Welding Coal Fired Boiler Tubes Sa 213 T

Home - Tranter

Heat transfer through plates instead of tubes offers many advantages. Turbulent flow at low velocity produces high heat transfer efficiency and low fouling. You save boiler fuel. Maintenance burdens are reduced. Weight and footprint are smaller. Frequency of corrosion and leaks pale in comparison.

Description of Boiler Tube Grades - Chicago Tube & Iron

BOILER TUBE GRADES CARBON STEEL SA178 Carbon steels show mild corrosion resistance and fair strength up to 1000F. However, their usage above 800F must take into account the susceptibility to graphitization. Graphitization has not been a significant problem in thicknesses encountered in boiler tubing. Use of heavy section pipe above 800F, however, is not recommended. []

SA-213-T14 tube material - Boiler and Pressure Vessel

The only designation that would come close to a 2% Cr tube that you describe is Croloy 2 (this is from one of my old B&W Tube material source books). There was no SA 213 Grade designation in the chart for the Croloy 2 at the time the tube material chart was printed. Anyway, this material should be under a P-No 5 A designation for welding.
