Are there standard drawings for wet gas cabinets?
Thread Content
This is the table from HG/T 21549.4-95 \"Series of Steel Low-Pressure Wet Gas Cylinders\" – are those in the red boxes the standard drawings? I would like to ask where I can find this standard diagram?
I don’t understand; is the atlas another standard? Please explain in detail, teacher!
An atlas is just a set of drawings; it needs to be purchased!
HG/T 21549.4-95 \"Series of Steel Low-Pressure Wet Gas Cylinders\" is complementary to HG/T 20517-1992 \"Steel Low-Pressure Wet Gas Cylinders\"; both were developed by Hefei Huasan Third Research Institute. Previously, it was possible to purchase copies of these standards from Huasan Third Research Institute. As more than 20 years have passed, the standards for materials, flanges, fittings, etc., specified in their standard numbers have changed, so they can no longer be used directly; at best, they can serve only as a reference.
It’s also great as a reference. Do you have this, or where can it be downloaded?
The parameters can be referred to in the tables provided in HG/T 21549.4-95 \"Series of Steel Low-Pressure Wet Gas Cylinders\", but according to the original standard drawings, it is recommended that once a specific drawing number has been selected, one should seek assistance from the staff at Donghua Engineering (formerly the Third Research Institute of Chemistry) to obtain the corresponding set of standard drawings for reference. There are too many sets of drawings in the entire series, making it generally inconvenient to provide them.
Thank you, teacher! I have another question: can a spiral-type gas holder of the same volume be converted into an upright gas holder? Are there any things to note?
It may be possible to convert a single-ventilation cabinet of modest size into a vertical type； Changing multiple thermostat cabinets to a vertical type is quite difficult.
