Heat Exchangers and Accessories
Heat Exchangers come in many different types and styles the most common of which are ‘Shell & Tube’ and Plate (Brazed and Gasketed). All styles do the same job – exchanging heat from one area to another…whether is from steam-to-liquid or liquid-to-liquid.
Whichever type it is, two elements are at work to shorten the lifespan of the heat exchanger – corrosion and erosion.

Call or email us to discuss your project requirements and ask us any questions.
If you are simply looking for a new tube bundle and can do your own measurements, fill out our downloadable PDF and email it to us for a quote. If you are looking for a complete heat exchanger & tube bundle solution, contact us for more information and to discuss your project requirements.
Review the quotation you receive from us. Depending on the scope of the item requested, there may be drawings that will need to be approved before any fabrication can begin.
Send us your purchase order referencing our quotation number.
Wait until product fabrication has been completed and for your new shell & tube heat exchanger to arrive. We can ship anywhere in Canada and the United States. Either send us your courier account for shipping, or ask us about prepaid & charge shipping options.
Heat Exchanger Styles
Heat Exchangers allow the transfer heat from one fluid to another without having the two fluids mix, whether for heating or process purposes. There are two common types of heat exchangers: “Shell & Tube” and “Plate”.
Shell & Tube
A shell & Tube heat exchanger is when there is fluid flowing through two components. There is one fluid going through the tubes on tube side and another flowing through the surrounding pressure vessel on the shell side. The purpose is to exchange heat from one component to the other.
A plate heat exchanger involves two fluids flowing across alternating grooved plates, moving heat from one to the other without meeting. Plate heat exchangers can be built with replaceable gaskets holding the plates together in a frame (plate & gasket), or the plates can be braised together (braised plate).
Replacement Tube Bundles & Gasket Sets
Tube bundles are available for a huge range of shell & tube heat exchangers, coming with new gaskets for installation. These allow you to use the existing shell and give your heat exchanger a new life.
Stand-alone gasket sets are also available for when you need to inspect and reassemble a heat exchanger.
Copper Tubes & Carbon Steel
All Stainless Steel

Do you have questions about Heat Exchangers and Accessories?
What is the difference between corrosion and erosion?
Corrosion is the wearing away of metals due to a chemical reaction (e.g. chemicals used in water treatment reacting with elements of the heat exchanger). Erosion is the recession of surfaces by repeated localized mechanical trauma as, for example, by suspended abrasive particles within a moving fluid (e.g. calcium carbonate dislodged by chemical treatment impinging on plates or tubes).
How do corrosion and erosion harm heat exchangers and tube bundles?
Eventually, there will be a rupture somewhere within the heat exchanger – whether through the tubes in a ‘Tube & Shell’ or in the plates, gaskets, or brazing in the ‘Plate’ style. (Seldom does the shell in the ‘Tube & Shell’ style require attention.)
When this happens, there is cross-contamination between the chemically-treated ‘source’ media and the receiving media. This is when a choice has to be made…do you replace the existing unit with a duplicate new unit, or do you repair the existing unit?
What is the material makeup of tube bundles provided by Keystone?
Tubes are available in Copper and Stainless Steel (both 304 and 316) while the tube sheet is available in Carbon Steel, Brass, or Stainless Steel (both 304 and 316). A set of inner and outer gaskets accompanies each RTB. All tube bundles come with the CRN stamped into the tube sheet.
