Crall Products Corporate Name Change

Crall Name Change to WW Tank & Vessel

In 2003 WW purchased the assets of Crall Products Inc., a long-standing manufacturer of Code pressure and filtration vessels & elements, swing-bolt closures, paraffin scrubbers, visual couplings, rod hangers, Bos-Co pipe supports & straps and other oilfield-related production equipment. In 2004 we began manufacturing steel API oilfield tanks to compliment our fiberglass API tank line and in 2005 built a new 21,000 sq. ft. tank manufacturing shop to meet the growing oilfield demand for steel tanks. This led to the addition of code steel oilfield production equipment in 2009 such as heater treaters, gas separators, free water knockouts, coalescers and gunbarrels. In 2018, the name of Crall Products was changed to WW Tank & Vessel Co. to better align and identify ourselves with the WW Tank family of companies.
