Anna Veronesi — Thu, 20 Jun 2024 12:05:21 +0000

LDB171 is a new silencer option for Reflux/Reval regulators. The silencer LDB171 allows reducing the noise that is generated in the pressure regulator during the lamination process. Its efficiency is due to the fact that noise reduction takes place at the same point where it is generated, thus preventing its propagation.

It can be used with the following regulators:

Modularization

Digital Team — Thu, 04 Mar 2021 11:46:24 +0000

Oil and Gas plants are complex entities. Handling all the aspects involved in treatment, processing, regulation and measurement of fossil fuels is a matter of knowledge that spans through dozens of different fields. Chemical, mechanical, electronic and electrical engineering are just some of the subjects involved in these massive projects.
The Human Resources Department of Pietro Fiorentini has gathered all the required professionals that cover these topics, and thanks to both decades of experience and adaptive management frameworks they can find a solution for the most demanding undertaking.
Modularization is considered the key factor for the successful implementation of those projects where the significant reduction of the site construction period is required or where the remote location does not allow to easily hire qualified personnel on-site. Modularization works are executed in a yard conveniently located nearby a harbour to ease transportation activities. The modules are usually supplied complete of steel structures, equipment, piping, instrumentation, electrical tracing, lighting and grounding materials, thermal insulation and painting. Cabling and cable trays are included within module’s battery limits. Hydraulic test and pre-commissioning activities will also be carried out at shop before modules delivery.

Front end engineering design

Digital Team — Thu, 04 Mar 2021 11:44:20 +0000

Front end engineering design (FEED) is an engineering design framework used for an in-depth check of a project cost. The main target of this approach is to analyse project requirements, fix a design basis, freeze the process design and involve all main subvendors. At the end of this execise the FEED provides a detailed cost summary, that will allow contractors and suppliers to issue a firm quotation.
FEED process is handled by Pietro Fiorentini multidisciplinary team that takes into consideration all important aspects related to the project. Main objectives include definition of civil, mechanical and process engineering, carry out preliminary HAZOP & SIL, prepare main equipment list and data sheet of critical items, develop 2D & 3D preliminary models and finally automation strategy.
The main scope of FEED is to deliver a clear picture of all project constraints, i.e. technical aspects, safety & environmental issues and accordingly a deep evaluation of capital and operation costs.

High pressure stations

Digital Team — Thu, 04 Mar 2021 11:29:00 +0000

Natural gas is usually highly pressurized as it flows through transmission pipelines, but once it reaches the consumers, it needs to be brought up to the contractual specifications for delivery. This often means that in high pressure stations solids and liquids have to be filtered out, the pressure has to be reduced, and the gas may need to be preheated to compensate the cooling effect of the pressure reduction (Joule-Thomson effect). Moreover, the downstream consumers need to be protected for over-pressurization from the transmission line.
An accurate pressure control is the main contributor to the smooth flow of gas into transmission lines. The wide range of models allows to choose always the most suitable product for each application, because 80 years of experience in the field tell us that not all applications have the same maintenance and silent operations.

Gas metering

Digital Team — Thu, 04 Mar 2021 11:26:20 +0000

Gas metering stations are located along gas distribution and transmission networks. These stations allow pipeline operators and local distribution companies to monitor, manage, and account for the natural gas flowing through the network.
The main scope of a gas metering station is to measure the flow of gas, allowing distribution companies to manage the network and gas sellers to allocate and bill the consumption.
The flow rate through a station can be measured by means of different devices such as rotary, turbine and ultrasonic meters and orifice fittings. They record the flow rate in actual cubic meters and a volume converter calculates the equivalent compendated for pressure, temperature and density.

HIPPS

Digital Team — Thu, 04 Mar 2021 11:16:34 +0000

High Integrity Pressure Protection Systems (HIPPS) by Pietro Fiorentini are mechanical and electrical solutions designed in order to reduce the chance that the pressure will exceed the tolerable allowable level.
These systems are used in the Oil & Gas industries to provide pressure protection of pipelines, piping, vessels and process packages against over pressure, allowing the use of lower design pressure downstream.
Compared to conventional overpressure protection design standards that are based on relief devices (relief valves and rupture disks) that discharge to atmosphere, HIPPS has the great advantage to allow lower pressure rating downstream and to avoid discharge of natural gas to atmosphere.
