This Practice describes the requirements for excavation, placement, inspection, and management of materials during the site preparation, excavation, and backfill phase of a construction project.

This Practice supplements ACI 351.5-15, Specification for Installation of Epoxy Grout between Foundations and Equipment Bases. Together, this Practice and ACI 351.5-15 provide requirements for supplying, testing and installing epoxy grout materials. The requirements of ACI 351.5-15, as modified and supplemented by this Practice, are adopted by this Practice for supplying, testing and installing epoxy grout materials.

This Practice supplements ACI 351.5M-15, Specification for Installation of Epoxy Grout between Foundations and Equipment Bases (Metric). Together, this Practice and ACI 351.5M-15 provide requirements for supplying, testing and installing epoxy grout materials. The requirements of ACI 351.5M-15, as modified and supplemented by this Practice, are adopted by this Practice for supplying, testing and installing epoxy grout materials.

This Practice supplements ACI 351.4-14, Specification for Installation of Cementitious Grouting between Foundations and Equipment Bases. Together, this Practice and ACI 351.4-14 provide requirements for supplying, testing and installing nonshrink cementitious grout materials. This Practice is applicable for nonshrink cementitious grout materials installed between foundations and equipment and machinery bases as well as nonshrink cementitious grout materials installed between foundations and structural steel column bases. The requirements of ACI 351.4-14, as modified and supplemented by this Practice, are adopted by this Practice for supplying, testing and installing nonshrink cementitious grout materials.

This Practice provides requirements for suppliers providing stainless steel check valves included in PIP Piping Material Specifications (PMSs).

This Practice provides requirements for designing instrument air systems that supply pneumatically actuated instruments and valves. This Practice describes the requirements for air quality, capacity, sizing, and testing of instrument air systems.

This Practice provides guidelines for designing instrument air systems that supply pneumatically actuated instruments and valves. This Practice provides design guidelines for air quality, capacity, sizing, and testing of instrument air systems.

This Practice provides requirements for suppliers providing carbon steel butterfly valves included in PIP Piping Material Specifications (PMSs).

This Practice provides the detailed purchase descriptions for carbon steel ball valve tag numbers included in PIP Piping Material Specifications and used along with PIP PNSM0110 for the procurement of valves. This Practice also provides a cross reference for carbon steel ball valve tag numbers to applicable PIP Piping Material Specifications (PMSs).

Scope The purpose of this Practice is to specify the requirements for design and manufacture of horizontal end suction centrifugal pumps. The requirements in this Practice are modifications, additions, and/or deletions (exceptions) to the requirements in ASME B73.1 - 2020. The section/paragraph numbers and the associated headings used in this Practice correspond to the ones used in ASME B73.1. Since this Practice does not take exception to all the requirements in ASME B73.1, the section/paragraph numbers in this Practice may not be sequential. Data sheets PIP RESP73 D and PIP RESP73-DM, appended, may be used to select options for ordering the pumps specified in this Practice. This practice is intended for chemical and hydrocarbon services and does not cover pumps sealed with packing. For general water services that fall out of the limitations of this practice use PIP RESP003H.

This Practice describes the minimum requirements for the procurement of metallic pipe fittings and flanges.

Electrical systems will experience electrical events in the form of voltage dips and outages. Depending on the magnitude and duration of these electrical events, electric motors can drop offline. The unexpected loss of an electric motor in a production unit can cause personnel safety issues, environmental issues, and loss profit opportunities (LPO). This Practice provides information which can be used to develop the basic premises on which to implement a voltage dip impact mitigation program to help overcome the adverse effects of production units dropping offline. The voltage dip impact mitigation program addresses the application of both under-voltage ride-through and under-voltage restart capabilities which should be added to the controls of electrical motors.
