Frequently Asked Questions

What outlet connection standards are available for export fire hydrants?

Common outlet connections include BS336 (UK/Commonwealth), NIST (Middle East), KWS (Germany) and flexible flange options. We can supply hydrants with the connection type specified for your market.

What pressure rating should a municipal fire hydrant have?

Standard municipal hydrants are rated at PN16 (1.6 MPa), which covers most urban and industrial water supply networks. High-rise or high-demand industrial zones may require PN25 hydrants.

Are Wanlian hydrants available with UL or FM certification?

Yes, depending on the model and destination market. Contact our sales team with your project specification and target region so we can match the correct certification package.

Do outdoor hydrants have antifreeze protection?

Models such as the SS100 overground hydrant feature an automatic frost-drainage mechanism for cold climates. Anti-collision (SSFT100) and IoT smart (SS100ZN) variants are also available.
