What are the connection methods for bimetallic thermometer joints, and what are the prerequisites for using each connection method?
The connection methods for the joints of bimetallic thermometers are divided into the following four types: 1. Adjustable pipe joint, 2. Pipe joint (external thread), 3. Pipe joint (internal thread), 4. Fixed thread
There is a type of fitting called a thermometer expansion tube; how is it used?
When the pipe diameter of the pipeline is less than DN80, an enlarged pipe is usually selected; holes are then made in this enlarged pipe and straight joints are welded to it before the instruments are installed. An expansion tube is installed to ensure measurement accuracy.
When the pipeline diameter is less than DN80, an enlarged pipe is usually used; a straight joint is then welded by drilling holes in this enlarged pipe. There are two types of enlarged pipes: those with concentric diameter reduction and those with eccentric diameter reduction, after which the instruments are installed. An expansion tube is installed to ensure measurement accuracy.
In addition to threaded connections, bimetallic thermometers can also be connected using flange connections or welding!
