| A steel flange coupling is a fitting used to connect two pipeline sections via carbon steel flanges combined with a PP plastic body, providing reliable sealing, pressure resistance, and corrosion protection for water supply, drainage, and industrial systems. Construction: – Two - piece design: Most Penguin flange models are designed in a two - piece structure, allowing them to firmly grip the groove at the end of the steel pipe. – C-shaped gasket: Uses a specially designed rubber gasket to seal the contact surface between the flange and the pipe end, while also providing a certain level of flexibility. –Groove locking lip: The inner surface of the coupling has a raised lip that tightly fits into the rolled groove on the steel pipe, helping to withstand axial pulling force. Technical specifications: – Brand: Penguin – Origin: Malaysia – Body material: Polypropylene (PP) – Material: Ductile Iron ASTMA536 – Connection type: Flanged – Flange standards: BS, JIS, DIN – Standards: ISO 17885, ISO 3458, ISO 3459, ISO 3501, ISO 3503, ISO 7 – Gioăng làm kín: Cao su EPDM (dạng vòng đệm đặc chủng lắp trong rãnh mặt bích) – Working pressure: PN10, PN16 – Operating temperature: ≤ 80°C – Size: DN50–DN300 (or as required) Key Features: – Combines the mechanical strength of steel with the corrosion resistance of PP – High sealing performance, minimizing leakage – Lighter weight compared to fully metallic couplings – Easy installation, replacement, and maintenance Benefits: – Flexible transition: The only solution that enables quick connection of flanged equipment (such as gate valves and check valves) to piping systems using grooved coupling technology. – Excellent corrosion resistance in humid and wastewater environments – Quick installation and compatibility with various flange standards: No need to weld flanges onto the pipe, helping save space and installation time on site. – Long service life with stable operation – Easy installation and disassembly: Highly convenient for future maintenance, valve servicing, or equipment replacement. – Self – alignment capability: The coupling design allows for slight misalignment tolerance, making installation with fixed equipment (such as pumps) easier. – Cost-effective compared to all-metal couplings Disadvantages: – Temperature limitations; not suitable for high-temperature environments – Not recommended for strong chemicals unless material compatibility is confirmed – Lower impact resistance compared to fully metal couplings Applications – Pump stations: Connecting the suction/discharge side of pumps to the main pipeline. – Central valve assemblies: Connecting alarm valves and gate valves in fire protection. – Transition points: Between grooved steel piping sections and plastic/steel piping sections using conventional flanged connections. |
