Installation of Wiggin’s type dry gas holder legs
Thread Content
Who knows about dry gas cabinets? Question: Installation issue with the legs of Wilkins-type dry gas cabinets: The legs are removable; they are usually removed and blind flanges are installed in their place. Question: How do I proceed when legs need to be installed? After the medium is emptied, the piston drops to the bottom and cannot be installed ； It’s impossible to remove the blind flange under pressure. The drawings I saw were structured in this way, and it hasn’t been put into practice yet. I have a question.
Our company has also just installed a 10,000 M3 gas holder. I share the same confusion as you: under normal circumstances the legs are not installed and are only used during maintenance, but how are they installed at that time? Could it be installed under pressure?
Press down to remove and install all legs. That’s how we usually carry out the installation and debugging.
