FlangeTec® ASME-API
The FlangeTec® ASME/API Compact Flange Series is a high performance flange system used as an alternative to conventional ASME and API flanges. Offering high integrity sealing the FlangeTec® Series accommodates High Pressure and High Temperature service especially where high external loads are present. Utilized in a multitude of Industries and applications, the FlangeTec® CF Series offers dramatic weight and space savings when compared with Standard ASME and API Flange systems used in process piping, pressure vessels and OEM equipment. Uniquely offered for standard Industrial service as well as custom ranges for High Temperature (HT Series) for specific operating conditions from 500°F (260C°) to 1600°F (538°C). The FlangeTec® CF API Series is now available through 20,000psi from -75°F (-60C°) to 650°F (+343°C), and PR2F qualified.
