Plastics Technical Manual
• WhileABS,PVCandCPVCareverydifferentmaterials,
they share numerous advantages common to plastic piping
systems. Advantages include ease of installation, corrosion
resistance, low friction loss, initial cost, and longevity.
Easy Installation
• ABS, PVC and CPVC systems are light in weight
(approximately one-half the weight of aluminum and
one-sixth the weight of steel) reducing transportation,
handling, and installation cost. They have smooth,
seamlessinteriorwalls.Nospecialtoolsarerequiredfor
cutting. These materials can be installed using the solvent
cement joining technique.
Strength
• ABS,PVCandCPVCproductsarehighlyresilient,tough
and durable with high tensile and high impact strength.
Freedom from Toxicity, Odors, Tastes
• PVC and CPVC pipingsystems designed for domestic
water applications are listed to conform to NSF
InternationalStandard61.ThisHealthEffectsstandard
ensures the safety of products coming into contact with
drinking water.
Corrosion Free External and Internal
• With many other pipe materials,slight corrosion may
occur. The corroded particles can contaminate the
piped fluid, complicating further processing, or causing
bad taste, odors, or discoloration. This is particularly
undesirable when the piped fluid is for domestic
consumption.WithPVCandCPVC,therearenocorrosive
by-products, therefore, no contamination of the piped
fluid.
Immunity to Galvanic or Electrolytic Attack
• ABS,PVCandCPVCareinherentlyimmunetogalvanic
or electrolytic action. They can be used underground,
underwater, in the presence of metals, and can be
connected to metals.
Fire Resistance
• PVC and CPVC piping systems are self extinguishing
andwillnotsupportcombustion.TheASTME84test
protocol is used to determine the flame and smoke rating
for various materials.
• PVCwillnotpasstheASTME-8425/50amespread
/smokedevelopedtestandisnotacceptableforusein
plenum areas.
• Consult Charlotte Pipe for additional information on
CPVC in plenum applications.
• For plenum applications, follow prevailing code
requirements.
Low Friction Loss
• The smooth interior surfaces of ABS, ABS Plus, PVC
and CPVC assure low friction loss and high flow rate.
Additionally, since ABS, PVC and CPVC pipe resist
rusting, pitting, scaling and corrosion, the high flow rate
can be maintained for the life of the piping system.
Low Thermal Conductivity
• PVC and CPVC pipe have a much lower thermal
conductivity factor than metal pipe. Therefore, fluids
being piped maintain a more constant temperature. In
many cases, pipe insulation is not required.

To reduce the risk of death or serious injury from an explo-
sion, collapse or projectile hazard and to reduce the risk of
property damage from a system failure:
• Always follow the warnings and procedures provided in
this manual.
• Only use PVC/ABS/CPVC pipe and fitting for the
conveyance of fluids as defined within the applicable
ASTM standards.
• Never use PVC/ABS/CPVC pipe and fittings for the
conveyance of gasses.
• Never use PVC/ABS/CPVC pipe or fittings in structural
application or in any load-bearing applications.
• Never strike the pipe or fittings or drive them into the
ground or into any other hard substance.
