Shell and Tube Heat Exchangers

              Where are Shell and tube Heat Exchangers used?

Unlike conventional shell and tube heat exchangers, AMETEK products avoid scaling and fouling by using tubing made from essentially chemically inert fluoropolymers.

These unique materials have advantages overheat exchangers made with metal, graphite, or glass. Metal corrodes when it interacts with harsh chemicals, causing maintenance and reliability problems, and may lead to failure under pressure. Graphite and glass tubes may crack from thermal and mechanical shock, which may result in catastrophic failure and costly downtime.

AMETEK heat exchangers feature braided tubing bundles and unique fused ends that provide significantly better heat transfer from a smaller footprint than similar heat exchangers, allowing installation in virtually any type of tank configuration. AMETEK’s proprietary honeycomb process ensures long service life with no leaks or thermo-mechanical failures commonly found on other heat exchangers.

AMETEK is the original manufacturer of fluoropolymer heat exchangers and still the only company that makes FEP and PFA tubing for shell-and-tube heat exchangers.

shell and tube heat exchangers are used mostly in the chemical processing industry for heating, cooling, condensing, and evaporating highly corrosive liquids and gases.

 Sulfuric Acid is the chemical most used with AMETEK FPP heat exchangers.  The process of making sulfuric acid can vary, but any company dealing with the manufacturing process has a high potential for the use of a fluoropolymer heat exchanger in their process.  Other Acids commonly requiring fluoropolymer heat exchangers are Hydrochloric, Nitric, and Hydrofluoric Acids.  Another chemical manufacturing industry fluoropolymer heat exchangers are used in is the Chlor-Alkali manufacturing process.

 The Chlor-Alkali process produces chlorine as well as sodium hydroxide, ammonia hydroxide, and hydrogen peroxide through an electrolytic cell. Once the process is complete, the chlorine must be cooled and dried, and the caustic must be condensed.  Other applications ideal for fluoropolymer shell and tube heat exchangers is the manufacturing of bromine, an electronic chemical market which produces ultra-high purity acids for the SEMI conductor industry, and the Lead Acid Battery industry which uses sulfuric acid in the manufacture of battery paste.
