Applications:

  • Light Gas Guns
  • Compressed Gas Guns
  • Ordnance Barrels

Size capabilities:

  • Length = 40 feet (12.2m) maximum
  • OD = 24" (0.61m) maximum
  • ID = 0.48-14.00" (12.2-356mm) range

Manufacturing processes include:

Deephole Gundrilling

  • Extremely straight bores
  • Extremely concentric relationship between ID and OD throughout length of the barrel

Deephole Bottle Boring

  • Complex bore profiles at unlimited depths
  • Capable of smooth constantly tapered bore shapes (slightly reduced ID size on muzzle end to compensate for OD size loss of the sabot)

Reaming

  • Counterboring existing barrels to enlarge ID size and/or correct crooked bores

ID Honing

  • +/-.001" (.025mm) size variation
  • 4 Rms surface finish

ID Burnishing

  • Compressive layer of coldworked ID surface

Large diameter and long length lathe machinery

  • Precise OD sizes on long length barrels
  • Precise perpendicularity of end faces
  • Complex external and internal machined end features

Large diameter and long length mill machinery

  • Complex radial features (ports) and end features

Additional

  • Precision straightening long lengths
  • Measuring and reporting ID straightness, OD/ID concentricity, ID surface finish, OD straightness
  • Saw Cutting
  • Welding
  • Full material traceability

Why Call National K Works for Your Light Gas Gun, Launch Tubes & Barrel Boring Needs?

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 CFD thermal modeling, and application of proprietary knowledge that spans decades and already includes over 500 vacuum flask designs, our team continues to exceed expectations.

For forty years, the company has enjoyed the good fortune of being located in West Houston's energy corridor. It puts us close to customers, and close to communities that are great places to live.

For over 40 years, NKW has designed and manufactured innovative pressure and temperature solutions for customer instruments deployed in hostile environments. NKW's expertise is world renowned for high-pressure/high-temperature (HPHT) vacuum flasks and pressure housings. Many NKW flasks remain in service decades after they were born.

We look forward to helping you with any light gas gun design projects, barrel boring needs, or launch tube services. Contact us today to learn more!
