Some uses of PVC 40 pipe are for drain-waste-vent systems in plumbing. This means that the pipe is used to carry wastewater away from sinks, tubs and toilets and for conveying fresh hot and cold water into the building. It's also used for venting dangerous sewer gas from the toilets.
Because of its versatility, PVC 40 pipe must withstand heat and pressure. It is tolerant of heat up to 140 degrees Fahrenheit, which is somewhat higher than the temperature recommended to heat water for most houses. It is also has a pressure rating of from 120 pounds per square inch to 180 psi, which is more than enough to bring fresh water into buildings.
PVC 40 pipe also resists corrosion and holds up well when exposed to salt, most acids and bases. It also tolerates halogens, oxidants and aliphatic solutions. Aliphatic solutions are solutions of nonaromatic hydrocarbons such as butene and methane. PVC 40 is also fire resistant and is also used in chemical procedures, in irrigation and agriculture, and in industries that require the removal or transfer of corrosive liquids or gases.
PVC 40 pipe is made of rigid polyvinyl chloride, and the pipe sizes range from 1/8 inch to 24 inches in diameter.
