Pipe straight-through sight glasses HGS07-101～108, tee sight glasses HGS07-115～122, glass tube pipe sight glasses HGS07-126～127. Does anyone have them? Could you send them to me? Thank you so much.

I also looked around, but couldn’t find a place to download it.
I work on accessories related to special materials; currently I’m dealing with sight glasses that meet the HG21619 and NB/T47017 standards. Yesterday, when I encountered one of these sight glasses, I didn’t know where to start.
I’m used to working with standard, conventional tasks; it’s fine when there’s a large volume of non-standard work, but when the volume is small it becomes unprofitable. Sometimes it’s also embarrassing to have to turn down requests from old clients. It’s possible that some components are proprietary to a particular manufacturer; it’s hard to say for sure. Origin and standards, innovation.
Yes. These rarely used products are very difficult to deal with. I’ve looked everywhere; it seems to be HGS07. Some sources refer to it as a part number, and it doesn’t appear to be a standard product.
For non-standard items, the other party needs to provide detailed drawings; otherwise, it’s impossible to determine the manufacturing process, structure, pressure resistance, material, and sealing performance.
It’s the drawing number. It is available in the \"Piping Handbook for Chemical Industries\" - Volume 1 - P330. Note: It is the old version. Blue cover
