LNG & Gas Processing Application
Large-diameter conical strainers provide practical protection for LNG compressor stations and gas-processing equipment during construction, flushing, commissioning, start-up and recommissioning.
Monarch Asia Pacific manufactures custom cone strainers in Australia for demanding pipeline services where high flow, mechanical strength, adequate open area and reliable debris retention are critical.
LNG and gas-processing systems contain high-value equipment that can be sensitive to solid contamination. Compressors, pumps, metering equipment, valves, seals and instrumentation can all be affected by foreign material carried through the pipeline.
New construction, shutdown work, pipeline tie-ins, upgrades and maintenance can introduce or disturb debris such as weld slag, rust, mill scale, gasket fragments, coating particles and general construction residue. If this material reaches critical equipment it can contribute to erosion, blockage, seat damage, premature wear and unplanned downtime.
An inline conical strainer provides a simple mechanical barrier within the pipeline, capturing damaging solids while maintaining the flow area required for flushing, testing and commissioning.
Why Conical?
Conical strainers, including truncated cone designs with inverted sections, can provide significantly greater screening area than a flat plate installed within the same pipe bore. The increased filtration area helps reduce clean pressure drop, provides greater dirt-holding capacity, and can extend the operating period between inspection and cleaning.
This is particularly valuable in large-bore LNG and gas pipelines where high flow rates and significant debris loads can make a small or highly restrictive element impractical.
Cone length, included angle, screen construction and reinforcement can be adjusted to suit the available installation space, required open-area ratio and mechanical duty.
Cone strainers may be used at several stages of LNG and gas infrastructure projects.
Capture construction and fabrication debris while new systems are being cleaned and prepared for service.
Protect downstream equipment while debris is progressively removed from large process and utility lines.
Provide temporary equipment protection while the cleanliness and stability of the process system are established.
Reduce contamination risk following maintenance, modifications, brownfield tie-ins and recommissioning work.
Large-diameter cone strainers should be designed around both process performance and mechanical integrity.
The filtration layer can be tailored to the expected debris and mechanical duty.
Robust construction for coarse debris retention and high mechanical strength.
A structural perforated cone supporting a finer mesh layer where smaller particles must be retained.
Alternative screen constructions can be considered where specified by the process or project design.
Many LNG cone strainers are installed for a defined commissioning or start-up period and removed once acceptable pipeline cleanliness has been demonstrated.
In other applications, the cone may remain in service for an extended period as part of the overall mechanical protection strategy. Longer-duration service places greater emphasis on clean pressure drop, expected dirt loading, reinforcement, access for inspection and the consequences of progressive blockage.
The final arrangement can be adapted where standard cone geometry does not provide the required area, support or installation fit.
Custom perforated or mesh-lined cones for temporary and commissioning protection.

Useful where a shorter overall length or increased screen area within an installation envelope is required.
View OptionsAdditional screen sections can increase available area where overall cone length is constrained.
View OptionsSupport rings, structural backing and other reinforcement can be added for demanding differential-pressure duty.
View OptionsThe more complete the operating information, the better the cone can be matched to the process and mechanical requirements.
Monarch can work from project datasheets, drawings, existing strainer details or a defined set of process conditions.
Australian Manufacture + Workshop Support
Monarch Asia Pacific combines industrial filtration experience with in-house sheet-metal, cone-forming, welding and fabrication capability from our Brendale workshop.
This is particularly useful for large-diameter or project-specific conical strainers where standard catalogue products do not provide the required dimensions, open area, materials or structural strength.
