LNG & Industrial Gas

Leak-tight instrumentation components for LNG, cryogenic liquid, industrial gas, storage, vaporisation, compression, and distribution systems.

The operating context

What LNG & Industrial Gas asks of an instrument connection

LNG and industrial-gas facilities measure, isolate, sample, compress, store, vaporise, and distribute media that can be cryogenic, high pressure, or difficult to contain. Small-bore instrumentation connections are exposed to temperature extremes and gas molecules that reveal very small leak paths.

The system has to accommodate thermal contraction, protect tube grip, minimise joints, and provide dependable isolation for instruments and sample points. Material condition, assembly control, and the geometry of the seal all matter at low temperature.

Cryogenic sealing integrity

Fittings and valves must preserve their sealing interfaces as tube, ferrules, bodies, and stems contract during cool-down.

Gas-tight connection control

Precision components and repeatable assembly reduce leak paths in storage, vaporisation, compression, and distribution hook-ups.

Compact isolation and venting

Instrument interfaces need safe isolation, equalising, and vent functions without multiplying separate threaded connections.

Where Parflow fits

From process take-off to instrument

Parflow's catalog links cryogenic-capable tube fittings and instrumentation valves with manifolds, DBB assemblies, monoflanges, and accessories used across gas measurement and control.
