We need to anchor a frame to concrete base in a facility that produces steam. The anchors are under the steam header, which operates constantly at 550 degrees F. So, the anchors are going to be very hot for a very long time. Which anchor type do you recommend for this application? Obviously, epoxy anchors are out. Also, I see there is a POM sleeve on the HSL anchor, so I assume those won't work. Would Kwik Bolt TZ2 Stainless Steel be OK in this application? We need large diameter and deep embedment to get the loads to work.
Hi Joseph,
When it comes to high temperature and mechanical anchors, it is important to evaluate the material properties of the steel. In general, stainless steel can withstand pretty high temperatures before deformation. However, since there is steam and moisture involved there are additional concerns such as corrosion. There is no acceptance criteria or test standards related to temperature for mechanical anchors per ACI 318. Ultimately, it will be up to the EOR to evaluate and make a decision.
