Industrial CPVC pipe is manufactured by extrusion in sizes from ¼" to 12"
diameter to Sch 40, Sch 80, and SDR (Standard Dimension Ratio) dimensions.
CPVC pipe for plumbing systems is manufactured by extrusion in sizes ¼"
through 2" copper tube size (CTS) dimensions. The CTS plumbing
products are
made to copper tube outside diameter dimensions, in accordance with ASTM
D-2846 specifications, and have an SDR 11 wall thickness. The pressure
ratings of the CTS SDR 11 systems are 400 psi (pounds per square inch) at 73
F and 100 psi at 180 F. CPVC plumbing pipe is sold
in both straight lengths
and (in small diameters) coils.
USES/APPLICATIONS
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.
Since CPVC materials do not support combustion, they cannot burn
without an external fuel source. This property makes CPVC pipe an attractive
alternative to steel and copper pipe for fire sprinkler applications. CPVC
fire sprinkler piping systems are approved for light hazard applications and
for use in single and multifamily dwellings. Installation shall be in
accordance with the NFPA Section 13, 13D, and 13R.
CODE STATUS
CPVC piping for potable hot and cold water distribution systems is
recognized in all model plumbing codes.
Also, CPVC plumbing pipe is safe for installation in return air plenums;
however, the installation must be approved by the local jurisdiction. Even
though CPVC is considered a combustible material it will not burn without a
significant external flame source. Once the flame source is removed CPVC
will not sustain combustion. Testing indicates that water filled CPVC in
diameters 3" or less will pass the 25/50 flame smoke developed requirements
for non-metallic material in return air plenums.
CPVC fire sprinkler pipe tested and listed in accordance with UL 1887, "Fire
Test of Plastic Sprinkler Pipe for Flame and Smoke Characteristics," meets
the requirements of NFPA 90A for installation in return air plenums.
AVAILABILITY
CPVC pipe and fittings are produced by many manufacturers, and are available
in Schedule 40 and Schedule 80 dimensions, as well as CPVC tubing which is
suitable for potable hot and cold water distribution. The tubing is based on
copper tube sizes (OD) and IPS pipe (OD), with SDR 11 wall thicknesses.
MARKING
CPVC pipe
must be labeled at not more than 1.5 meters (5 feet) intervals as follows:
1.
The manufacturer's name or trademark
2.
The standard to which it conforms
3.
Pipe size
4.
Resin type or cell class according to ASTM D-1784, e.g. CPVC 23447
5.
Pressure rating
6.
SDR number or Schedule number
7.
If the pipe is for potable water, a laboratory seal or mark attesting to
suitability for potable water
DO'S & DONTS FOR INSTALLING
DO's FOR ALL
CONSTRUCTION
-
Read
the manufacturer's installation instructions.
-
Make
sure all thread sealants, gasket lubricants, and fire stop materials are
compatible with CPVC.
-
Keep
pipe and fittings in original packaging until needed.
-
Use
tools specifically designed for use with plastic pipe and fittings.
-
Cut the
pipe ends square.
-
Deburr
and bevel the pipe ends with a chamfering tool.
-
Use the
proper solvent cement and follow application instructions.
-
Rotate
the pipe at least ¼ turn when bottoming the pipe into the fitting
socket.
-
Avoid
puddling of cement in fittings and pipe.
-
Follow
the cement manufacturer's recommended cure times prior to pressure
testing.
-
Allow
CPVC tube slight movement to permit thermal expansion.
-
Use
plastic pipe straps that fully encircle the tube.
-
Drill
holes ¼" larger than the outside diameter of the tube, when penetrating
wood studs.
-
Use
protective pipe isolators when penetrating steel studs.
-
Use
metallic clevis or tear drop hangers when suspending tube from
all-thread rod.
DO's FOR UNDERSLAB CONSTRUCTION
-
Use
compatible sleeving material and tape.
-
Securely tape the top of the sleeve to the pipe.
-
Extend
pipe sleeve 12" above and below the slab.
-
Backfill and cover underground piping prior to spraying termiticide in
preparation for concrete pour.
DON'T DO's
FOR ALL CONSTRUCTION
-
Do not
use petroleum or solvent based sealants, lubricants, or fire stop
materials.
-
Do not
use edible oils, such as Crisco, for a lubricant.
-
Do not
use solvent cement that has exceeded its shelf life or has become
discolored or jelled.
-
Do not
pressure test until the recommended joint cure times are met.
-
Do not
thread, groove, or drill CPVC pipe.
-
Do not
overtighten or lock down the system.
-
Do not
install in cold weather without allowing for thermal expansion.
-
Do not
use tube straps which tend to restrict expansion/contraction.
-
Do not
use wood or plastic wedges that strain the tube as it passes through
wood studs.
-
Do not
use pipe isolators as tube passes through wood studs
-
Do not
bend CPVC tube around DWV stacks causing the two materials to bind
against each other.
-
Do not
terminate a run of tube against an immovable object (e.g., a floor
joist).
DON'T DO's
FOR UNDERSLAB CONSTRUCTION
-
Do not
allow heavy concentrations of termiticides to come into direct and
sustained contact with CPVC pipe.
-
Do not
inject termiticides into the annular space between the pipe wall and
sleeving material.
-
Do not
spray termiticide, when preparing a slab, without first backfilling over
underground piping.
-
Do not
cut sleeving too short. Sleeving material should extend 12" above and
below the slab.
