Core Features
✅ Superior Material—Selected malleable cast iron, combining high strength and good toughness, impact resistance, pressure resistance, and mechanical properties far exceeding ordinary cast iron.
✅ Long-lasting corrosion resistance – A unique high-temperature blackening process forms a dense and stable iron oxide protective layer on the surface, providing significant rust resistance and eliminating the need for secondary galvanizing.
✅ Precision and reliability – Threads are precisely machined using CNC machine tools, ensuring accurate dimensions and a tight fit, guaranteeing excellent sealing at the connection and eliminating the risk of leakage.
✅ Economical and practical – Performance comparable to some steel components, but with a more cost-effective option, and is robust and durable with low total life-cycle costs.
✅ Complete specifications – A comprehensive product line covering various specifications and types from DN8 to DN100, meeting most pipeline installation, branching, turning, sealing, and diameter reduction needs.
Application Areas
• Building water supply and drainage, fire sprinkler and HVAC systems
• Industrial equipment cooling water, compressed air, and low-pressure steam piping
