Pressure Vessels – Determining Wall Thickness

The following formulas are used in the ASME Code Section VIII, Division 1 for determining wall thickness: Wall thickness—cylindrical shells Figure 12-1 defines the various types of heads. Most production facility vessels use ellipsoidal heads because they are readily available, … Continue reading

Pressure Vessels – Maximum Allowable Stress Values

The maximum allowable stress values to be used in the calculation of the vessel’s wall thickness are given in the ASME Code for many different materials. These stress values are a function of temperature. Section VIII of the ASME Code, … Continue reading

Pressure Vessels – Design Pressure

The design pressure for a vessel is called its “Maximum Allowable Working Pressure” (MAWP). In conversation this is sometimes referred to simply as the vessel’s “working pressure.” The MAWP determines the setting of the relief valve and must be higher … Continue reading

Pressure Vessels – Design Temperature

The maximum and minimum design temperatures for a vessel will determine the maximum allowable stress value permitted for the material to be used in the fabrication of the vessel. The maximum temperature used in the design should not be less … Continue reading
