Standard Description and Comparison of Centrifugal Pump in Petrochemical Industry

In the field of petroleum and chemical industry, the most widely used international standards for centrifugal pumps are API610, ISO5199 and ANSIB73.1M/B73.2M, while the domestic standards are GB3215 and GB5656/T. These standards are described below.

1.1 API is the abbreviation of the American Petroleum Institute. The purpose of API610 standard is to provide a procurement specification for the manufacture and procurement of centrifugal pumps.

API610 (seventh edition) is proposed for centrifugal pumps used in oil refineries, and its standard name is Central Pumps for General Refinery Services. But in fact, it is not only oil refineries that use API610 standard, but also oil, chemical, natural gas and other fields often use API610 standard. In order to meet this need, API610 (the eighth edition) issued in 1995 was renamed as "Centrifugal Pumps for Petroleum, Heavy Chemical, and Gas Industry Services", and its content was significantly changed from the previous edition.

API610 has attracted much attention to energy conservation. API610 requires manufacturers and users to actively seek innovative energy-saving methods in the manufacturing, selection and operation of equipment. If this energy-saving method can improve efficiency and reduce the total cost of the service life without sacrificing safety or reliability, it should be encouraged. In addition, the evaluation criteria for selecting equipment shall be based on the total cost of the equipment during its service life, rather than the purchase cost of the equipment.

At present, in the field of petroleum and chemical industry, API610 is the most frequently used international standard for centrifugal pumps. The International Organization for Standardization has also adopted the API610 standard, which is attached to the standard number ISO/CD13709.

1.2 ISO5199

ISO is the abbreviation of the International Organization for Standardization. ISO5199 Technical Specification for Centrifugal Pumps, Class II, is mainly based on German DIN standards. Its overall dimension and performance comply with ISO2858 standard; The base complies with ISO3661; The cavity size for mechanical seal or soft packing shall comply with ISO3069; Performance test level B conforms to ISO3555, and level C conforms to ISO2548.

China's GB5656, Germany's DINISO5199 and France's NFISO5199 are equivalent to ISO5199; British BS6836 is equivalent to ISO5199. China GB5662, Germany DIN24256, Britain BS5257, France NFE44121, equivalent or equivalent to ISO2858.

1.3 ASMEB73.1M/B73.2M

ASME is the abbreviation of the American Society of Mechanical Engineers. 0b2l5L0 {9U $DASMEB73.1M-1991 Specification for Horizontal End Suction Central Pumps for Chemical Process and ASMEB73.2M-1991 Specification for VerticalIn-line Central Pumps for Chemical Process are American national standards, which are jointly prepared by pump manufacturers and chemical manufacturers. Pumps that meet these two standards are called ANSI pumps.
