The BF type is a flanged thermowell, connected to equipment or piping via a flange for reliable sealing, suitable for high-pressure and high-pressure-differential conditions. Available in integrally forged (01), integrally drilled (02A), integrally drilled split (02B), integrally drilled embedded (02E), steel tube (03), and 04/05 types with extension. BF01 and BF02A are suitable for high-pressure applications such as Class1500, Class2500, and 10000PSI. Flange specifications are designated as standard code-nominal diameter-pressure rating-sealing face, and can be supplied to standards such as HG/T20592 and HG/T20615.
