What do the numbers on PVC pipe mean?
Class number for PVC pipe denotes its pressure rating; examples are Class 315, Class 200, Class 160, Class 125, etc. This “pressure class” distinction tells you that the pipe is designed to withstand normal pressures of 315 psi, 200 psi, 160 psi, 125 psi, etc.
Are all PVC Fittings Schedule 40?
There are two main types of PVC fittings & pipe, schedule 40 & schedule 80. 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.
Is PVC pipe measured by ID or OD?
PVC Pipe is identified by the ID (Inside Diameter) and is referred to as a “nominal” size which means “in name only.” However this confuses people and most novices try to use the OD (Outer Diameter) to order parts. If you do this, measure the OD of your pipe and find it the 2nd column of the chart below.
Is PVC a CTS or IPS?
At this point, you’ll most often come across rigid piping in Nominal (rigid copper piping falls under this), IPS (PVC, galvanized and stainless steel all fall under this) and CTS (Copper Tubing Size – soft copper tubing and some styles of CPVC fall under this). Most rigid pipe is identified by IPS type sizing.
Is pipe measured ID or OD?
In short: Tube is measured by outside diameter, pipe is measured by inside diameter. There is often confusion as to which size die the customer actually needs – Pipe Size or Tubing Size. Keep in mind that pipe size refers to a nominal – not actual – inside pipe diameter. Schedule refers to the pipe’s wall thickness.
How do you determine your fitting size?
You can always identify AN fittings based on the male thread size (outside diameter). These sizes are constant regardless of brand, hose type, or fitting configuration. If your fitting has a convex 37 degree flare at the end, the threads will tell you the AN size (and vice-versa).
How do you read PVC pipe numbers?
If you purchased your PVC pipe from a hardware store, you can use the markings on the side of the pipe to tell you what size you have. It will normally indicate the size in decimal or fraction, close to where the manufacturer’s name is, such as ‘1.25’ (for 1-1/4″) or “3/4” (for 3/4″… obviously).
What is difference between schedule 40 and 80 PVC?
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 is the ID of 4 inch PVC pipe?
| PVC and CPVC Pipes – Schedule 40 | ||
|---|---|---|
| Nominal Pipe Size (inches) | Outside Diameter (inches) | Inside Diameter*) (inches) |
| 3 | 3.500 | 3.068 |
| 4 | 4.500 | 4.026 |
| 5 | 5.563 | 5.047 |
How big of a fitting do I need for PVC pipe?
Pipe Fittings Sizes. As mentioned in a previous blog post about PVC pipe outer diameter, PVC pipe and fittings use a nominal system for standard sizing. This is so all parts with the same size in their name will be compatible with each other. All 1″ fittings will fit on 1″ pipe, for example.
Which is the best way to identify PVC pipe?
Method #1 is represented by the light blue panels, and Method #2 is represented by the light green panels. Those are the two data points you need to know to identify your pipe. If using method #2, the only sure fire way to do this is buy a digital caliper.
How are couplings used in PVC pipe fittings?
They can also be used to divide fluid flow in different directions. Couplings are one of the most simple (and inexpensive) types of PVC fittings. They are a small part that connects or “couples” one part to another, usually permanently. They can connect pipe to pipe and pipe to fitting.
Can you use compressed air to test PVC pipe?
PVC Schedule 80 Pipe Testing with or use of compressed air or gas in PVC / ABS / CPVC pipe or fittings can result in explosive failures and cause severe injury or death. • NEVER test with or transport/store compressed air or gas in PVC / ABS / CPVC pipe or fittings.
