Tests we apply to the tubes:

1) Chemical Composition Analysis

2) Mechanical Properties (Tensile

strength, Yield strength,, Elongation,

Hardness)

3) Technological Test (Flattening test,

Flaring Test, Bending Test, Hydraulic

pressure test)

4) Surface quality detection

5) Eddy-current examination

6) Visual test

Packing: Bare packing/bundle

packing/crate packing/wooden

protection at the both sides of tubes

and suitably protected for sea worthly

delivery or as requested.

Surface treatment: Oiled, black

painted, Black Phosphated coating as

required.

Both ends of each crate will indicate the order no., heat no., dimensions, weight and

bundles or as requested.

Third Party inspection is acceptable. such as SGS, BV etc.
