ASME SA516/ASTM A516 GR.70N Tubesheet Heat Exchanger,ASME SA516 Grade 70N tube sheet
We are professional ASTM A516 Gr.70 Grade 70 tube sheets / Baffles plates/ tube Support Plates manufacturer and exporter in china.
Tubesheets are one of the most important components of Shell and Tube Heat Exchangers. tube sheets are usually made from a round flat piece of forged plate which are machined with holes drilled for the tube ends in a precise location and pattern relative to one another. Tube holes can be drilled and reamed and can be machined with one or more grooves that greatly increases the strength of the tube joint. Fabrication Our workshops have been equipped with modern machineries including CNC drilling machines in order to make any kind of tube sheets. tube sheets are widely used for fabrication of heat exchangers in any configuration. All machining activities such as lathe machining, drilling, reaming, taping, grooving, and surface milling can be carried out exactly according to client’s drawings and specifications. As all of drilling activities is programmed computer and done by state of art CNC machineries, there would not be any possible mistake caused by human
