Have you ever had a $45,000 piece of equipment show up in your facility, and thought: “I don’t remember what this is for…”? Well, I had this exact thing happen to me. I was fortunate in that the 900 pounds of equipment sitting in the shipping bay was a simple mix-up with the company delivering our equipment. Crisis averted! However, in many instances mistakes like this can lead to the loss of funds, and sometimes even jobs. The responsibility often falls to project managers to have a crystal-clear picture of the flow of parts and equipment coming in for their systems.
Sealing anything at cryogenic temperatures requires extremely tight tolerances. If tight tolerances are not considered, holes may open at the source of the seal, allowing cold leaks to occur as referenced in this past post. In today’s How To, we’re going to discuss how to weld tubes together utilizing orbital TIG welding. Orbital welding has given the lab an advantage in that all our welds minimize human error and the whole operation is computer automated. The system being used is Swagelok’s M200 orbital welding system, which was donated to our lab through the Boeing Cybergrant program. The procedure is as follows:
