DIN EN 10246-7-2005 钢管的无损检验.第7部分:无缝和焊接钢管(埋弧焊除外)纵向缺陷检测用全圆周自动超声波检验
Non-destructive testing of steel tubes - Part 7: Automatic full peripheral ultrasonic testing of seamless and welded (except submerged arc welded) tubes for the detection of longitudinal imperfections; GEnglish version of DIN EN 10246-7:2005
This part of EN 10246 specifies the requirements for automatic full peripheral ultrasonic shear wave (including
phased array technique) and Lamb wave testing of seamless and welded steel tubes, with the exception of
submerged arc-weld (SAW) tubes, for the detection of longitudinal imperfections. This European Standard specifies
acceptance levels and calibration procedures.
This part of EN 10246 is applicable to the inspection of tubes with an outside diameter > 10 mm, and with an
outside diameter-to-thickness ratio _> 5.
For tubes with an outside diameter-to-thickness ratio < 5, one of the options specified in Annex B shall be used by
agreement between purchaser and manufacturer.
The European Standard EN 10246 "Non-destructive testing of steel tubes" comprises the parts shown in Annex A.
