One of our sub supplier have performed a rubber lining inside two our vessels. The thickness in some points was 3.3 mm instead of the required 4 mm (tollerance +/- 10%). Our client's inspector rejected the vessels and we have proposed to add an additional layer of 2 mm of rubber lining. Our...
I have a skid with PVC reinforced with GRP piping. This skid will work at ambient temperature above 0°C but can be stored (before working) in an area where the minimum temperatrue could be -33°C.
I know that the materil will became very fragile at -33°C but what I would like to know is if this...

Do pyrolusite reduce...
