GB 3087 Grade 10 Seamless Boiler Tubes
Standard:GB 3087
GB 3087--Seamless steel tube for low and medium pressure boilers
GB 3087 standard is applicable to the manufacture of high-quality carbon structural steel hot-rolled (extruded, expanded) and cold drawn (rolled) seamless steel tubes for various structural low-pressure and medium-pressure boilers and locomotive boilers.
working condition
GB 3087 grade 10 seamless steel pipe is mainly used for manufacturing heating surface of industrial boiler, with working pressure ≤ 5.9mpa
When GB 3087 grade 10 is used as heating surface pipe, the maximum wall temperature ≤ 480 ℃, and when GB 3087 grade 10 is used as header and steam pipe, the maximum wall temperature ≤ 430 ℃.
