We are professional AISI 304 TP304 SS304 SS 304 304SS 304 SS UNS S30400 1.4301 stainless steel tube bundles Tubing Bundles For shell tube Heat exchanger Boiler condensors heaters coolers evaporators 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.

Grade 304 stainless steel is the most versatile and the most widely used of all stainless steels. Its chemical composition, mechanical properties, weldability and ncorrosion/oxidation resistance provide the best all-round performance stainless steel at relatively low cost. It also has excellent low temperature properties and responds well to hardening by cold working. If intergranular corrosion in the heat affected zone may occur, it is suggested that CS 304L be used.

Typical Applications

CS 304 is used in all industrial, commercial and domestic fields because of its good corrosion and heat resisting properties. Some applications include:

  • Tanks and containers for a large variety of liquids and solids.
  • Process equipment in the mining, chemical, cryogenic, food, dairy and pharmaceutical industries.
