well not really, oil is a different business, what matters to petrobras is getting that oil out of the ground for as little cost as possible, it's not as if they can undercut somebody by using better insulation for their pipelines. Oil will still be sold for 80 dollars regardless.
basically it is a competitive advantage, but it won't really shift their sales or take sales away from other oil companies.
while with coats, if they can lower their production costs by a couple percentage points they probably would have a good advantage over other textile companies and could sell more for the same margins or get even fatter margins. textiles just seems like it would be more cut throat to me since there are so many textile companies and it's relatively easy to start one.
