Plumbing is Installed on Propane Tank
The Plumbing Department has a built-in pit that runs the length of the vehicle. This affords complete access to the underside of the vehicle and skirting making installation of power take-offs, pumps, plumbing, and wiring faster and easier. Unlike a lift, the pit allows two or three technicians to work on the unit at the same time.
The plumbing technician removes all plugs and piping from the vessel that was used during the hydro pressure testing. BT&T discards all old plumbing, including back checks, excess flow valves, globe valves, ball valves, relief valves, etc. Only three items are rebuilt on a BT&T refurbished unit – the meter, main valve and pump. Experience has shown that it’s cheaper and quicker to use new parts versus rebuilding. For example, to properly rebuild a globe valve it needs to be stripped of all of the old plumbing, completely dissembled, cabinet blasted and all threads chased. When you add labor plus parts, it’s much cheaper to install a new globe valve.
Installing and Welding Pipes
All plumbing is installed using gigs which allows perfect alignment and decreases labor time. Schedule 80 pipe, 2,000 pound forged welded and threaded fittings are used. Welded joints are also used when possible. The welded joints are checked for leaks using 400 pound nitrogen pressure. A “dummy” hose reel is used in the pre-plumbing stage and the new real isn’t installed until final assembly. The meter is fully assembled, painted and completed with attachments when it’s delivered to the final assembly department. Other attachments, such as hose ends, valves, and necessary piping, are blasted in a cabinet booth and primed prior to installing on the meter.
