A physical plant , mechanical plant or industrial plant (and where context is given, often just plant ) refers to the necessary infrastructure used in operation and maintenance of a given facility. The operation of these facilities, or the department of an organization which does so, is called "plant operations" or facility management . Industrial plant should not be confused with "manufacturing plant" in the sense of "a factory ". This is a holistic look at the architecture, design, equipment, and other peripheral systems linked with a plant required to operate or maintain it.
37-648: Danieli Group ( Italian pronunciation: [danˈjɛːli] ) is an Italian supplier of equipment and physical plants to the metal industry . The company is based in Buttrio , in the north-east of Italy ( Friuli-Venezia Giulia region). It is one of the world leaders in the production of steel plants, in particular in the long products segment, where it owned more than 60% market share in 2000. It has more than 25 divisions worldwide (design, manufacturing and service centers), 7 of which are production centers ( Italy , Russia , Austria , Brazil , Netherlands , Sweden ,
74-442: A building when the coverage is poor. They will usually be placed on a roof or a wall in each building. Desalination plants are responsible for removing salt from water sources so that it becomes usable for human consumption. Reverse osmosis , multi-stage flash and multi-effect distillation , are three main types of equipment and processes used that differentiate desalination plants. Thermal technologies such as MSF and MED are
111-724: A key component of mobile telecommunications infrastructure. They connect the end user to the main network. They have physical barriers protecting transition equipment and are placed on masts or on the roofs/sides of buildings. Where it is located is determined by the local radio frequency coverage that is required. These base stations utilize different kinds of antennas, either on buildings or on landscapes, to transmit signals back and forth Directional antennas are used to direct signals in different direction, whereas line-of-sight radio-communication antennas, allow for communication in-between base stations. Base stations are of three types: macro-, micro- and pico-cell sub-stations. Macro cells are
148-500: A large network of equipment to retrieve, store and transfer water to a plant for treatment. Water from underground water sources are typically extracted via wells to be transported to a plant. Typical well equipment includes pipes, pumps, and shelters. If this underground water source is distant from the treatment plant, then aqueducts are commonly used to transport it. Many transport equipment, such as aqueducts, pipes , and tunnels utilize open-channel flow to ensure delivery of
185-422: A mixing tank. Variable-speed paddle mixers are used to identify the best mix of salts to use for a specific body of water being treated. Flocculation basins use temperature to condense unsafe particles together. Setting tanks are then used to perform sedimentation , which removes certain solids using gravity so that they accumulate at the bottom of the tank. Rectangular and center feed basins are used to remove
222-567: A water abstraction and pre-treatment equipment, although in MSF different chemicals such as anti-sealant and anti-corrosives are added. Heating equipment is used at different stages at different pressure levels until it reaches a brine heater. The brine heater is what provides steam at these different stages to change the boiling point of the water. Conventional water treatment plants are used to extract, purify and then distribute water from already drinkable bodies of water. Water treatment plants require

These stakeholders have active responsibility for these processes and equipment. The manufacturer's primary responsibility
703-542: The family had a different point of view. Eventually, 58% of the ordinary shares were sold to SIND (Società Impianti Industriali), held 50% by Cecilia Danieli and 50% by Gianpietro Benedetti. Following the new corporate structure, the expansion around the world continued. In 1987 Danieli acquired Morgårdshammar, a Swedish group specializing in rolling plants for special steels, and later Wean United (USA), Rotelec (France) and Sund (Sweden). The results seemed to justify that generational change wanted by Cecilia: Danieli’s turnover
740-627: The first direct rolling plant for quality steel in the USA. In the mid-eighties, the steel industry again encountered difficulties. A different strategy emerged within the Danieli family in order to remain competitive: Cecilia, who held a degree in Economics and Business from the University of Trieste (Italy), and Gianpietro Benedetti were in favor of a major restructuring, in line with a strategy of internationalization and expansion of products. The rest of
