Help: Some minor detail issues
Thread Content
1. For the exhaust pipeline of the open-type safety valve using steam as the medium, do you install a drain tray during the design process? Is it possible to do without a hydrophobic tray in such cases? 2. To what extent should the insulation design for instruments and valves be thorough? Which standard specifies it? Is there any specification for the design depth when steam tracing is used for the 3 pipes? When is steam tracing used? Under what circumstances is electric heating used? 4 In which areas cannot boilers be installed outdoors? The standards usually state what methods are advisable to use, rather than specifying in what situations certain approaches should not be employed, which is quite frustrating. 5 How should the insulation thickness of outdoor water tanks in northern regions be determined?
I’m not very familiar with this area; you can check the relevant manuals to see if there are any specified standards or something, or search on Baidu
