Practices by Discipline

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 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.

This Practice describes the requirements for the design, fabrication, inspection, testing, and shipping of factory-assembled low-voltage automatic transfer switches. This Practice does not cover fast transfer systems.

This Practice provides requirements and work process for ensuring consistency of style and presentation for Computer-Aided Drafting (CAD) associated with Process Industry Practices (Practices). This Practice provides detailed instructions for the Function/Task Team representative and CAD representative. This Practice does not apply to figures inserted in the narrative of a Practice.

This Practice provides guidelines for design engineers involved in design, fabrication, installation, and repair of anchorage for foundations and structures. This Practice supplements the ASCE Anchorage Design for Petrochemical and Other Industrial Facilities, hereafter referred to as the ASCE Anchorage Design Report. The information on fabrication, installation, and repair of anchorages provided in this Practice is to be used by design engineers to develop specifications, drawings, scopes of work, etc. for fabricators, constructors, and maintenance personnel involved in fabrication, installation, and repair activities.
