National K Works

For over 40 years, NKW has designed and manufactured innovative tools and components, primarily for the extreme drilling and geothermal markets. NKW's expertise is world renowned for high-pressure/high-temperature (HPHT) thermoflasks/Dewar flasks, thermohousings/pressure housings, and MWD/LWD drill collars. Many NKW flasks remain in service decades after they were born. Maybe that's why our customers know their NKW flasks by name, literally. NKW also provides its customers with expertise and insight even before manufacturing our tools, during the concept development and design for manufacturing (DFM) phase. From concept, through FEA, in-depth modeling, and application of proprietary knowledge that spans decades and already includes some 500 flask and housing designs, our team continues to exceed expectations. Equipped with its engineering-led, proprietary machining capabilities, NKW is expanding into new, related markets where its expertise in extreme HPHT engineering can flourish. These new markets include aerospace, defense, process and industrial research. For example, NKW is now qualified to manufacture NASA Class 1 Life-critical Spaceflight Hardware. The company's activities also include engineering and testing services, and on-demand hobby shop support to clients' engineers.
