Our Client is requesting hardness testing as mentioned in the equipment welding specification, where it stated the hardness test to be carried out on the following area for equipment which include tanks: 1. On Circumferential seam (some percentage) 2. Longitude seam (some percentage) 3. All temporary weld made and remove (100%) All the above requirements are so impractical to us since we are fabricating/erecting atmospheric tank (large diameters too). The amount of temporary weld (for erection purpose) are tremendous i.e. thousands for each crude oil storage tanks and hundreds on the miscellaneous tanks. The hardness test was carried out during the qualification of Welding Procedure Qualification and it meets the hardness value requirement. And there are no requirements for hardness tests as per API 650. I believe that it is meant for pressure vessel tanks only, but OWNER insists on the test since it is stated in the specification. Any comment on this client requirement? Please help.

Noel
