The purpose of pipework insulation material is to reduce heat loss or gain in piping systems, thereby improving energy efficiency. It helps maintain the desired temperature of the fluids within the pipes, preventing condensation and protecting against corrosion. Additionally, insulation can enhance safety by reducing the risk of burns from hot surfaces and minimizing noise from fluid flow. Overall, it contributes to the longevity and performance of piping systems.
You didn;t say what you wanted the PVC pipe for. That is a material that is used for many project, plumbing, sprinklers to name a few. It is fairly eary to work with.
Plastic can be a lot of things, some will work well as insulation, some won't.
Asbestos when added to materials may provide strength, heat insulation, or fire resistance, among other properties.For example:Asbestos added to plaster makes the finished product more resistant to breaking when flexed (stronger).Asbestos adhering to structural steel insulates it from heat, thus letting it survive longer in a fire so that people escape the building and firefighters can work without the building collapsing on them.Asbestos incorporated into textiles makes them less likely to burn, and was used in theatre curtains and woven wiring insulation for that purpose.
An inside pipe wrench also called a pipe extractor. It drives into the broken off pipe and is then turned with a crescent wrench.Normally a extractor or inside pipe wrench does not work removing a pipe . What works best is the use of a hack saw blade and a chisel to cave in the threads after the threads are cut.. BECAREFUL not to cut into the fitting threads
Linemen work on live wires by using proper insulation gear, and by making sure that there is never any path for current to flow in case the insulation does fail. In some cases, the lineman can be raised to the potential of the line, but you still need the insulation, and you still need the technique of ensuring that no circuit can be accidentally created.

The best material for work gloves handling burning metal are typically made from leather and Kevlar with an insulation filling to prevent heat transfer through conduction. Insulation material and insulation grams will largely determine the duration of time a glove will resist heat.
pipe insulation have very low value of thermal conductivity. this is because of the air pockets or pores present in insulation or bad heat conducting elements such as glass...Most decent pipe insulation works by wrapping the pipe inside a mass of tiny air bubbles. ---------------------------------------------------------------------- Air is the insulation in almost all the available insulation's. It is important that the bubbles are very tiny as bubbles over 16mm will start a convection current that will transfer the heat across the cell. The problem with insulation is, it only slows the transfer of heat. Given time all the heat in a pipe will transfer through the insulation and the pipe will freeze. It is important that all exposed pipes and any pipes that are below freezing for some time are fitted with electrical ribbon heating to maintain their temperature above freezing.
*The best material to use would be foam insulation. It is cheap and they come is lengths that can be easily cut to fit and slide on. If the pipe is extremely hot, like a steam pipe, than it would melt the foam. You should use fiberglass insulation for this. It's a little more expensive but necessary. If there is an emergency or you want to get cheap than anything will work really. I've seen people use news paper or old clothes to keep their pipes from freezing. But that was only temporary because it will eventually get wet and rot. *When I say "best" I am considering the insulation qualities vs. the price. Fiberglass insulation is actually the best but it is more expensive. FYI: Insulation should not be crushed and don't leave big spaces between pieces. Good luck!
The R value measures how well insulation materials resist heat flow. A higher R value indicates better insulation effectiveness, as it means the material can better prevent heat from escaping or entering a building.

Telephone lines are made of iron or steel. Between the iron or steel core and the pipe is an insulating material. All Telephone lines are made and work this way.
To effectively remove a PVC pipe from a fitting, you can use a heat gun to soften the PVC material and then twist and pull the pipe out of the fitting. Alternatively, you can use a PVC pipe cutter to cut the pipe close to the fitting and then remove the remaining piece with pliers or a wrench. Be sure to wear protective gear and work carefully to avoid damaging the fitting or the pipe.
To wrap ductwork, start by cleaning the surface to ensure proper adhesion and insulation performance. Measure and cut insulation material, such as fiberglass or foam, to fit around the duct. Secure the insulation with duct tape or foil tape, ensuring there are no gaps or exposed areas. Finally, ensure that the insulation is snug but not overly tight, allowing for some expansion and contraction of the ductwork.
An example of a material that keeps heat from being lost is thermal insulation, such as fiberglass or foam. These materials work by trapping air pockets to reduce heat transfer through conduction, convection, and radiation. By slowing down the movement of heat, thermal insulation helps to maintain a comfortable temperature in buildings.

Alternatively, you can use a PVC pipe cutter to cut the pipe close to the fitting and then remove the remaining piece. Be sure to wear protective gear and work in a well-ventilated area when working with PVC and heat tools.
A megohmmeter, also known as a megger, works by applying a high voltage to the insulation of a material and measuring the resistance to the flow of current. By measuring the resistance, the megohmmeter can determine the condition of the insulation and whether any deterioration or defects are present. This helps in identifying potential faults or weaknesses in the insulation before they cause electrical issues.
