We are professional Hastelloy Alloy B-2 B2 UNS N10665 2.4617 NiMo28 nickel alloy tube bundles Tubing Bundles For shell tube Heat exchanger Boiler condensors heaters coolers evaporators Factory from china
tube bundle heat exchanger with baffles is disclosed wherein a tube bundle is housed within an inner casing which is acted upon from both the inside and the outside by a heating medium
A multiple tube bundle heat exchanger includes axially opposite tube plates, a housing, and a plurality of tube bundles disposed between the tube plates. Each of the tube bundles is an independent tube bundle subassembly forming an integral unit having at least one heat exchanger tube with two axial tube ends.
