Assessment of the pipeline, power line underground and elevated

The finished functional devices for transmission of energy and information, such as power lines, heating plants, pipelines of different function, radio relay lines, cable communication lines belong to Transfer Devices group. We estimate the following types of industrial facilities and transfer devices: A water supply system — constructions for carrying out drinking water and the technical purposes from one place (ordinary sources, the rivers and lakes) in another (city and factory rooms) mainly on underground pipes or channels; in a terminal point, often cleared of mechanical impurity in system of filters, water gathers on not kotra to height in so-called water lifting towers from where it is already distributed on city water pipes to dwellings. The amount of use of water are defined by water-measuring devices. Use the water-pressure force of a water supply system also for the hydraulic purposes. In the ancient time arranged elevated water supply systems, and water was carried out on the channels lying on arches (aqueducts). A heat conductor — the Construction for supply of hot water, couple or other heat carrier from a heating plant to consumers. Power lines — the Electric lines which are going beyond power plant or substation and intended for transfer of electric energy. Lines of a radio communication — the Antenna-feeder devices and the physical environment providing in total transfer of radio signals; compound chastkanala of a radio communication. Also sputnikovyeliniya of a radio communication are most widespread radio relay. Lines of telecommunication — the Means of communication and information transfers. The gas pipeline — the engineering construction intended for delivery of natural gas by means of the pipeline. The main gas pipelines are intended for transportation of gas on long distances. Through certain intervals on the highway the gas-compressor stations supporting pressure in the pipeline are established. In a terminal point of the main gas pipeline gas-distributing stations at which pressure goes down to the level necessary for supply of consumers are located. Gas pipelines of distributive networks are intended for delivery of gas from gas-distributing stations to the end user. The oil pipeline - the technical construction of pipeline transport intended for oil transport. Distinguish the main and trade oil pipelines.
