PIP VESSM001

This Practice describes the general materials, design, fabrication, examination, inspection, testing, and documentation requirements for pressure vessels with limited design conditions. This Practice designates minimum general requirements for the construction of three classes of small pressure vessels (including heat exchangers) with the limited design conditions shown in Table 1. See Section 5.3 for material of construction limitations. This Practice is intended to apply to the Manufacturer?s standard, pre-designed pressure vessels and heat exchangers supplied as part of pre-engineered package units (e.g., refrigeration and air-compressor systems), "off-the-shelf" items and vessels (e.g., filters) built from the Manufacturer's standard parts. Use of this Practice for custom-designed vessels is limited to applications that have been reviewed and approved in writing by the Purchaser. Special requirements are covered in the Vessel Specifications (see Section 3 for definition).
