Welded Steel Tubes EN10217-1 P195TR1 P235TR1 P265TR1 for Pressure Purposes


EN10217-1 Welded steel tubes for pressure purposes - Technical delivery conditions -
Part 1: Non-alloy steel tubes with specified room temperature properties


Since 2nd century, the welding seam quality increased a lot with fast development of excellent quality steel coil production, welding technology and inspection technology improvement, more welding steel tube sizes are available, and gradually widely used in different areas to replace seamless steel tube.

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

Testing and inspection of the welding procedure for SAW tubes witnessed and approved in accordance with EN10217-1 AnnexA
