Practices by Discipline

Not applicable

This Practice describes the minimum requirements for gaskets specified in PIP Piping Material Specifications (PMSs). This specification does not cover the purchase of custom gaskets for size ranges or pressure ranges outside the limits of PIP PMSs.

This Practice provides the minimum requirements for construction and installation of electrical power and control systems material and equipment.

This Practice describes design criteria for precast concrete manholes or cable vaults used in conjunction with underground electrical ducts, and installation of cables in underground manholes. Proper design and installation of manholes is essential for safety and reliability of plant electrical services. Basic designs and installation requirements included in this Practice shall be reviewed by site engineering personnel for each new installation to ensure proper application.

This Practice and the purchaser’s PIP ELSAP04-D Data Sheet describe the minimum requirements for design, fabrication, inspection, testing, shipment, and documentation for a complete on-line, UPS system of either a pulse width modulated (PWM) or ferroresonant type. A PWM-type UPS system includes a rectifier/charger, inverter, static bypass switch, manual bypass switches, transformers, and accessories. A ferroresonant-type UPS system includes a rectifier/charger, inverter, constant voltage or ferroresonant transformer, static bypass switch, manual bypass switches, transformers, and accessories.

This Practice describes the minimum general requirements for the control valve body construction, actuator, auxiliaries (e.g., positioner, limit switches, etc.), testing, inspection, and documentation. This Practice provides requirements for the format for providing data for each individual control valve, the method to be used for valve sizing, and other design considerations. For Control Valves sizing and selection see PIP PCCCV001 and PIP PCECV001.This Practice does not include requirements for motor-operated valves, on-off valves intended for emergency isolation, and valves with hydraulic actuators. For On-Off Valves, see PIP PCCCV003, Remotely Actuated On-Off Valves Selection Criteria and PIP PCECV003, Guidelines for Application of Remotely Actuated On-Off Valves.

This Practice describes requirements for selection and sizing of pneumatically actuated control valves, including requirements for body, bonnet, trim, actuator, accessories, and noise considerations.This Practice does not cover requirements for motor-operated valves, on-off valves, on-off valves intended for emergency isolation, or valves with hydraulic actuators. For these types of on-off valve applications see PIP PCECV003, Guidelines for Application of Remotely Actuated On-Off Valves.

This Practice covers minimum requirements for the maintenance of induction motors. The aspects of electrical maintenance are described. While many of the maintenance aspects covered in this Practice can be applied to synchronous and DC motor maintenance, synchronous and DC motor maintenance is not part of this Practice.

This Practice describes the requirements for the design, application, and extent of acoustic insulation on piping and equipment operating at high and low temperatures. Systems requiring additional insulation specifications beyond PIP Practices, such as ISO 15665, shall be covered by purchaser's documentation.Listing of or reference to supporting documents within this Practice does not imply suitability for specific designs.Comment Use of this Practice for contractual purposes requires the purchaser to make specific choices and assemble additional supporting documents.

This Practice provides installation details for hot insulation systems. This Practice provides details for installing hot insulation systems on piping, valves, horizontal and vertical vessels, and heat exchangers.

​This Practice describes the general requirements for surface preparation, application, and inspection of protective coatings.

​Not applicable

This Practice provides recommended minimum and maximum flow rates for conventional centrifugal pumps (i.e., pumps with mechanical seals) to achieve safe operation while optimizing operating costs. This Practice describes how to use hydraulic and mechanical criteria to determine a recommended safe operating flow range for centrifugal pumps. This Practice does not provide hard limits for a pump's flow range because of factors that cannot be precisely defined.

​This Practice addresses lightning and static protection for facilities that process, manufacture, store, and handle flammable, non-flammable, combustible, and non-combustible products and materials. This practice will also address lightning and static protection of the electrical infrastructure used to support the manufacturing of these materials.
