European Piling

Product Introduction.

European piling EN10219 Steel pipe piles are designed to transfer structural loads through the foundation to soils below. Pipe piles are most efficient as friction piles. Pipe piles have substantial surface area that interacts with the surrounding soil to provide great frictional load resistance. Pipe piles are also used in conjunction with sheet piles to add lateral stiffness and bending resistance where loads exceed the capacity of sheet piles alone.

EN10219 is a popular producing standard for steel pipe piling, cold formed welded structural hollow sections of non-alloy and fine grain steels.

a The deoxidation method is designated as follows:

FF: Fully killed steel containing nitrogen binding elements in amounts sufficient to bind available nitrogen (e.g. min. 0,020 % total Al or 0,015 % soluble Al).

b The maximum value for nitrogen does not apply if the chemical composition shows a minimum total Al content of 0,020 % with a minimum Al/N ratio of 2:1, or if sufficient other N-binding elements are present. The N-binding elements shall be recorded in the Inspection Document.

1 The impact properties are verified only when Option 1.3 is specified.

2 For thicknesses > 3 mm and section sizes D/T < 15 (round) and (B+H)/2T < 12,5 (square and rectangular) the minimum elongation is

reduced by 2. For thicknesses ≤ 3 mm the minimum value for elongation is 17 %.

3 For section sizes D/T < 15 (circular) and (B+H)/2T < 12,5 (square and rectangular) the minimum elongation is reduced by 2.

4 For thicknesses < 3 mm see 9.2.2.

5 For impact properties for reduced section test pieces see 6.7.2.

6 This value corresponds to 27J at &ndash;30 °C (see EN 1993-1-1).

Description:

BSW provides spiral welded pipe pile in a wide range of sizes and lengths to meet your requirements. In addition, BSW provides value added services such as coating and welding to facilitate complete pipe pile solutions.

For non-alloy steel hollow sections the steel designation consists of:

- the number of this European Standard (EN 10219-1);

- the capital letter S for structural steel;

- the indication of the minimum specified yield strength for thicknesses ≤16 mm expressed in MPa1);

- the capital letters JR for the qualities with specified impact properties at room temperature, the characters for the qualities with specified impact properties at 0 °C and the characters J2 or K2 for the qualities with specified impact properties at -20 °C;

- the capital letter H to indicate hollow sections.

For fine grain steel structural hollow sections the steel designation consists of:

- the number of this European Standard (EN 10219-1);

- the capital letter S for structural steel;

- the indication of the minimum specified yield strength for thicknesses ≤ 16 mm expressed in MPa;

- the capital letter N to indicate normalized or normalized rolled feedstock material or the capital letter M to indicate thermomechanically rolled feedstock material (see 6.3);

- the capital letter L for the qualities with specified impact properties at -50 °C;

- the capital letter H to indicate hollow sections.
