ASTM A179 Cold Drawn Heat Exchanger Tubes
Advantages of tubular heat exchanger:
fast heat exchange, high temperature resistance (400 ℃) and high pressure resistance
(2.5MPa). Compact structure, small floor area, light weight, convenient installation and
saving civil engineering investment. It has flexible design, complete specifications, strong
practicability and pertinence, and saves money. Wide application conditions, suitable for
large pressure, temperature range and heat exchange of a variety of media.
manufacture:
Tubes are manufactured by seamless process and both hot finished and cold finished are
applicable Hot finished tubes need not be heat treated.
Heat treatment:
Cold Finished tubes are heat treated after the final cold finishing pass at a temperature
of 1200℉(650℃) or higher
