Types of gaskets used in plate heat exchangers

 

Nitrile (NBR) Gaskets

Known for their excellent resistance to oils, fuels, and chemicals, nitrile gaskets are often used in applications where compatibility with hydrocarbons is essential. They offer good temperature resistance and are cost-effective.

01

EPDM Gaskets

Ethylene Propylene Diene Monomer (EPDM) gaskets have exceptional resistance to aging, weathering, and ozone exposure. They also provide excellent sealing properties against hot water and steam.

02

Gaskets

Made from fluoroelastomer material, gaskets exhibit excellent chemical resistance even at high temperatures. They are commonly used when dealing with aggressive fluids or extreme operating conditions.

03

Silicone Gasket

Silicone gaskets offer high-temperature stability along with good flexibility and electrical insulation properties. They are often preferred in food processing industries due to their FDA compliance.

04

PTFE Gasket

PTFE gaskets provide outstanding chemical resistance across a wide range of substances while maintaining low friction characteristics.

Gasketing Assembly

 
 
01
 

Incorrect/insufficient bolt tightening

This can be the result improper or inaccurate torquing procedure.

 
02
 

Operating temperature

Can be an issue when you exceed the temperature limit of the gasket. Check the gasket specification for maximum allowable temperature.

 
03
 

Bad threads/insufficient thread length

Ensure that nuts are a good running fit over the entire length of the bolt thread and that threads are long enough to allow nuts to make contact with the metal faces. Remember to have enough thread to always have a hardened flat washer. If bolt is too short, replace with a longer one.
