Pipe Sizing for Air, Gas and Steam

These tools choose a pipe size. Enter the load or flow, pressure and run length for compressed air, gas or steam lines, and use the pipe schedule chart for outside diameter, wall, inside diameter and weight.

Tools in this group

• Compressed Air Pipe Sizing Calculator — Enter the air flow, operating pressure, pipe length and the pressure drop you can accept to get the smallest compressed air line size.
• Copper Pipe Dimensions Chart (Type K, L and M) — Choose the tube type and nominal size to read its outside and inside diameter, wall, weight and water volume, or print the full chart.
• Gas Pipe Sizing Calculator (Natural Gas and Propane) — Enter the appliance load in BTU/h, the longest run and the allowed pressure drop to get the gas line size, with a capacity chart computed from the published sizing equations.
• Pipe Schedule Chart and Pipe Size Lookup — Look up one pipe size and schedule for its outside diameter, wall, inside diameter, flow area and weight, or print the full chart.
• Steam Pipe Sizing Calculator — Enter the steam flow and pressure to get the pipe size and velocity, or switch to condensate load to size the steam trap capacity.
• Steam Table Calculator (Saturated and Superheated Steam) — Type a pressure or temperature to read the steam properties from the IAPWS-IF97 equations, or print a full saturated steam table.
