Flame Arrestor Inspection
Certified inspections of all flame arrestor types — deflagration, detonation, in-line, and end-of-line — documented to API 2000, NFPA 67, and EN ISO 16852 standards.
Flame arrestors are passive safety devices installed in piping systems, storage tanks, and processing equipment to prevent the propagation of flames from one side of the device to the other. When functioning correctly, they protect your facility from catastrophic fire and explosion events. When they fail — due to corrosion, plugging, mechanical damage, or inadequate maintenance — the consequences can be fatal and facility-wide.
At Precision MCS (PMCS), we provide certified flame arrestor inspection services designed to ensure every unit in your facility is performing as intended, documented to industry standards, and compliant with applicable regulations. Our inspectors bring deep practical experience in petrochemical, oil and gas, refining, and chemical processing environments where flame arrestor reliability is a non-negotiable safety requirement.
Regulatory bodies including OSHA, the EPA, and international standards organizations require periodic inspection and maintenance of flame arrestors in facilities handling flammable and combustible vapors. Beyond regulatory compliance, flame arrestors that are blocked, corroded, or incorrectly installed represent a direct threat to personnel safety and operational continuity. A single failed unit in a vapor recovery system, storage tank vent, or process line can allow a flame front to travel at explosive velocities into protected equipment — with devastating results.
PMCS takes flame arrestor integrity seriously because we understand what is at stake. Our inspection services are not a checkbox exercise. They are a thorough, engineered assessment of each device's condition, installation, and operational suitability for the service it is in.
PMCS inspects all categories of flame arrestors, including deflagration arrestors designed to stop lower-speed flame fronts, detonation arrestors engineered for high-speed explosive events, in-line arrestors installed within pipeline runs, end-of-line arrestors mounted at tank vents and open pipe ends, and combination units designed for specialized process applications. Each type has distinct inspection requirements based on its design, the vapors it handles, and its position in the system.
PMCS flame arrestor inspections are conducted in alignment with the following industry standards and codes: API Standard 2000 (Venting Atmospheric and Low-Pressure Storage Tanks), NFPA 67 (Guide on Explosion Protection for Gaseous Mixtures in Pipe Systems), EN ISO 16852 (Flame Arrestors — Performance Requirements, Test Methods, and Limits for Use), and manufacturer-specific inspection and maintenance guidelines. Our inspectors are trained to apply these standards in the field and document deviations clearly and accurately.
A standard PMCS flame arrestor inspection covers: a complete visual and physical assessment of the arrestor housing, element, and end connections; corrosion evaluation including internal element degradation and external body corrosion; flow obstruction check to identify plugging, fouling, or biological growth within the element matrix; installation verification confirming correct orientation, appropriate location relative to ignition sources, and proper support; review of service history and previous inspection records where available; and a fully documented inspection report delivered on-site before our inspectors leave.
Every report includes photographic evidence, findings by location, corrective action recommendations, and a fitness-for-continued-service determination. We do not issue vague summaries — we give you the information you need to make maintenance decisions and satisfy auditors.
PMCS operates on a flat-rate pricing model for flame arrestor inspections. You receive one clear price before work begins, and that price does not change regardless of inspection duration, findings, or the level of documentation required. File review and audit support are included in the inspection cost. We believe transparent pricing is fundamental to a trustworthy inspection relationship.
PMCS provides flame arrestor inspection services to refineries, chemical plants, petrochemical facilities, natural gas processing plants, tank farms, marine terminals, pharmaceutical manufacturing operations, and any facility with flammable vapor handling systems. Whether you operate a single tank or a complex multi-unit processing facility, PMCS has the experience and resources to support your flame arrestor compliance program.
