Nitrogen Purging and Leak Testing
To ensure safe working conditions, incoming equipment is checked for residual gas and nitrogen purged before any work begins. Complete equipment is leak tested using nitrogen to working pressure to ensure a leak free condition. Specialty Gas equipment at the request of the customer can be helium/nitrogen leak inspected using a helium mass spectrometer. Additionally equipment can be heated and vacuumed to reduce residual moisture.
Tubes are removed and sent through an automated shot-blast machine that removes appropriate coatings and provides a white metal blast condition ready to accept paint. Chassis and MEGC frames are blasted to a white metal condition in a 12 ft wide x 50 ft long shot-blast booth.
Flange Removal & Thread Inspection
In accordance with DOT requirements Weldship performs neck flange removal using state-of-the-art hydraulic tools to allow complete neck thread inspection.
Tubes are moved into the paint booth where they receive multiple coats of paint in accordance with the customer’s specifications. Tubes are positioned to ensure complete coverage. Blast profile and subsequent paint thickness is measured to assure specifications are met. Following assembly of tubes to trailer or MEGC, the unit is re-painted a second time in one of Weldship heated paint booths.
