Maintenance and Inspection of Tank Vent Devices
Maintenance and Inspection of Tank Vent Devices
(OP)
Low pressure API tanks seldom have installed spare vent devices (PVRV, ERV, VRV, etc). How does your company handle maintenance and inspections of these devices when there isn't an installed spare? Do you do all of this testing/inspection in-situ, without removing the device to the shop? Do you remove the device and install a temporary shelter over the open tank nozzle while the device is in the shop? Does your company have a standard maintenance procedure for safely protecting the tank while these devices are removed for inspection?
Thanks
Thanks

Are you installing a temporary goose-neck on the nozzle while the vent device is in the shop? Do you keep a shelf-spare, and install it when the tank device is removed? Do you just leave the nozzle open until the vent device is ready to be re-installed?
Thanks.
