Guidelines for Minimum and Maximum Flow Rates for Centrifugal Pumps (Universally Applicable)
This Practice provides recommended minimum and maximum flow rates for conventional centrifugal pumps (i.e., pumps with mechanical seals) to achieve safe operation while optimizing operating costs. This Practice describes how to use hydraulic and mechanical criteria to determine a recommended safe operating flow range for centrifugal pumps. This Practice does not provide hard limits for a pump's flow range because of factors that cannot be precisely defined.
Technical Revision
Lightning and Static Protection Guideline
This Practice addresses lightning and static protection for facilities that process, manufacture, store, and handle flammable, non-flammable, combustible, and non-combustible products and materials. This practice will also address lightning and static protection of the electrical infrastructure used to support the manufacturing of these materials.

Pipeline Material Specifications (PMS) Index
This Practice describes the basic characteristics of each PIP Pipeline Systems Piping Material Specification (PMS). Each specification listed is described by pressure class, primary material, design factor, corrosion allowance, service type, and joint construction.
New Practice
Pipe Bending Guideline
This Practice provides guidance for evaluation, selection, and specification of pipe bends for on-shore metallic pipelines designed and constructed to ASME B31.8 Gas Transmission and Distribution Piping Systems and ASME B31.4 Pipeline Transportation Systems for Liquids and Slurries. This Practice covers the following types of bends:
a. Manufactured fittings
b. Induction (hot) bends formed off-site
c. Cold bends formed on-site
This Practice provides guidance for evaluation of which bend type to select by providing pros and cons based on specific site rights-of-way, pipe size and wall thickness, shipping considerations, pipe ovality, pigging requirements, etc. Additional, more explanatory references recommendations are also provided.
New Practice
Pig Trap Design Guideline
The purpose of this document is to provide guidance for the design and installation, maintenance, and operation of in-service pipeline pigging facilities. A pigging facility permits the operator to run pipeline pigs for corrosion control, in-line inspection, and flow assurance programs.
This engineering practice covers the design and installation of in-service pipeline pigging facilities for all new and existing pipelines. If there are conflicts between this specification, Owner's requirements, Industry standards and regulatory requirement, the most stringent requirements shall apply.
This practice does not apply to temporary construction launchers/receivers or launchers/receivers for offshore use.
The installation of "temporary" pig traps shall be performed under the control of a MOC process that includes operations, engineering and safety design reviews.
New Practice
Electric Motor Mechanical Maintenance – Lubrication
This Practice covers the basic requirements for the lubrication of antifriction and hydrodynamic bearings used in electric motors. These requirements apply to induction, synchronous, and DC motors.
Excluded from this Practice:
- On site vibration analysis
- On site mechanical equipment alignment
- Repair of the motor, e.g. bearing replacement, rotor repair, stator repair, etc. (PIP ELTFT04 addresses motor repair.)
New Practice
Electric Motor Repair
This Practice is an overlay to the IEEE document IEEE Std. 1068-2015, IEEE Standard for the Repair and Rewinding of AC Electric Motors in Petroleum, Chemical, and Process Industries. The intent is to use IEEE 1068-2015, with the exception and clarification as given in below, along with PIP ELTFT04-D and ELTFT04-T to define the requirements for repair, modification, and testing of electric motors.
New Practice
Switchgear Maintenance
This Practice covers minimum requirements for the maintenance of switchgear. While the maintenance procedures herein can be applied to all types of switchgear, manufacturer instructions should be reviewed for equipment specific maintenance requirements.
This Practice does not cover the calibration, settings, or programming of protective devices such as molded case circuit breakers, protective relays, etc.
New Practice
Reliability Indicators for Rotating Machinery (Universally Applicable)
This Practice provides standardized reliability terminology and a basis for measurement and data gathering for benchmarking the reliability of rotating machinery. This Practice describes reliability terms and definitions that can be applied to economic performance data generation. This Practice describes reliability data gathering techniques. This Practice provides basic steps to implementing reliability indicators in process industry facilities. This Practice describes levels of data gathering and analysis that may be used to provide the appropriate amount of reliability information.
Technical Revision

Weigh Systems Design Criteria
This Practice provides requirements for equipment selection and system design for weight measurement systems. This Practice specifies requirements for design and installation of static, continuous, and scale weigh systems. This Practice does not include criteria for mechanical weigh scales, hydraulic load cells, or pneumatic load cell technology.
Reaffirmation with Editorial Revision
Instrument Air Installation Details
This Practice provides installation details for various instrument air supply and instrument signal arrangements. This Practice describes the minimum requirements for installing instrument air supply components with various air-set and filter arrangements. This Practice provides details for various instrument signal arrangements.
Technical Revision
Fixed Gas Detection Guidelines
This Practice provides guidelines for the selection, design, and application of fixed gas monitoring detectors installed in process areas to detect the presence of combustible gases, oxygen, or toxic gases. This Practice addresses detectors permanently installed for ambient air monitoring (e.g., leak detection, oxygen depletion). The technologies included are catalytic bead, infrared, electrochemical, paramagnetic. 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.
Technical Revision
