Dimensions and tolerances | For the outside diameter D219,1 D +/-0,75 % or +/- 6 mm depending on which value is greater. The tolerances applied to wall thickness depend on the wall T For T5 +/-8 % or 2 mm (depending on which value is greater) |
Pipe lengths | Pipes with precise lengths are manufactured with the following tolerance values: for D406,4- for pipes 0- 6m -0/+25%- for pipes 6-12m -0/+50%- for pipes longer than 12m -0/to be negotiated |
Tightness | Pipes should be subject to water testing (7Mpa) or electromagnetic testing. |
Straightness | < 0,0015 of pipe length (below 3mm per every meter of pipe length) |
Tests | Mandatory tests: ladle analysis, tensile testing, transverse tensile testing of the weld > 508, tightness testing, dimension verification, visual inspection, NDT of the weld Optional tests: transverse tensile testing of the weld D= 219,1- 508, wall thickness measurement at a distance from pipe ends |
