Flange Washers Solve Gasketed Joint Leaks for Heat Exchangers
A processing plant had a leaking heat exchanger. The heat exchanger’s
primary fluid, Hexamethylenediamine, was subject to a 500-600ºF temperature swing and rapidly developed massive leaks at the gasketed joint. Different gasket materials and bolting techniques were tried, in addition to the ultrasonic measuring of the bolts in conjunction with hydraulic bolt tensioning, without success.
Solon's Flange Washer Solution
Solon® Flange Washers were recommended and installed using normal assembly techniques which resolved the gasketed joint leak seamlessly.
There are many variables that occur in a typical flange assembly including; differential thermal expansion, tool inaccuracies, plastic deformation of components, or complex elastic interactions. Mathematical reasoning, laboratory experimentation, and field experience indicate that Belleville spring flange washers are an effective method of creating a more reliable flange assembly.
Solon Flange Washers are designed to maintain sufficient bolt tension and resultant gasket pressure in high temperature and high-pressure applications where safety and emission containment take priority.
