Prevent Mechanical Failure Due to Non-Specified Materials
The American Petroleum Institute (API) and other industry associations have issued recommended practices for material verification. These positive material identification (PMI)-related practices are intended to help chemical, oil and gas producers prevent a mechanical or system failure related to the use of non-specified materials, which could lead to a release of potentially hazardous or polluting substances. For these reasons, a material verification program that conforms with API-recommended practices is an essential aspect in most quality assurance programs.
PMI testing and evaluation techniques are widely used as part of quality control programs in petrochemical facilities, power generation plants and steel and iron foundries. PMI techniques generally provide a cost-effective method for sampling large volumes of materials during the manufacturing process or on-site. In addition, results are immediately available, allowing for the efficient identification of non-conforming materials.
TÜV SÜD Chemical, Oil and Gas offer material verification programs and services that meet or exceed the requirements of the refining, petrochemical and energy industries as well as API-recommended practices. Our PMI specialist utilize the most advanced technologies to conduct both qualitative and quantitative material verification, including x-ray fluorescence (XRF) and optical emission spectroscopy (OES). These technologies literally bring the metallurgical laboratory into the field to verify the quality of base components and joining materials such as welding, bolting and gaskets.
TÜV SÜD PMI testing and assessment services include:
In addition to these services, TÜV SÜD also offers material verification programs that meetthe current versions of API RP 578 and other relevant standards, as well asconsultation for material verification and PMI programs. Finally, our PMI specialists can qualify and train XRF and OES operators for routine in-house assessments and verification.
