Explanation:
Elbow on 90°: To create a 90° elbow bend, the pipe is heated until it is malleable and then bent into a quarter circle shape using a bending machine or a press.
B. Offset Bend: To create an offset bend, the pipe is heated and bent in such a way that it creates an offset, or a "kink," in the pipe. This can be done using a bending machine or a press.
C. Three Point Saddle: To create a three point saddle bend, the pipe is heated and then bent over a saddle-shaped form using a bending machine or a press. This creates a bend with a "saddle" shape that allows the pipe to be mounted on a flat surface.
D. U-bend: To create a U-bend, the pipe is heated and then bent into a U shape using a bending machine or a press.
E. 45° Bend: To create a 45° bend, the pipe is heated and then bent at a 45° angle using a bending machine or a press.
F. Z-bend: To create a Z-bend, the pipe is heated and then bent into a Z shape using a bending machine or a press.
G. End Coupling: An end coupling is created by connecting two pipes together using a coupling, which is a short piece of pipe with threads on both ends. The pipes are first cleaned and then the coupling is attached to the ends of the pipes using a pipe wrench or other appropriate tool.
2. Some advantages of using PVC conduit for electrical wiring include that it is durable, easy to install, resistant to corrosion, and relatively low cost.
