Frequently Asked Questions
Q: What is the difference between Galvanized and Black surface finishes?
Galvanized finishes provide a protective zinc coating to prevent rust and corrosion, making them ideal for outdoor or moist environments. Black finishes are typically used for gas or oil lines where corrosion resistance is less critical.
Q: Which thread standards are available for Malleable Iron Unions?
We support all major international standards including BS (British Standard), NPT (National Pipe Thread), and DIN (German Industrial Standard) to ensure global compatibility.
Q: Can these unions be used for high-pressure systems?
Yes, our unions have a working pressure of 1.6 Mpa and are tested up to 2.4 Mpa, ensuring safety and stability under significant pressure loads.
Q: Why choose Malleable Iron over regular Cast Iron for pipe fittings?
Malleable iron undergoes additional heat treatment, which removes carbon and increases ductility, making it far less brittle and more resistant to impact than standard cast iron.
Q: What are the benefits of the Brass to Iron Seat option?
The Brass to Iron seat provides a superior sealing interface, reducing the risk of galling and improving the airtightness of the connection over time.
Q: How do I maintain these threaded union fittings?
Maintenance is simple due to the threaded design. You can easily unscrew the union to inspect the pipes or replace a section without the need for welding or cutting the entire line.
