Please help me check the parameters of this thermometer sleeve. L is the full length. H refers to the length of the sleeve inserted into the pipe, or the length of the temperature core? And what is this a? Thanks
When did you do this? The design institute actually used the old specifications to design. This was designed according to the standard of HG/T21581-1995. HK-01 is now the 2012 standard. The thermometer sleeves are all in HK-04, but they are similar. H refers to the length of the matching welding parts. L refers to the total length of the casing, and a refers to the outer diameter of the sealing surface between the casing and the weldment. If I send you a picture, you will know that the second picture is equivalent to the gasket position 1, which refers to a. Generally, there are two specifications, one is 20 and the other is 40. 20 is generally a bimetal thermometer with a small sealing surface, and 40 has a large sealing surface.
Can you send me the picture? This is a generator I bought ten years ago. I have moved it now, so it is a bit old.
