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.
Because Furniture Grade PVC pipe and fittings are designed for structural use, they are not National Sanitation Foundation (NSF) rated, and therefore should not be used for plumbing or pressurized systems, as these require NSF certification.
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.
PVC Class D Imperial Pipe is lightweight, durable and is rated for 12 bar pressure at +20°C. Pipe is supplied plain ended with a standard length being 6 metres, price on application for other end configurations i.e spigot and socket/rubber ring, with these being subject to minimum order quantities and lead times.
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.
This pipe is best suited for drainage, irrigation, and other cold water systems. Schedule 40 PVC pipe is strong, rigid, and can handle pressure applications. For jobs that require a higher pressurization though, schedule 80 pipe is better suited.
As per estimation, schedule 40 1.5 inch diameter PVC pipe can take 954 pounds of tensile strength, and schedule 80 1.5 inch diameter PVC pipe can take 1225 pounds of tensile strength. Tensile strength is simply the most weight that can be put on something before it breaks.
PVC pipe and fittings will sink.
In PVC pipe , the inside diameter is what changes. Both schedule 40 and 80 pipe have the same outside diameter. In PVC fittings, it is the outside diameter that changes. Both schedule 40 and 80 fittings have the same inside diameter.
PVC , because of its high chlorine content, creates toxic pollution in the form of dioxins, which accumulate in animals’ fat up through the food chain. Exposure to PVC often includes exposure to phthalates, which may have serious health effects.
Schedule 40 is the most common PVC type. Schedule 80 PVC is thicker and stronger, which enables it to handle higher pressures. Usually, PVC is only used for cold water pipes since hot water can eventually break down the plastic material . It can also degrade when exposed to the heat and UV rays of the sun.
PVC is made in several different grades: schedules 40 and 80 and chlorinated polyvinyl chloride ( CPVC ). Their uses are as follows: Schedule 40 is most commonly used for drain-line piping under houses.

PVC ( polyvinyl chloride) and UPVC (unplasticized polyvinyl chloride ) are two types of vinyl. PVC is often used to make siding and fences, whereas UPVC is used for window and door construction. PVC is not suitable for window and door construction due to its chemical composition.
