Thank you both.

Is there really no punctuation in the first paragraph apart from the comma after "Buen dia" and the full stop at the end?
Do you have any more information about what they are talking about? Do you know anything about the "inconveniente"?
Are you sure that "tubos de mezcla" means "mixing tubes", or could it mean "tubes of mixture" (i.e., tubes full of some sort of mixture). Could the "mixture" be some sort of product used during cutting operations, e.g., a lubricant or coolant?
Trying to work out the structure of this paragraph, it seems possible to me that there should be a full stop after "mostrar y revisar", so the next bit is a new sentence: "Su duration en corte de inoxidable es muchísimo menor......".

I mean, not clear enough the original. Seems that the writer and the receiver speak their own language, plus that this is Latam... which makes it more difficult at first sight for a Spaniard. Let´s see: "tubos de mezcla" may mean the "assortment" of pipes or "the pipes for mixing". As for "corte de inoxidable", while inoxidable means, unambiguously, "stainless", unless he means that the pipes were (earlier) carbon steel, that, for corrosion reasons, they were changed by stainless steel and now it seems that the stainless does not meet the strains in the installation (first thing I have thought, stainless is much softer, or not as hard, than others, and cannot be tempered), so he might mean that the "tubos", changed to stainless, seem to last less (plus most probably are more expensive than), and are not profitable.

But this is all guesswork.
