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.
