Discussion, question & answers
5 16 May 2011 Presentation title
Criteria for the selection of coatings • Coating materials are often selected acc. to the Operating temperature given in the specification BUT:
• ISO21809-1 definition of Design temperature includes more: “ Temperature range including maximum and minimum temperature likely to be reached during transport, handling, installation and operation “ Operating temperature 0° to +60°C Pipe storage temperature -10°C to +70°C Transportation temperature -20°C to +60°C Installation temperature -5°C to +70°C

Design temperature for coating 6 16 May 2011 Presentation title
Transportation criteria to be considered for the selection of coatings • Temperature conditions • Weather conditions (intensive sun radiation) Surface of black coating can get to 65°C-70°C in the sun • Distance to destination • Expected quality of transportation Road conditions • Type of pipe supports used soft/hard Point loads/ surface loads •Number of re-loadings •Specific meter weight of pipe © 2008 Borealis AG

Point load, surface load combined with friction, vibration, temperature 8 16 May 2011 Presentation title
Storage criteria of coated pipes Often pipes are stored for longer periods at
• the coaters yard • Intermediate storage, like harbour etc • Project installation site
Conditions be considered: • Duration of storage under high UV radiation, maybe protection needed
• High and low temperature
• Limitations to handle at certain temperatures
• Dry/wet conditions and time >> i.e. cut back protection needed?
• Type of pipe supports © 2008 Borealis AG
• Support wood , gravel or sand

Installation & Handling criteria for coatings
Potential damages are caused by: • Pipe lifting on and off from truck
• Welded pipe positioned via rollers • Access to trench • Available quality of lifting devices • Pipe bending operation
© 2008 Borealis AG
• Quality of sand bedding around the pipe • Availability of fine sand • Quality of sieved backfill
Pictures courtesy of Europipe MPC 10 16 May 2011 Presentation title
Specific weight of the pipe • All pipes without additional concrete outer coating require a high level of sand-bedding quality around the pipe • Proper compaction of the backfill • Stone free zone around the pipe
• Water • Oil • Chemicals Risk of Stone

Mechanical Requirements for PE Topcoat
Hot climate pipe coating needs • Pipelines being installed in hot climates • More construction activities in remote and difficult terrain: •
Long transportation distances and harsh pipe handling
• •
Access for crews and big equipment Big pipe stocks and long storage under sun light
• Higher outside and operating temperatures • Installation techniques are limited:
© 2008 Borealis AG
• • •
Access to enough material for sand-bedding Sieving of soil achieves only coarse backfill Limited access to open trench from one side means pulling the pipe via rollers into final position
Tailored Bimodal HDPE - for hot climates recommended (Borealis & Borouge sourced)

16 May 2011 Presentation title
Some remarks from a resin manufacturer • Operating temperature is not the only design criteria! • Engineering and pipeline designers should involve us earlier • We can at least give some recommendation and share views • Reference projects might help to decide for the right system • Draft specifications could be exchanged prior to publication • There are PE and PP systems for all applications, just the right choice decides!
© 2008 Borealis AG
• When specifying the coating, think about the field joint solution!

• Offshore does not directly mean PP coating....! • Directional drilling can also be performed with bimodal HDPE, class B3 with higher coating thickness 22 16 May 2011 Presentation title
Class B MDPE/HD LDPE PE ≥920kg/m ≥930kg/m Density ³ ³ Tensile strength ≥10N/mm² ≥15N/mm² 23° Vicat soft ≥95°C ≥110°C Shore D ≥45 ≥55 Hardness ESCR 300h 1000h F50 @50°C Indentati on at ≤0,4mm ≤0,4mm max. at 60°C at 80°C operating temp.
The slight increase in coating thickness for LDPE does not compensate!

• Around 20 minutes per joint for 508mm

Borcoat materials for Wehocoat process • System only consists of 2 layers: • Fusion bonded epoxy, powder, spray applied
• Modified PE/PP material (like Borcoat ME3000FC)
• Modified PE or PP is a so called “reactive top coat”, i.e. a top coat with ability to React with the epoxy due to functional groups
Perfectly weld to the factory applied coating Acts as a top coat related to mechanical protection Borcoat ME3000FC could be described as “MDPE” classB acc

Wehocoat – Borcoat™ Conclusions
© 2008 Borealis AG
• Meets tough requirements for coated pipes, >200N/cm at 23°C and >40 N/cm at max operating temp., normally 80°C ( PE ) • ISO21809-1 minimum “Properties of applied coating” are fulfilled as for factory coated steel pipe • Excellent mechanical protection vs. shrinkable sleeves • Fast over all application cycle • Assembling of shrink-sleeves manual work – gas flame application....! • Wehocoat with new Borcoat™ products gives excellent repeatability from joint to joint – no weak links anymore • Life Time Cost savings for pipe line: •Competitive Field Joint Installation cost for projects •Longer life time for the whole pipeline
A chain is as strong as it’s weakest link! 39 Kari Punnonen – 31.1.2010
