The Design Materials & Construction (DMC) Technical Committee focuses research efforts on the development of safe, environmentally responsible, cost-effective, and reliable solutions for the design, construction, and operation of energy pipelines. DMC research enhances the performance of new pipelines through development and implementation of new design methods, materials, and construction technologies.

FEATURED RESEARCH
PR-350-164501-R01
Guidance for Assessing Buried Pipelines After a Ground Movement Event 🖥🌐
The research conducted by Dr. Yong-YI Wang set out to improve pipeline design to better accommodate significant localized ground movement such as that caused by landslides, earthquakes, or subsidence/settlement. When such a ground movement event occurs along the right-of-way (ROW) of a buried pipeline, it is imperative that the pipeline operator determine whether the ground movement is a threat to pipeline integrity in order to protect those responding to the event, those living near the affected ROW, and the environment. This research provides guidance to operators responding to a ground movement event.

Weld Hydrogen Cracking Risk Management Guide 🌐
This report used existing industry research to understand where gaps in knowledge exist related to hydrogen cracking from weldments. Some concepts, identified in this document, are demonstrated to illustrate what can be achieved in support of weld hydrogen cracking management.
PR-631-174506-R01
Substandard Properties in Pipeline Fittings and Flanges 🖥🌐
This research project reviewed instances of high-yield (42-80 ksi) fittings and flanges that occurred over the past few years in Canada and the USA. The main activities in this project included a survey of operators and manufacturers, a few of the scientific literature pertinent to the metallurgy of fittings and flanges, a critical review of the relevant MSS and CSA manufacturing standards, as well as a summary of proposed changes for MSS-SP-44 that have been recommended by API Sub Committee 21 (Materials working group on pipeline flange and fitting quality).
