Expert Stainless Steel Flange Manufacturer and Exporter in India
At GT Metals and Tubes, we specialise in the design, manufacture, and export of premium stainless steel flanges (SS flanges) engineered for demanding industrial applications. With over 25 years of experience serving pharmaceutical, food & beverage, biotech, and other high-purity industries, our flanges are built to meet exacting standards of safety, hygiene, reliability, and performance.
What Are Stainless Steel Flanges?
Stainless steel flanges are components used to connect pipes, valves, pumps, and other equipment in closed piping systems. A reliable Stainless Steel Flange Manufacturer ensures these components provide secure sealing, facilitate assembly and disassembly, and maintain structural integrity under pressure. Flanges are crucial in systems where hygiene, corrosion resistance, and leak prevention are non-negotiable.
| Feature | What Sets Us Apart |
|---|---|
| High-Grade Materials | We use top grades of stainless steel (such as SS 304, SS 316 / 316L, etc.), which offer excellent corrosion resistance, mechanical strength, and suitability for stringent sanitary or high-purity environments. |
| Precision Machining & Manufacturing | Our flanges are manufactured using modern CNC machining, forging, and finishing processes to ensure dimensional accuracy, flatness, and surface quality. |
| Hygienic & Cleanable Surfaces | Flanges are often electropolished or mechanically polished to reduce surface roughness, prevent microbial adherence, and facilitate cleaning / sterilisation. |
| Standards & Compliance | We manufacture flanges in accordance with relevant international & national standards (ANSI, ASME, DIN, JIS, etc.), ensuring compatibility, safety, and regulatory compliance. |
| Custom Designs | Besides standard slip-on, weld-neck, blind, lap joint, threaded/flanged, etc., we offer bespoke designs to match your system’s geometry, pressure class, or special environmental requirements. |
| Rigorous Quality Control | Every flange undergoes stringent QC including dimensional checks, material verification, testing for flatness, dimensional tolerances, finish, and weld‐integrity if applicable. |
| Reliable Delivery & Support | With a strong in-house production facility & logistics capability, we ensure timely manufacturing, documentation (material test certificates, traceability), and post-sale service. |
Our Manufacturing Process
At GT Metal India, we follow a rigorous manufacturing process to deliver premium SS flanges and stainless steel fittings. It begins with careful raw material selection, where stainless steel billets and plates are tested for chemical and mechanical properties. The material is then forged or CNC-cut into desired shapes, followed by heat treatment to enhance strength and corrosion resistance.
Next, our advanced CNC machining ensures precise dimensions, smooth finishes, and accurate bolt-hole alignment. To protect against corrosion, flanges undergo pickling, passivation, or electropolishing, depending on application requirements. Every product is subjected to strict quality inspections and tests, including dimensional checks, hydrostatic testing, and non-destructive testing when required.
Finally, each flange is laser-marked with grade and specifications, then securely packed in wooden crates or pallets for safe global shipment. This streamlined process guarantees high-performance, durable flanges that comply with ASME, ASTM, DIN, and ISO standards.
Types of Stainless Steel Flanges
Common flange types manufactured in stainless steel:
Weld Neck Flange (WN) – high strength, ideal for high-pressure applications.
Slip-On Flange (SO) – economical, easy to install & align.
Blind Flange (BL) – used to close pipe ends or pressure vessel openings.
Socket Weld Flange (SW) – strong & reliable, for small bore piping.
Threaded Flange (TH) – no welding required, useful for low-pressure systems.
Lap Joint Flange (LJ) – used with stub ends, suitable for systems needing frequent dismantling.
Long Weld Neck Flange (LWN) – for high-pressure and high-temperature pipelines.
Reducing Flange – connects pipes of different sizes.
Orifice Flange – used with flow meters to measure fluid flow.
Spectacle Blind Flange – A safety device for maintenance and flow isolation.
