CPVC tubing comes in nominal sizes ranging from 1/2 to 6 in. CPVC tubing is SDR11, SDR 13.5 & SDR 17 (1/2 to 6 in.) with standard hydrostatic pressure ratings of 400 psi at 73ºF (2,750 kPa at 23ºC) and 100 psi at 180ºF (690 kPa at 82ºC). Consult the speciﬁc CPVC pipe manufacturer’s literature and listings for appropriate pressure ratings. CPVC tubing and pipe are sold in straight lengths. Deﬁnition: is PVC (polyvinyl chloride) that has been chlorinated via a free radical chlorination reaction. CPVC is produced by adding chlorine to PVC in a water slurry or ﬂuidized bed chlorination process. The chlorination reaction is initiated by ultraviolet light. The chlorinated PVC is compounded with ingredients necessary for the desired properties for further processing. The chlorine added to PVC gives CPVC higher temperature performance and improved ﬁre and corrosion resistance.

TECHNICAL SPECIFICATIONS

Overview: CPVC is a high-temperature plastic pressure piping system introduced for potable plumbing in 1959. It has also been used extensively in ﬁre sprinkler systems since 1985. This material is also used for many industrial and process piping applications. CPVC pipe is available in nominal sizes from 1/2″ to 24″ and is approved in all model plumbing and mechanical codes across the United States and Canada. In addition, CPVC pipe and ﬁttings from select manufacturers are listed for light hazard ﬁre sprinkler systems, as deﬁned in NFPA 13, 13R and 13D standards.

Fire protection: One- and Two-Family Dwellings and Manufactured Homes (NFPA 13D), Low-Rise. Residential Occupancies (NFPA 13R) and Light Hazard Occupancies (NFPA 13)
Reclaimed water piping (purple pipe)
Chilled water piping
Hydronic piping and distribution (radiators, fan coils, etc.)
Suitable for many industrial and process piping applications

CPVC Plumbing system is designed for Hot & Cold water which is suitable for all plumbing and potable water application. It has a proven hot & cold water performance from 0° C to 93°C. Its corrosion resistance property makes it usable in all weather & ensures constant ﬂow over lifetime. This system is used in industrial, residential, commercial & public complexes.

NOTE

The above pipes are recommended for water temperatures ranging from +10C to +900C.
The recommended Maximum safe working stress for these pipes is Mpa at 270C
Occasional rise in temperatures as in summer seasons with concurrent corresponding reduction in temperatures during nights has no deleterious effect on the life/working pressure of the pipes Considering the total life of pipes.

CPVC PIPING SYSTEM

	DO’S	DON’TS
	CUTTING It is imperative to mark the pipe from all sides so that pipe is cut with the help of a Hand Saw. It should be a right angle cut from all the sides, The cut piece should not be with burr on edges	CUTTING Do not cut slant/ unevenly.
	CHAMFERING After cutting the pipe needs to be chamfered from the outer sides. It is advisable to provide approximately 2mm wide, slight chamfer on spigot end of the pipe into the socket of the ﬁtting.	CHAMFERING Do not proceed with installation of pipe without chamfering.
	DEBURRING AND RIDEGE REMOVAL Remove all the burrs and ridges accumulated on the inner as well as the outer edges of the pipe with the help of a deburring knife, ﬁle or abrasive paper	DEBURRING AND RIDEGE REMOVAL Do not proceed with installation of pipe without deburring.
	DRYFIT TEST Before applying solvent cement, insert the pipe end into the socket of the next pipe end into the socket of the next pipe or ﬁtting to check that interference occurs at about 1/3 to 2/3 of the socket depth.	DRYFIT TEST Do not apply solvent cement without dryﬁt test.
	CLEANING Thoroughly clean the pipe with dry cloth where the solvent cement is going to be applied to avoid dust, dirt, oil, moisture and other foreign material during the installation process	CLEANING Do not joint the pipes without cleaning the pipe ends.
	APPLICATION OF SOLVENT CEMENT Mark the pipe length to be inserted for jointing. Apply a liberal coat of solvent cement with the help of the brush on the marked surface	APPLICATION OF SOLVENT CEMENT Do not apply excess solvent cement on the pipe and do not use solvent cement by hand.
	JOINTING Push the pipe inside the ﬁtting/ pipe so that it goes inside equally from all the sides. Wipe off excess solvent cement that comes out of the edges. Hold the joint for one to two minutes so that the jointing is perfect. FOR THREADED JOINTS • Clean the Male & Female threads. • Apply Teﬂon tape in the direction of thread tightening Hand tighten the threads ﬁrmly • Tighten the joint more by using pipe wrench • Do not over tighten. Userubber packing to avoid scratches on pipe	JOINTING Do not use a hammer or half push the pipes. FOR THREADED JOINTS Don’t over tighten with pipe wrench.
