FAQ
Q: How long can brass material remain rust-free in a humid environment?
A: Professional brass material and surface polishing anti-rust treatment ensure that the product remains rust-free for over 15 years in a regular humid environment. Under long-term contact with water sources, it can still ensure a normal service life of 8 to 10 years, far exceeding the 3 to 5 years service life of galvanized materials.
Q: What should be noted when using the product in extremely cold regions?
A: Brass material has excellent low-temperature adaptability and does not affect its use in an environment of -20℃. Suggestion:
Apply low-temperature grease to the threaded areas before installation
Regularly check the elasticity of the sealing ring (it is recommended to do so every six months)
In extremely low-temperature environments, the anti-freezing sealing ring version we provide can be selected
Q: Why was brass chosen instead of stainless steel?
A: Brass has irreplaceable advantages in the field of fire protection:
Self-lubricating property: The thread engagement is smoother and less likely to get stuck
Good ductility: It has a buffering capacity under sudden water hammer impact
Convenient maintenance: It can still be easily disassembled after long-term use
Cost balance: Achieving the best equilibrium between performance and price
