 Trustindex verifies that the original source of the review is Google. Great company, great service and, more importantly, great people! Antony stopped in one day to service the previous business that had been in our location and, after a brief conversation, I chose to hire national fire systems. Since then he’s made that part of my job extremely easy by following up, providing the services he’s promised and making sure we’re fully compliant. Thank you, Antony!

Comprehensive Hydrostatic Testing & Cylinder Requalification

Hydrostatic testing involves filling the pressure vessel with water, placing it inside a specialized expansion chamber, and pressurizing it beyond its normal operating limit to measure volumetric expansion. Following strict DOT, NFPA, and California Title 19 standards, our fully equipped testing facility provides end-to-end cylinder requalification:

DOT-Certified Hydrostatic Testing: Accurate high-pressure water jacket testing for steel, aluminum, and composite cylinders to measure permanent and elastic expansion ratios.
Mandatory 5-Year & 12-Year Requalification: Timely pressure testing for $\text{CO}_2$ cylinders, stored-pressure fire extinguishers, clean agent cylinders, and SCBA tanks in accordance with regulatory intervals.
Complete Internal & External Visual Inspection: Thorough examination of interior and exterior cylinder walls for pitting, corrosion, stress cracks, thread damage, and structural wall thinning.
Valve Servicing & O-Ring Replacement: Complete disassembly, cleaning, re-threading, and valve component replacement to ensure gas-tight seals upon reassembly.
Precision Refilling & Recharging: Complete $\text{CO}_2$ cylinder refilling and fire extinguisher recharging services executed immediately following successful hydrostatic certification.
Official Stamping & Documentation: Proper DOT date-stamping, neck-ring installation, and compliant certification logging required for local fire inspectors and safety audits.
