Standard
coupon racks are available with one to six coupon holders and
have both inlet and outlet isolation ball valves. They are
available in a choice of four materials: Sch. 80 PVC, suitable
for most applications; CPVC, for applications requiring
moderately higher temperature; carbon steel and stainless
steel for high-temperature applications. The PVC and CPVC
coupon racks are mounted on a corrosion-resistant, pre-drilled
PVC panel, while carbon steel and stainless steel coupon racks
both utilize two unistrut channels. Easy to install PVC and
CPVC coupon racks feature quick disconnect, o-ring sealed
coupon holders that do not require tools for installation or
maintenance. A safety cable prevents lost coupons, while nylon
sample-holding screws do not alter coupon corrosion
rates.
