— Tubesheets Fabrication
Tubesheets are one of the most important components of Shell and Tube Heat Exchangers. These parts are usually made from a round flat piece of forged materials 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. These parts 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.
Heat Exchanger Tube Sheet
— Size and Shape
Any size and shape of tube sheet used to make a TEMA or even non-TEMA type can be provided. Our drilling facilities which are equipped with deep drilling mechanism are able to drill very thick plates straightly without deviation from acceptable tolerances.
Condensor Tube Sheet
— Material
The strict use of high quality raw material is guaranteed and proved by raw material certificate with each delivery. Material range is varied from ordinary carbon steel to alloy steel, all grades of Stainless Steel, non-ferrous (Brass, Al-Brass, Copper Nickel) and wide range of Clad Steel consisting of corrosion resistant materials.
