Malleable iron undergoes a heat-treatment process (annealing) that removes internal stresses and increases ductility, making it far less brittle and more resistant to impact and high pressure than standard grey cast iron.
This process creates a dense oxide layer on the surface, which serves as a primary barrier against oxidation and rust, significantly extending the lifespan of the fitting in humid industrial environments.
Yes, with a pressure rating of PN10-PN16 and high structural strength, our malleable iron tees are ideal for compressed air piping networks and industrial cooling systems.
We recommend applying a sufficient amount of PTFE tape or professional sealant to all external threads and tightening them evenly using a double wrench system to avoid uneven stress.
The product is designed to operate reliably within a temperature range of -20℃ to 120℃, making it suitable for both cold water and moderate-heat HVAC applications.
Yes, all internal threads are precision-machined to align with national and standard industrial specifications, ensuring seamless integration with standard external thread fittings.
