Grooved Flange

Cost-Effective Total Ownership

While the initial cost of grooved flanges is competitive, their long-term value shines through reduced installation labor, no welding-related expenses (e.g., welding materials, labor, safety equipment), and minimal maintenance. The reusable design allows for easy disassembly and reinstallation during pipeline modifications or maintenance, avoiding the need to replace the entire flange. For large projects, the total cost of ownership is 20%-30% lower than that of traditional welding or threaded flanges.

Wide Compatibility & Versatility

Compliant with international standards (ANSI/AWWA C110, ASME B16.5, EN 1092-1), grooved flanges are available in sizes ranging from 1/2" to 48" (DN10-DN1200) and pressure ratings from Class 150 to Class 600 (PN6-PN40). They are compatible with various pipe materials (steel, stainless steel, ductile iron, PVC) and suitable for multiple applications, including fire protection systems, HVAC piping, water supply/drainage, petroleum & gas, chemical processing, and marine engineering.

Safe & Environmentally Friendly

The boltless and welding-free installation eliminates fire hazards, toxic fumes, and noise pollution associated with welding operations, ensuring a safer working environment and compliance with occupational health and safety regulations. The leak-proof design prevents media leakage, reducing environmental contamination risks. Additionally, the durable materials and reusable structure align with sustainable development goals, minimizing waste generation.
