Import Copper Alloy Glass Bulb Fire Sprinkler — Buy in Bulk from Supplier in China

The copper alloy glass bulb fire sprinkler supplied by Fujian Nanan City Guangwei Fire-Fighting Scie-Tech Co., Ltd. is a fire protection device built from a corrosion‑resistant copper alloy housing and a glass‑bulb heat‑sensitive actuator. The sprinkler activates when the bulb temperature reaches the design set point, releasing water through a calibrated orifice. The supplier states that the unit complies with ISO and CE safety standards. Typical flow rates for this type of sprinkler range from 15 to 30 L min⁻¹, suitable for medium‑size coverage areas.

Copper alloys used in fire sprinklers are usually classified under the ASTM C1023 standard, offering good thermal conductivity and mechanical strength. The glass‑bulb mechanism provides a rapid response to temperature rise, typically between 68 °C and 93 °C, which is common for residential and commercial installations. The housing is designed to resist corrosion in humid environments, extending service life beyond ten years under normal conditions. Standard connection sizes are 15 mm NPT, allowing easy integration into existing piping networks.

These sprinklers are installed in office blocks, warehouses, and multi‑family residential buildings where fire safety regulations require automatic suppression. Facility managers and building owners select them for reliable operation and compliance with local fire codes. The supplier offers flexible order quantities and ships under FOB or CIF terms, as indicated in the listing. Buyers should confirm current certifications and any required testing before finalising the purchase.
