This Practice provides the requirements for junction boxes used for instrumentation signals, thermocouples, and resistance temperature detectors (RTDs).This Practice describes the requirements for instrumentation junction boxes and is only for junction boxes installed in general purpose or Division II area classifications with wiring and terminals in accordance with the National Electric Code (NEC). Junction boxes in accordance with this Practice are not to be used for electronics or other active elements without additional consideration.

​This Practice provides fabrication details and describes the minimum requirement for fabricating galvanized pipe supports for instruments for various mounting arrangements.

This Practice provides installation details and describes the minimum requirements for attaching instrument pipe supports to various support structures.

This Practice contains installation details for adding single or dual purge supply systems thatsupply purge fluid through tubing, transmitter body, or orifice unions to a pressure or differentialpressure transmitter. Instrument accessory details are shown in PIP PCIGN300 – GeneralInstrument Accessory Details.

​This Practice contains accessory details that can be added to a pressure or differential pressure transmitter installation detail. Included are seal pot, blowdown, fill tee, rod out, coplanar transmitters, and steam trace supply condensate return details. Instrument purge details are shown in PIP PCIGN200 – General Instrument Purge Details.

​This Practice describes the requirements for the design, fabrication, assembly, inspection and testing, and shipment of custom steel instrument control panels. There are occasional cases where other material may be required. This does not cover the fabrication using alternate materials.

This Practice provides installation details and describes the minimum requirements for installingorifice plates in gas, liquid, steam, or condensing vapors service.

​This Practice describes guidelines for selecting appropriate types of centrifugal and positive displacement pumps for specific process services. This Practice does not cover every pump application or every type of pumping device available.

Pairs or triads may include individual shields and/or an overall shield.

This Practice provides designers and engineers with requirements to help reduce the Total Cost ofOwnership (TCO) of rotating machinery by determining allowable piping loads and piping loadapplications.Comment: Owner experience has shown that designing machinery piping to the maximumpublished allowable loads results in low mean time between repair (MTBR) andhigher than acceptable maintenance costs.This Practice limits the application of the entire maximum allowable nozzle load during theequipment installation design, allowing some reserve margin to maximize the possibility of thefinal installation actually remaining within the allowable loading.This Practice drives the stated, published and calculated allowable nozzle loads to become moreperformance based, tied more closely to actual effects on the MTBR and TCO for the machineryin order to:a. Promote the highest reliability for vital or sensitive machinery and the determination ofthose allowable loads that will allow the achievement of that reliabilityb. Allow spared (essential) machinery to be more heavily loaded, and encouragemanufacturers to either furnish allowable load data or be in accordance with a publishedstandardc. Encourage machinery manufacturers to generate more meaningful reliability-basedallowable nozzle load recommendationsd. Encourage standards organizations to look at the basis for their allowable loadvalues/calculation methods and verify the effects on the demonstrated MTBR and TotalCost of Ownership (TCO)This Practice describes the requirements for calculating allowable piping loads and theapplication of those loads for rotating machinery including pumps and compressors (centrifugal,reciprocating and rotary screw), steam and gas turbines, and liquid ring compressors. Also, thisPractice may be used on fans and blowers after consultation with the manufacturer.This Practice describes the requirements for allowable nozzle loads for vital or sensitivemachinery and for essential (spared) machinery.This Practice also outlines the requirements for minimizing loads imposed on equipment by thepiping systems.
