Abrasion Resistant Hose
The abrasion resistant hose is a kind of conveying hoses and is designed for conveying materials with large friction coefficient, which requires the hoses to have ultra-high abrasion resistance. The inner rubber of hose adopts abrasion-resistant NBR. But the abrasion resistant hose doesn't need to bear high pressure and 12BA can be considered as the high pressure.
- Outer rubber layer: SBR/NR mixed conductive rubber
- Inner rubber layer: NBR highly abrasion resistant rubber
- Reinforcement layer, high-strength woven cords. Duratech abrasion-resistant hoses adopt double layer woven cords.
According to the working conditions, the abrasion level of transporting particles caused to the hoses, the abrasion-resistant hoses can be divided into light-weight abrasion resistant hose, heavy-duty abrasion resistant hose and vacuum abrasion resistant hose.
Light-weight abrasion resistant hose
Widely used in applications like sand blasting. Inner rubber adopts abrasion resistant NBR and outer layer is covered by compound rubber.
Heavy-duty abrasion resistant hose
Ideal for sand, grit, grait and slurry blasting equipment.
Vacuum abrasion resistant hose
Embedded spiral steel wires. Vacuum negative pressure up to 0.9BA.
