Carbon steel tee DN80 SCH40*DN40 SCH80 NB/T47008 SH/T3408: Are the wall thicknesses different for the two sizes?
Before posting, take a screenshot of the information you need: NB/T 47008 – where are the tees in it? NB-T47008-2010 Forged products of carbon steel and alloy steel _ Baidu Wenku http://wenku.baidu.com/link?url=czkdSVMETHXbKtSXm4vv20CnPAHXNYgmzB9egoticEwT5yitw6psvqIgLyNczdd-jmKGNMzUQKIrNrofJmTVSOfFNcWzsC35bQVZTrPfObK
The material should be a forged piece of 47008; it’s originally a reducer, so it’s not strange that the wall thicknesses are different:o
NB/T47008 applies to forgings; naturally, the wall thickness varies for different diameters at the same wall thickness grade
The main pipe is DN80 SCH40 with a diameter of 5.49 mm, while the branch pipe is DN40 SCH80 with a diameter of 5.08 mm – it’s not strange that they are different. . . Made by turning forged parts. . . It’s not surprising to use material in accordance with NB/T47008,,,
It’s different; that’s normal. What was said upstairs is also correct—you can take that into consideration
The production standard is SH/T3408-2012, while the material standard is NB/T47008. The diameter of the main pipe is DN80 with a wall thickness grade of SCH40; the diameter of the branch pipes is DN40 with a wall thickness grade of SCH80. The only difference lies in the wall thickness grades of the main pipe and the branch pipes. Even when the wall thickness grades are the same, the thicknesses of the two pipes can still differ – for example, if both are SCH40, the thicknesses will be 5.49 and 3.68 respectively, which isn’t unusual
