SPARK OPTICAL EMISSION SPECTROSCOPY (OES)

FOR MORE INFORMATION

SERVICES

MMT provides field personnel equipped to complete any on-site job, including in-ditch testing of pipelines.


MMT’s field services include:



  • Hardness, Strength, and Ductility (HSD) Tester - A portable, nondestructive testing instrument that measures yield strength, ultimate tensile strength, strain hardening behavior, and identifies seam type.
  • Spark Optical Emission Spectrometry (OES) - NDT measurement of the chemical composition of metal.
  • Metallographic Analysis - Surface etching and acetate replicas are used to characterize the grain structure.


The combination of these services allows our team to deliver complete and accurate reports regarding the mechanical integrity of existing materials or quality control of new manufacturing.

We have the capability to apply our services for applications that include pressure vessels, assembled structures, and aluminum materials. Our team is flexible and capable for meeting the demands of special projects. Before a project, we request at least 1 week of advance notice to accommodate personnel and resources. Generally, a complete report will be provided within 1-2 weeks of the completion of testing, but we will make an effort to accommodate urgent deadlines.

SURFACE REPLICAS

HARDNESS, STRENGTH, & DUCTILITY TESTER

Surface replicas provide an impression of the metallographic grain structure for a metallic material. MMT fully polishes the surface then uses Nital etch and acetate film to collect replicas. These replicas are then analyzed through our software to determine the grain sizes and pearlite content which is ultimately used to enhance the accuracy of our HSD predictions.

ACCURATE AND RELIABLE IN-SITU METAL STRENGTH VERIFICATION

"The PMI-MASTER Smart is a breakthrough for Optical Emission Spectroscopy (OES) analysis in hard to reach places. This robust spectrometer is designed for the precise analysis of key elements, rapid material verification, positive material identification, and metal sorting."

The Hardness, Strength, and Ductility (HSD) Tester is a portable, nondestructive testing (NDT) instrument for metals that accurately and reliably measures the yield strength and identifies the longitudinal welded seam type of pipelines without service interruption or expensive cutouts.

FOR MORE INFORMATION

​​Massachusetts Materials Technologies (MMT) offers fast and reliable field testing services to determine the strength properties of steel and to characterize the longitudinal welded seams of pipelines without service interruption or expensive cutouts. Data from this non-destructive testing will prove very valuable for the industry and can be used to identify the steel grade and differentiate between fabrication processes. MMT has performed in-ditch testing across the United States and in Canada. Our performance has been benchmarked through four rounds of blind testing validation, and in-house accuracy and repeatability metrics are provided in the resources below.

NONDESTRUCTIVE TESTING (NDT)

FULL DATA SERVICE

Standard test method for Hardness, Strength, and Ductility testing of metallic materials for tensile strength properties.

ADDTIONAL MMT SERVICE INFORMATION

This document summarizes the accuracy and repeatability of the HSD Tester, with respect to the prediction of the yield strength and ultimate tensile strength (UTS). Accuracy is defined as the difference between HSD Tester predictions and tensile test measurements for the same metallic material. Repeatability is the ability of the HSD Tester to produce the same measurements on the same sample over time.
