Stephen H on Tank Bottom repairs - Corrosion left unrepaired

By: Stephen H 
Date: Tuesday, March 01, 2005
Time: 12:00:00 AM

First, is there anything that requires the tank maintenance to meet API-653? This would vary by locality. Secondly, do the 0.21" pits meet API-653? That leaves 0.10" of metal, which I suppose is adequate to hold the contents, but I don't have API-653 here at the house to look it up. I'd say if they planned to use the tanks for any length of time, they should repair those places, regardless, but that's largely a financial consideration if the standard doesn't require it. On the Charpy requirements, that would depend on the circumstances. If the tanks were built to older API-650, or to current Appendix A, they may not meet current charpy test/exemption requirements, but I don't think there's anything that requires that they should. You don't have to go back and rebuild every old tank whenever they update a standard. If the tanks are heated, or insulated, or if product coming in is heated, etc., the original builders may have deduced that the design metal temperature could be higher than shown in API-650. Or local experience may have so indicated. You could also be assuming steel was A36, when it actually met the requirements of A36-mod, or the material could have been normalized without that showing in your records, as well. Or, they may have had charpy impact tests or records for the plate, and that information is no longer available (can be based on mill records of similar material, as I recall). Or the material could be a dual-spec material (IE, A516-70 that also met A516-60).

Honeycomb Panel IFR
By: davidr@fast.net [39]

Honeycomb panels used on internal floating roofs are a sandwich construction consisting of an upper and lower skin with core in between. The materials are most often aluminum. In this scenario, the core is usually 0.003 thick aluminum foil expanded to a six sided shape similar to what bees make in their hives, hence the name honeycomb. The top and bottom skins are 0.16 minimum, sometimes as thick as 0.040. The core may be of solid aluminum foil or it may have perforations. The perforations ....   Read All
