This Practice provides the requirements for liquid ring vacuum pumps and compressors, drivers, and associated equipment. This Practice describes the standard arrangement for liquid ring vacuum pumps and compressors and systems employing liquid ring machines. This Practice provides a framework for specifying a skid mounted liquid ring machines system “package,” for systems with drivers less than or equal to 150 kW (200 hp). This Practice can be applied to simple once-through arrangements, partial recirculation, and total recirculation systems.Comment This Practice can be used in conjunction with API 681.A liquid ring machine data sheet, RESP004-DM/D, is included with this Practice. This data sheet may be used to communicate purchaser requirements; however, supplemental information may be necessary to fully define process requirements.Vendor websites provide excellent visualizations of how LRV machines operate.

​This Practice provides requirements for design and manufacture of horizontal centrifugal pumps of 150 kW (200 HP) or greater used for general water services. Comment General water services include condensate, cooling water, demineralized water, utility water, produced water, treated water, etc. This Practice covers pumps with service conditions within the following limits a. Maximum discharge pressure 35 Barg (500 psig) b. Minimum pumping temperature 0°C (32°F) c. Maximum pumping temperature 150°C (300°F) d. Maximum rotational speed 3,600 rpm Comment For services within the capabilities of ANSI/ASME pumps, use PIP RESP73H. Pump types covered by this Practice are broadly classified as overhung or between-bearings. The following pump types are not included in the scope of this Practice a. Close coupled (i.e., impeller mounted on the motor shaft) b. Two-stage overhung c. Double suction overhung Fire water pumps are covered by NFPA 20 and are not covered by this Practice.

​This Practice provides requirements for design and manufacture of vertical submerged motor centrifugal pumps of 150 kW (200 HP) or greater used for water services. Comment Water services include condensate, cooling water, demineralized water, utility water, produced water, treated water, etc. Comment General water services include condensate, cooling water, demineralized water, utility water, produced water, treated water, etc. This Practice describes manufacturing and performance requirements for vertical submerged motor centrifugal pumps and their accessories. This Practice covers pumps with service conditions within the following limits a. Maximum discharge pressure 35 Barg (500 psig) b. Minimum pumping temperature 0°C (32°F) c. Maximum pumping temperature 150°C (300°F) d. Maximum rotational speed 3,600 rpm Comment For services within the capabilities of ANSI/ASME pumps, use PIP RESP73S.

This Practice provides requirements for the design, materials, fabrication, examination, inspection, testing, certification (ASME stamp and Supplier’s Data Report), and pressure relief of aboveground fiberglass reinforced polyester, vinyl ester, and epoxy tanks and vessels having internal or external pressure from full vacuum up to the limits of Code Section X. This Practice covers shop- and field-fabricated equipment, thermoplastic-lined equipment, and dual laminate equipment.This Practice does not cover the following equipment items that are excluded from both ASME RTP-1 and Code Section Xa. Portable or movable containersb. Hoods, ducts, and stacksc. Fans and blowersd. Vessel internals such as entrainment separators, chevron blades, packing support plates, and liquid distributor platese. Pipe or pipingf. Fully buried underground closed vesselsThis Practice does not cover the following equipment items that are excluded from Code Section Xa. Vessels having an inside diameter (ID), width, height, or cross-section diagonal of 6 inches (150 mm) or less, with no limitation on length or pressure. The 6-inch (150 mm) dimension excludes (150 mm) the thickness of any corrosion liner.b. Vessels containing lethal substances as designated by the owner in accordance with Code Section X Paragraph RG-113.This Practice does not cover the following equipment items that are excluded from ASME RTP-1a. Vessels constructed of furan, epoxy, or phenolic resinsb. Vessels with non-glass structural reinforcementsc. Vessels having metallic liners

This Practice provides data forms for specifying requirements for horizontal, vertical, and vertical submerged motor centrifugal pumps of 150 kW (200 HP) or greater for water service.This Practice contains two data forms for providing documentation, inspection, and testing requirements for horizontal, vertical, and vertical submerged motor centrifugal pumps of 150 kW(200 HP) or greater for water service. This Practice is to be used in conjunction with any of the following Practices– PIP RESP003H - Specification for High Power Horizontal Centrifugal Pumps for Water Service– PIP RESP003S - Specification for High Power Vertical Submerged Motor Centrifugal Pumps for Water Service– PIP RESP003V - Specification for High Power Vertical Centrifugal Pumps for Water Service

​This Practice provides requirements for quality control and quality assurance for the installation of monolithic refractory lining materials. The test and inspection methods include installer prequalification, production sample testing, in-progress installation inspection, and final inspection of the completed lining.

This Practice provides requirements and details for fabrication of angle guards for walking andworking surfaces and angle guards with pipe handrails for standard stairs used for access andegress in industrial facilities.

​This Practice provides fabrication/installation details for piping supports used in a hygienic environment requiring clean or cGMP design. This Practice describes the minimum requirements to fabricate or install hygienic piping supports. These are different than traditional piping supports in that they avoid flat surfaces, crevices, and points of harborage.

​This Practice provides the detailed purchase descriptions for plastic and plastic lined ball valve tag numbers included in PIP Piping Material Specifications and used along with PIP PNSM0110 for the procurement of valves. This Practice also provides a cross reference for plastic and plastic lined ball valve tag numbers to applicable PIP Piping Material Specifications.
