Practices by Discipline

This Practice provides requirements for suppliers providing hygienic stainless steel check valves included in PIP Piping Line Class Material Specifications. For the purposes of this practice, “Hygienic,” “Process,” or “Hygienic Process” refers to all Hygienic Processes for Food/Beverage/Consumer & Current Good Manufacturing Practices (CGMP) or other products requiring a clean design.

This Practice provides a system for engineers to identify abbreviated piping terms and acronyms used in PIP piping Practices. This Practice establishes the definitions and interpretations for all piping-related abbreviations and acronyms used in piping Practices. Abbreviations for technical societies, codes, standards, etc., are not included.

This Practice provides minimum requirements for qualifying welders in accordance with API 1104. Welder qualification tests are given to determine the ability of the welder to make sound welds using qualified weld procedures (WPS). For welder qualification requirements in accordance with ASME Section IX, see PIP PLSC0017.

This Practice provides fabrication and installation details and dimensional tolerances for the design of supports and other attachments for vessels, heat exchangers and solids products containers.

This Practice provides fabrication and installation details and dimensional tolerances for the design of supports and other attachments for vessels, heat exchangers and solids products containers. Dimensions are conversion of the PIP VESV1100 dimensions using the conversion guidelines of ASME Section VIII, Appendix GG.

This Practice describes minimum requirements for design, performance, inspection, testing, and documentation of automatic delayed transfer systems (ATS) for two-source secondary selective substations, typically known as Main-Tie-Main transfer scheme. ATS provides automatic restoration of bus voltage upon loss of one of the sources. This Practice also covers remote monitoring and control requirements. This Practice does not cover fast bus transfer or delayed in-phase transfer systems.

This Practice provides the arrangement of PIP valve tag number designations for manually operated valves in hygienic service and requirements for each field within a designation. Designation requirements are provided for both PIP-developed and purchaser-developed valve tag numbers.

This Practice provides minimum requirements for design, fabrication, inspection, testing, shipment, and documentation, for metal-enclosed power factor correction capacitors, from 2.4 kV to 35 kV, containing lightning/surge arrestor, transient inrush or tuning reactors, vacuum circuit breaker, capacitor, capacitor protection, insulated buses, and control for indoor/outdoor installation in unclassified areas. This Practice covers fixed, manual, and automatic switched capacitor banks.

This Practice provides requirements for suppliers providing carbon steel check valves included in PIP Pipeline Systems Material Specifications (PMSs).

This Practice provides requirements for suppliers providing carbon steel plug valves included in PIP Pipeline Systems Material Specifications (PMSs).

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

This Practice provides requirements for suppliers providing hygienic bronze check valves included in PIP Piping Line Class Material Specifications.

The purpose of this guideline is to describe when and why potholing is utilized for construction and design activities, potholing methods, advantages and disadvantages of the methods included, and one-call resources. Potholing may be utilized, as required and described herein, to prevent excavation damage to underground utilities and to avoid unknown foreign utilities.
