A Gulf Coast Chemical Company had a leaking weld-o-let. Another contractor's attempt to repair the leak failed. Team was called.

An onsite inspection of the leak by Team technicians revealed the problem. The customer's system on this particular feed line was cycling from -50°F and 900 psig (Hydrogen and CO) to 400°F and 2 psig (Nitrogen). Team technicians measured the leak, gathered the onsite data and forwarded the information to Team's engineering department.

Team's engineering discussed the cycling problem with the company's Sealant's Department, then designed an enclosure with flexible packing-seal end plates to handle the cycling. Drawings and calculations were approved by the customer.

The enclosure with its special packing assemblies was manufactured by Team, then safely installed. Bolts were torqued to recommended values for cycling. A combination of proprietary Team sealants was injected; to seal the perimeter of the enclosure, then to fill the enclosures void.
