What’s the difference ? Furniture grade PVC is slightly different from standard plumbing PVC in several ways. Aesthetically, furniture grade PVC is shinier and is free from writing or bar codes. This gives a more polished look than standard PVC which often has markings or imperfections.
There are two common types of PVC pipe – schedule 40 PVC and schedule 80 PVC . Schedule 40 PVC is usually white in color and schedule 80 is usually a dark gray (they can also be found in other colors). Their most important difference , though, is in their design. Schedule 80 pipe is designed with a thicker wall.
Furniture – grade wood is considered the crème de la crème of the cabinet options. These planks have tighter and more appealing wood grains (or hardly any grain at all), they are more durable and cabinets built from furniture – grade wood lasts for generations.
Class number for PVC pipe denotes its pressure rating; examples are Class 315, Class 200 , Class 160, Class 125, etc. The industry standard is to have a built-in safety factor of 2:1 for pressure surges, so a Class 200 pipe could probably withstand 400 psi water hammer (shock) pressures.
The effects are color change, slight increase in tensile strength, slight increase in modulus of tensile elasticity, and a slight decrease in impact resistance. Furniture – grade PVC pipe and fittings are more impact-resistant and have no printing or stampings on the exposed exterior.
PVC contains harmful carcinogens, most notably VCM. Other chemicals such as dioxin and phthalates, both carcinogenic, may also be released into an indoor environment, endangering the people who work and live in buildings that use PVC . Phthalates are carcinogenic chemicals often used in plastics to make them flexible.
Chlorinated polyvinyl chloride ( CPVC ) For homes, it’s great for carrying drinking water and handling the hot water lines for which PVC is unsuited. CPVC is more flexible as well.

When you install a sprinkler system , you might use PVC or polyethylene piping to deliver water to the sprinkler heads. If you use PVC, the typical diameter of the pipes is between 1/2 inch and 2 inches. The right size pipe depends on the overall capacity of your system .
PVC Schedule 40
PVC Schedule (abbrev. SCH or Sch .) is the thickness of the PVC pipe wall. The most common Schedule is 40, but Schedule 80 PVC is also available. As the schedule gets larger the pipe wall gets thicker from the outside in, so the inside hole (bore) of the pipe gets smaller.
