Sample tensile test method (TTT), the cantilever beam method of testing etc. of bend specimen.These methods have one jointly
Feature need exactly to cut out by small sample from steel pipe body or weld seam exemplary position, residing for sample should
Power state can occur bigger change with the stress state residing for steel pipe, is also to affect pipe line steel to resist due to structural agent
One of principal element of corrosive nature, and said method does not accounts for structural agent (concentrated stress) antagonism
The impact of corrosive nature, therefore obtained by these methods, the test result suitability under true service state needs
Consider.
