  HOSE HANDLING GUIDE  
Our composite hoses are designed to ensure the highest levels of reliability, durability and safety but, to maintain these levels, regular inspection, cleaning and testing are essential.
  INSPECTION  
Worn or damaged hoses may be dangerous, so they should be visually checked before each operation and given a more rigorous examination at least every six months. The inspection should pay attention to:
1- Dents or kinks.
2- Displacement of inner and outer reinforcing wires from their normal pitch.
3- Corrosion or abrasion of the outer wire.
4- Displacement of end fittings or signs of leakage from the ends.
5- Other abnormal features including wear or damage to end fittings.
6- Chemical attack. Deterioration or physical damage to outer cover and carcass generally.
Hoses with any significant defects of the above type should be retired from service. Moderate abrasion of the outer cover is acceptable if the reinforcing fabrics below the cover are undamaged.
  CLEANING  
Hoses should be cleaned after use and always before testing or prolonged storage . The most appropriate method will depend on the hose use and its location.
Flushing out is often sufficient with fluids such as clean water , hot water , detergents, common solvents at ambient temperatures and sea-water. if sea-water is used, it must be thoroughly drained afterwards to minimize risk of corrosion on carbon steel end fitting or galvanized steel internal wires.
It is essential that any strong acid convey ants are thoroughly drained prior to cleaning, to avoid exothermic creation. It is also important to fully drain the hose afterwards to ensure puddles of cleaning fluid are not left within the assembly. This avoids any possibility of chemical reaction when the hose re-enters service.
Lose steam may be used but the hose must be open-ended and its maximum working temperature must not exceeded, since damage to the fabric or film may occur. Compressed air may be used, but again the hose must be open-ended.
During cleaning the hose must be electrically earthed it avoid static charge build-up especially near flammable areas. Pigging must not be used under any circumstances.
  TESTING  
At least annually, hose should be hydraulically tested as follows.

1- Drain and thoroughly clean hose and check end-to-end electrical continuity.
2- Inspect visually. Hoses failing visual inspection should not be tested.
3- Lay hose straight out on supports or roller bed that allows free movement under pressure.
4- Blank off ends and fill the hose completely with water. Ensure trapped air is released by tilting slightly.
5- Pressurize the assembly to 1.5 times the maximum rated working pressure for 10 minutes while examining for leaks. Also test electrical between ends to ensure that it is the same as initially checked.
6- Release pressure and drain hose.
7- On completion of the test, the hose should again be tested for electrical continuity.

It should be noted that with thermoplastic composite hose, elongation under pressure can be high relative to rubber. This is a feature of composite hoses and unlike rubber hoses. It cannot be taken as an indication of failure or used to assess the condition of the hose reinforcements.
  ELECTRICAL CONTINUITY TESTS  
To prevent the accumulation of static charge generated in use, all metal parts of the assembly have been electrically bonded during manufacture. At intervals not exceeding six months, the following test should be carried out.
1- Lay hose flat on the ground.
2- Check that it is electrically continuous end-to-end with a simple battery and bulb test or an ohm meter.
Hose not having electrically continuity should be retired from service.

  HOSE HANDLING GUIDE  
Our composite hoses are noted for their durability but their life can be determined by how they are used in operation. To ensure maximum service life, follow these simple guidelines.
  ALWAYS  
1- Support hose at appropriate points with slings.
2- Support hose near manifold connections.
3- Support hose against sharp edges such as jetty edges and a ship’s guard rill.
4- Store hose in a straight line raised off the ground, preferably in a cool, dark area.
  NEVER  
1- Use hose unsupported.
2- Support hose with a single rope.
3- Allow hose to drop between ship and jetty.
4- Over bend hose.
