Specifications for integrated hot tap fittings

The hot tap fitting is designed for pressure loads of max. 16 bar abs. To ensure
interchangeability with standard pipe components (type 1), the wafer version (Fig. 8) has been
developed for DN 50 and DN 80 DIN flanges with a pressure stage of PN 40. In the case of the
DN 65 version with a pressure stage of PN 16, you should use connection flanges with 4 screw
holes. Imperial versions 2 ... 8" designed for connection flange ASME B16.5 Cl.150 only. For
suitable flowmeter sensor lengths, see Fig. 6.

Installing the wafer version

Fig. 8 (left) shows the installed wafer version of the hot tap fitting in the disassembly position.
The guide tube is in its upper end position and seals the Sensyflow opening (right).
By means of the flat gaskets, the hot tap fitting is sealed on both sides against the mounting
flange of the pipeline. To ensure maximum measurement accuracy, it must be centered exactly
between the flanges (see Fig. 3). It is very important that you observe the proper flow direction
(arrow on pipe component).
