CANMET
Materials Technology Laboratory provides research and consulting services
to industry, with emphasis on pipelines, pressure vessels and power
generation equipment. The overall program objectives are to:
- improve
the reliability for service of Canadian oil and gas pipelines,
marine offshore structures and ships, pressure vessels and power
generation plants, thereby ensuring public safety and environmental
protection;
- enhance
the economic position, security of supply and deliverability of
Canadian energy resources;
- maximize
benefits to the economy from fabrication and service of steel
structures.
The Infrastructure
Reliability Program can help clients in areas such as:
- corrosion
control
- defect assessment
- engineering
critical assessment (ECA)
- erosion/corrosion
of materials for power generation plants
- evaluation
of corrosion inhibitors
- failure
analysis
- fatigue
- fracture
control
- fracture
resistance of welded joints
- hydrogen
cold cracking
- hydrogen-induced
cracking
- marine corrosion
- measurement
of mechanical properties
- non-destructive
inspection
- oil corrosivity
assessment
- repair welding
- residual
stress measurement
- stress analysis
- stress-corrosion
cracking studies
- weld metal
and heat-affected zone microstructure and properties
- welding
of high-strength structural steels
Some of our specific
capabilities include:
- assessing
resistance to stress-corrosion cracking in full-scale and conventional
small-scale pipe tests
- characterizing
aqueous and non-aqueous corrosion behaviour, including measurements
in high-temperature, high-pressure autoclave experiments
- evaluating
hydrogen-induced cracking using ring ovalization tests and
 saturated
solutions
- fatigue
testing of welded joints and assessment of weld improvement techniques
- measuring
non-destructively the surface stresses of engineering structures
using a portable X-ray stress diffractometer
- numerical
modeling (finite and boundary element methods) for stress analysis
and fracture mechanics
- predicting
the lifetime of engineered structures
- welding
and physical simulation of weldability of a variety of materials
using up-to-date welding equipment and a Gleeble 2000 thermomechanical
simulator
