Sa213 T11 Precision Steel Tube Cold Drawn Seamless Heat Exchanger Boiler

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.
