Containment across changing duty
Connections must remain tight as units move through start-up, continuous operation, shutdown, and the temperature cycles between them.
Fittings, valves, manifolds, and instrument interfaces for refinery crude, reforming, treating, steam, sampling, and measurement duties.

A refinery depends on dense networks of pressure, flow, level, temperature, and sample connections across crude distillation, reforming, treating, utilities, storage, and loading. Each hook-up has to preserve process containment while giving instruments a dependable signal.
The service can combine hydrocarbons, steam, thermal cycling, vibration, and maintenance under strict permit conditions. Compact isolation, fewer leak paths, and clear bleed or vent functions make instrument work safer and faster during both operation and turnaround activity.
Connections must remain tight as units move through start-up, continuous operation, shutdown, and the temperature cycles between them.
Valve arrangements should let a technician isolate, bleed, and service a gauge or transmitter without dismantling more of the hook-up than necessary.
Integrated interfaces reduce threaded joints and simplify material control, inspection, installation, and replacement in crowded units.
Parflow supplies the connection, isolation, manifold, and accessory layers as one compatible system. DBB and monoflange configurations reduce separate joints at process interfaces, while tube fittings and instrument valves complete the route to the measurement device.
Typical application areas
Ratings vary by size, material, and end connection. Check the specification against your own service conditions before selecting.
