PIP VESSM001

This Practice provides requirements for the construction of a small pressure vessel or heat exchanger, both with limited design conditions.This Practice describes the general requirements for the design, materials, fabrication, examination, inspection, testing, certification and pressure relief of:

a. Three classes of small pressure vessels

b. Heat exchangers with the limited design conditions shown in Table 1a or 1b of this Practice

This Practice is applicable to:

a. The standard, pre-designed pressure vessels and heat exchangers supplied as part of pre-engineered package units (e.g., refrigeration and air-compressor systems)

b. Off-the-shelf vessels and exchangers

c. Vessels (e.g., filters) or exchangers built from the Manufacturers standard parts

For purposes of this Practice, it is understood that the term vessel includes heat exchangers.

This Practice is not intended for the following:

a. Vessel in Lethal Service (as defined in Section VIII, Division 1 of the ASME Boiler and Pressure Vessel Code (Code))

b. Vessels for which design wall thickness is governed by loadings from wind pressure or earthquake forces

c. Custom shell-and-tube heat exchangers outside the scope of Table 1a or 1b.
