This is a document on Baseline Inspection
The Importance of Baseline Inspections
Baseline inspections are commonly used for code compliance verification, however, they also provide excellent opportunities to initiate a corrosion monitoring database.
Therefore, it is important to have accurate baseline data and the effect it can have on prediction accuracy and integrity resource allocation.
Prediction of inspection, maintenance and repair activities require detailed knowledge on deterioration rates. Common practice can include using nominal wall thickness as a replacement for accurate baseline measurements. However, large variations (i.e. mill tolerance) can occur, resulting in inaccurate deterioration rates, incorrect scheduling of activities and significant increased life cycle cost.

tolerância de variação de espessura
Essa tolerância varia de acordo com a as especificações do material em questão.
"...Mill tolerance comes from the manufacturing process of seamless pipe. Welded pipes have a tolerance as well, but usually is not a mill tolerance and it is much lower because it’s more easy to get high accurancy when producing steel plates. On the other hand welded pipes need to consider the weld joint efficiency factor, to take in account the weakness in the welding."
"...Values of mill tolerance are defined in the material standards. For example paragraph 16-3 of ASTM A 106 states “the mimimum wall thickness at any point shall be not more than 12.5% under the nominal wall thickness specified”."

Discussion
Eu ficaria com tolerância ao processamento em moinho. Lembrando que tolerância requer a preposição "a" e não "de". Tolerância "de" seria a tolerância do material e não ao processo.
