      • All hose should be externally inspected prior to each use and thoroughly inspected every six months or sooner
      • All hose should be hydrostatically tested to 1.5 times working pressure (or to appropriate industry standards) every six months to verify the hose assembly’s integrity
      • Hose must be depressurized and laid out straight prior toinspection
      • Coupling selection should be made with the intent of providing the maximum level of safety with the best performance capability possible

      Inspect Daily For:

       

      Corrective Action:

      1. Look for cuts, gouges, or worn spots in the hose cover that expose textile or wire reinforcement.   Remove hose from service. Contact Apache for repair instructions.
      2. Inspect for soft spots, bulges or blisters in cover, sections of mashed flat hose or kinked areas.   Remove hose from service. Contact Apache for repair instructions.
      3. Carefully examine a length of the hose (18" in length adjacent to where the coupling is attached) for any damage such as kinks, soft spots, cover cracks, or permanent deformation of the hose from its original form.   Remove hose from service. Contact Apache for repair instructions.
      4. Check couplings for any slippage which is evidenced by misalignment of the coupling or scored/exposed areas on the hose cover next to the coupling which indicates movement of the coupling.   Remove hose from service. Contact Apache for repair instructions.
      5.Check couplings for worn threads, loose clamps or bands, worn gaskets, worn or broken handles, cam-arms and pins.   Remove hose from service. Remove suspect couplings from the hose and replace with new coupling.
      6. Inspect for hose cover blisters or loose outer cover. This may indicate conveyed product is passing through the carcass of the hose.   Remove hose from service. Contact Apache for repair instructions.
      7. Before each use look down the inside of the hose couplings for damage or blockages.   If broken parts or blockages are found, remove from service.
      8. Inspect couplings for any worn parts that may prevent normal function, damage to any safety device that prevents them from working, worn threads, excessive corrosion or rust, or cracks in any part of the coupling.   Remove hose from service. If possible, remove suspect couplings from the hose and replace with new coupling.
      9. Look for changes in cover color. This may indicate chemical attack.   Remove hose from service. Contact Apache for repair instructions.
