Pipeline Engineering

Pipeline transportation of fluids requires specific pipeline engineering experience and knowledge to meet safety, quality, and efficiency goals. Our team of qualified stress engineers has extensive understanding of CSA Z662 requirements and specifications for both buried and above ground piping in conjunction with the following fluids: high pressure steam, produced gas, produced emulsion, diluent, hot bitumen, sour gas, sweet gas, CO2, and other liquids. Pi Engineering utilizes a combination of software, expertise, and experience to complete pipeline analysis and offers specialized expertise in:

Pipeline Route Stress Analysis or Bend Studies

Analyze a pipeline route to determine optimal bend radius and technology, eg. Field cold bends versus shop bends or roping.

Pipeline riser

Pipeline Riser Design

  • Riser design and flexibility analysis
  • Addressing tie-in design and pipeline expansion
  • Mitigation methods including loops, offsets, ethafoam boxes and anchor blocks

Vehicle Crossings

  • API 1102 Compliance
  • Custom engineered crossings for non-conventional vehicle traffic
  • Pictured is a simplified 2D representation of an FEA of a Caterpillar 797F Mining Truck crossing a pipeline
  • 3D FEA is also performed in conjunction with hand calculation techniques (API 1102, CEPA, Boussinesq)

A Buried Support

Buckling, Overburden, Buried Support Local Stress

In addition to typical common practice, we, by routine include checks for buried support stresses, global buckling, vehicle crossings, bend thinning, hydrotesting, etc.

Integrity Dig Reviews

  • Stress Analysis
  • Buckling
  • Support
  • Fitness for Service Review of Dents, Gauges, Buckles, Defects
Integrity dig review
Differential Setllement

Differential Settlement

  • Slope Stability
  • Seismic
  • Consolidation

Strain Gauging

  • Monitors Pipeline State from Installation Through Operation
  • Early Warning to Detect Excessive Strains Before They Become an Issue
  • Recommended to Validate Designs Based on Non-Linear Strain Based Criteria
Strain Gauging

Blasting Near Pipelines/Wells

  • Blasting Induced Pipeline Stress/Strain Estimation
  • Peak Ground Speed Estimation
  • Strain Gauging/Monitoring

We have incorporated 50 years of combined experience into our pipeline stress analysis systems. We perform state of the art stress analysis of pipelines, including non-linear materials and non-linear geometry.

We check over 100 items in every pipeline stress analysis we do.
