Malleable iron undergoes a heat treatment process that removes carbon and increases ductility, making it much more resistant to impact and fractures than standard grey cast iron.
The high-temperature blackening creates a dense, chemically stable oxide layer that prevents oxygen from reaching the base metal, effectively stopping rust and corrosion in moist environments.
Yes, these fittings are rated for PN10 to PN16 pressure levels, making them suitable for a wide range of industrial fluid and gas transmission systems.
We recommend applying PTFE tape (Teflon tape) or a high-quality pipe sealant to the external threads and tightening with a double-wrench method for a leak-free seal.
They are widely used in building HVAC, fire protection networks, industrial water treatment plants, and agricultural irrigation systems.
Verify the external diameter of both pipes you intend to connect; then select the corresponding DN (nominal diameter) combination, such as DN25x20 for a transition from 25mm to 20mm.
