Line Pipe Schedule 100 Dimension, Weight and Thickness Chart

Oilfield Chart - Line Pipe Schedule 100 Dimension, Weight and Thickness Chart
Pipe Schedule (SCH) relates to the wall thickness of the pipe. As the wall becomes thicker, the schedule number increases. In other words, the wall size increases as the schedule number rises.

For example, Pipe Size 2.000 with Schedule 80 has 0.218 actual wall thickness.

Relationship among the Dimension Specifications

The outside diameter (mm), wall thickness, and weight increment, as the pipe nominal size increases, except for the outside diameter measured in inches.

Column Descriptions

The column of Line Pipe Schedule 100 Dimension, Weight, and Thickness specifies each of the values below:

Nominal size refers to the approximate inside diameter, sizes, and thickness. The nominal size of pipe in inches does not reflect the actual size. Nominal size is also a trade size used for trade descriptions. For instance, a pipe measured 2” nominal size is equal to 2.067 inches.

Outside Diameter (OD in inches) is the measurement of the pipe’s outer diameter. To calculate the OD:

OD = ID + Wall Thickness (2x)

The wall thickness stays the same for a given nominal pipe size.

Outside Diameter (OD in mm) is the OD in millimeter. As the nominal size increases, so does the outside diameter.

Wall thickness (inches and mm) is expressed in pipe schedule or SCH.

To calculate the wall thickness, here’s the formula:

(OD – ID) / 2

Where OD is the outside diameter and ID is the inside diameter

For instance, 5 – 2 /2 = 1.5

Subtract the outside diameter to the internal diameter and divide the result by 2.

Weight (lb/ft) (kg/m) refers to the weight per foot of any pipe wall thickness and size. The weight increases as the nominal size, outside diameter, and wall thickness increase.  The weight per lb/ft and kg/m increases as the pipe nominal sizes increase. To calculate, use the following formula:

Pipe weight = Volume = pi (internal diameter – external diameter) / cross-sectional area X length

Volume = (in meters) X (the equivalent unit of a specific metal type, for instance a unit of cast iron is 7200 kg/m3 while for steel it’s 7859kg/m3)
