Pipeline pump models and specifications:What are the main models and specifications of pipeline pumps according to API 610?
Q: What are the main models and specifications of pipeline pumps according to API 610?
A: API 610 defines pipeline pump models primarily as horizontal centrifugal pumps in configurations such as OH2 (between-bearings) and BB2 (between-bearings, single-stage). Specifications include flow rates from 10 to over 10,000 m³/h, heads up to 3,000 m, and operating temperatures from -80°C to 450°C. Key parameters cover pressure ratings up to 150 bar, casing designs (radially split or axially split), and impeller types. API 610 also specifies material classes (e.g., S-6, C-6) and vibration limits. These standards ensure pumps meet refinery and pipeline service requirements for reliability, efficiency, and safety.
Q: What are the key specification parameters for selecting a pipeline pump?
A: Key specification parameters for pipeline pump selection include flow rate (capacity), total head, operating pressure and temperature, fluid properties (viscosity, density, corrosiveness), and NPSH required. According to the Hydraulic Institute Standards and API 610, engineers must also consider pump speed, efficiency, power consumption, and motor sizing. Additionally, specifications cover flange ratings (ANSI/ASME B16.5), seal types (mechanical seals per API 682), and bearing life (minimum 25,000 hours). These parameters ensure the pump integrates with pipeline systems, meets safety codes, and operates efficiently under specified conditions.
Q: How do ISO 13709 and API 610 differ in specifying pipeline pump models?
A: ISO 13709 and API 610 are technically equivalent for centrifugal pumps used in petroleum, petrochemical, and gas industries, but they differ in documentation and regional adoption. ISO 13709 provides an international framework, while API 610 is widely used in North America. Both specify pump models (OH, BB, VS types), performance ranges, materials, and testing. However, API 610 includes more detailed requirements for vibration, nozzle loads, and auxiliary piping. ISO 13709 may reference other ISO standards for flanges and testing. Users should consult the latest editions (API 610 12th Ed., ISO 13709:2009) for precise model and specification alignment.
Q: What are the typical specifications for a mainline pipeline pump in crude oil service?
A: Typical specifications for crude oil mainline pumps, based on API 610 and industry practices, include: model BB2 or BB3 (multistage), flow rates 1,000–10,000 m³/h, heads 200–2,000 m, and operating pressures up to 100 bar. Materials often use carbon steel or low-alloy steel for casings, with stainless steel impellers for corrosion resistance. Seals are dual pressurized per API 682. Drivers are typically variable-speed electric motors or gas turbines. Efficiency targets exceed 80%. These pumps must also comply with NFPA 30 for flammable fluids and API 676 for rotary pumps, though centrifugal types dominate mainline service.
Q: What are the model designations for vertical pipeline pumps and their specifications?
A: Vertical pipeline pumps are designated as VS (vertical suspended) types in API 610, including VS1 (wet pit, single casing), VS2 (wet pit, double casing), VS4 (line shaft), and VS6 (cantilever). Specifications typically cover flow rates 5–5,000 m³/h, heads up to 500 m, and temperatures -50°C to 400°C. They are used where floor space is limited or suction lift is required. Key specs include NPSH, setting depth, column pipe diameter, and discharge flange orientation. API 610 and HI standards govern design, testing, and vibration limits. These models are common in sump, cooling water, and pipeline booster services.

Common scenarios of "Pipeline pump models and specifications"
【采购经理】 你好，我们最近有个输油管道项目，需要采购一批管道泵。你能先介绍一下你们有哪些型号吗？
【销售工程师】 您好！我们主要生产卧式管道离心泵和立式管道泵两大类。常见型号有ISG、IRG、IHG、YG等系列。您能说说具体的工况参数吗？比如流量、扬程、介质温度？
【采购经理】 介质是柴油，常温，流量大概每小时100立方米，扬程需要50米左右。管道口径DN100。
【销售工程师】 根据您的要求，推荐IHG100-160型号，流量100m³/h，扬程50m，配15kW电机，进出口径100mm。这个型号专为输送清水或类似柴油的液体设计。
【采购经理】 IHG和ISG有什么区别？为什么推荐IHG而不是ISG？
【销售工程师】 ISG是普通管道离心泵，适用于清水；IHG是化工管道泵，过流部件采用耐腐蚀材质，更适合输送油品和轻微腐蚀性液体。柴油虽然腐蚀性不强，但IHG密封性更好，能有效防止泄漏。
【采购经理】 明白了。那这个型号的泵体材质是什么？密封形式呢？
【销售工程师】 泵体为铸铁，叶轮为不锈钢304。密封采用机械密封，材质为碳化硅对石墨，耐磨损且密封可靠。如果介质要求更高，可以选不锈钢泵体。
【采购经理】 机械密封的寿命大概多久？维护更换方便吗？
【销售工程师】 在清洁介质下，机械密封寿命通常8000小时以上。更换需要拆泵盖，一般维修人员30分钟内可以完成。我们提供备用密封件。
【采购经理】 电机防护等级和绝缘等级是多少？电源是380V/50Hz。
【销售工程师】 标配电机为IP55防护等级，F级绝缘，适合户外使用。380V/50Hz三相电源，15kW电机额定电流约30A。
【采购经理】 泵的进出口方向可以调整吗？我们现场管路布置可能需要进出口垂直或水平。
【销售工程师】 IHG系列泵的进出口方向在出厂时固定，但可以通过旋转泵体来改变角度，通常每90度一个档位，共四个方向可选。订货时请注明所需方向。
【采购经理】 好的。那安装时对基础有什么要求？需要减震吗？
【销售工程师】 建议安装在混凝土基础上，基础重量约为泵组重量的3倍。如果对噪音有要求，可以加装减震垫或采用弹性支座。我们可提供安装尺寸图。
【采购经理】 价格大概多少？如果采购5台，交货期多久？
【销售工程师】 IHG100-160单台价格约8500元，5台总价42500元，含税不含运费。交货期常规为15个工作日，如有现货可7天内发货。
【采购经理】 能提供性能曲线和详细选型报告吗？我们需要做技术评审。
【销售工程师】 当然可以。我会把IHG100-160的性能曲线、外形尺寸图、选型计算书和材质报告一起发给您。请提供邮箱，我今天内发送。
【采购经理】 好的，我的邮箱是purchase@example.com。另外，质保期是多久？
【销售工程师】 质保期为发货后12个月或运行2000小时，以先到为准。质保期内非人为损坏免费维修或更换配件。期待与您合作！
