Our Galvanized Iron Pipe Unions are engineered for high-performance piping systems, providing a secure and leak-proof connection that allows for easy disassembly and maintenance. Designed to meet rigorous industrial standards, these unions are ideal for water, oil, and gas transmission lines where durability and corrosion resistance are paramount.
Available in both BSP and NPT threading standards, these fittings ensure seamless integration into global piping infrastructures. The high-quality galvanized coating provides an essential barrier against oxidation, significantly extending the service life of the installation even in humid or chemically aggressive environments.

Frequently Asked Questions
BSP (British Standard Pipe) threads are generally parallel or tapered based on the standard (BSPP/BSPT), whereas NPT (National Pipe Tapered) threads are always tapered, providing a tighter seal through interference.
Galvanized iron is coated with zinc, which prevents rust and corrosion. This makes it far superior for water lines and outdoor installations compared to black iron, which oxidizes quickly.
Yes, provided the pressure rating of the specific union matches your system requirements. We offer various pressure grades including malleable iron and carbon steel options.
We recommend using high-quality PTFE seal tape or industrial pipe sealant on the threads before tightening to ensure a completely airtight and watertight connection.
While they can be physically connected via threads, we advise caution regarding galvanic corrosion. Using a dielectric union or appropriate sealant is recommended when mixing different metals.
Lead times vary by quantity and specifications, but typically range from 7 to 21 days. Please contact our sales team for a precise production schedule.
