Overview
Nipo Flanges— Manufacturers & Suppliers in India
Manibhadra Metals is a trusted manufacturer, supplier, stockist, and exporter of ANSI/ASME B16.47 Nipo Flanges in India. We supply Stainless Steel, Carbon Steel, Alloy Steel, Duplex, Super Duplex, Inconel, Monel, Hastelloy, and other special-alloy Nipo Flanges for branch connections in high-pressure and critical piping systems.
A Nipo Flange is a single-piece forged component that combines the functions of a Weld Neck Flange and a Nipolet. Since both sections are manufactured as one integral unit rather than welded together, the design provides improved strength, accurate alignment, reduced stress concentration, and reliable leak-resistant performance.
Our Nipo Flanges are available in ASME B16.5, ASME B16.47 Series A and Series B, EN 1092-1, EN 1092-2, DIN, AWWA C207, and MSS SP-44 standards. They can be supplied in Class 150, 300, 400, 600, 900, 1500, and 2500, as well as PN-rated configurations such as PN10, PN16, PN25, and PN40.
Manibhadra Metals manufactures Raised Face, Flat Face, RTJ, reducing, reinforced, and custom Nipo Flanges in standard and special dimensions. These products are widely used in oil and gas pipelines, refineries, petrochemical plants, pressure vessels, boilers, offshore systems, chemical processing units, and power-generation projects.
All Nipo Flanges can be supplied with dimensional inspection, PMI testing, ultrasonic testing, radiography, hydrostatic testing, EN 10204 3.1 or 3.2 Material Test Certificates, NACE compliance, and third-party inspection documentation according to customer and project requirements.

Overview
How Nipo Flanges Work
1
Single Integral Forging
The Weld Neck Flange and Nipolet outlet are machined from one forged billet no intermediate weld between them. This gives the assembly a continuous grain structure and eliminates the weakest point of the equivalent two-piece assembly.
2
Schedule-Matched Bore
The Nipolet end of the fitting is butt-welded directly into the run pipe wall typically at 90°. The outlet self-reinforces the branch opening in the run pipe, meeting ASME B31.3 and B31.1 branch reinforcement requirements without a separate pad.
3
Flange Connects Branch Spool
The Weld Neck flange face on the outlet connects directly to the mating branch spool, valve, or instrument. This turns a branch connection into a bolted, removable flanged joint ideal for control valves, safety valves, and instruments needing regular maintenance.
4
Fewer Welds, Less NDE
Replacing a three-weld assembly (Nipolet-to-pipe + Nipolet-to-WN + WN-to-spool) with a two-weld assembly (Nipoflange-to-pipe + flange joint) reduces radiography scope, weld records, and hydrostatic test circuit complexity.

KNOWLEDGE BASE
Frequently Asked Questions
What is a Nipo Flange?
A Nipo Flange is a one-piece forged branch connection combining a flange with a Nipolet-style outlet. Its integral construction provides a compact, strong, and leak-resistant connection for piping systems and pressure equipment.
Which standards and pressure ratings are available?
Nipo Flanges are available to ASME B16.5, ASME B16.47 Series A and B, MSS SP-44, EN 1092, DIN, AWWA C207, and other standards. Common ratings include Classes 150, 300, 400, 600, 900, 1500, and 2500, along with PN-rated configurations.
Which materials are used for Nipo Flanges?
Common materials include Carbon Steel ASTM A105/A105N, Stainless Steel 304/304L and 316/316L, Alloy Steel, Duplex, Super Duplex, Inconel, Hastelloy, Monel, Incoloy, Titanium, Copper Nickel, and other special alloys.
Are custom and reducing Nipo Flanges available?
Yes. Nipo Flanges can be manufactured in equal or reducing configurations with custom branch sizes, bore schedules, lengths, face types, drilling patterns, materials, and pressure classes according to customer drawings.
What tests and certificates are available?
Nipo Flanges can be supplied with EN 10204 3.1 or 3.2 Material Test Certificates, PMI, ultrasonic testing, radiography, hydrostatic testing, magnetic-particle inspection, NACE certification, and third-party inspection reports.
