Threaded Products for Use in Heat Exchangers

precision-roll-threaded-bars-heat_thumbAt Keystone Threaded Products, we’re known for providing the highest quality roll threading for a wide range of products and applications.  One of the popular uses of our precision roll threading services is for threaded bars and nuts used in heat exchangers.  So what exactly is a heat exchanger, and what do our services do for them?

In simple terms, a heat exchanger is a piece of equipment that assists in the transfer of heat from one fluid to another.  Common uses for heat exchangers include refrigeration, air conditioning, sewage treatment, power plants, automotive production, petroleum refineries, and natural gas processing.  Along with tie rods and special tabbed nuts, heavy steel end plates compress a series of internal plates, together forming a heat exchanger unit.  As opposed to other types of heat exchangers, plate and frame heat exchangers are considered to be advantageous, as the fluids are exposed to a much larger surface area, and as such, are the design of choice.

As specialists and leaders in our industry, we at Keystone Threaded Products can provide a complete range of tie bars and specialty tabbed nuts in sizes and designs specific to your manufacturing applications.  We are also able to provide corrosion-resistant materials at highly reasonable prices, making us the preferred supplier of some of the most premier, renowned heat exchanger manufacturers in the country.  Our experience and expertise has made these industry-leaders value and trust our products with theirs, and we’re confident in our work in this area, as well as with all of the industries and applications we serve.

Thread Rolling: How it’s Done, and What Makes it the Best Choice

Since 1920, Keystone Threaded Products has manufactured the highest quality roll-threaded products available.  Thread rolling, which is the most common process of thread forming, offers numerous advantages over the alternate method of cut-threading.  These advantages include cost-savings in both raw material and overall manufacturing, improved thread strength and consistent quality.  Rolling is also a faster process than cutting.   Cold working of the material during thread rolling makes the threads stronger and more fatigue-resistant than cut threads.

Chances are, you’ve been in contact with threaded rods as their applications are vast.  For example, your favorite roller coaster is secured to the ground using anchor bolts.  The orchestra pit at the theater is raised and lowered using threaded rods.  Your car, truck or camper may have a screw jack.  Water control systems, heat exchangers, gates, mines, satellite trucks, even coffins have threaded rods as components.

Whichever application and product you need, we are confident you will be thrilled with the quality of our manufacturing.  We’d love to discuss thread rolling in more detail. Please feel free to check out our website, or give us a call at 216-524-9626 for more details!
