Published Mar 25, 2026

CPVC Schedule 40 pressure pipe has an upper working temperature limit of 200°F (93°C) and has longer support spacing than PVC Schedule 40 pipes. Schedule 40 CPVC systems can be found in water and wastewater treatment, hot chemical drainage and plating applications, amongst others.

Is Schedule 40 PVC or CPVC?

Both come in Schedule 40 and Schedule 80 thickness. Schedule 40 PVC also comes in Class 125 fittings. PVC is available in 10 ft and 20 ft lengths. CPVC is available in 10 ft and 20 ft lengths.

What is meant by Schedule 40 pipe?

Here are a few examples of this: Pipe size 1.000” Schedule 40 – The actual wall thickness is 0.133” or 3.378 mm. Pipe size 1.000” Schedule 80 – The actual wall thickness is 0.179” or 4.547 mm. Pipe size 2.000” Schedule 40 – The actual wall thickness is 0.154” or 3.912 mm.

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

Schedule 80 pipe is designed with a thicker wall. This means the pipe is thicker and stronger, and as a result it can handle higher pressures. … 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.

What's the difference between Schedule 40 PVC and regular PVC?

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.

Do PVC and CPVC have the same OD?

80 PVC and sch. 80 CPVC will fit together because they have the same ID and OD. The same is true of schedule 40 PVC and CPVC, but that type of CPVC is rarely used. One major difference between these two types of piping, when it comes to sizing, is the fact that CPVC is made in two different sizing systems: NPS and CTS.

Can I use PVC instead of CPVC?

We recommend the use of PVC for recreational use/building, cold water systems, vent systems, and drainage systems. CPVC is recommended for applications where the maximum temperature will exceed 140 degrees Fahrenheit, but stay under CPVC’s max rating of 200 degrees Fahrenheit.

Is Schedule 80 PVC the same as CPVC?

Schedule 80 refers to the thickness of the pipe, and CPVC refers to the chemical makeup of the pipe. Therefore, schedule 80 CPVC is able to tolerate the PSI levels of schedule 80 PVC, which vary depending on the size of the pipe, while handling the temperatures of CPVC (200⁰ F).

Is Schedule 40 or 80 thicker?

Water Pressure for Sch 40 vs Sch 80 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).

Is CPVC always Schedule 80?

The thickness of a CPVC pipe wall is defined by the ASTM F441 Standard Specification for Chlorinated Poly(Vinyl Chloride) (CPVC) Plastic Pipe, Schedules 40 and 80, and is dependent on the outside diameter of a pipe. … Corzan® CPVC pipe and fittings are available in schedule 40 and schedule 80 nominal pipe sizes (NPS).

Why is it called Schedule 40?

They devised “Schedule” numbers as designating “the wall thickness in that pipe diameter that would hold a given pressure for a given material tensile strength”. So the pipe thickness which would hold 600psi at 15 ksi material strength was designated as schedule 600/15= 40.

What class is schedule 40 pipe?

Standard (STD), Extra Strong (XS) and Double Extra Strong (XXS). For PVC pipe, STD is schedule 40, XS is considered schedule 80 and XXS is a bit more undefined but generally considered schedule 120. Anything above schedule 80, however, is considered Double Extra Strong.

What is CPVC plumbing?

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.

Is Schedule 40 PVC safe for potable water?

Most schedule 40 PVC found in homes and offices is white pipe with a National Sanitation Foundation (NSF) rating for potable water. Both materials are considered safe for potable water. …

Can I use Schedule 40 PVC for drain?

Schedule 40 is ideal for above-ground vent lines and sewer lines in homes and has a thinner wall thickness than schedules 120 and 80.

What is the difference between white and GREY PVC?

Grey PVC is used as electrical conduit and is better suited for sunlight resistance. The fittings for this type of pipe are made to pull wires into and not intended for containing pressured fluids. White is for plumbing applications. Both use the same solvents and glues.

Which pipe is better CPVC or UPVC?

UPVCCPVCUPVC is not used for the purpose of drinking water transmission.CPVC is suitable for the purpose of drinking water transmission.UPVC is rigidCPVC is flexible

Which pipe is better PPR or CPVC?

1. Physical Properties. With 60% greater tensile strength and nearly twice the flexural strength, CPVC is a stronger, more durable piping material than PP R. Due to its strength, CPVC can withstand more pressure, which means same flow rate with smaller pipes.

Is CPVC good for plumbing?

Studies have proved that CPVC tubing and fittings are completely safe for home water supplies. In fact, CPVC has been successfully used in homes for more than 35 years. Be aware that many home copper or steel water pipe systems are used as grounding for electrical wiring.

Is CPVC the same as Schedule 40?

CPVC was designed as a replacement for copper plumbing tubing, with a water-potable and less-expensive plastic solution. … Since CPVC pipe uses a different measurement system and is smaller than their Schedule 40 counterparts, it is not compatible with FORMUFIT fittings and accessories.

Is CPVC the same as CTS?

CTS stands for Copper Tube Sizing. This is different from other PVC or CPVC pipes, which commonly use NPS, or Nominal Pipe Size, dimensions. … CPVC CTS pipe is used for hot and cold water distribution in pressure systems that do not exceed 180 degrees Fahrenheit.

Is CPVC measured ID or OD?

No. CPVC is measured by O.D., which makes its sizing similar to hard copper. PVC is measured by I.D., which makes its sizing similar to iron pipe.
