Practices by Discipline

This Practice provides requirements for suppliers providing plastic and plastic-lined plug valves included in PIP Piping Material Specifications (PMSs).​

This Practice provides requirements for suppliers providing stainless steel valves (other than gate, globe, check, ball, butterfly, and plug valves) included in the PIP Piping Material Specifications (PMSs).

This document provides the detailed descriptions for the purchase of butterfly valves included in PIP Piping Material Specifications (PMSs).

This Practice provides requirements for suppliers providing other valves (other than gate, globe, check, ball, butterfly, and plug valves) included in the PIP Piping Material Specifications (PMSs).​

This Practice provides requirements for suppliers providing nickel and nickel alloy valves (other than gate, globe, check, ball, butterfly, and plug valves) included in the PIP Piping Material Specifications (PMSs).

This Practice describes the electrical requirements for design, manufacture, inspection, testing, and shipping of packaged equipment (also referred to as skid mounted equipment). Electrical systems for packaged equipment may include components such as electrical enclosures, motors, motor controllers, heaters and process heaters, relays, controls and control panels, control stations, pilot devices, indicating lights, transformers, wires, and conduits. This Practice does not address requirements for motor control centers, switchracks, substations, power control centers or remote instrument enclosures.

This Practice provides the procedures for making revisions and updates to existing Process Industry Practices (Practices). This Practice describes all types of revisions to existing Practices, including the handling and solicitation of comments, the revision cycle, the numbering, the formatting of revisions, and the balloting and approval process for revisions, as well as notification and distribution of revisions. A flow chart that summarizes the revision processes is shown in Appendix A.

This Practice provides minimum technical requirements for the process and mechanical design, materials, fabrication, inspection, and testing of electric immersion process heaters and associated controls, including thyristor control panels. This Practice applies to electric immersion process heaters which are inserted and flange mounted on tanks and vessels, installed in dedicated pressure vessels, and installed in pipe.

This Practice describes requirements for supplying, transporting, handling, installing, and testing driven load-bearing piles. Pile types covered in this Practice are as follows a. Steel pipe piles b. Concrete-filled thin shell piles c. Steel H-piles d. Step taper piles e. Prestressed/precast concrete piles f. Timber piles This Practice is not applicable for sheet piles.

This Practice provides guidance for the application of the PIP PLD00001, Pipeline Project Documentation Requirements. It establishes the process for selecting project deliverables required at project completion to support ongoing operations and maintenance of assets. Companies may adopt this Practice for internal use and utilize the Pipeline Project Deliverables list as needed.

This Practice provides guidelines for specifying gaskets used with circular flanges for pressurized equipment and piping. It describes guidelines for use of gaskets with the following types of flanges a. Standard flanges in accordance with ASME B16.1, B16.5, B16.42, or B16.47 b. Custom flanges designed in accordance with Code, Division 1 Appendix 2 or Division 2, Paragraph 4.16 or Part 5 This Practice applies to all of the following a. Common gasket styles contained between flat (planar) flange surfaces b. Double jacketed, spiral wound, grooved metal with covering layer, corrugated metal, and sheet gaskets c. Design conditions not greater than the standard flange rating or the manufacturer’s published gasket rating if more restrictive This Practice does not address the following a. Confined gaskets, i.e., gaskets contained in grooves (e.g., ring joint, tongue and groove, male-female, spiral wound without retaining rings, etc.) b. Self-actuated gaskets (e.g., “o”-rings) c. Proprietary gasket styles d. Other types of gaskets not specifically covered in this Practice e. Cyclic service as defined for vessels in accordance with ASME Section VIII, Division 2, Paragraph 5.5.2, Screening Criteria for Fatigue Analysis (cyclic service is defined as requiring a fatigue analysis) and for piping by ASME B31.3 Paragraph 300.2, Severe Cyclic Service definition. The guidelines in this Practice are intended to a. Improve process containment; b. Reduce risk of personnel exposure; c. Enhance blowout prevention; d. Improve bolted joint reliability; and e. Provide for gasket standardization Specific services, environments, or situations may require considerations that take precedence over the guidelines of this Practice.
