In many applications, PVC is used because of its characteristics; low price, resistance to moisten and electricity, and strength. Plumbing, inner cable wiring and yard work are examples of home applications. It’s also ideal for do-it-yourself projects like constructing a specially made storage container or lawn furniture, or constructing a makeshift gazebo tent.
PVC is hard and rigid and used to perform various jobs. Different attachments and adapters are available to join pieces of pipe to achieve desirable shape for fluid movement. But sometimes it leads to leakage or you can’t achieve desirable shape with adapters and attachments.
In this case, you need to know can you bend a PVC pipe with a heat gun.
Here bending a PVC pipe is useful. You can save time, distress, and cash by shaping the piping to the superb curve for the job.
How to Bend PVC Pipe?
This process is very simple, you need to heat the pipe, bend it and let it cool to achieve desirable shape.
For this use a heat gun to bend the PVC pipe. Heat gun softens the material enough to mould it. Because of its high flow of air and powerful heat, Heat Gun performs admirably.
Connect the heat gun in a well-ventilated zone, arrange your PVC, and wear a pair of hard, heat-resistant gloves.
Step#1: Heating a PVC Pipe
Take a PVC pipe and heat it with a heat gun almost 3 to 4 inches above and move the heat gun back and forth (varying according to the size of the bend you want to attain). After few moves, rotate the pipe to heat up the opposite side of same area.
Repeat until the specimen has loosened to an appropriate standard. Under the heat, the pipe will start to droop visibly. When you notice this happening along a large portion of the layer meant to be bent, you can end.
Step#2: Bending PVC Pipe
Hold the pipe near the softened portion and bend it to achieve particular shape( never forget to wear gloves). Keep the pipe in your hand for few minutes so that it can not bend out from shape.
Once you moulded it in desirable shape, let it cool. Hose the pipe down with iced water, insert wet cloths over the heated curve, or simply leave it to cool by itself in a well-ventilated zone.
Frequently Asked Questions
At What Temperature Does PVC Pipe Become Bendable?
The average temperature for flexing PVC is 170 to 220 °, with 170 being ideal for long, sweeping curves and 220 required for strict bends.
Does Heating PVC Weaken It?
Heating PVC pipe can lead to instability on a practical level. PVC pipes, which have a melting temperature of about 176 ℉, may bend as the specimen reaches this temperature. Active PVC pipes must never be heated above 158 ℉.
Bending a PVC pipe using a heat gun is easy. However, some points should be considered in mind. Even with careful and thoughtful motions, it is probable to kink the PVC during this stage of the process. If this happens, sand could be used as a remedy.
Fill up the length of the pipe with sand and a lid on both ends at the start of the process. Continue with the next steps after heating the pipe as usual. The sand forms a tight heating element, preventing the PVC from twisting during the bend.
