This Practice provides requirements and details for the design and installation of steam tracing systems. This Practice describes minimum requirements for design, materials of construction, installation, leak testing, and inspection of steam tracing systems for process fluids that require heating to prevent condensation, freezing, unacceptable viscosity, crystallizing, separation, or temperature control. This Practice provides requirements for equipment, piping, and instruments for steam tracing including steam supply piping, steam tracers, tracer traps, and condensate collection.

This Practice provides requirements for installation of refractory brick (firebrick) linings. Installation methods include preparation, laying, and repair of the firebrick linings. This Practice also describes requirements for firing firebrick linings, when required.

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 tube 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, TEMA Standards of the Tubular Exchangers Manufacturers Association, 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 tube heat exchangers 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 tube heat exchangers that 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) shall be specified on purchaser’s PIP VEDST003 Data Sheet.

This Practice provides data forms and the associated instructions for specifying requirements for shell and tube heat exchangers constructed in accordance with TEMA, Standards of the Tubular Exchangers Manufacturers Association, and American Society of Mechanical Engineers Boiler and Pressure Vessel Code, Section VIII, Division 1 or Division 2, henceforth referred to as the Code. Requirements that are specific to Code, Section VIII, Division 2 are shown in braces . This Practice contains one data form for providing requirements for shell and tube heat exchangers having internal design pressures equal to or greater than 15 psig (103 kPa) and/or full vacuum external pressure at the top of the exchanger in its normal operating position, and are welded, shop- and field-fabricated, and in accordance with the requirements of the Code, Section VIII, Division 1 or Division 2. This Practice is required to be used with PIP VECV1001, PIP VESV1002, PIP VECST001, and PIP VESST002 to specify information necessary for the manufacturer to design and fabricate a shell and tube heat exchanger.

This Practice provides requirements for suppliers providing hygienic stainless steel check valves included in PIP Piping Line Class Material Specifications. For the purposes of this practice, “Hygienic,” “Process,” or “Hygienic Process” refers to all Hygienic Processes for Food/Beverage/Consumer & Current Good Manufacturing Practices (CGMP) or other products requiring a clean design.

This Practice provides requirements for suppliers providing hygienic stainless steel ball valves included in PIP Piping Line Class Material Specifications. For the purposes of this practice, “Hygienic,” “Process,” or “Hygienic Process” refers to all Hygienic Processes for Food/Beverage/Consumer & Current Good Manufacturing Practices (CGMP) or other products requiring a clean design. Ball valves are most often used in utility systems, such as clean gas flow, steam, water, etc., that support hygienic processes; however, it is highly recommended to avoid use of ball valves in the hygienic process. If necessary, it is recommended that any product contact ball valves are designated as “Clean Out of Place (COP)” to prevent cross contamination between products and batches.

This Practice provides a system for engineers to identify abbreviated piping terms and acronyms used in PIP piping Practices. This Practice establishes the definitions and interpretations for all piping-related abbreviations and acronyms used in piping Practices. Abbreviations for technical societies, codes, standards, etc., are not included.
