Flange Supplier in Kurnool
Flanges manufacturer in Mumbai supplying pumped-storage, irrigation, renewable and industrial projects around Kurnool.
Step 1: Flange Specifications
Kurnool's flange demand is mostly water
Pumped storage, lift irrigation and pipelines dominate here, which means large diameters, lower pressures and drilling standards that must match imported valves and pumps.
| Industry Sector | Local Sites & Projects | Where Flanges Are Used | Commonly Specified |
|---|---|---|---|
| Pumped storage & hydro | Greenko's Pinnapuram Integrated Renewable Energy Project (Panyam mandal): 1,200 MW closed-loop pumped storage with 1,000 MW solar and 550 MW wind in phase I | Cooling-water, drainage and dewatering systems, compressed air, lubrication and governor oil, bypass lines around inlet valves | A105 weld neck, slip-on and blind, Class 150-600; large-bore to ASME B16.47 or AWWA C207; 316L for oil and instrument lines |
| Solar parks | Kurnool Ultra Mega Solar Park (Panyam) and project sites across the district | Module-cleaning water networks, fire-fighting at substations | Galvanised slip-on and blind flanges, Class 150 or PN10/PN16 |
| Lift irrigation & water supply | Handri-Neeva and other lift schemes; municipal water supply | Pump discharge headers, surge vessels, air-release and scour branches | Large-diameter plate or slip-on flanges, PN10/PN16 or Class 150, IS 6392 where specified; blind flanges for future connections |
| Cement, minerals & industry | Cement and limestone units across the Kurnool-Nandyal belt; the Orvakal industrial area | Kiln and cooler utilities, fuel oil, compressed air, process water | A105 slip-on and weld neck, Class 150-300 RF |
Plate flange or forged flange? Choosing for Kurnool's water projects
Large water headers use a lot of flanges, so the construction method matters for cost.
Plate flanges are machined from steel plate and are economical for low-pressure water service at large diameters - typical of lift-irrigation and pipeline work at PN10/PN16. Forged flanges have a worked grain structure and are the choice where the design code, pressure class or cyclic loading calls for them, such as pump discharge branches on high-head equipment and pumped-storage auxiliaries at higher classes. Whichever you choose, specify the drilling standard - ASME B16.5/B16.47, AWWA C207, EN 1092-1 or IS 6392 - to match the valve or pump, and state the coating for buried or wet-well service.
Flange types we supply to Kurnool
Standard MS (A105) and SS ranges ship from Mumbai; large-bore and custom-drilled flanges are made to order 48 inches.
| Flange Type (ASME / DIN / IS) | Typical Use in Kurnool |
|---|---|
| Weld neck (WNRF / WNRTJ) | Pumped-storage auxiliaries at higher pressure classes |
| Slip-on (SORF / SOFF) | Lift-irrigation headers and solar-park water networks |
| Blind (BLRF / BLFF) | End closures and future branches on water mains |
| Spectacle blind, spade & spacer | Oil and water isolation during turbine maintenance |
| Socket weld | Small-bore oil, air and instrument lines |
| Threaded | Low-pressure module-cleaning water branches |
| Lap joint (with stub end) | Stainless lines that need frequent dismantling |
How every flange is made and checked
Every flange starts as a certified billet or bar whose heat number follows it through cutting, forging, heat treatment where the material specification requires it, CNC machining and drilling, and final marking of grade, class, size and heat number. Before dispatch we check dimensions against the governing standard and PMI, hardness, and ultrasonic testing, and issue material test certificates that tie each flange back to its heat. Buyer-nominated third-party inspection can witness any stage.

Delivery to Kurnool, Orvakal and project sites
Road dispatch from Mumbai reaches Kurnool city and Orvakal in typically 3-4 days; project sites in Panyam and other mandals may need a site contact and access details for heavy or long loads, which you can add in the form. Large-diameter flanges are palletised or crated to protect the faces in transit. Invoices carry IGST; an e-way bill travels with consignments above Rs 50,000; certificates match the heat numbers on each flange.
Consignments depart directly from our Mumbai facility via dedicated truck (loads > 5 MT) or reliable part-load carriers. Full transit updates provided.
Every order includes GST tax invoice with IGST, generated e-way bill for consignments above ₹50,000, detailed packing slip, and EN 10204 3.1 MTCs.
How large-bore water flanges are priced
Large water flanges are priced mainly by weight and drilling; pumped-storage auxiliaries by grade and class. ASTM A105 carbon steel: ₹115–140/kg; Large-bore AWWA / Plate: ₹125–155/kg; SS 304L/316L: ₹380–580/kg Upload your BOQ or drawings for a line-by-line quote.
* Note: Raw material steel prices fluctuate with international billet indices. Line-by-line itemized quotations are issued for Kurnool consignments upon receipt of flange size, rating, and quantity.

Flange questions from Kurnool buyers
Detailed answers covering technical specifications, testing certifications, transit times, and commercial terms for Kurnool.
We have no office in Kurnool; flanges are made and dispatched in Mumbai and delivered to your site, so drawings and drilling questions go straight to the machine shop.
up to 24 inches for B16.5 and larger sizes up to 48 inches for B16.47 Yes, drilled to ASME B16.47, AWWA C207, EN 1092-1 or IS 6392 as your specification requires, in plate or forged construction.
AWWA C207 covers steel flanges for waterworks service from 4 inch up to 144 inch at waterworks pressures; ASME B16.5 covers NPS 1/2 to 24 in Classes 150-2500 for process piping. Up to 24 inch, AWWA C207 Class B, D and E flanges share the bolt circle and holes of ASME Class 150 (Class F matches Class 300), so they usually bolt together - the differences are thickness and pressure rating. Above 24 inch, and against EN 1092-1 PN flanges, check the drilling before ordering.
Plate flanges are usually adequate and more economical for low-pressure water service; forged flanges are specified where the pressure class, code or cyclic loading requires them. Follow your design specification.
Yes - send the mating equipment's drilling standard or a drawing and we machine to it.
Typically 3-4 days in transit after dispatch; made-to-order large-bore flanges have their own production time, stated in the quote.
