Patent ID: 7275550

Claim:
A method for cleaning and pressure testing tubular structures with a common apparatus, the steps comprising: providing a cleaning and pressure testing apparatus having a cleaning fluid reservoir, and a rinse fluid reservoir, and wherein the cleaning fluid and rinse fluid reservoirs are configured to be in fluid communication with one or more catch basins; engaging a first end of at least one tubular structure to an output interface of the apparatus; engaging a second end of the at least one tubular structure to an input interface of the apparatus; maintaining engagement of the first and second ends of the at least one tubular structure with the apparatus while sequentially flowing a cleaning fluid from the cleaning fluid reservoir through an interior of the tubular structure and into the catch basin; flowing a rinse fluid from the rinse fluid reservoir through the interior of the tubular structure; preventing the rinse fluid from flowing into the one or more catch basins; pressurizing the rinse fluid within the tubular structure; and monitoring the pressure of the rinse fluid while the rinse fluid is pressurized within the tubular structure.
