This Practice provides design criteria for fixed gas detectors installed in process areas to detect the presence of combustible, oxygen, or toxic gases. This Practice addresses combustible, oxygen, and toxic gas detectors permanently installed for ambient air monitoring (e.g., leak detection, oxygen depletion). The technologies included are catalytic bead, infrared, and electrochemical. This Practice does not cover portable gas monitoring equipment, process analyzers, or sampling systems. The systems used to perform data acquisition, alarming, and control action are not covered by this Practice because the solutions are diverse and can include stand-alone to advanced multisystem configurations.

This Practice provides the minimum requirements for design, procurement, and construction for clean rooms. A clean room is a room within which the number concentration of airborne particles is controlled and classified, and which is designed, constructed, and operated in a manner to control the introduction, generation, and retention of particles inside the room. Clean rooms may be procured as modular, pre-fabricated units, or constructed on site from materials selected to minimize generation of particles and to resist microbial growth over time. This Practice provides an overview of design considerations to complement the use of its associated data sheet.

This Practice covers minimum requirements for the maintenance of power cables. It is applicable for both low voltage (≤ 1000 volts) and medium voltage (> 1000 volts to < 100 kV) systems. It is intended for use on power cables of extruded dielectric insulation or laminated dielectric insulation. This Practice is intended for maintaining power cables used in distribution, transmission, etc. type applications. The maintenance of electric motor conductors is covered in PIP ELTFT02; however, this Practice may be used for the maintenance of motor conductors if approved by the owner’s AHJ. While this Practice is intended for the maintenance of power cables, the testing and assessment procedures described below can be applied to installation and acceptance testing. The test voltages and applied times will vary between the maintenance test and the other tests. Refer to the IEEE and NETA documents found in the Reference section below for these differences. This Practice does not cover testing of bare overhead conductors.

This Practice provides guidelines for selection, design, layout and installation of steam traps.

This Practice provides guidelines for specifying the requirements for examination and leak testing of metallic, lined metallic, and nonmetallic piping systems designed in accordance with ASME B31.3 Process Piping, hereinafter referred to as the Code. The requirements include examination of piping materials, components, fabrication, assembly, installation, and associated documentation. This Practice also covers the extent of examination, criteria for acceptance, and correction of defective work. It describes the types of leak tests, bases for selecting the appropriate tests, and arrangements for testing piping.

This Practice describes the minimum requirements for the structural design of process industry facilities at onshore sites. This Practice is intended to be used in conjunction with PIP ARC01015, PIP ARC01016, PIP CVC01015, PIP CVC01017, and PIP CVC01018, as applicable. This Practice does not include design criteria for loads associated with transportation or lifting of modular structures.

This Practice provides requirements for designing metallic piping systems to ASME B31.3, Process Piping (hereinafter referred to as the Code). This Practice provides requirements for piping systems arrangement, design conditions, components, and joints. This Practice shall be used in conjunction with the Code. The requirements of this Practice are more stringent than the Code for the purpose of standardization and not because the Code is considered unsafe. Piping systems designed in accordance with other piping codes are not included in this Practice.

This Practice provides the minimum requirements and policies regarding professional development hours (PDHs) issued by Process Industry Practices (PIP) for Professional Engineering licensees (PEs) participating in Continuing Education Programs (CEPs), to the extent required by respective state boards of licensure. PIP does not issue Continuing Education Units (CEUs).

This Practice describes the minimum requirements for design, fabrication, inspection, testing, shipment, and documentation for an electronically-controlled battery charger used for charging float-type batteries and simultaneously powering the connected utility system loads in indoor unclassified areas. This Practice does not apply to grounded DC systems.

This Practice describes the general design requirements and basis of design for electrical systems. This Practice includes requirements for system components and typical configurations.

This Practice describes the minimum requirements for permanently mounted, top-, bottom-, and side-entering mixers and agitators installed in pressurized or unpressurized vessels, with or without mechanical seals. This Practice does not cover requirements for portable and clamp-on light duty mixers or agitators, in-line mixers, jet-type mixers, or high-speed dispersers. The requirements in this Practice are modifications, additions, and/or deletions (exceptions) to the requirements in PIP RESM003 – Specification for Mixers and Agitators. The section/paragraph numbers and the associated headings used in this Practice correspond to the ones used in PIP RESM003. Because this Practice does not take exception to all the requirements in PIP RESM003, the section/paragraph numbers in this Practice may not be sequential.

This Practice describes the requirements for the certification and prequalification of ceramic fiber refractory materials used to construct refractory linings in fired heaters and other process equipment. It provides a basis for selection, purchase, and quality control of ceramic fiber refractory materials. Included are material property, testing, documentation, storage, packaging, and marking requirements for the following types of ceramic fiber refractories a. Alkaline Earth Silicate (AES) b. Refractory Ceramic Fiber (RCF) c. Polycrystalline Wool (PCW) This Practice does not include mineral wool, fiberglass, and other non-refractory fiber insulations, or rigid block refractory insulation materials.

This Practice provides the minimum requirements for ASME B73.1 pump baseplates and baseplates for general purpose pumps. This Practice describes minimum requirements for horizontal pump baseplates that are not covered in the API standards.

This Practice provides requirements for designers preparing Piping and Instrumentation Diagrams (P&IDs). This Practice describes the requirements for P&ID format and content. The Practice is independent of time in a facility life cycle and encompasses design, construction, operations, and maintenance. This Practice covers the generation of new P&IDs and does not apply to the revision of existing P&IDs. This Practice also applies to P&IDs provided by packaged equipment vendors. This Practice applies to all diagrams that fit the definition of a P&ID in Section 3. The requirements provided in this Practice can be applied to any CAD system used for developing the P&IDs and are not vendor, hardware, or software specific. This practice uses U.S. Customary units of measure for drafting dimensions. Line weights are also given in metric units. Current PIP experience is that symbol sizes and drafting dimensions are often based on U.S. Customary units even if the project design and labeling is in metric units. All drafting dimensions could be stated in metric units at the discretion of the user. The requirements provided in this Practice provide a balance between showing all data on P&IDs and making P&IDs legible and easy to read. Process specific overlays may be developed to define necessary additional requirements or exceptions. The example P&IDs included in the Appendixes of this Practice are not intended to recommend specific design details or requirements. Example P&IDs are included to provide an illustration of how the elements of this Practice are combined into a P&ID.vElectronic native files for the text, symbols, and legend sheets are available to PIP Member Companies for input to members’ CAD systems. Development of project-specific legend sheets is recommended using the PIP native files as a starting point. Additions and/or deletions are allowed to meet requirements. Legend sheet borders and title blocks can be altered. Development of P&IDs has historically been led by the petrochemical, oil & gas, and specialty chemical industries. While applicable to all industries, guidelines and practices have primarily focused on these industries. In this revision, we have expanded the scope to include information specific to developing P&IDs for the hygienic processing industries – pharmaceutical, food, and beverage. While Sections 2, 3 and 4 contain requirements for P&IDs across all industries, Appendix D contains content specific to the hygienic processing industry that supplements or replaces that in Sections 2, 3 and 4. If PIP membership grows to include other industries, it is anticipated that this Practice will expand to have sections on developing P&IDs for the mining, power, pulp and paper, and other industries.
