PPI's Building & Construction Division (BCD) is focused on plastic pressure pipe and tubing systems used within buildings
and on building premises for a wide variety of applications:
In some cases, multiple BCD materials listed on the Home page
may be suitable for use in the same
application, but this is not always the case.
Users should check with piping system manufacturers to be sure that their products are recommended for each
specific application and can be supported with design and installation advice. Selected products must also be
in compliance with relevant standards and local regulations, such as plumbing and mechanical codes.
Many pipe and tubing system manufacturers produce specific types of pipes for specific applications. For example:
- CPVC tubing (copper tubing size) is used in residential plumbing applications, while CPVC pipe (iron pipe size) is used in commercial plumbing, hydronics, fire protection and industrial piping systems.
- PEX or PE-RT tubing is available with an integrated oxygen diffusion barrier for closed-loop hydronic systems that need this type of protection against oxygen permeation. Open systems, such as hot- and cold-water plumbing, do not require such barriers.
- PP piping systems are available with a mid-wall layer that greatly reduces longitudinal thermal expansion and contraction. This is an important feature for those hydronic heating systems which can experience wide swings in fluid temperature.
Not all types of BCD products are approved for all applications.
