On-site reaming of the boiler steel frame and spring constant-force hangers.
Thread Content
At the installation site of the boiler steel frame and spring constant-force hangers, the steel frame has elliptical holes as designed; due to issues with the elevation marks during installation, these holes were enlarged. Is it now necessary to calculate the strength of the steel frame?
If the holes are enlarged, it definitely needs to be calculated, as the strength of the beam will decrease.
It’s not just a matter of calculating intensity here; look at the cutting quality of the reaming – it’s jagged like teeth. How can such quality be acceptable?
