Condition Details:

 

Designation

Symbol

Description

Cold finished (hard)

BK

Tubes do not undergo heat treatment following the final cold forming and, thus, have a rather high resistance to deformation.

Cold finished (soft)

BKW

The final heat treatment is followed by cold drawing involving limited deformation. Appropriate further processing allows a certain degree of cold forming. (e.g. bending, expanding).

Cold finished and stress-relieved

BKS

Heat treatment is applied following the last cold forming process. Subject to appropriate processing conditions, the increase in the residual stresses involved enables both forming and machining to a certain degree.

Annealed

GBK

The last cold forming process is followed by annealing in a controlled atmosphere.

Normalized

NBK

The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere.

 

 

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

Mill test certificates will be issued according to EN10204/3.1B

 

 

Other Terms:

 

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.

Inspection and Test: Chemical Composition Inspection, Mechanical Properties Test(Tensile Strength,Yield Strength, Elongation, Flaring, Flattening, Bending, Hardness, Impact Test), Surface and Dimension Test, No-destructive Test, Hydrostatic Test.

Surface treatment: Oiled, black painted, hot dipped galvanized or phosphate coating as required.

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