ASTM A182 F316L / UNS S31603 / 1.4404 Stainless Steel Tubesheet for Heat Exchanger
YUHONG GROUP is experienced on the supplying the tubesheet, baffles, body flange and other heat exchanger parts to more than 55 countries and got very good reputation in the market. If you have such demands, please feel free to send us inquiry.
Tubesheet of Heat Exchanger
Tubesheets are usually made from a round flat piece of metal with holes drilled for the tube ends in a precise location and pattern relative to one another. Tubesheet materials range as tube materials. Tubes are attached to the tube sheet by pneumatic or hydraulic pressure or by roller expansion. Tube holes can be drilled and reamed and can be machined with one or more grooves. This greatly increases the strength of the tube joint. is in contact with both fluids and so must have corrosion resistance allowances and have metalurgical and electrochemical properties appropriate for the fluids and velocities. Low carbon steel tube sheets can include a layer of a higher alloy metal bonded to the surface to provide more effective corrosion resistance without the expense of using the solid alloy.

One of the most common heat exchangers in service within industrial
process applications is the “Shell & Tube Heat Exchanger”.
They are available in many shapes, sizes and have been used in
industry for over 150 years. In this exchanger group are various
sub design types: Fixed, U-tube and Floating tubesheet. Variations
of all can be denoted as type “E”, “F”, “G”, “H”, “J”, “K” or “X”.
The main applications are where high pressure/temperatures are key
considerations. Loosely, general designs consist of the or an
outer shell in which resides a tube bundle (these can be configured
as finned, plain etc) sealed at each end by a tube sheet which
isolates the tubes and the outer shell.
Shell & tube heat exchangers have the capability to transfer large amounts of heat at low(er) costs. This, in principle, down to both
design simplicity and effectiveness – large tube surface for reduced weight, volume of liquid and importantly floor space.
Application
Water works, Shipbuilding industry, Petrochemical & Gas industry, Power industry, Valve industry and general pipes connecting projects etc.
