How is iron pipe size measured?
To find it, measure around the circumference of the pipe with flexible measuring tape. Divide the circumference by pi, or about 3.14159. For example, if the circumference is 12.57 inches (319 mm), you would divide by pi, and get an outside diameter of about 4 inches (100 mm).
What is the outside diameter of 1/2 inch black iron pipe?
SCH 40 Bare & Black Standard Steel Pipe

|---|---|---|
| SCH 40 Pipe-3/8 | 3/8 in | 0.675 in |
| SCH 40 Pipe-1/2 | 1/2 in | 0.840 in |
| SCH 40 Pipe-3/4 | 3/4 in | 1.050 in |

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 measure a metal pipe?
How to Check the Diameter of a Metal Pipe
- Direct Diameter measurement is the easiest. Measure at the end of the pipe.
- Direct Diameter measurement with a caliper (useful if the end is not accessible) 1 1/2″ pipe.
- Measure circumference using a flexible tape and divide the outside circumference by 3.1415.
How do you read pipe sizes?
OD and Nominal Pipe Size
Tubing is measured by the OUTSIDE DIAMETER (O.D.), specified in inches (e.g., 1.250) or fraction of an inch (eg. 1-1/4″). Pipe is usually measured by NOMINAL PIPE SIZE (NPS).
How do you cut black galvanized pipe?
To cut galvanized pipe, use either a tube-cutting tool, a reciprocating saw, or a hacksaw. To use a tube-cutting tool, you’ll secure the vice-like tool around the pipe, then tighten it until it cuts through the pipe. Once you cut it, you’ll need to use a rounded file to sand down any burrs.
How do you calculate the flow diameter of a pipe?
The equation for pipe diameter is the square root of 4 times the flow rate divided by pi times velocity. For example, given a flow rate of 1,000 inches per second and a velocity of 40 cubic inches per second, the diameter would be the square root of 1000 times 4 divided by 3.14 times 40 or 5.64 inches.
What is the outside diameter of a 4 inch cast iron pipe?
Service Cast Iron

What is the outside diameter of 1 inch iron pipe?
Pipe Data – Steel – Iron Pipe Size (IPS)
| Nominal Pipe Size Inches | Nominal Pipe Size mm | Outside Diameter Inches |
|---|---|---|
| 1/2″ | 15 | 0.84 |
| 3/4″ | 20 | 1.05 |
| 1″ | 25 | 1.315 |
| 1-1/4″ | 32 | 1.66 |
Is iron pipe thread the same as NPT?
A tapered thread standard that is used for connecting various sizes of rigid pipe. This standard may be referred to as tapered iron pipe thread (TIPT), National pipe thread (NPT), iron pipe thread (IPT), or iron pipe standard thread (IPS).
What kind of threads are on black pipe?
Steel pipe comes in 21′ threaded pipe joints. The pipe has NPT threads on both ends and a coupling on one end making a full joint mipt x fipt overall. Cut lengths won’t include a coupling; if you need one, you should order one.
Is pipe measured by inside or outside?
diameter
All plastic pipe is measured on the outside diameter of the pipe, not the inside diameter. This is because the pipe needs to fit into the socket. The pressure rating of the pipe has no significance.
How do you find the outside diameter of a pipe?
Measure or calculate the outside circumference of the pipe. Then divide that amount by pi, usually rounded to 3.1415. The result is the outside diameter of the pipe.
Are pipes measured by diameter or circumference?
Pipe goes by nominal sizes rather than actual measurements which can be confusing. Copper 3/4-inch pipe, for instance, doesn’t measure 3/4-inch. Its outside diameter (OD) is 0.875 inch and inner diameter (ID) is 0.811 inches for Type M pipe (a designation that relates to 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).
What do you cut ductile iron pipe with?
Safety Tip: Some contractors use the K12 saw to both cut the pipe and bevel it. This may be faster than tracking down a generator and a grinder, but McWane Ductile recommends using the proper tool for the job. Pro Tip: Cutting Ductile iron pipe with the K12 saw will add to your overall installation time.
Can you torch ductile iron pipe?
While you can cut cast iron with a plasma cutter torch, torch use is not the best method to cut cast iron. When cutting cast iron, it is best to use a snap cutter, angle grinder, or reciprocating saw.
