Application
- Widely used as abrasion protection wherever hoses and cables may be exposed to damage through rubbing
- Gaining widespread acceptance as an effective (though not total) barrier to the dangers of hydraulic hose leaks in the vicinity of personnel, especially in underground coal mining
- Additional protection can be achieved using two layers of DAS sleeve
- The sleeve must be securely fixed to the ferrule of the hose fitting if effective protection is to be achieved at the hose to fitting interface. Epoxied heat shrink is preferred, although other methods may be adopted
- A loose fit is preferred when seeking to gain protection against a hose leak
- Meets MDG41 requirements
Materials and Specifications
- De-aerated compact woven nylon fibres (Polyamide 6)
- In test conditions the sleeve contained the sharp stream of hydraulic oil passing through a 0.8 mm Diameter pre-drilled hole when the pressure was raised to 800 bar and held for 1 minute
- Abrasion resistance exceeds the requirements of ISO 6945 (holds up to 50,000 cycles)
- Oil retention capability of 100 PSI pressure for 3 Minutes when tested to SAE J343
- Approved by USMSHA ( Fire resistance ) for the use in mines.
- Tested to ISO 8031 for electrical conductivity (anti-static)
- Melting point 225 degrees C +/- 10 degrees C
Features
- Offers High Abrasion Resistance.
- DAS can assist in reducing the dangers of hose leaks or pinhole failure.
- MSHA Approval
Important Safety NoteDiffusion Abrasion Sleeve (DAS) is a diffusion device and conditionally a burst suppression device
NotesLight crimping of the sleeve to the ferrule using a stainless steel 'DAS Ring' is also recommended. Consult Pirtek for the applicable crimp dimensions
Temperature Range-60 degrees C to 125 degrees C
