3 Sept 14: Applications in Use, II--PVC and CPVC Piping

We found a report, admittedly a bit dated, on the use of PVC (and CPVC) not only as piping components, but also in other applications.  One of the striking bits of information is found on page 9 of this report: "PVC has captured an 80% share of the buried pressure water pipe market in diameters greater than 100 millimeters."  It is worth reading the entire report, especially if you are still using steel or stainless steel pipe in applications where CPVC or PVC has proven itself.

If one goes back to the late 1950s, early 1960s, automobiles and paper machines were made of nearly the same thing: lots of steel

However, starting in the late 1960s, early 1970s, these paths diverged.  Automobiles went to plastics and other materials, such as aluminum.  Paper machines stayed with steel, but moved to a larger percentage of stainless steel. Check out the latest LGMI Weekly.See More

So, why not paperboard for dryer hood skins?

It always struck me (Jim Thompson) that machine tools are made of steel, yet machine tools are used to shape steel.  Hence, if we are making paper, what parts of our machine can be made of the product it produces? Dryer hoods come to mind. Check out the latest LGMI Weekly.See More
