What should you look for in a coating inspection of an exposed pipeline?
To identify disbonded coating, look for coatings that are peeling, flaking, wrinkling, separated from the pipeline, or have an asymmetrical look.
What is pipeline coating?
A pipeline coating is a cost effective and viable solution to maintain pipelines’ integrity. This coating provides a constant protective lining that helps save pipelines from the damaging effects of corrosion. Pipeline coating is one of the most reliable corrosion prevention methods used by industries today.
What is Yellow Jacket pipe coating?
Yellow Jacket® is a two layer external coating that provides protection for pipelines used in the oil and gas and waterworks industries requiring up to moderate operating temperatures and good handling capabilities.
What is YJ2K coating?
YJ2K™ is a bonded coating system consisting of a Fusion Bond Epoxy primer, copolymeric adhesive and a cross-head extruded high density polyethylene outer layer.
What is stringing in pipeline?
Stringing is the delivery and aligning of the pipe joints along the side of the pipeline trench ready to be welded and tested before being lowered into the trench. Each joint of pipe has a specific place in the pipeline.
What is a pipeline pi?
P.I. Point of intersect where the direction of the pipeline changes and is usually identified by lathe or. wooden stake in the ground.
What is the process of pipe coating?
In general, the coating process includes: heating the pipe, the coating application and curing/cooling of the coated pipes. For each process, we can build equipment suitable for a wide range of pipe diameters and lengths.
How many types of pipe coating are there?
However, for the sake of this article, prediminanently there are following types of external anti-corrosion coatings: Fusion Bonded Epoxy (FBE) Coating. Three Layer Poly Ethylene/ Propylene (3LPE/ 3LPP) Coating. Coal Tar Enamel (CTE) Coating.
What are steel pipes coated with?
Three Layer Polyethylene or Polypropylene coating to DIN 30 670. Buried pipelines are often exposed to extremely high stresses under service conditions. Efficient corrosion protection, therefore, is an essential pre-requisite in maintaining their trouble-free operation.
What is pipeline installation?
In the S-lay method, single lengths of steel pipe (joints) are welded, inspected and coated in a horizontal working plane (firing line) on board a pipelay vessel. As the vessel moves forward, the pipe gradually exits the firing line, curving downward through the water until it reaches the touchdown point on the seabed.
What is the average salary of a pipeliner?

What is mainline pipeline?
The Mainline is Canada’s largest crude oil transportation system and plays a critical role in providing safe and reliable energy supply for North American consumers. Other Enbridge market access pipelines serve markets in the U.S. Gulf Coast, Oklahoma, southern Illinois, and Quebec.
What are the standard coatings for oil and gas pipelines?
Pipeline owners and coatings contractors are both responsible for selecting pipeline coatings that meet the necessary regulations. The minimum surface preparation standard for the oil and gas pipeline body is SP 10 Near-White Blast Cleaning with SP 11 Bare Metal Power Tool Cleaning for the ends of the pipeline where the joint coatings are applied.
Where are the Shaw pipe coatings located in Canada?
Camrose, AB, and one in Regina, SK, Shaw Pipe’s facilities are strategically located to serve the growth in the Oil Sands region and theWesternCanadianSedimentaryBasin. Shaw Pipe is part of Bredero Shaw, the global leader in pipe coating solutions and employs approximately 4,000 employees located at offices and facilities in fifteen countries.
How are joint coatings different from cathodic protection?
Joint coatings are field-applied with the same coating system as the body of the pipeline. Cathodic protection isn’t used on the above-ground sections of the pipeline. Though seemingly different from buried pipeline systems, underwater pipelines are actually in quite a similar environment, as they are both immersive.
Why do oil and gas pipelines need to be pre cast?
One additional element that’s added to underwater pipelines is concrete weight coatings — some poured and laid on site, some pre-cast — to ensure the pipeline stays at the desired depth and doesn’t float out of the water. As with the exterior of most pipelines, corrosion is a risk factor for the interior of oil and gas pipelines.
