What We Do
Complete Manufacturing & Fabrication Solutions
From precision machining to specialized welding and complete testing, Harsha Flow Technologies delivers end-to-end solutions for valves, flanges and critical industrial components.
01
High Precision CNC Machining
Automated CNC, HMC, VMC and VTL facilities for tight-tolerance, high-value machined components, produced through state-of-the-art techniques and rigorous inspection.
02
Cladding & Overlaying
Stellite overlay and hard facing on valve bodies, discs and seat rings, ensuring superior wear and corrosion resistance for severe-service applications.
03
Special Welding Expertise
GTAW (TIG), GMAW (MIG), SMAW (Stick), PAW & PTAW (Plasma Arc) and Submerged Arc Welding (SAW), carried out to ISO / ASME / EN standards.
04
Precision Fabrication
Heavy fabrication above 5 tons, bending and rolling, gas and laser cutting for structural and pressure-part manufacturing.
05
Assembly with Controlled Processes
Dedicated assembly units following controlled, documented processes so every valve and component leaves the shop floor built to spec.
06
Finishing
Surface finishing operations that bring machined and fabricated components to their final dimensional and cosmetic specification.
07
Complete Inspection & Testing
Coordinate Measuring Machine (CMM) and full testing facilities validate every component before it leaves the factory.
