PN16 Flanges: Reliable Pipe Connection Solutions for Medium-Pressure Applications
PN16 Flanges are widely used in industrial piping systems for connecting pipes, valves, pumps, and other equipment while ensuring a secure, leak-proof seal. Designed to withstand a maximum working pressure of 16 bar, PN16 flanges are commonly used in water treatment plants, chemical processing, HVAC systems, power generation, food processing, and general industrial pipelines.
At AstroForge Fitting Industries, we manufacture and supply premium-quality PN16 Flanges in various materials, sizes, and international standards to meet the demanding requirements of industrial applications. Our flanges are precision engineered to provide excellent dimensional accuracy, corrosion resistance, and long service life under medium-pressure operating conditions.
Types of PN16 Flanges We Offer
- PN16 Slip-On Flange: PN16 Slip-On Flanges are easy to install and economical. They slide over the pipe before welding, making them suitable for water supply systems, chemical plants, and low to medium-pressure pipelines.
- PN16 Weld Neck Flange: PN16 Weld Neck Flanges feature a long tapered hub that provides superior strength and reduces stress concentration. They are recommended for applications involving pressure fluctuations and elevated temperatures.
- PN16 Blind Flange: PN16 Blind Flanges are designed to seal the end of piping systems or pressure vessels. They provide excellent leak protection and allow future pipeline expansion or maintenance.
- PN16 Socket Weld Flange: PN16 Socket Weld Flanges are ideal for small-diameter piping systems operating under moderate pressure. Their socket design provides a strong and reliable welded connection.
- PN16 Threaded Flange: PN16 Threaded Flanges are manufactured with internal threads, allowing installation without welding. They are commonly used where welding is impractical or hazardous.
- PN16 Plate Flange: PN16 Plate Flanges are flat circular flanges widely used in water distribution systems, wastewater treatment plants, and general industrial piping applications.
- PN16 Lap Joint Flange : PN16 Lap Joint Flanges are used together with stub ends, allowing easy dismantling and alignment. They are preferred for systems requiring frequent maintenance.
- PN16 Reducing Flange: PN16 Reducing Flanges connect pipes of different diameters while maintaining pressure integrity. They are ideal where pipeline size transitions are required.
- PN16 Tongue and Groove Flange: PN16 Tongue and Groove Flanges provide superior sealing performance through their matching tongue and groove faces, making them suitable for critical sealing applications.
- PN16 Square Flange: PN16 Square Flanges are commonly used in hydraulic systems and specialized industrial equipment where square mounting configurations are required.

FAQs - PN16 Flanges
PN16 Flanges are pipe flanges designed to withstand a maximum working pressure of 16 bar. They are commonly used to connect pipes, valves, pumps, and other equipment in medium-pressure piping systems.
PN stands for Pressure Nominal, and PN16 indicates that the flange is rated for a nominal pressure of 16 bar at standard reference temperatures. The actual allowable pressure may vary depending on the material and operating temperature.
PN16 Flanges are commonly manufactured according to EN 1092-1, DIN, BS 4504, and IS 6392 standards, ensuring compatibility with European and international piping systems.
PN16 Flanges are available in various materials, including Carbon Steel, Stainless Steel, Alloy Steel, Duplex Steel, Super Duplex Steel, Monel, Inconel, Hastelloy, Titanium, and Alloy 20, depending on the application requirements.
Common types include Slip-On Flanges, Weld Neck Flanges, Blind Flanges, Socket Weld Flanges, Threaded Flanges, Plate Flanges, Lap Joint Flanges, Reducing Flanges, Tongue & Groove Flanges, and Square Flanges.
PN16 Flanges are widely used in water treatment plants, chemical processing industries, HVAC systems, power plants, food processing facilities, marine applications, fire protection systems, and general industrial piping.
PN16 Flanges are typically available in sizes ranging from DN15 (½ inch) to DN600 (24 inches), with larger sizes available depending on project specifications and manufacturing standards.
PN16 Flanges are available with several facing options, including Raised Face (RF), Flat Face (FF), Ring Type Joint (RTJ), Tongue & Groove (T&G), and Male & Female (M&F) to suit different sealing requirements.
Quality-tested PN16 Flanges undergo dimensional inspection, visual inspection, PMI (Positive Material Identification), ultrasonic testing (UT), hydrostatic testing, and other quality checks to ensure compliance with international standards.
AstroForge Fitting Industries manufactures high-quality PN16 Flanges using premium raw materials and advanced machining processes.
