Can manual arc welding be performed on the top of a 680-cubic-meter storage tank after it is filled with an acidic solution?
Thread Content
I would like to ask the experts: Can manual arc welding be performed on the top of a 680-cubic-meter stainless steel tank once it is filled with an acidic solution? The acidic substances in question are mainly sulfates, inorganic salts, xylitol mother liquor, and wastewater generated after xylitol extraction
Welding can be carried out in the absence of explosive materials.
May I ask what are the explosive materials? Thank you
There are too many explosive materials. Oils, alcohols, liquefied gases, etc.
For gas detection in the upper space, it is necessary to check for flammable and explosive gases, and also consider the safety of the workers carrying out the construction.
Firstly, welding cannot be carried out when there are flammable and explosive gases in the vapor phase above the tank~~~~ Secondly, from a risk perspective, it is better not to perform welding under such conditions
