Product Formation

Fire diaphragm pressure gauges are made via a standard process focusing on precision and fire safety. The core diaphragm uses corrosion-resistant, high-elasticity materials (316L stainless steel or fluororubber) to withstand water, air, or dry powder residues. The case (forged brass/aluminum alloy) is precision-cast and anti-rust treated (chrome plating/painting) for durability in humid environments.

Key parts are precision-processed: the diaphragm is stamped and heat-treated for uniform elasticity; internal gears/linkages are CNC-machined to reduce error. Threaded interfaces (NPT1/8, M10×1) match fire equipment standards for tight connection.

Each gauge passes tests: pressure calibration (±1.6% error), diaphragm durability (10,000+ pressure cycles), and environmental adaptability (-20℃ to 70℃, 95% humidity). Qualified gauges get clear scales (psi/bar) and shock-proof packaging.
