We are professional AISI 321H TP321H SS 321H 321 H SS UNS S32109 1.4940 TP 321H SUS 321H stainless steel tube bundles Tubing Bundles For shell tube Heat exchanger Boiler condensors heaters coolers evaporator from china
A 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.
