Design capacity of the Mac Kay River Pipeline is 44,000 b/d.
Construction began in October 2000 and was completed by mid of December 2002.
It was necessary to design the pipeline system so that sufficient heat would be retained to enable the pipeline to be shutdown for 2 days and subsequently restarted while carrying blended product.
An assessment of existing material testing procedures wasn’t performed to qualify coating materials.
Mac Kay River Pipeline in Alberta led to development of an innovative coating system.
13.5 Make the sentences negative and interrogative.
Long-term monitoring will likely validate the design and application of the insulated three – layer coating system used on the Mac Kay River Pipeline.
Construction began in September 2001 and was completed by mid October 2001.
Material selection considered pipeline-operating requirements, coating application processes and material costs.
Text 14 Coating Selection
Operational requirements and the environment were key influences on the final design of the coating system.
Thermal insulation was necessary to meet the heat-retention requirement needed to maintain the pump ability of dry bitumen even after a 2-day shutdown.
Polyurethane foam's relatively low mechanical strength made an external jacket essential. The jacket had to be robust and water-resistant to withstand the demands of the environment, consisting of clay soil, muskeg, and directional drill sections. In addition, the possibility of a failure of the shop-applied coating or the field-applied joint coating drove the requirement that the anticorrosion barrier be suited to immersion service at elevated temperatures. All factors led to selection of an insulated three-layer coating system.
Historically, there have been similar insulated three-layer coating systems ed around the world to transport fuel oils, sulfur, and sour gas. In Europe, district heating systems using an insulated three-layer coating system are quite common.
Insulated coating systems are also available for onshore and subsea pipeline applications. The operating temperatures of most insulated pipelines in North America are less than 110°C.
There were relatively few options for the anticorrosion layer, given that it must be able to withstand immersion conditions up to 130°C.
Three-layer polyolefin coating systems, one of the most robust coating systems available for immersion service, consist of fusion-bonded epoxy (FBE) primer, adhesive, and extruded polyolefin (Coating System B of CSA Z24S.21-98).
Typically, these systems are limited to operating temperatures of less than 85° C. for polyethylene (PE)-and 110° C. for polypropylene (PP), although some PP systems are rated considerably higher. PE tapes have been used for insulated pipelines operating up to 95° C.
Common high-temperature FBE coatings are frequently designed for use as a primer coat in multilayer coating systems; however, they are rated for high operating temperatures in dry conditions only. A standalone, high-temperature FBE coating, which had just become commercially available, was used as the anti-corrosion layer of choice for the MacKay River Pipeline.
A spray-applied polyurethane foam based on a European district heating-approved product was selected as the insulation for the MacKay River Pipeline. This foam has a well-documented service history at high temperatures similar to project requirements. The foam system used on the European District Heating systems is mold-injected. Foam insulation is normally spray-applied in North America; thus some modification of the foam was necessary to speed up the curing process.
The foam thickness and thermal conductivity were selected to meet the operational requirement for an unblended shutdown window of 2 days.
This insulation thickness corresponded to an outer jacket temperature of 60° C.
Extruded PE is a relatively low-cost material with excellent properties including water resistance, toughness, impact resistance, and strength.
As a result, extruded PE has become an industry standard for protecting foam insulation.
Outer jackets consist of extruded PE with the option of a PE tape inner wrap between the foam insulation and the extruded PE.
The PE tape inner wrap tends to improve the impact and handling resistance of the outer jacket. The PE tape is either joined to the extruded PE outer jacket with an adhesive layer or by way of heat fusion.
A range of PE types is available for extrusion from low-density PE to high-density PE. The latter (HDPE) has the highest tensile strength and hardness of all extruded PE coatings and is the material of choice except for winter construction with temperatures dipping lower than -30° C, at which point the impact resistance and elongation at break decrease significantly.
At ambient temperatures of—40° C, HDPE may crack when subjected to moderate impacts or pipe movement. As such, low or medium-density PE is recommended for winter construction.
Since the MacKay River Pipeline was scheduled for late summer or early fall construction, an outer jacket consisting of a PE tape inner wrap heat-fused to extruded HDPE was chosen.
