3.8.6 Weld-on stainless steel socket
The ORBISPHERE 29501 weld-on sensor socket can be used to install a sensor into a stainless
steel pipe (min.Ø 50 mm or 2”). When welding the socket to the pipe, check that setback
between the pipe’s inner diameter and the sensor tip does not exceed 4 mm (see diagram).
Note: Be sure to remove the two O-rings from the socket before welding and leave the sensor’s stainless
steel cap screwed on during welding to prevent thread distortion.
Recommendation:
To facilitate sensor removal and installation, we suggest installing the socket in a location where
the liquid can be drained quickly and easily. By creating a one meter long piece of pipe
(Figure 20) with shut off valves at both ends, just a small volume of liquid needs to be drained to
enable sensor removal.
Also, a precise sensor and socket installation can be performed in the workshop, and this
assembly can be placed in the production line with minimal down time.
