Chlorinated Poly Vinyl Chloride (CPVC) is a thermoplastic pipe and fitting material made with CPVC compounds meeting the requirements of ASTM Class 23447 as defined in ASTM Specification D1784. CPVC applications are for potable water distribution, corrosive fluid handling in industry, and fire suppression systems.
CPVC piping systems are:
Environmentally friendly
Provide long service life
Easy to install and handle
Corrosion resistant
Cost effective
CPVC piping which is suitable for hot and cold water distribution has a 400 psi pressure rating at room temperature, and a 100 psi pressure rating at 180°F.
CPVC materials are resistant to many everyday household chemicals.
A fitting is a detachable piece of pipe that connects two pipes or tubing. Fittings apply to mechanical and plumbing operations.
Different types of CPVC fittings have unique applications and uses. When shopping for a fitting, keep in mind that each fitting has a various amount of iteration and applications.
Below are some of the common types of CPVC fittings available.
CPVC tees fittings come with three ends; one at a perpendicular angle and two in a straight line. With a tee, you can either split a line into two with a 90-degree connection or connect two lines. They are in a standard design, implying that all outlets and inlets are of the same diameter.
Crosses are just like tees but are used to make a connection. With crosses, however, it’s a four slip connection. The pipes meet at a 90-degree angle forming a cross or plus shape. This means one input and three outputs or the reverse is also viable. Crosses are often used to divide fluid flow in four directions.
Elbow fittings commonly feature either a 45-or 90-degree bend. They are used to divert the direction of a pipe system. Side elbows however come with not two ends but three and are perfectly used as corners in a project. The market offers both elbows with slip pocket ends and threaded versions.
CPVC Coupling connects one pipe to another or a pipe to a fitting. Some coupling gives you an option of connecting a small pipe to a large pipe and the other way around. Couplings are either have slip or female thread ends.
Unions are similar to couplings but are designed in a way that they can be removed easily as opposed to coupling that is somehow permanent. Unions have a ring in the center that acts as a separator hence allowing for easy deconstruction and maintenance.
Caps’ primary function is to stop the flow. Their positioning is therefore at the end of the pipeline. Caps are designed with either a socket or female thread end, this means they go around or outside the pipe.
Plugs do function just like caps, but they stop the flow in a fitting as opposed to caps that stop the flow in a pipe. Plugs for this reason have a spigot or male threaded-end for they go inside a fitting.
Adapters act as reducing couplings. They are applicable a change to the end type of a pipe is needed so that they can connect to fittings and pipes of different sizes. The bushing on the other hand focuses on connecting pipes of varied diameters by reducing the fitting. Take note that bushing cannot reduce a pipe. Bushings are unique in the sense that they are typically threaded.
They are a disc-like fitting that presses two surfaces together hence creating a tight seal. This type of fitting is used to attach accessories to a pipe. They are commonly applied at the base of a toilet. CPVC flanges mostly use bolts to connect the two surfaces and are available with either slip or thread ends.
They are used to connect two female ends. The nipple comes with two male-threaded ends.
These are widely used plastic shut off valves. The valve contains a rotary ball with a bore at the center. By rotating the ball a quarter-turn, the bore can be aligned inline or perpendicular to the piping to open or block the medias flow.
