Materials of construction glass

Materials of Construction. Glass has excellent corrosion-resistance to wet or dry bromine. Lead is very usefiil for bromine service if water is less than 70 ppm. The bromine corrosion rate increases with concentrations of water and organics. Tantalum and niobium have excellent corrosion-resistance to wet or dry bromine. Nickel has usefiil resistance for dry bromine but is rapidly attacked by wet bromine. The fluoropolymers Kynar, Halar, and Teflon are highly resistant to bromine but are somewhat permeable. The rate depends on temperature, pressure, and stmcture (density) of fluoropolymer (63). 

The reactor contribution depends on the reactor size and material of construction. Glass-lined reactors are about 40-50 % more costly than the stainless steel reactors. The total investment costs also depend upon the equipment size, as illustrated by Fig. 7.3-1. 

Materials of Construction. Glass and silica are of general application, but metals should be used wherever possible in routine and long-term test apparatus because of their high strength and heat conductivity. At low...
