Is coating/ lubricating heat exchanger internal bolts advisable?
(OP)
Under what conditions Shell and Tube heat exchanger internal bolts found in floating head flange, baffle plates, tie rods need not be lubricated or coated? I understand the process fluid generally washes out the coatings on the fasteners. In that case, the available clamp force on the fasteners would change while in service. Is it a practice to identify the compatibility compound or coating for fasteners for that service and operating conditions? TEMA and API are silent on such matters.
