For highly corrosive environments in chemical manufacturing, we recommend titanium or nickel alloy calandria bundles. Titanium offers excellent resistance to chlorides and oxidizing acids, while nickel alloys like Hastelloy perform well in reducing acids and alkaline solutions. Duplex stainless steel provides a cost-effective option for moderate corrosion resistance.
Baffle plates in calandria bundles direct shell-side fluid flow across tubes, increasing turbulence and heat transfer efficiency by up to 40%. They also provide structural support to prevent tube vibration and damage. Proper baffle spacing and design minimize pressure drop while maximizing thermal performance in evaporation applications.
Regular inspection for fouling, corrosion, and tube integrity is crucial. Chemical cleaning protocols should match your specific process fluids. Monitor for tube sheet leaks and ensure proper vacuum sealing. Consider retubing options when corrosion exceeds 20% of tube wall thickness. Proper material selection during initial design significantly extends service life.
