| Feature | Threaded Flange | Welded Flange | Traditional Joints |
|---|---|---|---|
| Installation Speed | Ultra-Fast | Slow (Welding required) | Moderate |
| Labor Cost | Low | High (Certified Welder) | Moderate |
| Maintenance | Easy (Unscrew) | Hard (Cut & Reweld) | Moderate |
| On-site Risk | Safe (No Fire) | High (Fire Hazard) | Low |
| Life Cycle Cost | Efficient | Expensive | Moderate |
Threaded flanges offer a non-welding connection, which significantly reduces installation time and eliminates fire hazards on site. They are also much easier to disassemble for maintenance or system upgrades.
Hot-dipped galvanizing generally provides a thicker protective layer than electrical galvanizing, making it more suitable for harsh outdoor or industrial environments with high moisture.
Yes, our cast iron flanges are designed with high strength and are thoroughly stress-tested to ensure reliability in water, gas, and firefighting systems.
We support all major international standards including BS, NPT, and DIN to ensure compatibility with piping systems worldwide.
Absolutely. Due to their aesthetic industrial look and sturdy structure, many customers use our fittings to create custom lamps, bookshelves, and other DIY furniture.
We utilize professional high-precision machinery for machining and conduct mandatory stress tests and rust-resistance checks on every unit before it leaves our facility.
