Construction
- Lining: Uniform lining of suitable rubber compound resistant to all grades of petroleum and blended products having aromatic hydrocarbon content not more that 25%
- Reinforcement: Plies of natural synthetic woven fabric rubberized with a suitable compound and two helical GS wires. (as per IS 280/78) embedded in the reinforcement plies in the case of smoothbore and in rough bore hose, the first is internal and the second is embedded.
- Electrical Bonding: A copper wire comprising of a number of strands is embedded between the reinforcement plies to provided electrical continuity along the whole length of the hose.
- Cover: Chloroprene rubber outer cover having plain or corrugated cloth marked finish, resistant to oil abrasion and weather.
- End connections: The hose has built-in nipples with or without flanges as per the customer’s specification. I-D (mm) Max Length (meters) Up to 100: 15.00/ Up to 200: 9.0/ above 200:7.5
- Temperature Range: 400 F to + 200 0F
