Both schedule 40 and 80 PVC are used widely around the world. Each one has its benefits in different applications. Schedule 40 pipe has thinner walls, so it is best for applications involving relatively low water pressure. Schedule 80 pipe has thicker walls and is able to withstand higher PSI (pounds per square inch).

What are the schedules of PVC pipe?

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.

What is Schedule 40 PVC pipe used for?





PVC Schedule 40 pipe is used for drainage and lower pressure water flow applications. Schedule 40 PVC pipe can handle up to 140 degrees F in temperature. Pipe lengths come in standard 10′ or 20′ sections. PVC schedule 40 pipe is available in plain end or belled end that do not require coupling for installation.

What is Schedule 20 PVC pipe used for?

SCHEDULE 20 PVC PIPE



The wall of the pipe is much lighter than that of Schedule 40, and must only be used in situations where vehicles, traffic, or any other type of equipment crossing the area will not be a factor. The outside diameter is the same as SDR 35, and is compatible with all Schedule 20 and SDR 35 fittings.

What is Schedule 80 PVC pipe used for?

What is schedule 80 PVC used for? Because schedule 80 PVC is a thicker pipe, it is usually is used for applications that are commercial or industrial in nature. These more demanding applications generally require piping that will stand up to high pressures and harsh environments.

What is the difference between Schedule 20 and Schedule 40?

Quote from the video:
Quote from Youtube video: It's typical for the schedule. 20 sometimes it's called sewer and drain pipe um it's typical for that to be used in the drain field itself. But not from the house to the tank.

What is Schedule 40 and Schedule 80 pipe?





The major difference between schedule 40 and schedule 80 pipe is the wall thickness, inside diameter, and their weight. Schedule 80 will have a greater wall thickness, a smaller inside diameter and a higher weight than Schedule 40 pipe at a given nominal pipe size.

What is Schedule 120 PVC pipe used for?

high-pressure

Generally, schedule 120 is used in high-pressure or industrial applications. On the other hand, schedule 80 PVC is ideal for applications that require a higher rating in terms of pressure as necessitated by plumbing codes than what schedule 40 is capable of handling.

What is the difference between PVC Schedule 40 and Schedule 80?

Schedule 40 PVC is usually white in color and has thinner walls, thus can handle less pressure than it’s counterpart. Schedule 40 PVC pipe works best for low water pressure applications. By contrast, Schedule 80 PVC is usually gray in color and has thicker walls; therefore, it can handle higher water pressures.

What is GREY PVC used for?



The most noticeable difference between regular PVC and electrical PVC is the color of the pipes. PVC pipe that is used for plumbing is usually white while electrical conduit PVC is usually gray.

What does Schedule 40 mean?

The most used pipe schedule is SCH 40. For NPS 12 or smaller pipes or pipes with outer diameter of around 12 inches, SCH 40 is the same wall thickness of the previously used value. The SCH 80 wall thickness, on the other hand, is the same as the previously used XS wall thickness for pipe sizes up to NPS 10.

What is class 200 PVC pipe used for?

PVC Class 200, 160 and 125 pressure pipe are used in rural water systems, agricultural and turf irrigation and as sewer force mains.

Can Schedule 40 PVC be used for water supply?



Most schedule 40 PVC found in homes and offices is white pipe with a National Sanitation Foundation (NSF) rating for potable water. The drawbacks with this type of PVC pipe are that it will degrade when exposed to short wave UV light (contained in sunlight) and at higher temperatures, it will soften.

What PVC pipe is used for hot water?

CPVC

CPVC (schedule 80) pipe is rated for use up to 200 degrees Fahrenheit. This makes it ideal for use on hot water lines in homes and businesses.

What is Schedule 80 CPVC pipe?

CPVC Pipe is used in corrosive resistant applications. Pipe ranges from 1/8” to 24” in size and can be used in applications reaching as high as 200°F. Pressure ratings change on the pipe with size, the schedule of the pipe and the temperature that the pipe will be under.

Is Schedule 80 PVC safe for drinking water?



Westlake Pipe & Fittings Schedule 40, Schedule 80 and insert fittings are listed with the National Sanitation Foundation (NSF) for use in potable water applications and comply with Standard 14 and 61.

What is CPVC used for?

Overview. CPVC is a high-temperature plastic pressure piping system introduced for potable plumbing in 1959. It has also been used extensively in fire sprinkler systems since 1985. This material is also used for many industrial and process piping applications.

Can GREY PVC be used for water?

Gray conduit is not rated for pressure pipe applications and may not be suitable for potable water use. Stabilizers and other ingredients used in conduit PVC may be toxic; conduit PVC is not held to the same drinking water standards as NSF marked pipe and should not be used in potable water systems.

What pipe is safe for drinking water?

Copper pipes with lead-free joint materials are the best choice for water pipes. They are long-lasting and won’t leach chemicals into your drinking water. However, copper pipes are generally more expensive, and copper’s intensive extraction and manufacturing process presents some environmental trade-offs.

Is PVC OK for drinking water?



Plastic piping started to become common around the same time as copper, principally PVC, CPVC, and PEX. All of these plastics are approved for use in freshwater lines and shouldn’t present health hazards for your household.

Is CPVC safe for water?

CPVC (chlorinated poly (vinyl chloride) is a strong and rigid thermoplastic material that is used for hot and cold potable water applications in residential construction. Because of its makeup, CPVC is immune to damage from highly chlorinated domestic water and has a higher temperature tolerance than PVC.
