PETROSYSTEM SRL: the intrusive pig signallers’ Italian manufacturer

PETROSYSTEM SRL, active in the pipeline cleaning and maintenance sector for over thirty years, recently opened its brand-new premises in Albano Laziale, Rome (Italy). Following intensive engineering development, can proudly present its range of intrusive pig signallers’ models to cover any potential installation and service challenges.

Intrusive pig signallers

Designed to provide simple and effective pig passage detection, intrusive pig signallers have been widely used, not only in oil & gas but in the pipeline and process industries for many years. Supplied with traditional visual flag, they can be combined also with electrical indication to send signals to client’s remote-control rooms.

Intrusive pig signallers are still the only devices in the market capable of detecting any kind of pigging tool from simple foams to ILIs, under any service condition (liquid or gas) and without having to add any additional magnets, transmitter or other external element to the pigs the operator or service companies may have in place.

MEKA Model – With self-locking flag system, specially designed for installations in which the signaller is going to be installed at any angle in the pipeline, on vertical pipes or launchers or in any location subject to strong winds or other environmental challenges, makes sure flag will remain in the closed position and only positive pig passage will activate it.

SIGNA Model – Our most versatile model, in any class rating, with or without isolation valves, for installation above or underground at any depth, can be tailored to suit any client specification, materials, connecting flange face or pipeline service.

All our signallers incorporate omni-directional trigger, and the mechanical and electrical signals are independent. All our models can still send electrical pig passage confirmation to control room even if visual flag has not been reset.
