Pipeline Properties
This is the maximum pressure a pipeline is designed to safely operate at.
What is MOP/MAOP (Maximum Operating Pressure)?
This land use type describes areas of water-saturated ground with moss and peat.
What is Muskeg?
This soil condition poses the highest corrosion risk due to low resistivity.
What is Clay?
Electrochemical corrosion requires three components: an anode, cathode, and this.
What is an Electrolyte (Water)?
The number of days technicians have to submit their integrity reports for review after inspection end.
What is 7?
This classification is assessed in a zone extending 1.6km in length and 200 metres on either side of the pipe centreline.
What is Location Class?
This physiographic region includes Alberta’s flat, open lands.
What is the Interior Plains?
Coarse fragments between 2mm and 75mm in size.
What is Gravel?
Most used from 1940 to 1982, this coating type may contain asbestos.
What is Coal Tar Enamel?
This is the required photo size for uploaded dig photos.
What is 16:9?
This steel property indicates the stress level at which it begins to deform.
What is Yield Strength (Grade)?
This term refers to the topmost part of a slope or hill in site positioning.
What is the Crest?
This method is used to measure soil resistivity.
What is the Wenner Four-Probe method? (Pin method)
The coating condition if the section of coating is found to be 35% disbanded.
What is Fair?
The number of days technicians have to submit corrections once their integrity reports have been reviewed.
What is 5?
This factor adjusts allowable stress based on pipeline location and product.
What is the Design Factor?
This topographic location has a straight slope between convex and concave sections.
What is Middle Slope?
This parent soil material is deposited by gravity and found near slopes.
What is Colluvium?
This coating can be applied in the field or during pipeline construction by hand or spray method.
What is Epoxy?
Gouges are reported on this tab in the integrity report.
What is Metal Loss - Manual?
SMYS is an acronym for this, expressed as pressure and calculated using Barlow’s Formula.
What is Specific Minimum Yield Strength?
Forests comprising broad-leaved trees and shrubs that lose their leaves in the fall.
What is Deciduous?
An ohm-cm reading between 1,000,000 and 2,000,000 suggests this type of material.
What is Solid Rock?
This corrosion deposit forms when carbonic acid reacts with the iron of the pipeline and often changes colour from white to beige once exposed to oxygen.
What is Iron Carbonate (FeCO3)?
This document is completed after the PI Report and compares the ILI vendors findings with Tilt’s findings.
What is Correlation?
