We've had fittings seize on gas cylinders before. Could you send over a photo and confirm if it's a CGA or DISS fitting? I will check with our production team how they've handled this in the past. </div>

<b>Subject:</b> [labnetwork] Removal of Silane Cylinder</font>
<div> </div>
</div>
<div>
<div dir="ltr">
<div>Hi all, </div>
<div><br>
</div>
<div>Columbia Nano has a silane cylinder that needs disposal. Unfortunately, the gas line can't be removed from the cylinder because it's seized on, so I disconnected the line. It remains connected to the cylinder and is about 4 feet long and is bendable. The
cylinder is around 20-30% full and is small, size 40 CF. </div>
<div><br>
</div>
<div>Because the line is attached, the cylinder can't be shipped as is, and it requires a cylinder overpack. </div>
<div><br>
</div>
<div>I was wondering if anyone has any recommendations for a company that can do this type of work that isn't Veolia (already contacted them) or if someone has dealt with a stuck CGA fitting on a silane cylinder. </div>
<div><br>
</div>
<div>Thank you in advance! </div>
