Flange Supplier in Vijayawada & the Amaravati Capital Region
Flanges manufacturer in Mumbai supplying power, industrial and capital-region projects around Vijayawada.
Step 1: Flange Specifications
What Vijayawada's projects specify
Demand around Vijayawada splits between high-temperature power-plant piping and very large, low-pressure water and building-services work. The two need completely different flanges, so start with the row that matches your job.
| Industry Sector | Local Sites & Projects | Where Flanges Are Used | Commonly Specified |
|---|---|---|---|
| Thermal power | Dr. Narla Tata Rao Thermal Power Station (APGENCO) at Ibrahimpatnam | Boiler feedwater and steam, cooling water, fuel oil, ash handling | A182 F11/F22 (F91 for higher-temperature steam) weld neck, Class 600-2500; A105 for cooling water and fuel oil; slip-on or plate flanges on lined ash-slurry lines |
| Industrial estates | Kondapalli Industrial Development Area, Autonagar workshops and body builders, the Mallavalli industrial park | Process piping, boilers and steam, compressed air, skids and fabricated assemblies | A105 slip-on and weld neck, Class 150-300 RF; 304L/316L for food-processing utilities |
| Capital city construction | Amaravati Capital Phase-I: the World Bank and ADB have committed US$1.6 billion, and contractors are mobilised on arterial roads, housing and government buildings and city-wide systems | Water mains and pumping stations, sewerage and drainage, fire-fighting and HVAC plant rooms in large buildings | Slip-on, blind and large-bore flanges drilled to AWWA C207, EN 1092-1 PN10/PN16 or IS 6392 as the tender specifies; A105 Class 150 for fire mains |
| Water & irrigation | Krishna river works around Prakasam Barrage, the delta canal system and municipal water supply | Pump discharge headers, valve chambers, surge and air-release branches | Large-diameter plate or slip-on flanges, PN10/PN16 or Class 150; blind flanges for future tap-offs |
Class 150 or PN16? The drilling mistake that stalls Vijayawada water jobs
Work around Vijayawada and Amaravati often mixes equipment from different standards: pumps and valves drilled to EN 1092-1 PN10/PN16, pipe specified to IS or AWWA standards, and fire-fighting packages built to ASME. An ASME B16.5 Class 150 flange and an EN 1092-1 PN16 flange of the same nominal size generally have different bolt circles and bolt-hole sizes, so they will not bolt together. Before ordering, check the drilling standard of the valve or pump you are mating to and put it on the enquiry - we machine to ASME, EN, IS or to your drawing.
Power-plant buyers face the opposite problem: pressure and temperature. For steam service, chrome-moly grades F11, F22 and F91 must be supplied in the heat-treated condition ASTM A182 requires, and the certificate should show it. Ask for the heat-treatment record with your quote.
Flange types we supply to Vijayawada
MS (carbon steel A105), SS 304L/316L and chrome-moly flanges ship from Mumbai to Vijayawada with certificates tied to each flange's heat number. Large-diameter and custom-drilled flanges for water projects are made to order up to 24 inches for B16.5 and larger sizes up to 48 inches for B16.47.
| Flange Type (ASME / DIN / IS) | Typical Use in Vijayawada |
|---|---|
| Weld neck (WNRF / WNRTJ) | Power-station steam and feedwater lines |
| Slip-on (SORF / SOFF) | Building fire mains and water pumping stations |
| Blind (BLRF / BLFF) | Tap-offs and end closures on capital-region water mains |
| Spectacle blind, spade & spacer | Fuel-oil and steam isolation during power-plant maintenance |
| Socket weld | Small-bore drains, vents and instrument lines |
| Threaded | Low-pressure utility branches in workshops and skids |
| Lap joint (with stub end) | Stainless process lines in food-processing units |
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.

Class 150 vs PN16: Why They Don't Bolt Together
View Full Video Transcript(Audio & step text)
Technical comparison: Class 150 versus PN16 flanges. Although both are rated for nominal low-to-medium pressure utility service, their bolt circle diameters, bolt hole counts, and outside diameters differ significantly across nominal pipe sizes. Direct connection without adapter spools or custom drilling leads to joint failure.
Delivery to Vijayawada, Kondapalli and Amaravati sites
Road dispatch from Mumbai reaches Vijayawada, Kondapalli, Ibrahimpatnam and the Amaravati capital area in typically 3-5 days after dispatch. Construction sites often have no receiving store, so add the site contact and unloading constraints (crane, access road, working hours) in the form and the transporter can plan around them. Invoices are raised with IGST as an inter-state supply from Maharashtra, and an e-way bill travels with every consignment above Rs 50,000. Certificates are matched to the heat numbers stamped on the flanges, which keeps the contractor's material reconciliation simple.
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.
Pricing water-project and power-plant flanges
Water-project flanges are priced mostly by weight and drilling; power-plant flanges by grade, class and testing. ASTM A105 carbon steel: ₹115–140/kg; SS 304L/316L: ₹380–580/kg; Alloy steel F11/F22: ₹230–330/kg Send the tender BOQ and we quote line by line, with freight to Vijayawada shown separately.
* Note: Raw material steel prices fluctuate with international billet indices. Line-by-line itemized quotations are issued for Vijayawada consignments upon receipt of flange size, rating, and quantity.

Flange questions from Vijayawada buyers
Detailed answers covering technical specifications, testing certifications, transit times, and commercial terms for Vijayawada.
We ship from Mumbai and do not use dealers or stockists in Vijayawada, so you buy directly from the manufacturer and receive the manufacturer's certificates with every delivery.
Yes. We quote against the contractor's approved specification and drawings, including large-bore and PN-drilled flanges for water, sewerage and pumping stations. If the package names a make list or third-party inspection, attach it to the enquiry.
Usually not - bolt circles and hole sizes differ for most sizes. Match the flange to the valve's drilling standard, or order a flange drilled to that standard.
Yes, in weld neck and other types, heat-treated as ASTM A182 requires, with certificates showing chemistry, mechanical results and heat treatment.
Typically 3-5 days in transit after dispatch; production time depends on grade and size and is stated in the quote.
Flange type, nominal size, pressure class or PN, facing (RF, FF or RTJ), material specification and grade, bore or schedule for weld neck flanges, quantity, delivery location, and any testing or certificate requirements. A BOQ or drawing upload covers all of it.
