Mueller Brings Heat Treating In-House

A gantry crane lowers the 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°F (621°C).

Mueller Environment Designs Inc. has begun in-house heat-treating operations utilizing a new oven system custom fabricated in its 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, Vice President of Manufacturing at Mueller. “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 furnace utilizes two 1,000,000 BTU propane burners. During the operations, the unit sits atop an 8-in. (203 mm) bed of crushed granite to diffuse the extreme heat, preventing destruction of the building’s concrete foundation.

Measuring 40 ft. long, 12 ft. wide, and 12 ft. high (12 m x 3.6 m x 3.6 m), the unit can accommodate most of the vessels the company manufactures.

Headquartered in Brookshire, Texas, USA, Mueller Environmental Designs Inc. engineers and manufactures separation, silencing, deodorization, mist elimination, intake, and exhaust systems for the natural gas industry.
