9 Needs and challenges <strong>of</strong> major industry sectors for future applications<br />
9.4.5 Hot topics<br />
Pipeline construction:<br />
High-strength steel line pipe - Weldability, consumable development (weld metals), full-scale<br />
performance.<br />
More productive/less labour intensive welding processes – Advanced power supplies (advanced<br />
waveforms, etc.), hybrid welding process (laser/GMAW), robotics, vision sensors, adaptive control,<br />
single-shot welding processes, etc.<br />
Advanced methods for pipeline tie-ins – Mechanised single-sided welding, advanced alignment<br />
systems, etc.<br />
Advanced NDT methods – Phased array UT.<br />
Design guidance for pipelines hostile environments – Strain-based design.<br />
Shortage <strong>of</strong> skilled manual pipeline welders – Incentives for young people to pursue welding as a<br />
career.<br />
Pipeline operations:<br />
Pipeline repair and branch connections – In-service welding, new innovative pipeline repair<br />
technologies (composites and other non-welded repair methods).<br />
Mitigation <strong>of</strong> greenhouse gases – In-service repairs and modifications.<br />
Emerging pipeline issues:<br />
Transportation <strong>of</strong> hydrogen by pipeline – Hydrogen embrittlement.<br />
Transportation <strong>of</strong> CO 2<br />
by pipeline.<br />
9.4.6 Emerging technologies<br />
High-strength steel line Pipe: The use <strong>of</strong> higher strength steel requires less wall thickness for a given pipeline<br />
design or higher operating pressures for a pipeline design <strong>of</strong> a given wall thickness.<br />
Hybrid welding process: High efficiency lasers, which are becoming increasingly available, may make the<br />
use <strong>of</strong> hybrid welding processes feasible in the field. These processes are much more productive/less<br />
labour intensive than even the most advanced mechanised welding systems. Seam tracking will be an<br />
integral part <strong>of</strong> this technology since the welding speeds are high.<br />
Phased array UT: Phased array ultrasonic testing (UT) equipment is much more compact, reliable, and<br />
efficient than conventional multi-probe systems. Higher efficiency inspection systems are required to keep<br />
up with high efficiency welding systems.<br />
Innovative pipeline repair technologies: Composites and other non-welded repair methods will continue<br />
to be an attractive alternative to conventional repair methods in the future. The primary advantage <strong>of</strong> these<br />
is that the need for in-service welding is precluded.<br />
9.5 Pressure equipment sector<br />
The pressure equipment industry (PEI) was an integral part <strong>of</strong> the advent <strong>of</strong> modern industrialisation,<br />
and is still one <strong>of</strong> the core industries. Its products, most <strong>of</strong> them <strong>of</strong> welded construction, are essential<br />
components <strong>of</strong> many other branches <strong>of</strong> industry. Its future, therefore, is very much dependant upon the<br />
