PVC pipes can be useful in tight places and around plumbing structures, however, it is not easy to do so. In this article, our plumbers in Singapore explain how to bend a PVC pipe.
Heating the PVC pipe in Singapore
PVC pipes are made through a procedure called extrusion. Chips or breads of solid PVC plastic are heated up to a melted state and pushed through a hole with the desired shape.
While the pipe is extruded, it is placed in a straight plane until it cools into the solid pipe state.
Also, our plumber in Singapore considers important to mention that PVC is a thermoplastic, meaning it becomes soft when heated.
The most appropriate instrument for heating a line in order to bend a PVC pipe is a heat gun. What is not advisable to use, however, is the propane torch because the heat is too focused, therefore charring the pipe is extremely likely.
A PVC pipe is heated is by using a constant movement. The pipe or the heat source has to be moved back and forth on a 12” area, while rotating the pipe all the time.
Three to four minutes later, the pipe piece will begin to sag. The pipe has to be moved and rotated by our plumbers in Singapore and then it will be bent, while still applying the heat.
Finishing the bend of the PVC pipe in Singapore
After the PVC pipe has become soft, it is placed down by our Singapore plumbing professionals on a straight surface and it is bent while rotating it.
The pipe is not bent quickly and the plumber has to keep on rotating it, otherwise, the pipe might kink. After the pipe has acquired the right angle, it is held while it cools.
What are PVC pipes used for?
PVC pipes are usually utilized as electrical conduits and for irrigation piping. This material is solid and strong, not being able to bend at all while in its normal state.
Instead of using elbows or couplings, our plumbers sometimes choose to bend a PVC pipe without breaking or kinking it.
