Project Overview

Representative engineering execution for critical hydrocarbon process duty.

Industry

Oil & Gas / Refining

Continuous refinery process and hydrocarbon product transfer.

Equipment

API 610 Process Pump

Radial split single stage centrifugal process pump.

Application Type

Heavy-Duty Process Service

Full compliance with API 610 and API 682 standards.

Application Challenge

Industrial oil & gas process systems require continuous, uninterrupted pumping under elevated operating pressures and high fluid temperatures. Key operational challenges include:

  • Extreme demand for continuous uptime without unplanned shutdown.
  • Zero tolerance for uncontained fluid leakage in volatile environments.
  • Strict allowable nozzle load and piping vibration limits per API 610 standards.
  • Variable operating conditions demanding stable hydraulic characteristics.

Engineering Solution

Songlone Pump engineers implemented a heavy-duty API 610 centrifugal process pump tailored for severe petrochemical duty:

  • Heavy-Duty Casing: Centerline mounted radial split casing designed to minimize thermal expansion misalignment.
  • Hydraulic Precision: Enclosed precision-machined impeller delivering optimal hydraulic efficiency and low NPSHr margin.
  • API 682 Sealing: Integrated cartridge mechanical seal with engineered flush piping plans for absolute containment.
  • Rigid Structural Base: Heavy-duty fabricated steel baseplate fully compliant with API 610 nozzle load requirements.
