Why Flowline Outperforms Trading Resellers: Our Captive Foundry

Unlike trading entities who purchase generic pumps from third-party shops, Flowline Pumps operates a dedicated 750 T/Yr captive steel casting foundry in Coimbatore (commissioned 2018). Certified under ISO 9001:2015 and European Pressure Equipment Directive (PED 2014/68/EU), our metallurgical engineers control chemical composition, grain boundaries, and wall thickness from raw charge to final assembly.

  • Optical Spectroscopy: 32-Element Spectrometer with direct Nitrogen analysis to ensure exact phase balance in Duplex steels.
  • Calibrated Heat Treatment: 1-Ton electric furnace with water quenching, verified to API 6A Annex M, ASTM A991, and NORSOK M650.
  • Non-Destructive Testing: Certified in-house NDT Level II inspectors conducting Radiography (RT), Ultrasonic (UT), and Dye Penetrant (DPT).
  • 100% Hydrostatic Pressure Testing: Every pump casing hydro-tested to 1.5x design pressure before dispatch.
