Main brand or steel grade of American standard high-pressure boiler tubes Commonly used brands are: SA-179M, SA-192M, SA-209M T1a, SA-210M Gr.C, SA-210M Gr.A1, sa-213th mt11, sa-213th mt12, sa-213th mt23, sa. executive standard Seamless cold-drawn low carbon steel tubes for SA-179/SA-179M heat exchangers and condensers. Seamless carbon steel boiler tubes for SA-192/SA-192M high pressure. Seamless carbon-molybdenum alloy steel pipe for SA-209/SA-209M boiler and superheater. Seamless medium carbon steel tubes for SA-210/SA-210M boilers and superheaters. Seamless ferritic and austenitic alloy steel tubes for SA-213/SA-213M boilers, superheaters and heat exchangers. Product features When high-pressure boiler tubes are used, they will be oxidized and corroded under the action of high-temperature flue gas and steam, which are often under high temperature and high pressure conditions. Therefore, the high-pressure boiler steel pipe has high strength, high reaction corrosion resistance and good-good organizational stability. Gauge group distance The outer diameter is ∮15.88~89mm, and the wall thickness is 2.6 ~ 12.5 mm.
