DELCO Stainless Steel Plate Flange, HG/T 20592 Type PL PN6-PN40
Manufactured in strict accordance with HG/T 20592 and EN 1092-1 standards, this Plate Flat Welding (PL) flange features a precision-machined Raised Face (RF) for optimal gasket seating. Constructed from high-grade SS304/SS316L, it serves as a critical connection point for corrosive chemical and water treatment pipelines.
Features
A cost-effective, forged stainless steel mating flange designed for secure, leak-free integration of valves and piping equipment.
✅Standard Compliance: Fully compliant with HG/T 20592-2009 specifications, ensuring dimensional interchangeability with DIN and ISO PN10/PN16 mating flanges for global project compatibility.
✅Raised Face (RF) Sealing: The serrated raised face surface increases friction and gasket compression, providing a tighter seal than flat face designs when connected to heavy-duty Butterfly Valves.
✅Superior Material Quality: Forged from certified ASTM A182 F304/F316 stainless steel, offering exceptional resistance to intergranular corrosion and oxidation in acidic or saline environments.
✅Precision Machining: CNC-finished bore and bolt holes guarantee precise alignment, reducing installation time and eliminating bolt stress caused by misalignment.
✅Versatile Application: The slip-on plate design allows for easy welding to the pipe end, making it an ideal counter flange for connecting pumps, meters, and flow control devices.
