Velocity Rating – feet per second
Where single values appear in the velocity tables, these may be considered safe for water, steam, air or gas. In the shorter insertion lengths, consideration is given to the velocity pressure effect of water flowing at higher velocities. The values in parentheses, therefore, represent safe values for water flow, while the unbracketed values may be used for steam, air, gas and similar density fluids.
* Material – 304 SS, Carbon Steel, etc.
Pressure-Temperature rating–lb per sq. inch
