Notes:
A cylindrical specimen is 0.2in square(10mm²)
Because its speciality, pipeline steel asks for some requirements in detail, which includes component, carbon equivalent or the sensitivity exponent of weld crack, Drop-Weight Tear Test, V type impact strength and section of shear, cold bend, hardness, banded structure, grain size, impunty,, ultrasonic flaw detection and so on. These requirements could be showed in the contact, technical condition and techincal agreement.
