About this product

Product information from the supplier.

The Malleable Iron Pipe Fitting Cross is a high-performance hub engineered for precision multi-point diversion and merging within complex pipeline architectures. Integrally cast from high-strength malleable iron, these crosses are designed to withstand rigorous industrial pressures while maintaining structural integrity, serving as the critical junction for four-way fluid distribution.

To ensure maximum longevity, our crosses undergo a sophisticated high-temperature hot-dip galvanizing process, creating a dense zinc-iron alloy layer. This advanced surface treatment provides superior corrosion resistance against water, air, and aggressive media, making them the ideal choice for HVAC, fire protection, and industrial water supply systems in both indoor and outdoor environments.

Frequently Asked Questions

Q: What is the main difference between hot-dip galvanized and electrical galvanized pipe fittings?

Hot-dip galvanizing creates a thicker, more durable zinc-iron alloy layer through high-temperature immersion, offering superior corrosion resistance for outdoor use, while electrical galvanizing provides a thinner, more uniform coating typically for indoor applications.

Q: Are these malleable iron crosses compatible with both BS and NPT threads?

Yes, we offer both BS and NPT thread standards to ensure compatibility with global piping systems. Please specify your required standard during the ordering process.

Q: What size range is available for the Malleable Iron Cross?

We provide a comprehensive range of sizes starting from 1/8" up to 6" (DN15 to DN150) to suit various industrial and residential requirements.

Q: Can these fittings be used for high-pressure fire protection systems?

Absolutely. Due to their high-strength malleable cast iron composition and rigorous pressure testing, these crosses are ideal for fire protection and industrial water supply.

Q: What is the advantage of using a "Reducing Cross" over an "Equal Cross"?

An Equal Cross maintains the same pipe diameter in all four directions, while a Reducing Cross allows you to transition from a larger main line to smaller branch lines, optimizing fluid flow and space.

Q: How do you ensure the leak-proof quality of the threaded interfaces?

We use precision-machining for all tapered threads and conduct rigorous pressure tests on every batch to ensure a tight, leak-free seal when installed with standard pipe fittings.
