go. Before embarking on any technique, make sure you mark out where you want to bend. There are a number of ways to use heat to bend pipes, which we outline below. Extreme heat is concentrated on the area you want to bend, making it malleable. One of the most common ways to bend pipes without a machine is by using a blow torch. Then, firmly grip the ends and choose the most comfortable position to bend, for example an overhand grip with the bar straight out in front of you. Simply cut some into strips and wrap them around the ends of the bar-you can choose other materials, such as thick cloth, but they won’t provide the same amount of leverage. Leather is one of the best materials for this type of work. Before bending the pipe, it’s a good idea to wrap the ends in something to give you extra grip and protect your hands.
Most people can bend pipes up to an inch thick, but any more than that and you might need some tools or extra help. If you need a rough bend in your pipe and have limited resources you can simply use your bare hands. Softer metals will produce a ‘U’ shaped bend, while harder metals will look more like a ‘V’. Another thing to keep in mind is the type of bend you’ll achieve. Aluminium and copper are both soft enough to bend without much effort, but things will get considerably harder with alloys such as stainless steel. Naturally, humans have their limits and you’ll likely only be able to bend softer metals. There are some restrictions to bending metals without a machine. So next time you need to bend some piping for a project, you could rush to the hardware shop to grab a pipe bender, or you could simply give your muscles a workout. Most people can actually bend soft metals, such as copper and aluminium, with their bare hands. Circus strongmen in the 19th century bent steel with their bare hands to show off their amazing strength-but you don’t need to be dressed in a leopard-print leotard to carry out simple DIY tasks around the house.
