W & W FIBERGLASS TANK CO. was formed in May of 1978. The original production line of our company was a simple two-piece tanks only business. In June of 1985 we installed a filament winding machine with 10' and 12' mandrels. A major plant expansion in 2014 and the addition of an additional 12′ and 15’6″ mandrel allows us to build tanks up to 1000bbl.  Since that time our company has built small tanks, specialty tanks, custom built tanks, and has been active in repair work.  We now specialize in stock tanks, oil storage and potable water storage tanks. We also custom fabricate tanks for chemical, environmental, water and wastewater industries including RO (reverse osmosis) Systems, DI (De-Ionized Water) Systems, oil removal, solution storage clarified water storage, waste water and much more.

In 2003 WW purchased the assets of Crall Products Inc. in Pampa, Texas, a long-standing manufacturer of Code pressure and filtration vessels & elements, swing-bolt closures, paraffin scrubbers, visual couplings, rod hangers, Bosco pipe supports & straps and other oilfield-related production equipment. In 2004 we began manufacturing steel API configured oilfield tanks to compliment our fiberglass oilfield tank line and in 2005 built a new 21,000 sq. ft. tank manufacturing shop to meet the demand for steel tanks. This led to the addition of code steel 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.

In 2008 WW opened a fiberglass manufacturing facility in Ft. Smith, Arkansas to serve the Oklahoma, Arkansas and Lousiana markets. This facility also builds most of our custom and dual-wall containment tanks.

In 2018, following a fire at our main fiberglass plant in Texas, WW acquired the assets of Freedom Tank & Fiberglass Co. in Wewoka, Oklahoma. With the assistance of the Wewoka Industrial Authority, WW expanded the facilities and opened WW Tank Oklahoma, building fiberglass tanks for the Oklahoma and North Texas oilfield markets.


In additional to manufacturing fiberglass and steel tanks and vessels, WW also specializes in tank delivery and battery setup including full catwalk production capabilities.  Whether your site is across town or across the country, WW can deliver your tanks to your location quickly, dependably and economically and set them on your pads with our fleet of knuckle-boom outfitted semi's, oversize escorts and professional & highly experienced personnel. Through our trucking division we are able to offer economical delivery throughout North America.  

In our 40+ years of business we have weathered the ups and downs of the business cycle. have experienced the rise and fall of oil and gas prices based on foreign control, economic change, and competition. With this in mind, WW is dedicated to giving companies all the support it can through quality, service, and fair prices.

We attribute our success to God, fair business practices, quality control, and customer satisfaction.
