​This Practice describes the requirements for design, manufacture, inspection, testing, and shipping of three-phase liquid-immersed power transformers with a rating of 500 kVA and above in accordance with applicable International Electrotechnical Commission (IEC) standards.​

​This Practice provides a checklist for use by individuals responsible for ensuring the quality and completeness of an insulation job. This Practice describes the requirements for inspecting insulation by providing an Insulation Inspection Checklist, PIP INTG1000-F. The checklist is designed to apply to both cold and hot insulation systems as well as large-scale projects and individual items. As a result, there are specific items on the checklist that may not apply to all projects. Each section has a line for ranking workmanship. Because workmanship is somewhat subjective, ranking is provided. Comment sections are provided where appropriate. This Practice assumes that individuals charged with making the inspections are experienced in the design and installation of insulation systems and are well-acquainted with PIP Insulation Practices. The checklist does not provide sufficient information to act as a stand-alone document that would allow an inexperienced person to function as an inspector.​

​This Practice describes the design, inspection, testing, shipment, and documentation for valve-regulated lead-acid (VRLA) batteries for application in electrical stations, uninterruptible power supplies (UPS), or other applications located in indoor, non-classified areas. ​​​

​This Practice describes the minimum requirements to fabricate or install supports for large and small bore piping. The details provide dimensional and engineering requirements for the design of pipe supports. However, the suitability of all supports must be verified prior to use in any application. This practice is not a substitute for competent engineering analysis and design based on the specific requirements of each project.

​This Practice provides fabrication and installation details for piping vents, drains, and instrumentation connections including a. Hydrostatic Test Vents b. Hydrostatic Test Drains c. Valved Vents d. Valved Drains e. Pressure Connections f. Thermowell Connections g. Orifice Flange Tap Connections h. Steam Drip Stations Cross reference Table 1 Piping and Table 2 Pipeline are provided to relate the vent, drain, and instrument connection details to associated PIP Piping Material Specifications (PMSs) for Piping and Pipeline Systems. Cross reference Table 3 is provided to relate the steam drip station details to associated PIP Piping Material Specifications for steam service. ​​​​

​This Practice provides the minimum Positive Material Identification (PMI) requirements to ensure that only the alloy materials specified in the contract documents are provided in equipment, equipment internals, piping and piping components, and weld consumables.
