Acceptance Tests and Certificates:

We will supply the purchaser with individual test certificates for each finished hose,or certificates issued by a third member association of IACS-Internationa Association of Classification Societies including China(CCS),Norway-German(DNV-GL) and France(BV).

The following tests are to be conducted:

- Material tests(one order at a time)

- Adhesion tests – hose body and,if applicable,buoyancy material(one order at a time)

- Weight test(each hose)

- Minimum bend radius test(before hydrostatic pressure test,10% sampling)

- Bending stiffness test(10% sampling)

- Torsion test(if specified)

- Tensile test(if specified)

- Hydrostatic pressure test(each hose)

- Vacuum test(immediately after kero test.if not kero test,then immediately after hydrostatic test,each hose)

- Electrical test(each hose)

- Float hydrostatic test(only for floating hose,one order at a time)

- Lifting lug acceptance test(only for tank rail hose)

 

Hose Lifting Instruction

At least 3 point lifting is required, 5 point lifting is more favorable.
