Heat Exchanger Connectors

Eliminate Welded Diaphragm Seal Design

 

Existing Heat Exchangers that have chronic  leak issues, or are using sealing technology that is difficult to  quickly open/close, are ideal for Taper-Lok®.

Leaking welded diaphragms of high pressure  heat exchangers in hydrotreating and hydro-processing service units are a  serious problem for the petrochemical industry. The welded diaphragm is  located just in front of the tube side cover plate and is highly  stressed due to the combination of high pressure hoop stress and large  compressive forces from the cover plate bolting. The strenuous  environment and thermal cycles stimulate corrosion cracking at the weld  of the diaphragm, therefore causing a path for leaks. Reoccurring  equipment failures demand that the units be taken out of service for  weld repairs, temporary clamp installation, or welding of new metal  diaphragms. Heat exchanger repairs are very costly due to the  decommissioning of the entire drive train, as well as the lost  opportunity from extended downtime.

Replace with Taper-Lok®

 

Eliminate all problematic welding and  simplify the design by using the Taper-Lok® seal. The basic converging  angle seal geometry wedges itself between the cover plate and channel  wall to create a pressure tight seal. The seal is self-energizing and  pressure-enhanced, which results in an even tighter seal and reliable  leak-free service.

The elimination of the weld also allows  opening/closing of the exchanger to be up to 80% faster. As a result,  our customers can typically save up to $400K each planned shutdown for  each exchanger. Customers can also potentially save $Millions in lost  production during unplanned shutdowns due to less cost for parts,  service and less days of downtime.

We can retrofit your existing heat exchanger  that has a welded diaphragm seal design and change it to Taper-Lok  during your next planned or unplanned shut down. The retrofit process  can be done during regularly scheduled maintenance outages.

We can also work with heat exchanger  manufacturers to design the channel flange and tube sheet with our  incredible and simple design.

Taper-Lok Wide-Area Seal Technology

 Taper-Lok Connectors metal-to-metal seal ring technology offers  leak-free reliability over traditional ANSI and API gaskets. Our seal  rings offer the equivalency of welded joint integrity and can be used in  critical and chronic leak areas. Many “metal to metal” ring type  connections rely on a narrow band of contact.  In principle, this will  be enough, but in practice, in field conditions they are easily damaged.  Taper-Lok incorporates a Wide Area Seal that is up to 20 times the  contact area of other metal to metal seals.  Ensuring a robust and  forgiving connection that can easily withstand the rigors of repeated  job site connections in tough conditions.
