EN 10217-1 P265TR2 carbon steel welded tubes tolerances
EN 10217-1 P265TR2 carbon steel welded tubes are intended for use in systems for both pressure equipment and pipelines. It is mainly used in boiler, transportation of oil, natural gas, gas, pressure pipe, pipe for ship, structure pipe etc. The alphanumeric TR2 is for qualities with specified aluminum element, impact properties and specific inspection and testing requirements.
The range of T wall thicknesses available for each diameter is very wide. On all of them, the allowable tolerance for Series 1 (the only series for which standardized accessories are available) is reflected in the table below:

P265TR2 tubes outside diameter tolerances
In this EN10217-1 standard, the available length and the allowable differences about lengths appear in the following table:
|
Length L (mm) |
Tolerance (mm) for outside diameter |
|
L < 6000 |
0/+10 |
|
6000 < L < 12000 |
0/+15 |
The total deviation on the straightness of a tube L length (shaft) must not exceed in mm the formula: 0.0015 x L, being L the length supplied by the manufacturer. The deviations of straightness above any length of a meter, must not exceed, in any case 3 mm.
The tolerance for the oval defect is included in the diameter tolerance.
