In many parts of the U.S. and other countries, civil infrastructure is aging. This infrastructure could benefit from periodic investigation of the residual stresses present in it.
For transport infrastructure such as pipelines, residual stress can be just as important to the intended purpose. Using x-ray diffraction to determine the total surface stresses in bridges can enable measurement of dead loads in bridge support members, which must conform to design specification for safe use.
Pipelines are susceptible to failure due to complications from welding stresses and phenomena such as stress corrosion cracking. By keeping track of internal stresses, the effects of harmful stresses can be mitigated.
Material Testing’s nondestructive techniques can quickly and easily provide a direct measurement of the residual stress state of a variety of components where it may be of concern, all without disrupting operation and in accordance with ASTM E915, ASTM E2860 and SAE HS-784.Request a Quote
