SA213 T11 Cold Drawn Seamless Heat Exchanger Boiler Tube
Production Method:
Carbon Steel Seamless Heat Exchanger Boiler Tubeis a kind of boiler pipe, which belongs
to the category of seamless steel pipe. The
manufacturing method is the same as that of seamless pipe, but there are strict requirements
for the steel Grade
used in the manufacture of steel pipe. pressure cooker
Furnace seamless tubes are often in high temperature and high pressure conditions when
used. The tubes will ndergo oxidation and corrosion under the action of high temperature
flue gas and steam. The steel pipe is required to have high lasting strength, high anti-oxidation
and corrosion performance and good structural stability. High pressure
boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, air ducts,
main steam tubes, etc.of high-pressure and ultra-high-pressure boilers.
