Part 6:   Submerged arc welded non-alloy steel tubes with specified low
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.

 

Testing and inspection of the welding procedure for submerged arc welded (SAW) tubes in accordance with EN10217-1AnnexA
