25Heat exchangersMain constructional materials are carbon steel, stainless steel,brass, titanium and their combinations.Basic characteristics24Heat exchangersThe main product lines used in the production:ТU 3612-023-00220302-01ТU 3612-024-00220302-02ТU 3612-007-00220302-99ТU 3612-013-00220302-99ТU 26-02-753-83SТО 00220256-003-2006––––––Heat exchange processes are of great importance for chemical,power, metallurgical, food industry and other branches. Heatexchange processes are carried out in the heat exchangers ofdifferent types and configurations. All variety of heat exchangeequipment is intended for heating, cooling, evaporation andcondensation of liquid, gas, steam and their mixtures in thecourse of technological processes in chemical, oil, petrochemical,gas industry and other branches. It can be also used for waterheating in hot water supply and heating systems of residential,public and industrial buildings.ApplicationModern chemical industry widely uses different aggressivemediums, e.g. alkalis, salts with different concentrations, organiccompounds and gaseous mediums. In the course of production,these mediums shall be stored, transported, exposed to heat andpressure. Chemical fusion reactions, end products manufacturetc. are accompanied by release of heat and by-products, which areoften more aggressive than raw products etc.Action of aggressive mediums, especially at high temperature andpressure, leads to considerable corrosion of equipment made oftraditional materials.Along with increase of the product cost due to constantrenewal of equipment, repairs and assembly work, thereis a danger of environmental contamination for thewhole regions and decline in population health.One of the materials with high corrosion resistance istitanium and its alloys. The main consumer in chemicaland petrochemical industry is chlorine industry. Thebasic type of equipment made of titanium is heatexchange and evaporation devices. Corrosion resistanceand low adhesion (inadhesion) of organic substancesand salts to the pipe surface make it possible to increasethe repair intervals, extend considerably the lifetime,maintain the high thermal characteristics throughoutthe service life, reduce repair costs and equipmentdowntime. The enterprise has developed themanufacture of heat exchangers made of titanium.
2726Heat exchangersSectional heat exchangersThese heat exchangers consist of the series section elements.Combination of several elements with a few pipes correspondswith the principle of operation of multiple-turn shell-and-tubeheat exchanger, which works on the basis of more efficientcountercurrent flow system.Main groupsShell and tube heat exchangersShell and tube heat exchangers can be vertical, horizontal and inclined according torequirements of operating procedure and assembly efficiency. The main components ofshell and tube heat exchangers are tube bundles, tube sheets, body, lids and branchpipes. Pipe ends are fastened in the tube sheets by expansion, welding and soldering.The heat exchangers, chillers, evaporators and condensers are manufactured:Spiral heat exchangersHeat surface of spiral heat exchangers consists of two thin metal sheets, which arewelded to the baffle (core) and coiled. Rectangular-section spiral channels are closedwith end plates. Spiral heat exchangers are compact, have low flow resistance and highheat exchange rate under high rate of heat carriers.18.104.22.168. With the air-floating head (“P” type) and U-shaped pipes(“U” type).With the fixed tube sheets (“N” type), they can also have a compensatoron the casing.Thermosyphon evaporators.Vacuum condensers.STO 00220256-003-2006The main production line:Double-pipe heat exchangers of “pipe-in-pipe” typeHeat exchangers of this type consist of a number of components connected in series.Each component consists of two coaxial tubes. Inner tubes are usually connectedtogether by the “kalatchs” or u-bends to ease cleaning and replacement. Double typeheat exchangers with big heat surface consist of sections, connected parallel by thecollectors. The selection of diameters of inner and outer pipes can provide the requiredrate of both working mediums, which take part in the heat exchange, necessary forachievement of high heat exchange intensity. Advantages of double-pipe heatexchanger are high heat emission, suitability for heating and cooling of workingmediums under high pressure, ease of production, installation and maintenance.moving with commensurable speed without change of aggregatestate. They can be effectively used at the high pressure of workingmediums. Lack of baffles reduces the hydraulic resistance andlevel of shell side contamination. But in comparison withmultiple-turn shell-and-tube heat exchangers, the sectional heatexchangers are less compact and more expensive due to the largequantity of expensive elements, tube sheets, flange couplings,compensators etc. Heat exchange surface of one section ofelemental heat exchangers comes up to 0.7530 м2, the numberof tubes is 4 to 140.Sectional heat exchangers are effective, when the heat carriers areFinned heat exchangersFinned heat exchangers are designed to extend heat exchangesurface by finning on the side, which has the highest thermalresistance. For example, finned heat exchangers (radiators) canbe used during steam heating of air or gases. The importantcondition of effective use of fins is the tight contact with the basicpipe (lack of air gap) and rational fins distribution. Finned heatexchangers are widely used in drier installations, heating systemsand as economizers.Coil heat exchangersHeat surface of coil heat exchangers composes of a number ofconcentric coils, which are jacketed and fastened in thecorresponding heads. Heat carriers are moving in the tube andshell side. Coil heat exchangers find wide application in highpressure equipment for separation of gas mixtures by deepchilling. These heat exchangers have a self-compensation ability,which is sufficient for perception of deformations due to thetemperature stresses.–Equipment for boiler houses and heat supply stationswater heatersteam-water heater for heating systemsboiler–––
