- What problems can be caused by Pressure Spikes?
Very high pressure spikes can occur in any line pumping a liquid if a valve is closed rapidly, leaving the fluid flow nowhere to go. The inertia of th Read more...
- Which gaskets can I use for FDA applications?
There are quite a few classes of materials that are safe for use in Food applications, and thereby FDA compliance. Phelps Style 7205 is F Read more...
- Does the use of (Heat) Traced Lines affect the gasket joint?
Heat traced lines pumping materials can present a number of problems for gaskets: The bolts are usually hotter than the flanges since the heat is a Read more...
- How do I fill a large gap in flanges? Can I stack gaskets? (Spacers in Flanges)
We understand that some installations require a very thick gasket to fill a large gap between flanges. In such scenarios, we do not recommend stacking Read more...
- What do I need to be concerned with when Gaskets are installed in Grooves or recesses?
Gaskets installed in grooves or tongue and groove flanges require one extra consideration: the compressed height of the gasket must be considered. Thi Read more...
