A world of solutions

From concepts to complete systems.

PlantsGiving a shape to know how and to engineering in a seamless process.

Pre fabrication and fabrication of plants in one of our modern production facilities

in Italy, France, Hungary and China is a key part of our way of interpreting project

management.

Everything is happening under the same governing philosophy and with the same

patrimony of Human Resources. A set of international facilities bearing the most

qualifying approvals and manufacturing standards.

Pressure reducing stationsComplete packages of integrated systems for pressure control, gas treatment, gas metering engineered and built with the experience of the largest provider in the world. As manufacturer of pressure regulators, safety devices, valves, filters, heaters we know more than others the ideal conditions.

Nitrogen generationComplete packages, skid mounted, engineered and constructed with the traditional Pietro Fiorentini experience. A supply package covering coalescers, filters, chiller units, compressor.

Gas treatment packagesComplete turnkey plants for gas dehydration using either Glycol or fixed bed technology, sulphur removal units, Amine gas sweetening packages: whatever is the need of gas treatment we have a team of expert ready to work with you to study the best solution.

The heart of any gas system.

Pressure controlsInsuring constant gas flow in gas systems, always at the required pressure level

is our mission for more than 70 years. With the broadest range of models in the

market we have always an optimal solution for any gas application.

7

Pressure regulatorsAccuracy: precise pressure control is the main contributor to the smooth flow of gas into transmission lines. The wide range of models allow to choose always the most suitable product for each application, because 70 years of experience in the field tell us that not all applications have the same maintenance and silent operations.

Direct acting pressure regulatorsFast response: for several industrial applications this is the essential requirement. Our Staflux or Dival AP series are designed for this task that develop upstream.

Constant monitoring.

Safety devicesControlling the energy is our task through products developed to keep under

constant monitoring the process and the places and ready to stop any insurgent

possibility of danger.

Slam shut valvesShutting down the gas line in a blink of eye, when it is necessary only preventing the insurgency of any dangerous situation. This is the delicate and important task of slam shut valves requiring a professional selection among a wide range of models and types.

HIPPSWhenever there is a need of a higher degree of safety we have our HIPPS systems designed for. With pressure rating up to class 2500 and size up to 32” we can protect your plants or pipeline with solution specifically tailored for your application.

Relief valvesThe most traditional safety device is part of the tradition of Natural Gas industry. The pilot operated PV/S 782 range combining quick opening, accuracy and large capacity is today the ideal product to protect pipelines and large installations.

Controlling the pipeline.

Control valvesKeeping medium under control, quickly responding to any command this is the feature for which our valves are designed. Low noise, lock up in closed position, high rangeability are common feature to all our control valves.

Ball valvesValves are an essential part of any transmission pipeline. We know how important

they are in routine maintenance operations or during emergency situations.

Dedicated teams and know how are poured in the development of our control and

ball valves.

11

Ball valvesPietro Fiorentini is the traditional name for reliable and high performance products: our ball valves have been created under the same spirit and in the same manufacturing units. The models available cover all applications: fully welded or bolted body, medium pressure or extremely high pressure, sweet Natural Gas or aggressive mediums.

When details count.

Gas meteringAny improvement has a measurement at the base: Pietro Fiorentini diaphragm, rotary

or turbine gas meters provide the degree of accuracy necessary to an optimization

of fuel in the direction of a responsible utilization of fossil fuels.

13

Orifice fittingsOrifice metering is the most traditional and one of the most consolidated: our orifice fittings are designed to combine the reliability of the traditional devices with a degree of innovation aimed to insure performance during the time, with an easy maintenance concept.

Flow computers and metering packagesMetering gas in complex and large systems to insure at any time accurate measurement of delivered gas quantities delivered as a package. and solid particles.

Turbine meterThe natural complement of any pressure reducing and metering stations. Available with a wide range of pulse emitters and in ratings up to Class 600 for operating pressures up to 100 bar. Size range DN 50 to DN 300 mm

Beyond pressure regulator.

Gas TreatmentA range of filters, valves and accessories specifically designed for gas applications

completing the offering of products necessary to create state of the art installations

in compliance with the most demanding standards and codes.

15

Bath heatersThe indirect bath heaters have a wide variety of successful applications in the oil and gas production, processing and transmission industry. The duty of Pietro Fiorentini heaters can vary from 90kW up to 10MW.

SeparatorsThe multi-stage Filters separators provide to remove Liquids and Solids from a gas pipeline. These are installed upstream of every high pressure station whenever the gas is expected to contain a small-to-average amount of liquid impurities in form of large drops and solid particles.

FiltersTo ensure a reliable gas distribution it is necessary that all the parts of the system work at heir best. For this reason we created products integrating the more traditional pressure regulators, meters and safety devices.

Heat ExchangersThe heat exchanger is used in gas pressure regulation plants where the fluid must be preheated before decompression. It is suitable for natural gas, air, propane and other non-aggressive gases.On request the heating fluid can be hot or superheated water, or steam.
