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.

RESP003V

Specification for High Power Vertical Centrifugal Pumps for Water Service

Abstract ↓

This Practice provides requirements for design and manufacture of vertical centrifugal pumps of 150 kW (200 HP) or greater used for water services.

Comment: General water services include condensate, cooling water, demineralized water, utility water, produced water, treated water, etc.

This Practice covers pumps with service conditions within the following limits:

a. Maximum discharge pressure 35 Barg (500 psig)

b. Minimum pumping temperature 0°C (32°F)

c. Maximum pumping temperature 150°C (300°F)

d. Maximum rotational speed 3,600 rpm

Comment: For services within the capabilities of ANSI/ASME pumps, use PIP RESP73V.

Pumps covered by this Practice are classified as diffuser-and-volute, separate discharge cantilevered, and vertical can.

Vertical in-line and submersible pumps have special design characteristics and are not included in the scope of this Practice.

Fire water pumps are covered by NFPA 20 and are not covered by this Practice.

RESP004

Liquid Ring Vacuum Pumps and Compressors Specification

Abstract ↓

This Practice provides the requirements for liquid ring vacuum (LRV) pumps and compressors, drivers, and associated equipment.

This Practice describes the standard arrangement for liquid ring vacuum pumps and compressors and systems employing liquid ring machines. This Practice provides a framework for specifying a skid- mounted liquid ring machines system, “package,” for systems with drivers less than or equal to 150 kW (200 hp). This Practice can be applied to simple once-through arrangements, partial recirculation, and total recirculation systems.

Comment: This Practice can be used in conjunction with API 681.

A liquid ring machine data sheet, RESP004-DM/D, is included with this Practice. This data sheet may be used to communicate purchaser requirements; however, supplemental information may be necessary to fully define process requirements.

Vendor websites provide excellent visualizations of how LRV machines operate.
