Step 1: Flange Specifications
Where Flanges Are Used in Kurnool
Pumped storage, lift irrigation and pipelines dominate here, which means large diameters, lower pressures and drilling standards that must match imported valves and pumps. Kurnool's expanding renewable energy and irrigation infrastructure—anchored by the Greenko Pinnapuram 1,200 MW integrated renewable energy storage project and the Handri-Neeva Sujala Sravanthi (HNSS) lift irrigation canal system—generates strong demand for high-pressure penstock bypass flanges and heavy water mains. Remax supplies Class 300 and Class 600 ASTM A105 weld neck forgings, custom large-diameter IS 6392 plate flanges, and zinc-galvanised utility flanges for solar power washwater systems across Panyam and cement plants in Dhone and Bethamcherla.
| 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 |
Materials Guidance for Kurnool 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. Forged construction up to 24 inches; fabricated or plate-machined for larger diameters.
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 up to 2,000 mm outer diameter for plate flanges, and up to 24 inches for forged pressure classes..
| 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
Manufacturing quality for Kurnool focuses on high-head hydraulic penstocks, solar park water networks, and cement clinker dust resistance. For Greenko Pinnapuram pumped-storage penstock bypass headers, heavy forged weld neck flanges in ASTM A105 and A350 LF2 are checked via ultrasonic testing and magnetic particle inspection to eliminate subsurface forging anomalies. Large-diameter lift irrigation flanges for the Handri-Neeva project undergo strict flatness and bolt-hole alignment checks per IS 6392 and AWWA C207. Cement manufacturing units across Dhone and Betamcherla receive heavy-hub abrasive-resistant slip-on flanges stamped with certified heat numbers and backed by EN 10204 3.1 chemical and physical reports.

Delivery to Kurnool Sites
Road dispatch from Mumbai reaches Kurnool city and Orvakal in typically 4-6 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. Located along NH44, Kurnool receives fast 24 to 36 hour road dispatches from Mumbai. Consignments are packed in steel-strapped wooden cases with complete project line tags matching your piping isometric drawings.
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.
Price Guidance for Kurnool Buyers
Pricing for Kurnool solar installations, Greenko Pinnapuram pumped storage packages, and cement plant operations is determined by forging tonnage, pressure rating (Class 150 to Class 2500), and test certification needs. Heavy forged weld neck flanges for high-head penstocks and high-grade carbon steel slip-on flanges for cement conveyor systems are quoted with transparent fabrication breakdowns. Direct supply from Remax Forge ensures Kurnool buyers avoid stockist commissions. Our written quotes clearly detail ex-works price, transport to Kurnool site, and 18% IGST.
* 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.
