A single faulty flange can cause the failure of the entire refinery and result in losses of millions of dollars. We manufacture robust and reliable stainless steel flanges that are leak-proof and can withstand high pressure to ensure that the system remains stable and maintenance is hassle-free in important conditions.
Stainless steel flanges are forged or machined pipe connectors used to assemble piping, valves, pumps, and equipment into a sealed and pressure-rated assembly. Unlike threaded or compression fittings, flanges allow for complete disassembly for inspection, maintenance, or replacement of parts, which is why they are the preferred choice in refineries, power plants, chemical processing plants, and shipbuilding. Our inventory includes every possible type of flange: weld neck, slip-on, blind, socket weld, lap joint, orifice, spectacle blind, ring joint, and long weld neck flanges, all of which are available in sizes ranging from ½" NB to 24" NB and pressure classes ranging from 150# to 2500#.
Sheetal Industries manufactures stainless steel flanges in a wide range of grades, sizes, and specifications to meet different industry requirements. Our product range includes austenitic stainless steel flanges in grades 304, 304L, 316, 316L, 316H, 310, 321, 321H, 347, and 904L, as well as duplex and super duplex stainless steel flanges.
With advanced manufacturing facilities and a distribution network, Sheetal Industries is capable of distributing stock flanges that are ready for shipment and custom-designed flanges made from non-standard materials. The organisation is capable of ensuring short lead times, material traceability, and documentation that meets international quality standards. This enables us to support its customers in the global market.

ANSI B16.5 Flanges Class 150, 300, 600 & 900 – Dimensions, Weight & Technical Data
Available Material Grades and Standards
- SS 304/304L (ASTM A312/A403): The most widely specified grade for process fluids; the low-carbon "L" variant prevents weld sensitisation.
- SS 316/316L (ASTM A312/A403): Molybdenum-bearing grade engineered to protect against pitting and crevice corrosion in chloride-rich or marine environments.
- SS 310 (ASTM A312 / A403): High-alloy grade (25% Cr, 20% Ni) providing stable oxidation resistance up to 1100°C for furnaces and kilns.
- SS 321 (ASTM A312/A182): A titanium-stabilised grade that prevents intergranular corrosion in weld heat-affected zones and is preferred for high-temperature heat exchangers.
Manufacturing Process Of Stainless Steel Flanges
Raw Material Selection
The manufacturing process of flanges begins with the careful selection of
raw materials.
Cutting and Shaping
Once the raw materials are selected, they undergo a precise cutting and
shaping process.
Finishings and Coatings
Coating the materials to a specific temperature ensures they become
malleable, facilitating the shaping process.
Welding and Joining
These processes ensure secure and leak-proof connections, enhancing the
reliability and longevity.
Finishing and Quality Control
After this the buttweld fittings undergo comprehensive finishing and
quality control procedures.
Packaging and Delivery
To reach their destination in pristine condition, we employ careful
packaging techniques.
