347H Stainless Steel Tubes

Guanyu Tube is specialized manufacturer of ASTM A213 SA213 304H S30432 (Super 304H) 321H 347H 309S 310S 316H S31035 800HT N08811 N08825 Boiler Tubes. Boiler Tubes include Reheater Tubes and Superheater Tubes, are those tubes, which have the capacity of handling with high pressure and temperature. Stainless steel is used in reheater and superheater sections of boilers, either under supercritical steam con-ditions, or in highly corrosive envi-ronments. The more efficiency is re-quested, the more challenging is the environment for the steel.

High Pressure Stainless Steel Reheater Tubes and Superheater Tubes for Boiler, selected prime raw material,cold drawn, cleaning and smooth surface on OD/ID,Withstand high pressure,no deformation after cold bending, no crack and break after flattening and flaring etc.

Heat resistant austenitic steel have good creep rupture strength between 500-680°C which make them excellent for their use in the new genera- tion thermal plants operating under supercritical conditions above 550°C and 24.1MPa.
