Description:

"India Pharma Company needs FDA GMP Building and Construction Consultant to guide with the following:
1) what material coating should be done over the Stainless Steel (SS)-316 equipments (switchboards, external portion of reactors etc) to avoid rust coloured pitting marks formed over these materials...

2) We have a Rotomac Vaccuum Drier (RVD) made of SS-316, that moves hot water (80 - 90 degreec C & 720 to 760 mm/Hg vacuum application) within its outer jacket. Wet cake of Glucosamine HCL is kept inside the RVD alongwith 5% Ethanol to dry. Vapour temperature inside RVD=upto 60 degreec C. Ph=1. The RVD internal tefflon coating has peeled off in 1 year. Would internal coating for RVD as Polystyrene be successful instead of Tefflon as Polystyrene is far more economical ??"
