Process Flow Diagram Documentation Guideline (Universally Applicable)

Abstract ↓

This Practice provides general guidelines for the development of Process Flow Diagrams (PFDs) for process and utility systems. This Practice covers the development of new PFDs and does not apply to existing PFDs developed before the adoption of this Practice. The Practice applies to all diagrams that fit the definition of a PFD in Section 3. This Practice can be applied to any CAD (computer aided design) system used for developing PFDs and is not vendor-, hardware-, or software-specific. Although this Practice provides general guidelines for the development of PFDs, individual applications may require differing approaches than those recommended in this Practice. Determinations concerning fitness for purpose and matters of application of the Practice to a particular project or engineering situation should not be made solely on the information contained in this Practice. Example PFDs in the appendixes of this Practice are not intended to recommend specific design details or requirements but are included to provide illustrations of various options available to the user.

Abstract ↓

This Practice provides requirements for use by a purchaser for determining the design criteria for pressure vessels constructed in accordance with ASME 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 describes the requirements for the design, materials of construction, inspection and testing of pressure vessels constructed in accordance with Code, Section VIII, Division 1 {or 2}. Guidance is also provided for the development of purchase specifications for the construction of new pressure vessels which meet the philosophy and requirements of Code, Section VIII, Division 1 {or 2}.

This Practice also applies to bulk solids product containers, electric immersion process heaters, shell and plate exchangers, shell and tube exchangers, and air-cooled exchangers. See PIP VECBI001 and PIP VESBI002 for the additional requirements specific to bulk solids product containers only. See PIP VESEH001 for the additional requirements specific to electric immersion process heaters only. See PIP VECSP001 and PIP VESSP002 for the additional requirements specific to shell and plate exchangers only. See PIP VECST001 and PIP VESST002 for the additional requirements specific to shell and tube exchangers only. See PIP VESAC001 for the additional requirements specific to air-cooled exchangers only.

This Practice is intended to be used for the purchase of vessels where the manufacturer is also responsible for performing detailed design for the vessels in accordance with the Code and PIP VESV1002. If purchaser also performs a detailed design, the design shall also be in accordance with PIP VESV1002. The following are not covered by this Practice:

a. Standardized pre-designed (i.e., off-the-shelf) vessels (see PIP VESSM001)

b. Vessels with layered construction

c. Small vessels and low-pressure vessels (see PIP VESSM001 and PIP VESLP001)

d. Process design of trays and other removable internals

PCCCS005

Secure Remote Access to Industrial Process Control Systems

Abstract ↓

This practice covers remote access to the Industrial Control System (ICS) environment in a secure fashion. Once connected to systems in the process network, the access allowed is beyond the scope of this Practice. It is best practice to use multiple accounts for different purposes; a control system engineer might have universal access while a vendor/third party account would be restricted to only their equipment/information. Such accounts and their capabilities are beyond the scope of this Practice.

PEEPR002

Class of Plant (Universally Applicable)

Abstract ↓

The purpose of this Practice is to assign a Class of Plant classification to project Performance Categories to achieve the right balance of life, cost, and asset utilization for any types of operating facilities. This Practice is intended to be a tool to evaluate a project under development or to determine if the current design is fit for purpose. This process should begin early in the design process to establish the design plan and expectations with management and stakeholders. It is critical that choices made during a Class of Plant evaluation do not compromise safety. The intent of a Class of Plant exercise is to align business objectives with engineering objectives through robust and cost-effective solutions.

A facility may have different classes assigned across distinct performance categories. For example, a temporary facility may be Class 1 for Performance Category Life and Class 4 for Performance Category Instrumentation. Class of Plant can be a tool used during value engineering exercises to determine appropriateness of the project scope.

RESP73V

Application of ASME B73.2-2023 Specification for Vertical In-Line Centrifugal Pumps for Chemical Process

Abstract ↓

This Practice supplements ASME B73.2-2023, Specification for Vertical In-Line Centrifugal Pumps for Chemical Process. Together, this Practice and ASME B73.2-2023 provide requirements to the manufacturer for design and manufacture of vertical in-line centrifugal pumps.

This Practice describes additions, changes, and/or deletions to the requirements in ASME B73.2-2023. The section/paragraph numbers and the associated headings used in this Practice correspond to those used in ASME B73.2-2023. Because this Practice does not take exception to all the requirements in ASME B73.2-2023, the section/paragraph numbers in this Practice may not be sequential.
