3.1
employer
organisatlon for which a person works on a regular basis
Note 1 to entry: The employer may be either the tube manufacturer or a third party organization providing services, such as Non-Destructive Testing (NDT).
3.2
EW
electric welded tube
tubular product having one longitudinal seam weld produced by electric (resistance) welding where the strip edges to be welded are mechanically pressed together and the heat for the welding process Is generated by the resistance to flow of low or high frequency electric current applied by either a conduction or induction process
3.3
H FW
high frequency welded tube
EW tube produced specifically using a welding current frequency equal to or greater than 100 kHz
3.4
SAW
submerged-arc welded tube
tubular product having one or two longitudinal seams, or one helical seam, produced using the submerged-arc welding process
3-s
SAWH
submerged-arc helical welded tube
tubular product having one helical weld seam produced using the submerged-arc welding process
3.6
SAWL
submerged-arc longitudinal welded tube
tubular product having one or two longitudinal weld seams produced using the submerged-arc welding process
4 Symbols
For the purposes of this document, the symbols given in EN 10266 apply.
5 Classification and designation
5.1 Classification
In accordance with the classification system in EN 10020. the steel grades in this standard are classified as non-alloy quality steels.
6.3 Example of an order
100 t of HFW steel tube with an outside diameter of 168.3 mm, a wall thickness of 4.5 mm in
accordance with EN 102 17-1. made of steel grade P235TR2 In 6 m random lengths, with a 3.2
inspection certificate in accordance with EN 102O4
loot- HFW-Tube – 168.3 * 4.5- EN 10217-1 – P235TR2 – 6m – Option 9:3.2
7 Manufacturing process
7.1 Steelmaking process
The steelmaking process is at the discretion of the steel or tube manufacturer with the exception that steel produced by the open hearth (Siemens-Martin) process shall not be employed unless in combination with a secondary steelmaking or ladle refining process.
Steel for quality TR2 shall be fully killed and contain nitrogen binding elements, details of which shall be reported.
NOTE This excludes the use of rimming. balanced or semi-killed steel.
7.2 Tube manufacture and delivery conditions
7.2.1 Tube manufacturing shall be as specified in Table 1.
Unless Option I is specified, the manufacturing process and route is at the discretion of the manufacturer.
Option 1: The manufacturing process and/or route from Table 115 specified by the purchaser.
The submerged arc weld of SAW tubes shall be made using at least one weld run on the inside and one weld run on the outside of the tube.
The strip used for the manufacture of SAWH tubes shall have a width of not less than 0,8 times or more than 3,0 times the outside diameter of the tube.
The finished tubes shall not include the welds used to join together the strip or plate prior to forming, except for SAWH tubes where this is permitted only when the welding procedure for the weld joining the strip or plate has been qualified in accordance with Annex A and has also been subjected to the same Inspection and testing regime as the helical pipe welds (see 11.11.4).
7.2.2 Tube production welding shall be carried out by qualified personnel in accordance with documented procedures. For tubes to be used in pressure equipment under European legislation, manufacturers shall employ an established procedure for the approval of welding operatives.BS/EN 10217-1-2019 pdf download.
