TLI has flanges for the entire range of UHV applications. Clamp-type wire seal flanges are used where an existing flange must be matched or space requirements preclude the use of bolt-type flanges. Standard sizes vary from 12" tube to 36" pipe diameters. Custom flanges can be supplied.
As is the case with all TLI UHV flanges, the clamp-type wire seal flange is made of type 304 stainless steel. It is usually used with a .090" diameter OFE copper gasket for bakeout temperatures of up to 450°C. For leak checking or use at temperatures below 120°C, a reusable Viton® gasket may be used. Note that these gaskets are not interchangeable with bolt-type wire seal flange gaskets.
To ensure long-term seal reliability under repeated bakeout at elevated temperatures, super-high tensile strength clamping hardware is supplied, thus matching the thermal expansion coefficient of the flanges.
NOTE: Wire seal blank flanges with a domed head insert are available at reduced prices. Consult the factory for information.
