Mueller recently began in-house heat treating operations utilizing a new oven system custom fabricated in our own shop.
"With our expansion last year we took some dramatic steps toward bringing all of the processes necessary to build our equipment under our own control," said Tommy Tamayo, Mueller's Vice President of Manufacturing. "Our heat treating facility is the result of a couple of those steps. Not only did we add the necessary space, we also added significant heavy fabrication equipment which we immediately put to use building the heat treat furnace. It is working just as we planned and enables us to save the time and expense of transporting vessels to and from another facility."
The accompanying photo shows our EnerPac gantry crane lowering the massive oven over a high pressure carbon bed deodorizer prior to the 12 hour procedure in which the vessel will be subjected to temperatures up to 1150 degrees. The furnace utilizes two 1,000,000 BTU propane burners. During the operations the unit sits atop an eight inch bed of crushed granite to diffuse the extreme heat, preventing destruction of the building's concrete foundation.
At 40 feet long, 12 feet wide, and 12 feet high, the unit can accommodate most of the vessels we manufacture. An even larger exterior system is also planned to handle our biggest slug catcher vessels which can reach up to 50 feet in length seam to seam, and 96 inches interior diameter.
