EN10217-5 Welded steel tubes for pressure purposes - Technical
delivery conditions -
Part 5: Submerged arc welded non-alloy and alloy steel tubes with
specified elevated temperature properties
Material:
Fully killed steel, Fine grain steel with a ferritic grain size.
Steel Names:
In accordance with EN10027-1 and CR10260
Manufacture:
HFW High frequency welded
SAW Submerged arc welded - longiditudinal seam - SAWH
- helical seam - SAWL
Welding Procedure:
Testing and inspection of the welding procedure for submerged ard
welded(SAW) tubes are witnessed and approved in accordance with
EN10217-1
Apperance and General:
The weld areas are free from cracks, lack of fusion and lack of
penetration
The tubes are free from external surface defects that can be
detected by visual examination.
Leak-tigthtness:
The Tubes shall pass a hydrostatic test or electromagnetic test for leak-tightness
Non-Destructive Testing:
The full length of the weld seam of all EW and BW tubes ahll be subjected to a Non-Destructive test for detection of longitudinal imferfections
The full length of the weld seaml of all SAW tubes shall be subjuected to a Non-Destructive test for the detection of imperfections.
Straightness:
The deviation from straightness, of any tube length L, shall not exceed 0.0015L.
Deviations from Straightness over any one meter length shall not exeed 3mm.
Preparation of ends:
Tubes shall be delivered with square cut ends. The ends shall be free from excessive burrs.
