Types of Plastic Pipes
The plumbing industry primarily uses seven types of plastic pipes, each of which
has a different application and installation requirement.
ABS PIPES
www.psppipe.com
PVC - (Polyvinyl chloride) Pipes:
This is a rigid pipe with high impact strength manufactured from thermoplastic
materials. This material is long-lasting, and can also be used for DWV system for
bigger pipes and for cold water systems for the smaller pipes. This type of pipe is
resistant to chemical and are recommended for used to transport many chemicals
from one point to another.
Note: Solid core PVC pipes can be used in high pressure systems, but is not
advisable to carry high temperature water.
PVC PIPES

46. 43
CPVC Pipes:
CPVC means Chlorinated polyvinyl chloride made from an engineered vinyl
polymer. It is very much recommended for hot and cold water distribution systems
and is also acceptable for indoor use.
CPVC has the following features:
It is lightweight and easy to install.
It looks neat and clean being white in color.
It is durable for hot and cold water temperature.
Its molecular structure practically eliminates condensation in the summer and
heat loss in the winter.
CPVC PIPES

PE Pipes:
PE means Polyethylene and is a thermosetting plastic. It is commonly used by
plumbers for piping system because it is resistant to chemical and corrosion, it is
flexible and durable, and strength. Furthermore, Polyethylene does not deteriorate
when exposed to the rays of the sunlight.
PE PIPES

47. 44
PEX Pipes:
PEX stands for Cross-linked polyethylene tubing and was formed by
subjecting high density polyethylene to heat and high pressure. This type of pipe is
commonly used for manifold plumbing distribution systems because of its flexibility.
PEX PIPES

PB Pipes:
PB means Polyebutylene is a thermoplastic pipe that is very popular
extensively for water supply piping from the late-1970s to the mid-1990s. However, in
many cases, the PB piping has become weak and may faile without warning.

48. 45
PPR-"polypropylene random”
PPR - Presently PP-R pipes & fittings are most reliable in plumbing and water
supply plants, due to their chemical features and fusion welding, which ensures the
plumbing to have a perfect seal tight system. It can be used both as a cold water
pipe or a hot water pipe.
PPR is joined by a fusion machine that heated both the socket and the pipe
and when melted, both parts are joined together and becomes almost unbreakable.
As a technical expert in plumbing, I always recommend this type of pipe because it
has a strength five times far greater than the G.I. pipe and has a bursting capacity
of more than 300 psi.

A rigid pipe with high impact strength, PVC is manufactured from
thermoplastic materials.
Solid core PVC pipes can be used in high pressure systems, but only to
carry high temperature water.
CPVC pipes and fittings are made from an engineered vinyl polymer.
Plumbers use CPVC in hot and cold water distribution systems.
CPVC is not acceptable for indoor use.
CPVC is lightweight and not easy to install.

PE is a thermosetting plastic.
Plumbers commonly use PE for tubing because of its strength, flexibility,
and chemical resistant properties.
PE is also corrosion-resistant which makes it ideal for transporting
chemical compounds.
PE does not deteriorate when exposed to sunlight
Plumbers commonly use PEX for manifold plumbing distribution systems
because of its flexibility.
PBB is a thermoplastic pipe that plumbers used extensively for water
supply piping from the late-1970s to the mid-1990s.
It can be used both as a cold water pipe or a hot water pipe.
PPR is joined by heating both the socket and the pipe.
