Purchasing Requirements for Control Valves
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.

Control Valves Selection Criteria
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.
Technical Revision
Acoustic Insulation Systems Specification
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.
Technical Revision
Hot Insulation Installation Details
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.

Guidelines for Minimum and Maximum Flow Rates for Centrifugal Pumps (Universally 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.
Technical Revision
Pipeline Material Specifications (PMS) Index
​This Practice describes the basic characteristics of each PIP Pipeline Systems Piping Material Specification (PMS). Each specification listed is described by pressure class, primary material, design factor, corrosion allowance, service type, and joint construction.
New Practice
Pipe Bending Guideline
This Practice provides guidance for evaluation, selection, and specification of pipe bends for on-shore metallic pipelines designed and constructed to ASME B31.8 Gas Transmission and Distribution Piping Systems and ASME B31.4 Pipeline Transportation Systems for Liquids and Slurries. This Practice covers the following types of bends:
a. Manufactured fittings
b. Induction (hot) bends formed off-site
c. Cold bends formed on-site
This Practice provides guidance for evaluation of which bend type to select by providing pros and cons based on specific site rights-of-way, pipe size and wall thickness, shipping considerations, pipe ovality, pigging requirements, etc. Additional, more explanatory references recommendations are also provided.
New Practice
Pig Trap Design Guideline
The purpose of this document is to provide guidance for the design and installation, maintenance, and operation of in-service pipeline pigging facilities. A pigging facility permits the operator to run pipeline pigs for corrosion control, in-line inspection, and flow assurance programs.
This engineering practice covers the design and installation of in-service pipeline pigging facilities for all new and existing pipelines. If there are conflicts between this specification, Owner's requirements, Industry standards and regulatory requirement, the most stringent requirements shall apply.
This practice does not apply to temporary construction launchers/receivers or launchers/receivers for offshore use.
The installation of "temporary" pig traps shall be performed under the control of a MOC process that includes operations, engineering and safety design reviews.
New Practice
Electric Motor Mechanical Maintenance – Lubrication
This Practice covers the basic requirements for the lubrication of antifriction and hydrodynamic bearings used in electric motors. These requirements apply to induction, synchronous, and DC motors.
Excluded from this Practice:
- On site vibration analysis
- On site mechanical equipment alignment
- Repair of the motor, e.g. bearing replacement, rotor repair, stator repair, etc. (PIP ELTFT04 addresses motor repair.)
New Practice
Electric Motor Repair
​This Practice is an overlay to the IEEE document IEEE Std. 1068-2015, IEEE Standard for the Repair and Rewinding of AC Electric Motors in Petroleum, Chemical, and Process Industries. The intent is to use IEEE 1068-2015, with the exception and clarification as given in below, along with PIP ELTFT04-D and ELTFT04-T to define the requirements for repair, modification, and testing of electric motors.
New Practice
Reliability Indicators for Rotating Machinery (Universally Applicable)
This Practice provides standardized reliability terminology and a basis for measurement and data gathering for benchmarking the reliability of rotating machinery. This Practice describes reliability terms and definitions that can be applied to economic performance data generation. This Practice describes reliability data gathering techniques. This Practice provides basic steps to implementing reliability indicators in process industry facilities. This Practice describes levels of data gathering and analysis that may be used to provide the appropriate amount of reliability information.
Technical Revision
Instrumentation Electrical Installation Details
​This Practice provides installation details for instrument field junction boxes and instrument conduit and cable connections. This Practice describes the minimum requirements for instrument field junction box installation and wiring. This Practice provides details for installing various arrangements of instrument conduit and cable connections.
