Positive Material Identification (PMI)

Fairtex Group offers state of art PMI testing services at site or work spot. Equipment with XRF and OES Technology can be deployed depending on the job requirement. Highly reliable SPECTROTEST-OES technology equipment is deployed for carbon measurement to identify alloys such as low carbon or high carbon stainless steels and other exotic materials.

Positive Material Identification (PMI) is one of the non-destructive testing (NDT) methods used to verify the material supplied is in compliance to the standards and specifications code. Most of our PMI customers are involved in Petrochemical, Oil & Gas Industries, Automotive and Power Generation. PMI is particularly used for high-quality metals like stainless steel and high alloy metals.

How can PMI examination help Oil and Gas industries? The need for materials to be verified at the work-site is highly demanded by customers to ensure it meets standards and requirements. PMI is a portable method offering the best solution to determine or identify the alloy composition of the materials, even as easy as sorting the mix material and not required to sacrifice the sampling item. The American Petroleum Institute (API) requires that such testing is to be done in order to avoid material mix-ups, which can easily result in devastating accidents in the refinery environment.

Fairtex Group offers reliable PMI services both in laboratory and on-site with competent, experienced and well-trained technical expertise. Our operating procedures and practices conform to international standards such as API-RP 578. PMI inspection is commonly used as it is an accurate and fast non-destructive technique for testing pipes, valves, bolts, flanges, rivets, welds, cladding or any other metal components to determine the alloy composition, both in-process and in stock.

We offer two methods for in-situ PMI as follows:

• PMI examination with XRF-machine (X-Ray Fluorescence)


• PMI examination with Arc Spark Emission Spectrography (OES)

• Solutions for power generation plus midstream/downstream oil and gas facilities


• Safely perform material verification when you’re deployed at heights, navigating through a pipe rack, or mobilizing offshore


• Easily analyze corners, joints, and tight welds with lightweight, ergonomic design


• Perform material inspection even when the plant is up and running


• Analyze quickly to maximize sample throughput and productivity


• Position samples confidently and enjoy full-scale imagery with micro and macro cameras


• Quickly replace a depleted battery to continue on-site user operation with hot swap functionality


• Fast, simple reporting and certificate generation


• Get non-technical users up and running with minimal training


• Generate and email analysis certificates in minutes
