本规程规定了买方用于确定设计标准的要求，包括根据ASME锅炉及压力容器规范第八节第1部分或第2部分（以下简称规范）和PIP VECV1001建造的壳式和板式热交换器的设计、结构材料、检验和测试。规范第八节第2部分特定的要求用大括号{}表示。本规程规定了由制造商设计和制造的壳式和板式热交换器的采购要求。 本规程还为满足规范第八节第1部分{或第2部分}和PIP VECV1001的原理和要求的新型壳式和板式换热器施工采购规范的制定提供了指导。对于某些换热器的采购，买方可将本规程和PIP VECV1001中的某些要求指定给制造商。指定的具体要求（如热设计和性能等级）可在买方的PIP VEDSP003数据表中规定。

This Practice provides requirements for use by a Purchaser for determining the design criteria including design, materials of construction, inspection and testing for shell and plate heat exchangers constructed in accordance with ASME Boiler and Pressure Vessel Code, Section VIII, Division 1 or Division 2, henceforth referred to as the Code, and PIP VECV1001. Requirements that are specific to Code, Section VIII, Division 2 are shown in braces { }. This Practice provides requirements for purchasing shell and plate heat exchangers that are to be designed and fabricated by a Manufacturer. This Practice also provides guidance for the development of purchase specifications for the construction of new shell and plate heat exchangers which meet the philosophy and requirements of Code, Section VIII, Division 1 {or 2} and PIP VECV1001.For some heat exchanger purchases, certain requirements in this Practice and in PIP VECV1001 may be assigned by Purchaser to Manufacturer. The specific requirements assigned (e.g., thermal design and the performance rating) can be specified on Purchaser's PIP VEDSP003 Data Sheet.
