Masts need to be RIGID.
Typically, EMT (Electrical Metallic Tubing) or RMC (Rigid Metal Conduit) is used for mast electrical service installations. These conduits provide protection for the electrical wiring from damage and are suitable for outdoor applications. The choice between EMT and RMC depends on factors such as the environment, code requirements, and specific installation needs.
A 770 Greenlee hydraulic pipe bender bend is used for rigid steel conduit from 2" to 4".
IT IS THE MOST USED ON UNDERGROUNG PIPE WORK
A mast type service entrance is a vertical structure that supports overhead electrical service wires leading into a building. It typically consists of a metal mast or pole mounted on the exterior of the building, which provides a secure and organized way to bring electrical power from the utility supply into the electrical system of the building. This type of service entrance is commonly used in residential and commercial applications where overhead power lines are present.
Mostly used for plumbing inside a house. -Personally, I prefer PEX, easier to install and lasts longer.
It's not used for making PVC resin, but it is used in processing it - they use it as a lubricant when making rigid PVC articles like pipe.
NO!! Black iron pipe has a special coating to resist the highly corrosive effect of natural gas. Galvenized pipe CANNOT be used for gas service.
A pipe,an fire extinguisher,rubber hose
A tool commonly used for threading rigid conduit is a pipe threading machine or a manual pipe threader. These tools create screw threads on the ends of the conduit, allowing for secure connections with fittings. For smaller jobs, a handheld die and handle can also be used to manually thread the conduit. Proper threading ensures a tight fit and helps maintain the integrity of electrical installations.
Heavier Angle iron is often used as a structural element in building and bridges, while lighter angle iron is used for a variety of supports such as an adjustable bed frame. Pound for pound angle is more rigid than standard pipe.
One way is to use an electricians snake, can be bought at home depot I think they run about $20, It's a long flat steel wire on a reel that you can feed through the mast . then hook your wire on it and pull it through. I had once used 10 foot 1/2" PVC pipes glued together and slid inside the mast with all wires protected inside the pipe. I assume you are talking about an aluminum mast? If it's wood you may be out of luck. hope this helps
Flex pipe should not have been used in your pool construction underground. It may be against code in most cities. The use of rigid shcedule 40 or sch 80 PVC is standard.
