It is to reduce the loss of heat in the condenser caused by the removal of cooling water, the loss is reduced by heating the water.After the high pressure feed pump, high pressure heaters are added to increase the boiler feed water temperature and save coal resources.
ASTM A179
It is used for heat exchanger, condenser and similar heat conveying equipments
ASTM A213
It is used for boiler and super heater min wall thickness seamless steel ferrite and austenitic steel tube and heat exchanger austenitic steel tube.
ASTM A210
It is used for boiler and boiler flue tubes, including safe end, vault and supporting tube, and superheater wall thickness min or medium carbon steel tube.
JIS G3461/2
