Tests of the durability of the Carbide Blast Joint have been run by both independent laboratories and by our customers. In an individual laboratory test to compare the resistance of various blast joint designs to high pressure water and sand, the Carbide Blast Joint proved many times superior. Sample construction, and results, are shown in the table.

Test conditions for all blast joints:

  • 90 psi air
  • 3.5lbs. sand per minute
  • 1/4" nozzle with 3" stand off using No. 3 (16-40 mesh) sand
  • 40% humidity
