Siemens Maxum II FID/FPD Flame Arrester Hastelloy-C 1460006-001

Overview: A Critical Safety Component for Detector Venting

The Siemens Maxum II Flame Arrester Hastelloy-C, part number 1460006-001, is a safety-critical fitting used on the Flame Ionization Detector (FID) of the Siemens Maxum Edition II process gas chromatograph. Constructed from corrosion-resistant Hastelloy-C, this arrester threads into the FID bottom body, with its insert tube connecting to a union inside the analyzer oven, to prevent flame propagation out of the detector and back along the analyzer’s tubing – a mandatory protective measure on any combustion-based detector operating continuously in a hazardous-area process environment.

As an independent specialized supplier of Siemens Maxum Edition II analyzer spare parts, Seven Star LLC sources and supplies the flame arrester assembly 1460006-001 to refineries, gas plants, and petrochemical complexes across Oman and the wider GCC. Seven Star LLC helps maintenance teams keep the correct genuine Hastelloy-C arrester in stock to avoid safety-related downtime during FID servicing. Note that the Flame Photometric Detector (FPD II) does not use this part: per the Siemens Maxum Edition II Detectors Service Manual, the FPD takes its exhaust from the combustion chamber through a flameproof joint rather than through a flame arrester, and FPD hardware carries separate Siemens part numbers.

Working Principle: Flame Propagation Prevention

A flame arrester works by forcing the gas stream through a network of narrow passages or a porous matrix with dimensions small enough that heat is dissipated faster than a flame front can propagate through them. On the FID, this principle isolates the hydrogen-fuelled detector flame from the tubing that runs back into the analyzer oven – if a flashback event were to occur inside the detector body, the arrester’s narrow internal geometry quenches the flame before it can travel out of the detector and into the surrounding analyzer enclosure.

The choice of Hastelloy-C construction reflects the corrosive and thermally demanding environment inside an operating FID detector body, where the arrester is exposed to combustion byproducts and sustained elevated temperature. Hastelloy-C’s resistance to oxidation and chemical attack ensures the arrester’s narrow flame-quenching geometry remains dimensionally stable and free of corrosion product buildup over long service intervals, preserving both its safety function and its gas flow characteristics.

Engineering Design of the Flame Arrester Assembly

The 1460006-001 flame arrester is machined to the precise internal tolerances required to provide a certified flame-quenching gas path while introducing minimal restriction to the detector’s normal gas flow. Its compact fitting is sized for direct installation into the FID bottom body, matching the Maxum Edition II’s standard detector plumbing without requiring custom adaptation.

Because this arrester sits directly in the flame path of a continuously operating combustion detector, its mechanical integrity is central to the ongoing safety certification of the analyzer installation. Genuine Siemens-specified Hastelloy-C arrester assemblies are manufactured and tested to maintain their flame-quenching performance across the detector’s full operating temperature range, which is a key reason process safety and instrumentation teams standardize on the correct OEM part number rather than substituting generic flame arrester fittings.

Key Features

The Flame Arrester Hastelloy-C 1460006-001 is engineered to protect Flame Ionization Detector installations on the Maxum Edition II. Key characteristics include:

• Direct-fit replacement flame arrester insert assembly for the FID detector module on the Maxum Edition II.
• Hastelloy-C construction for resistance to corrosion and combustion byproduct attack.
• Precision-machined internal geometry engineered to quench flame propagation with minimal flow restriction.
• Rated for the sustained elevated temperatures present inside an operating flame detector body.
• Genuine Siemens Maxum II part number 1460006-001 for correct safety-certified fit.
• Installs and removes with a 9/16 in open-end wrench, seating against its flat washer in the FID bottom body.

Installation and Replacement on the FID

The Siemens Maxum Edition II Detectors Service Manual identifies the flame arrester as three related items within the FID assembly: the Flame Arrestor Insert Assembly that threads into the narrow end of the FID bottom body, the flat washer that seats beneath it, and the Flame Arrestor Bushing and arrester that complete the assembly. Replacement is a mechanical operation carried out with the detector cooled and the hydrogen supply isolated. Tubing is first disconnected from the FID flame arrestor insert tube inside the oven, after which the insert is removed from the FID bottom body using a 9/16 in open-end wrench.

Reassembly is where most field errors occur. Siemens is explicit that the threads of the FID flame arrestor must be clean and free of lubricant or any other substance before the insert and its washer are placed into the FID bottom body and tightened, because a contaminated thread can compromise the flameproof path that the arrester exists to maintain. The insert tubing is then reconnected to the correct connection union in the oven. Because the Siemens Maxum II Flame Arrester Hastelloy-C is part of the analyzer’s flameproof containment rather than a consumable measuring component, instrumentation teams across Oman and the GCC generally schedule its inspection and replacement into planned detector overhauls and turnaround safety inspections rather than waiting for a symptom to appear.

Industrial Applications

The flame arrester assembly is a required maintenance item wherever a Maxum Edition II analyzer is fitted with an FID, including refinery hydrocarbon monitoring, natural gas quality analysis, and total hydrocarbon measurement on petrochemical process streams. Because it is a safety-critical component, it is typically replaced as part of scheduled detector overhaul and safety inspection intervals rather than only on failure, making reliable stock availability important for planned turnaround maintenance.

Seven Star LLC supports refinery instrumentation teams, gas processing operators, and petrochemical maintenance departments across Oman, Muscat, Sohar, and the broader GCC region with sourcing of this and other Maxum Edition II detector safety hardware, helping analyzer houses maintain both measurement continuity and process safety compliance.
