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
Guidelines for Selection of Rotating Equipment Bearing Lubrication Methods (Universally Applicable)
This Practice provides guidelines for selecting lubrication methods for bearings in rotating equipment applications.
This Practice describes the product-lubrication, grease, wet sump, dry sump, and pressure-fed lubrication methods for lubricating bearings, and provides guidance for applying the methods to various applications.
Technical Revision
Guideline for Adoption and Implementation of PIP Practices
This Practice provides guidance for developing a system of company standards based on the adoption of PIP Practices. This Practice provides information and recommendations regarding the benefits of adopting PIP, how PIP is positioned in a standards system, and strategies for adopting PIP based on corporate capabilities.

Document Mark-up Guidelines (Universally Applicable)
This Practice provides guidelines for identifying changes or making comments to all types of engineering drawings, documents, lists, etc, specifically where the changes or comments are made by one or multiple people and incorporated into the native or master document by another person.
This Practice covers all revisions/modifications of documents, including documents before and after construction.
This Practice does not apply to mark-ups made before the adoption of this Practice.
This Practice does not address how to implement a Management of Change (MOC) work process; it does address how to communicate mark-ups consistently.
This Practice should be applied to any engineering document, paper or electronic, and is not vendor, hardware, or software specific.
Although this Practice provides general guidelines for the markup of engineering documents, 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. (This guideline is meant just a starting point.)
Example document markups in the Appendix 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.
New Practice
Underground Gravity Sewers Specification
This Practice describes requirements for materials, installation, and testing of underground gravity sewers. This Practice includes requirements for pipe, inlet structures, manholes, and appurtenances for sanitary, storm, and industrial process sewers. This Practice does not include requirements for pressurized pipe, double-contained pipe, or emission-controlled industrial process sewers in environmental applications.

Level Transmitter Installation Details
This Practice contains installation details for differential pressure transmitters in liquid level service and includes details for electric or steam tracing of these installations. These details describe the base instrument installations. The bill of material provided with each detail is generic and is complementary to PIP PCSIP001- Instrument Piping and Tubing Systems Specifications.
Reaffirmation with Editorial Revision
Atmospheric Storage Tank Specification (Supplement to API Standard 650)
This Practice supplements API 650, Welded Steel Tanks for Oil Storage. Together, this Practice and API 650 provide requirements for the construction of atmospheric storage tanks.
This Practice and API 650 describe minimum construction requirements for the materials, design, fabrication, erection, examination, and testing of aboveground, non-refrigerated storage tanks. This Practice describes additions and modifications made to API 650. In addition, this Practice describes decisions made regarding options offered by API 650. This Practice supplements, but does not supersede, API 650 and any applicable jurisdictional requirements.
This Practice covers storage tanks that have design internal pressures of 17.2 kPa (2.5 psig) or less (see API 650, Annex F) and design temperatures less than 260°C (500°F) (see API 650, Annex M).
This Practice presumes the use of the API 650 Data Sheet to cover the requirements in API 650, and the Data Sheet, as a supplement, to define the additional requirements of this Practice.
Technical Revision
Design and Fabrication of Medium-Voltage Gas-Insulated Switchgear up to 52kV
This Practice covers the minimum requirements for design, fabrication, inspection, testing, shipment, and documentation for gas insulated switchgear containing gas-insulated buses, power circuit breakers, control, instrumentation, and metering for installation in unclassified areas. This Practice also covers remote monitoring and control requirements.
New Practice
Design and Fabrication of Medium-Voltage Gas Insulated Switchgear up to 52kV (IEC)
This Practice covers the minimum requirements for design, fabrication, inspection, testing, shipment, and documentation for gas insulated switchgear containing gas-insulated buses, power circuit breakers, control, instrumentation, and metering for installation in unclassified areas. This Practice also covers remote monitoring and control requirements.
New Practice
Liquid Containment Pits Design Guide
This Practice provides design considerations to engineers designing liquid containment pits, holding ponds, and basins. It includes civil, geotechnical, and hydrological engineering aspects, specifically addressing pits lined with geomembranes.
New Practice
Instrumentation Electrical Design Criteria
This Practice provides requirements for electrical design for instrumentation.
This Practice describes the requirements for equipment selection, system design, and installation of electrical supply and wiring to support instrumentation for process measurement and control systems. Both US and international standards are referenced in this document. The user should select the appropriate standards according to the geographical location and regulatory agencies.
Technical Revision
Instrument Piping and Tubing Systems Criteria
This Practice describes the general requirements for the design and installation of instrument air and process piping and tubing. Analyzers and analyzer sample systems are not covered by this Practice.
