Overview of API 610 10th edition
API stands for American Petroleum Institute, which is the largest trade association for the oil and gas industry in the United States. It develops standards, codes, specifications, recommended practices, guidelines, and technical reports for various aspects of the industry, such as exploration, production, refining, transportation, storage, distribution, safety, environmental protection, quality management, etc.
API 610 is one of the most widely used standards in the industry. It covers centrifugal pumps for petroleum, petrochemical, and natural gas industries. Centrifugal pumps are devices that use a rotating impeller to increase the pressure and flow rate of a fluid. They are commonly used in oil and gas applications such as pumping crude oil from wells, transferring refined products through pipelines or terminals, injecting water or chemicals into reservoirs or wells, etc.
The first edition of API 610 was published in 1955. Since then, it has been revised and updated several times to reflect the latest technological developments, industry needs, customer expectations, regulatory requirements, etc. The current version is the 10th edition, which was published in October 2004. It is identical to ISO 13709:2003 (International Organization for Standardization), which means that it has been adopted by many countries around the world.
Scope and applicability of the standard
API 610 applies to centrifugal pumps that are used in petroleum refineries; petrochemical and chemical plants; gas processing plants; offshore, onshore, and synthetic crude oil production plants; pipeline installations; and other services that require pumps of similar design and construction. It does not apply to pumps that are designed for nuclear service, fire water service, cryogenic service, etc.
API 610 covers both single-stage and multistage pumps, as well as pumps that run in reverse as hydraulic power recovery turbines (HPRTs). It also covers different types of pumps, such as overhung pumps (OH), between-bearings pumps (BB), and vertically suspended pumps (VS). The standard provides detailed descriptions, classifications, and nomenclatures for each type of pump.
Key definitions and terminology
API 610 defines various terms and concepts that are essential for understanding the standard and its requirements. Some of the key definitions are:
Rated conditions: The set of conditions (such as flow rate, head, speed, power, etc.) at which the pump is designed to operate and which are specified by the purchaser.
Preferred operating region (POR): The range of flow rates within which the pump operates with acceptable efficiency, reliability, and vibration levels.
Allowable operating region (AOR): The range of flow rates within which the pump can operate without causing damage or excessive wear to the pump or its components.
Maximum allowable working pressure (MAWP): The maximum pressure that the pump pressure casing can withstand at a given temperature.
Minimum continuous stable flow (MCSF): The minimum flow rate at which the pump can operate without causing instability, cavitation, overheating, or excessive vibration.
Net positive suction head required (NPSHR): The minimum pressure that the liquid must have at the pump suction flange to prevent vaporization or cavitation of the liquid.
Net positive suction head available (NPSHA): The actual pressure that the liquid has at the pump suction flange minus the vapor pressure of the liquid.
Classification and selection of pump types
API 610 classifies centrifugal pumps into three main categories based on their configuration and support arrangement: overhung pumps (OH), between-bearings pumps (BB), and vertically suspended pumps (VS). Each category has several subtypes that differ in their design features, such as impeller type, number of stages, bearing type, shaft orientation, etc. The standard provides tables and diagrams that show the characteristics and applications of each pump type.
The selection of the appropriate pump type depends on various factors, such as the service conditions, performance requirements, installation space, maintenance accessibility, cost-effectiveness, etc. The standard provides guidelines and recommendations for selecting the best pump type for a given service. However, the final decision is up to the purchaser and the manufacturer based on their mutual agreement.
Technical requirements of API 610 10th edition
API 610 specifies the minimum technical requirements for centrifugal pumps in terms of design criteria and specifications, testing and inspection methods, documentation and data requirements, etc. These requirements are intended to ensure that the pumps meet the performance expectations, safety standards, quality assurance, reliability objectives, etc. of the industry. The standard also allows for deviations or exceptions from these requirements if they are agreed upon by the purchaser and the manufacturer.
Design criteria and specifications
The standard provides detailed design criteria and specifications for various aspects of centrifugal pumps, such as:
Pressure casing and nozzle loads
The pressure casing is the part of the pump that contains the liquid under pressure. It consists of several components, such as suction casing, discharge casing, diffuser casing, volute casing, etc. The pressure casing must be designed to withstand the internal pressure and external loads without exceeding the allowable stress limits or causing excessive deformation or leakage.
The nozzle loads are the forces and moments that are applied to the pump nozzles by the connected piping system. These loads can cause stress and strain on the pressure casing and affect its alignment and integrity. The standard specifies the maximum allowable nozzle loads for different types and sizes of pumps. It also requires that each nozzle be able to withstand these loads simultaneously.
Shaft sealing systems and seal chambers
The shaft sealing system is the device that prevents or minimizes leakage of liquid from the pump along the rotating shaft. It consists of several components, such as mechanical seals, seal rings, seal faces, seal glands, seal flushes, etc. The shaft sealing system must be designed to provide adequate sealing performance under various operating conditions without causing excessive heat generation, friction, wear, or leakage. The standard specifies the types and arrangements of mechanical seals that are suitable for different pump types and service conditions. It also specifies the dimensions and design features of seal chambers that accommodate the mechanical seals.
Bearings and lubrication systems
The bearings are the components that support the rotating shaft and reduce friction and wear between the shaft and the housing. They can be either antifriction bearings (such as ball or roller bearings) or plain bearings (such as sleeve or journal bearings). The standard specifies the types and ratings of bearings that are appropriate for different pump types and service conditions. It also specifies the minimum bearing life expectancy and the methods for calculating the bearing loads and life.
The lubrication system is the device that provides lubricant to the bearings and other moving parts of the pump. The lubricant can be either oil or grease, depending on the pump type and service conditions. The standard specifies the types and properties of lubricants that are compatible with different pump materials and operating temperatures. It also specifies the design criteria and specifications for lubrication systems, such as reservoirs, pumps, filters, coolers, heaters, piping, etc.
Baseplates and foundations
The baseplate is the structure that supports the pump and its driver (such as an electric motor or a steam turbine). It provides a rigid and level surface for mounting and aligning the pump and its driver. It also helps to dampen vibrations and noise from the pump operation. The standard specifies the materials, dimensions, and design features of baseplates for different pump types and service conditions. It also specifies the requirements for grouting, leveling, anchoring, and aligning the baseplates.
The foundation is the structure that supports the baseplate and transfers its load to the ground or floor. It provides a stable and secure base for the pump installation. The standard provides general guidelines for designing and constructing foundations for different pump types and service conditions. It also provides recommendations for preparing, curing, and testing concrete foundations.
Testing and inspection methods
The standard specifies the methods and procedures for testing and inspecting centrifugal pumps to verify their compliance with the standard requirements and specifications. These methods include:
Hydrostatic testing and performance testing
Hydrostatic testing is a method of applying internal pressure to the pump pressure casing to check its integrity and strength. It is performed before performance testing to ensure that there are no leaks or cracks in the casing. The standard specifies the test pressure, duration, procedure, acceptance criteria, and documentation for hydrostatic testing.
Performance testing is a method of measuring the flow rate, head, power, efficiency, NPSH required, vibration, noise, etc. of the pump under various operating conditions. It is performed to verify that the pump meets the rated performance characteristics specified by the purchaser. The standard specifies the test setup, procedure, instrumentation, accuracy, tolerances, corrections, acceptance criteria, and documentation for performance testing.
Vibration and noise limits
Vibration is a measure of the oscillatory motion of the pump components due to unbalanced forces or moments acting on them. Excessive vibration can cause damage or failure of the pump components or affect their performance or reliability. The standard specifies the maximum allowable vibration levels for different pump types and service conditions. It also specifies the methods for measuring, analyzing, reporting, and correcting vibration.
Noise is a measure of the sound pressure level generated by the pump operation due to fluid flow, mechanical motion, turbulence, cavitation, etc. Excessive noise can cause annoyance or discomfort to personnel or violate environmental regulations.
