About this product

Product information from the supplier.

Our Malleable Iron Pipe Fittings featuring advanced Electrophoretic Coating represent a pinnacle of metallurgical engineering, designed for environments where corrosion resistance and structural integrity are non-negotiable. By integrating high-strength KT30-6 malleable cast iron with a sophisticated triple-protection system, these fittings provide a seamless, leak-proof solution for complex piping networks.

Engineered for precision, these fittings utilize mathematical conical transition curves and 6g/6H grade thread accuracy to ensure optimal flow dynamics and effortless installation. Whether deployed in high-pressure industrial lines or critical fire protection systems, our electrophoretic technology eliminates dead angles and provides a uniform protective barrier that far surpasses traditional galvanization.

Frequently Asked Questions

Q: What makes electrophoretic coating superior to hot-dip galvanizing for iron fittings?

Electrophoresis uses an electric current to deposit the coating, ensuring a perfectly uniform thickness even in deep threads and internal cavities, whereas galvanizing can leave "dead angles" or uneven drips. It also offers significantly higher salt spray resistance (500+ hours).

Q: Is the KT30-6 malleable iron suitable for high-pressure HVAC systems?

Yes, our fittings are rated for PN25 and can withstand working pressures up to 3.2MPa, which is 40% higher than the industry average, making them ideal for high-pressure hot water circulation in HVAC networks.

Q: How do I prevent the coating from cracking during installation?

To preserve the coating, we recommend using a protective shim when using pipe wrenches or chain clamps, and strictly controlling the tightening torque within the specified standard range.

Q: Are these fittings compliant with environmental regulations for green building?

Absolutely. Our process is free of chromates and harmful heavy metals, and we implement a 100% production wastewater recycling system, aligning with strict global environmental standards.

Q: What is the recommended sealant for these electrophoretic fittings?

We strongly recommend using PTFE raw material tape, wrapped in the same direction as the threads, to ensure a reliable, leak-proof seal without damaging the epoxy layer.

Q: In what temperature ranges can these malleable iron fittings operate?

Our fittings are designed for extreme versatility, maintaining structural integrity and coating adhesion across a temperature range from -30℃ to 120℃.
