High-Grade ASTM A182 F316 SORF Flange Manufacturer in India At Fair Price
Buying a pressure-rated joint shouldn't mean paying a trader's margin. We forge, roll, face and drill every piece in-house. Our units are based in Mumbai, India entirely. So the price you get is a works price. The certificate comes already attached to it. We stock ASME SA182 F316 plate flange blanks too. Cast-in SS316 puddle flange sets suit wall penetrations. ASTM A182 F316 exhaust flanges are copied from samples.
Our stock covers joints that refineries reorder most often. This includes weld neck, blind, lap joint flanges. Threaded flanges in 316 stainless are also available. Ring type joint sets suit higher-pressure packages well. Orifice flanges come with jack screws

Composition limits follow ASTM A182 for grade F316 forgings. Molybdenum is the element that separates it from 304.
SUS 316 Threaded Flanges Mechanical Properties
Room-temperature minimums are required for solution-treated F316 forgings. Reduction of area is 50% minimum on that piece.
AISI 316 Lap Joint Flanges Material Equivalent
The same alloy carries different designations across national systems worldwide. Buyers often quote one while the drawing lists another.

Kampala, Uganda316 Stainless Steel Blind flange Pressure Class Rating Chart
This pressure rating question comes up on nearly every Gulf enquiry. Here is the maximum allowable pressure at 38°C (100°F), per ASME B16.5.
One number never settles a flange selection on its own, so read the class alongside the design temperature:
Reading The Rating Correctly
Allowable pressure drops as metal temperature rises. A hot Class 300 joint isn't 49.6 bar anymore. Give us the design temperature and class. We'll confirm the derated figure before ordering.
SS 316 Pipe Flange Face Types & Surface Finish
Durban and Johannesburg buyers usually settle facing before class. The gasket already in their store decides it.
Facing finishes we machine and verify:
ASTM A182 Grade F316 Flange Testing, Inspection & Marking
Marking happens at the same stage, hard-stamped straight onto the outside diameter:
What Gets Hard-Stamped On The Rim
Marking follows MSS SP-25, so inspectors read it easily. Extra identification, like a PO line or tag number, is added on the outside diameter free of charge.

A UNS S31600 Weld Neck Flange carries bending load into the pipe. This is why hydrocarbon lines specify it over plate types. We bore the neck to match your isometric schedule. This ranges anywhere from SCH 5S through to XXS. We also supply matching blind flanges for isolation points. The full set arrives together on the same drawing.
