In an effort to provide you with 24-hour access to critical pipe data, we have established the following charts. Simply scroll down to the appropriate schedule and you should find all the relevant information regarding the pipe in question.

Nom Size is the nominal (name) size of the pipe. This is what you'd traditionally refer to when ordering pipe or pipe nipples or fittings.

OD is the outside diameter of pipe and pipe nipples. This number does not change based on the schedule.

ID is the inside diameter, and it will vary from schedule to schedule within the same size.

Wall is the measured wall thickness. Subtract the ID from the OD of any given pipe to determine Wall Thickness.

Wt/ft is Weight (in pounds) per Foot; a 12" pipe nipple should weigh this much, allowing for variances as called for within the pipe specifications.

ID Area is Inside Diameter Area, a Square-Inch measurement of the size of the hole.

GPM is Gallons Per Minute. This is measured assuming that the fluid or gas is being moved at a rate of 10 feet per second (10'/sec).

WPsi is Working PSI. This is the measurement of how much pressure the pipe can handle on a regular basis. While most pipe can handle brief surges above this, it is recommended that you select pipe which is capable of handling more than your working pressure, so that surges do not bring the pressure above the rated WPsi.
