CPVC sprinkler pipe inside a firestop mock-up. Chlorinated polyvinyl chloride (CPVC) is a thermoplastic produced by chlorination of polyvinyl chloride (PVC) resin. CPVC is significantly more flexible than PVC, and can also withstand higher temperatures. Uses include hot and cold water delivery pipes and industrial liquid handling.
They tend to use the CPVC for extra fire retardancy in occupancies that are below a certain height, depending on the local building code. Plastic pipe has a big lobby of course. I know one thing, that when you run a fire test with plastic pipe, it does not matter whether it's CPVC or PVC, it makes ONE HELL OF A MESS. I find the use of plastic ...
This is a list of cleaning products and agents. Cleaning agents are substances (usually liquids, powders, sprays, or granules) used to remove dirt, including dust, stains, bad smells, and clutter on surfaces. Purposes of cleaning agents include health, beauty, removing offensive odor, and avoiding the spread of dirt and contaminants to oneself ...
This increase in elemental chlorine content contributes to CPVC's increased expression of chlorine-based characteristics, such as chemical durability, resistance to acids, bases, and salts; susceptibility to ammonia-based compounds, aromatics, esters, ketones; [9] chemical stability; heat energy transfer resistance. CPVC is commonly used in ...

The number system, like Sch 40, 80, 160, were set long ago and seem a little odd. For example, Sch 20 pipe is even thinner than Sch 40, but same OD. And while these pipes are based on old steel pipe sizes, there is other pipe, like cpvc for heated water, that uses pipe sizes, inside and out, based on old copper pipe size standards instead of steel.
The main advantage is that it can easily be removed and re-used, it is easy to assemble, and the joints are still rotatable even after assembly. The pipe end should be square, so it sits against the stop in the fittings and does not create turbulence, and needs to be a clean cut to avoid damaging the O-ring during insertion. [29]
To start, a diluted cleaning solution (white vinegar, bleach and detergent) is sprayed onto all surfaces to be cleaned, Using the same machine, the area is then rinsed; this is typically followed by vacuum suctioning that removes the applied liquid along with the suspended solids and dissolved contaminants that have been removed from the surface.
