Petrochemical & Refinery

Perfect for Petrochemical and Refinery Applications

 

Our Engineered Connectors have  55 years of leak-free service in critical petrochemical and refinery  applications.  In many cases, our connector assemblies are less  expensive to purchase than the corresponding ANSI or API flange  assembly.  We can retrofit your chronic leaky flanges and exchangers  on-site to the Taper-Lok or CofferLok design.  These connection systems  are even better in high pressure and/or high temperature applications.

Taper-Lok® Zero Gap Connector –Zero Fugitive Emissions

 Taper-Lok® Zero Gap Connector has a smooth internal bore that works well  to reduce erosion and corrosion. It offers a through bore, as the male  nose is landed onto the female flange to eliminate the gap between the  two flanges. The resulting through bore significantly reduces problems  with crevice corrosion and polymer solidification. The zero gap offers  an advantage in critical services with crevice corrosion, such as  Alkylation Units with hydrofluoric acid and sulfuric acid. Flanges in  these highly corrosive environments suffer from significant  corrosion specifically in the crevice between the two flanges. 

CofferLok Clamp Advantages over ANSI B16.5 Flanges

 Self energized and pressure energized seal.  Seal ring is designed to be  reusable.  Small relative movements between hubs can be accommodated by  seal ring deflection.  Clamp assembly lighter and requires less space.   Clamp bolts are oriented perpendicular to pressure end thrust and are  not subjected to hydrostatic loading due to pressure.  Small outside  dimensions allow use in more congested areas.  Clamps can be  conveniently rotated for desired bolt orientation.  Four bolt design has  built in safety factor which allows for bolt failure without loss of  sealing integrity.  The connectors method of sealing does not require  precision bolt loading, thus easier to make up.  Reliable 1 X10-6 cc/sec  leak detection (one part per million). 

How Much Does A Flange Leak Cost?

 Every plant has some type of flange leak.  In many cases these leaks are  in critical parts of the process.  Leaks can cause plant shut downs and  cost $millions in lost production. We can retrofit your chronic leaky  flanges during your next planned maintenance to our metal seal  technology and eliminate leaks.
