Their main applications include domestic water branch pipes, sanitary ware connections, heating system piping, and some low-pressure drainage pipelines. Their core advantages make them highly favored in this field:
1. Superior Durability and Strength: Made of malleable cast iron, these fittings possess superior mechanical properties, capable of withstanding system water pressure and a certain degree of water hammer impact. They are robust, durable, and have a long service life, far superior to ordinary plastic pipe fittings.
2. Reliable Sealing Performance: Employing tapered thread connections, the tight fit between the metal parts, combined with suitable sealing fillers (such as PTFE tape), ensures a long-term, tight, leak-proof seal, guaranteeing safety and reliability.
3. Excellent Corrosion Resistance: The surface is typically hot-dip galvanized, forming an effective anti-corrosion barrier that effectively resists water and humid air erosion, ensuring the long-term stable operation of the piping system.
4. Mature Economic Efficiency and Versatility: Production technology is mature, specifications and models are extremely complete, procurement is convenient, and the cost-effectiveness is high. Installation techniques are widely used, making it suitable for on-site construction and post-construction maintenance in various building projects.
In summary, malleable iron pipe fittings, with their robustness, sealing, corrosion resistance, and economy, have become a classic and enduring choice in building water supply and drainage systems, providing a fundamental guarantee for the safety and stability of daily water use.
