stainless steel flanges DIN 316L
Key Features & Benefits of Our Flanges
Superior Sealing: Machined to exact tolerances with precise sealing surfaces to guarantee a perfect seal with the appropriate gasket, preventing leaks even under high pressure and temperature fluctuations.
Material & Corrosion Resistance: Fabricated from premium AISI 304 or 316L stainless steel, offering exceptional resistance to corrosion, oxidation, and harsh cleaning chemicals (CIP/SIP).
Durability & Pressure Rating: Built to withstand high pressure and mechanical stress, ensuring long-term reliability and safety in critical process environments.
Sanitary Design: Features a smooth, polished finish (Ra ≤ 0.8µm) on sealing surfaces to prevent bacterial adhesion and facilitate easy cleaning.
Versatility: Available in a comprehensive range of types, sizes, and international standards to meet any system design requirement.
Types of Flanges We Offer
Weld Neck Flanges: Ideal for high-pressure applications. The long tapered hub provides strength and reduces stress.
Slip-On Flanges: Easy to install and align, suitable for lower-pressure systems.
Blind Flanges: Used to blank off the end of a pipeline or vessel, allowing for future expansion.
Threaded Flanges: For connecting to externally threaded pipes without welding.
Sanitary Tri-Clamp Flanges: Designed for easy disassembly and cleaning in ultra-hygienic applications.

Industries and Applications
Our flanges are critical components in:
Food & Beverage: Connecting pipelines in processing systems for sauces, dairy, beverages, and brewing.
Pharmaceutical & Biotech: Ensuring airtight seals in water-for-injection (WFI) and process piping.
Dairy Industry: Used in homogenizers, pasteurizers, and filling lines.
Chemical Processing: Handling aggressive media in industrial chemical plants.
Oil & Gas: For utility and auxiliary lines in refining and production.
Frequently Asked Questions (FAQ)
Q: What is the difference between a Weld Neck and a Slip-On flange?
A: A Weld Neck flange is butt-welded to the pipe, offering high strength for high-pressure and high-temperature applications. A Slip-On flange slides over the pipe and is welded both inside and out, making it easier to align but suitable for lower pressures.
Q: How do I ensure a leak-proof flange connection?
A: A leak-proof connection requires three components: 1) A correctly aligned flange, 2) The proper gasket material for your media and temperature, and 3) Tightened to specification bolts following a cross-pattern tightening sequence.
Q: Can you provide flanges with custom drilling?
A: Absolutely. We are a manufacturer and can provide custom flanges with non-standard bolt circles, hole sizes, or materials to meet your specific OEM or project requirements.
