Okay, this is putting things to the extreme. But this is just to bring about the case in point. Should you still be a habitual and traditional pipe smoker, your pipe will in all probability be lined with a bit of rubber in strategic areas of the pipe. This is to preserve the integrity of the pipe in response to its prolonged use. It is also there to protect you. No matter how pure your materials may seem, harmful toxins still have a nasty habit of intoxicating you. That is to say that you let it. On the highest scale of industry just think what one rubber lined pipe achieves for the industry in question.
On the highest scale of industry, all forms of piping are certainly put through its paces. It is extensively used. So much wear and tear will inevitably occur but there is no shortage of developmental skills and expertise that informs necessary repair and maintenance work. But even so, it remains an expensive exercise, particularly on the highest scale of industry. Big firms out there will always be saving a buck in utilizing the most efficient piping structures, most of which will be lined protectively with rubber.
And if it is not lined, it will be due to the specific purpose for which the affected pipe serves. If large multinationals can make gigantic savings in their industries, then so can you. You are perhaps operating on a much smaller scale than them so the work that needs to be prepared and done for you will be more than manageable. It is, in any case, being carried out by skilled entrepreneurs, skilled and expert at what they do, just like you are in your business.
