Practices by Discipline

​This Practice provides the minimum requirements for the specification of mechanical and controls functions, design and manufacturing of seat valves in hygienic processes. Mix-proof valve packaged systems may include a broad range of designs for process and Clean-in-Place (CIP) applications. This Practice is intended to address basic requirements that are typical for typical single seat and mix-proof valves. The purchaser shall ensure that specifications are invoked and provided for specific applications that exceed the scope of this Practice. The purchaser may also provide data sheets, P&IDs, process data, and any other supplemental specifications to define the requirements for specific packaged equipment. For the purposes of this practice, “Hygienic,” “Process,” or “Hygienic Process” refers to all hygienic processes for Food/Beverage/Consumer and Current Good Manufacturing Practices (CGMP) or other products requiring a clean design.​

​This Practice describes the general requirements for surface preparation, application, and inspection of architectural protective coatings utilized for substrates used in hygienic processes and facilities. For the purposes of this practice, “Hygienic,” “Process,” or “Hygienic Process” refers to all Hygienic Processes for Food/Beverage/Consumer and Current Good Manufacturing Practices (CGMP) or other products requiring a clean design.​

​This practice and the purchaser’s PIP ELSAP13-D Data Sheet describe the minimum requirements for design, fabrication, inspection, testing, shipment, and documentation for a complete on-line Battery Energy Storage (BES) system. This practice defines the general requirements for the charge and discharge characteristics, the inverter, the battery chemistry type to be utilized, and the BES enclosure. Specific requirements for battery chemistry (e.g., lithium-ion, molten salt, lead acid, etc.) are covered in separate PIP Practices.  ​

​This Practice describes the requirements for design, construction, performance, inspection, testing, shipment, and documentation of low-voltage (up to 600 volt input) AC, 3-phase, adjustable speed drives (ASD) for squirrel cage induction motors. This Practice does not include the motor requirements. If a coordinated package is required, the purchaser shall also include the motor specifications.​

​This Practice describes the requirements for design, construction, and testing for NEMA premium-efficiency, horizontal or vertical, polyphase squirrel cage induction motors that are 4000 volts and below, including hazardous (classified) areas.​

​This Practice describes requirements for design, fabrication, inspection, and testing of metal-enclosed, self-cooled, nonsegregated-phase bus duct assemblies for use on systems operating through 38 kV, and suitable for indoor and outdoor applications. This practice does not cover the requirements for solid dielectric (sandwich) type constructed bus duct.​

​This Practice provides guidance to engineers for the application of the PIP insulation Practices. This Practice describes how to use PIP insulation Practices and supporting documentation for the execution of a project. A general description of each Practice is provided. Instructions are provided for the use of the associated data forms.​

​This Practice describes the requirements for a grounding resistor assembly to be used in a 2.4 to 15 kV low resistance grounding system with a neutral available.​

​This Practice provides guidance for the design of insulation systems. It describes the types of insulation systems that are indicated by the type code on the Piping and Instrumentation Diagrams (P&IDs), data sheets, and other design documents. This Practice provides guidance on insulation design criteria, insulation materials, extent of insulation, determination of insulation thickness, and insulation material properties.​

​The purpose of this Practice is to provide guidance for completion of Pipe Weld Data Sheets, referred hereinafter as PWDSs. The basis for completion of the PWDSs is provided in the design specification documents and applicable construction code. This guidance document is primarily developed for use with ASME B31.3 piping fabrication. Although piping systems designed in accordance with other piping codes are not the primary focus of this Practice, it may be used for piping fabricated to other codes, including ASME B31.1, ASME B31.4, ASME B31.8, or other codes as applicable. The PWDS covers basic weld and quality control requirements for pressure retaining materials and attachment welds to pressure retaining materials. Other welding requirements are outside the scope of this Practice. A PWDS should be developed for engineering, procurement, construction or design-build (EPC) or design-build type of projects where either the owner or the owner’s engineer is responsible for the procurement and/or construction of shop or field fabricated pipe. Development and completion of PWDSs for projects should be undertaken for consistent quality control throughout construction and to provide a basis for inspection and construction cost basis to minimize fabricator or constructor interpretation of code and/or owner expectations. PWDS development is a necessary engineering activity for support of procurement and construction activities for fabricated pipe of any kind. A PWDS should be developed before construction and bidding activities where spool fabrication, field construction, or fabrication of equipment skid piping is required. The Pipe Weld Datasheet can be adapted to other fabrication activities where specific quality control requirements are necessary to provide an acceptable level of inspection or fabrication requirements. ​​

​This Practice contains the minimum requirements for design, manufacture, inspection, testing, and shipping of air-cooled dry type power transformers rated 750 kVA and above with primary voltage ratings less than or equal to 34.5kV.
