Question regarding the selection of materials for ball tank foundation bolts
Thread Content
I recall that according to the standards for tower structures, the foundation bolts are to be made of Q235 or Q345. For spherical tanks, however, the requirements for foundation bolts are specified in GB150.2 and GB12337; these standards do not mention Q345 or Q235. So, can Q345 be used for the foundation bolts of spherical tanks? Also, how is the design temperature for the ball tank’s foundation bolts determined?
Thank you. Then how is the design temperature for the anchor bolts determined?
In GB/T1591-2018, Q345 has been removed and replaced by Q355.
1591 is the standard for structural steel, right? I see that the standard for steel plates used in containers, GB713, hasn’t been changed yet:lol
According to clause 5.2.3 of NB/T47041-2014, foundation bolts should preferably be made of Q235 in accordance with GB/T700, or Q345 in accordance with GB/T1591. In GB/T1591-2018, Q345 has been removed and replaced by Q355.
