This Practice provides general requirements for the design, materials, fabrication, examination, inspection, testing, certification, and pressure relief of three classes of small pressure vessels and heat exchangers as defined by size and Maximum Allowable Working Pressure (MAWP) in Table 1a or 1b of this Practice. This Practice is applicable to a. The standard, pre-designed pressure vessels and heat exchangers supplied as part of pre-engineered package units (e.g., refrigeration and air-compressor systems) b. “Off-the-shelf” vessels and exchangers c. Vessels (e.g., filters) or exchangers built from the manufacturer’s standard parts For purposes of this Practice, the term “vessel” includes heat exchangers. This Practice is not intended for the following a. Vessel in “Lethal Service” as defined in Section VIII, Division 1 of the ASME Boiler and Pressure Vessel Code (Code) b. Vessels for which design wall thickness is governed by loadings from wind pressure or earthquake forces

This Practice provides guidelines to establish a common framework and understanding for owners and contractors before execution of any project engineering effort. The Practice will act as a guide and checklist for discipline-specific engineering teams on requirements including roles and responsibilities.

This Practice provides requirements for suppliers providing hygienic stainless steel butterfly valves included in PIP Piping Line Class Material Specifications.

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

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

This Practice provides requirements for quality control and quality assurance for the installation of ceramic fiber refractory. Inspection methods include documentation review, in-progress installation inspection, and final inspection of the completed lining.

This Practice provides guidelines for aboveground storage of liquid products in tanks at design pressures from atmospheric to 15 psig (103 kPa). This Practice also provides guidance for avoiding recurring problems and outlines preferred practices where appropriate. Although this Practice is intended primarily for carbon steel tanks, most of the guidelines are applicable regardless of the material of construction.

This Practice provides guidance to users for the inspection and maintenance of thermal insulation systems.

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

This Practice provides the requirements for design and fabrication of vented, flooded-cell lead-acid batteries and accessories. It further describes the design, inspection, testing, shipment, and documentation for these type batteries for application in electrical stations or uninterruptible power supplies (UPS) in indoor, nonclassified areas.

This Practice provides design criteria for fixed gas detectors installed in process areas to detect the presence of combustible, oxygen, or toxic gases. This Practice addresses combustible, oxygen, and toxic gas detectors permanently installed for ambient air monitoring (e.g., leak detection, oxygen depletion). The technologies included are catalytic bead, infrared, and electrochemical. 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.

This Practice describes the arrangement of the PIP Pipeline Systems Material Specification (PLMS) designations and the requirements for each field within a designation. Designation requirements are provided for both PIP-developed and owner-developed pipeline systems material specifications. A one-page summary of the PIP PLMS specified in this Practice is provided in Appendix D.

This Practice provides the minimum requirements for design, procurement, and construction for clean rooms. A clean room is a room within which the number concentration of airborne particles is controlled and classified, and which is designed, constructed, and operated in a manner to control the introduction, generation, and retention of particles inside the room. Clean rooms may be procured as modular, pre-fabricated units, or constructed on site from materials selected to minimize generation of particles and to resist microbial growth over time. This Practice provides an overview of design considerations to complement the use of its associated data sheet.

This Practice covers minimum requirements for the maintenance of power cables. It is applicable for both low voltage (≤ 1000 volts) and medium voltage (> 1000 volts to < 100 kV) systems. It is intended for use on power cables of extruded dielectric insulation or laminated dielectric insulation. This Practice is intended for maintaining power cables used in distribution, transmission, etc. type applications. The maintenance of electric motor conductors is covered in PIP ELTFT02; however, this Practice may be used for the maintenance of motor conductors if approved by the owner’s AHJ. While this Practice is intended for the maintenance of power cables, the testing and assessment procedures described below can be applied to installation and acceptance testing. The test voltages and applied times will vary between the maintenance test and the other tests. Refer to the IEEE and NETA documents found in the Reference section below for these differences. This Practice does not cover testing of bare overhead conductors.

This Practice provides guidelines for selection, design, layout and installation of steam traps.
