## Is steel pipe measured by ID or OD?

actual outside diameter
SIZE: And regardless of its material, steel tube is measured by its actual outside diameter (OD). For instance, the diameter of a 1 ¼” tube is a true 1.25″, while a 1 ¼” pipe is 1.625″. The wall thickness of thinner tubing is measured by gauge while thicker tubing is measured in fractions or millimeters.

Is nominal pipe size OD or ID?

The nominal dimension for pipe is the ID. So, 1½ inch pipe is NOT 1½ inch outside diameter, but instead is nominally, (approximately) 1½ inch inside diameter.

### What is the OD of 3/4 galvanized pipe?

The OD of 1/2-inch galvanized pipe is about 7/8-inch and so is 1/2-inch PVC. 3/4-inch pipe measures 1-1/16 inches, 1-inch measures 1 5/16 inches and 1 1/4 inches measures 1 5/8 inches. These same rules apply to rigid copper plumbing. The outside diameter of 1/2″ copper measures 5/8″.

Is galvanized pipe measured by ID or OD?

To find the nominal size, you can measure the inside diameter of your pipe directly, or you can estimate the inside diameter by measuring the pipe’s outside diameter. When measuring from the outside, keep in mind that galvanized pipe comes in three weights with different wall thicknesses.

## What are the threads on a steel pipe?

Pipe has clockwise (right – hand) threads on one end and counterclockwise (left – hand) threads on the other end. When you use a wrench to turn, connections on both ends tighten at the same time. A plastic sleeve prevents destructive corrosion when connecting different metals. Assortments contain threaded pipe in various lengths.

## What kind of pipe fitting is schedule 80?

Also known as Schedule 80. Typically used with medium-pressure galvanized iron and steel threaded pipe fittings. Also known as Schedule 80. Typically used with high-pressure iron and steel threaded pipe fittings. Also known as Schedule 160. Typically used with high-pressure galvanized iron and steel threaded pipe fittings.

What kind of pipe is used for pipe fittings?

Typically used with high-pressure galvanized iron and steel threaded pipe fittings. Also known as Schedule 160. Typically used with thick-wall and high-pressure iron and steel unthreaded pipe fittings. Also known as Schedule 80. Typically used with extreme-pressure iron and steel unthreaded pipe fittings. Pipe is also known as Schedule XXH .

What kind of pipe is used for low pressure?

Also known as Schedule 40, this steel pipe is designed for low-pressure applications. Pipe has clockwise (right – hand) threads on one end and counterclockwise (left – hand) threads on the other end. When you use a wrench to turn, connections on both ends tighten at the same time.
