Help calculate the depth of insertion for the thermometer
Thread Content
I’m asking fellow sailors: how should the insertion depth of a bimetallic thermometer be measured, and from where to where? A thermometer needs to be installed to report data as per the plan. Help me figure out which length on the drawing represents the insertion depth

The actual value is 25; everything below the sleeve interface is considered to be at the proper insertion depth, so the effective value is 25.
According to the specifications, this pipe needs to be expanded.

From the diagram, it appears that the bimetallic thermometer is installed in an inverted position; the insertion depth is approximately 240 – 141.5, which equals around 100. The other component seems to indicate that the interface, when installed in the correct orientation, has a diameter of φ35 and features internal threads for connecting to the thermometer core, while φ15 represents external threads for connecting to your galvanized pipe. But the diameter of the temperature measuring tube is too small, and it needs to be enlarged.
The insertion depth should be calculated based on the connection process; generally, adding 150 mm to the insertion depth gives an approximate length for the entire product. It’s easier to understand if you view Figure A upside down; this diagram is used to treat cervical spondylosis: lol
240-141.5, insertion depth measured from the sealing surface. The specifications require that pipes smaller than DN80 be enlarged to DN80. We have also seen installations done in the way described by the original poster, and no major problems were observed.
The sleeve, plus two-thirds of the pipe diameter, constitutes the insertion depth
The size of this pipe is also too small; there are 2 methods； 1. It is recommended to expand the pipe diameter to DN80 (to create a tee; the length required depends on the distance from the flange or threaded connection provided by the instrumentation team to the center of the pipe) ； 2. Due to limited on-site conditions and low requirements, it is sufficient to make an opening directly at the 25-degree elbow and then insert the thermometer; there is no requirement regarding length ；
