Malleable iron pipe fittings (malleable cast iron pipe fittings) are a highly reliable and widely used connection solution in building internal water supply and drainage systems, including cold water, hot water, and sewage systems, due to their excellent comprehensive performance.
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.
