operational efficiency in machine design and mechanical production. ASME issued its first standard, Code for the Conduct of Trials of Steam Boilers, in 1884. This paper evolved into Rules for the Construction of Stationary Boilers and for Allowable Working Pressure—the first edition of …Learn More
steam is circulated through a closed-loop piping system to transfer heat and/or humidity to a process. If you have processes that require different steam pressures and tempera-tures within your system, you can use pressure reducers to modify the pressure of the steam for specific pieces of equip-ment.Learn More
Jun 28, 2005 · The piping attached to the steam discharge flange must also be built to withstand the MAWP that the boiler can generate. In multiple boiler installations, the design rules typically apply to all piping through the second stop valve from the discharge flange of the boiler and are governed by ASME Code Section I and B31.1.Learn More
NOTE: The velocity ranges shown in Steam Pipe Capacity Tables 45-1 through 46-4 can be used as a general guide in sizing steam piping. All the steam flows above a given colored line are less than the velocities shown in the tables. Pipe Sizing Two principal factors determine pipe sizing in a steam system: 1. The initial pressure at the boiler andLearn More
2. Water (including fire protection systems), steam, steam-condensate, boiler feed water, and Category D fluid services, as defined in ASME B31.3. b. Classes of piping systems that are excluded or optional are as follows: 1. Piping systems on movable structures covered by jurisdictional regulations, including piping systems onLearn More
