Heat exchangers are intended for hearing (cooling) of high pressure gas or condensate by other heat exchanger. The last can be diethylene glycol (DEG) or natural gas
A number of heat exchangers with the surface of heat exchange from 1 to 50 m3, with flows of condensate or gas from 0,15 106 to 0,5 106 mm3/24 h and pressures from 1.7 to 16.0 ÌPà was developed.
Pipes used in the developed structures: for casing – with external diameters from 60 to 168 mm, for internal pipes – with external diameters from 10 to 34mm.
The structure of heat exchanger includes a few series-connected sections, each is made by external heavy-wall pipe and a few internal pipes, fixed in pipe boards by electric welding. Movement of heat carriers is opposite-flow.
Transportation of heat exchanger may be by rail, motor and water transport.
Apply international standards ANSI, API, ASME, DIN, ISO, GOST, DSTU.
