Valve gasket issues
Thread Content
Our company has an imported valve in use, with the following specifications: Serial number, Valve tag number, Installation location, Valve specification/model, Operating conditions, Quantity, Nominal diameter, Remarks, Medium temperature (°C), Pressure (Mpa gauge). 10256-C-209A/B, Sulfur warehouse; DN150/DN80, -2.0, Liquid sulfur. 1350.42. The valve is connected via flanges; could someone please advise me on what type of gasket would be the most cost-effective choice?
Polytetrafluoroethylene PTFE works
Since it is liquid sulfur and it involves low-pressure RF flanges, it is recommended to use stainless steel wound gaskets
I think using PTFE gaskets is the best choice – for high temperatures and corrosion resistance
It is reasonable to choose wave-tooth composite gaskets; their frame is made of S.S. and the filler is graphite, allowing for long-term use after a single installation
Using stainless steel wound gaskets is definitely no problem; we mentioned this issue in the design for liquid sulfur here.
