Our M.S. Flanges Manufacturing Process
Every M.S. Flange, E Table Flange, Pipe and Fitting manufactured at our Darukhana factory goes through a rigorous 4-stage process to guarantee consistent quality and IS-standard compliance.
Raw Material Sourcing & Verification
IS:2062 grade mild steel sourced exclusively from reputable Indian steel manufacturers. Every batch of raw material is verified for chemical composition, tensile strength and dimensional consistency before entering production. No compromise on material quality.
Precision Cutting & Blank Forming
Steel billets are cut to exact weight and dimensions using industrial cutting equipment. Flange blanks are formed by hot forging (for Forged Flanges) or precision turning of plate material. Each blank is checked for dimensional accuracy before proceeding to machining.
CNC Machining – Bore, Face & Bolt Holes
Flanges are machined on CNC and conventional lathes for precise bore diameter, face finish (3.2–6.3 Ra), and bolt hole drilling to exact IS:1538, ANSI B16.5 or customer-specified dimensions. This stage determines the dimensional accuracy critical for leak-proof assembly.
100% Quality Inspection Before Dispatch
Every finished M.S. Flange undergoes 100% dimensional inspection using calibrated gauges — OD, bore, PCD, bolt hole count and diameter, face finish and flange thickness are all verified. Material grade and surface finish are confirmed. Only approved products are dispatched. Material Test Certificates available on request.
