    B7 versus B16 bolts

    jt, Thanks for the information. I will review that specification you mentioned and see how it benefits us. Our ducting serves as an exhaust system for large ground power turbines. The temperature of the bolts was estimated from FEA models that have been performed on our expansion joints...

    B7 versus B16 bolts

    We are using B16 bolts for expansion joints in large exhaust ducts that have hot flanges. The temperature ranges from 800 F to 1000 F with an internal duct failure pressure of 20 inches of water. What is the advantage in using B16 bolts in place of B7 bolts? The B16 bolts are 10X the price of...
