Canusa SuperCase TM System
• Over a million joints successfully coated
• Traditionally, Canusa has supplied two versions:
Type CSC
▪
▪
Canusa SuperCase, type CSC:
1. Edge Recovery/Sealing
2. Pressure Testing as per EN 489
3. PU Foam Injection into Applied Casing
Canusa SuperCase, type CSC-X:
1. PU foam applied using a removable mould
2. PU foam Inspection
3. Fully Shrinkable CSC-X (and Shrink Film for Double Seal)
Applied over Foam
Type CSC-X

Traditional Crosslinked Joint Casing Systems
• Traditionally, crosslinked PE sheet materials were limited to relatively
low thickness and to standard PE raw material grades
– Due to challenges with irradiation and expansion process
– This also allowed the material to be easily wrapped and handled.
• Thicker, pressure testable crosslinked joint casings have therefore
typically been manufactured by bonding thin layers of crosslinked
HDPE material on a mandrel inside an oven to get desired thickness
• This ‘batch’ process is slower, less efficient and more expensive.

Next Generation Crosslinked Joint Casing System
• In 2009-10, Canusa-CPS invested and developed next generation
extrusion, irradiation and expansion equipment and techniques
• Allowed for centralized manufacturing of thicker, advanced multilayered
crosslinked HDPE materials
• Formed basis for development of next generation of crosslinked joint
casings
• Provides leading edge performance with lower cost to end user

Introducing… Canusa SuperCase TM , type CSC-XP

Canusa SuperCase TM , type CSC-XP
• HybridPEX TM Technology
• Advanced Sealing Performance
• Efficient Design / Manufacturing
• Strongest Resistance to Soil Stress
• Fastest Installation
• Flexible Installation

Canusa SuperCase TM , type CSC-XP
• HybridPEX TM Technology
▪
Rugged, rigid and crack resistant bimodal
HDPE meeting EN 253 standards
(same rating as mainline HDPE jacket)
▪
Crosslinked on the outside
▪ Faster application, improved productivity
▪ Resists premature shrinking
▪ Maintains long term tightness and seal
▪
Uncrosslinked on the inside
▪ Maximum adhesion, weldability and
compatibility
Offering the best of crosslinked
and uncrosslinked casings!

Canusa SuperCase TM , type CSC-XP
• Advanced Adhesive Technology
▪
Minimum preheats for more consistent
installation and speed
▪
Highest shear strength for maximum
resistance to forces associated with preinsulated
pipelines
▪
Proven long term resistance to water
immersion

Canusa SuperCase TM , type CSC-XP
• Efficient Design / Manufacturing
HybridPEX TM Sheet Cut to Length
Sheet Bonded When Required
Casing Ready with Short Lead Time
▪
▪
▪
▪
Bulk sheet supplied from Canusa-CPS manufacturing facility with built-in consistency/quality
No need to bond layers of thin sheet using ovens (inconsistent, slow batch process)
Allows for short lead times (casings made quickly upon order receipt)
Results in lower installed cost for end user

Canusa SuperCase TM , type CSC-XP
• Strongest Resistance to Soil Stress
▪
▪
Advanced adhesive and crosslinked bimodal HDPE
materials maximize rigidity and shear strength
Easily meets EN 489:2009 and even much more severe
requirements for soil stress resistance
Prior to Testing
After Soil Stress Test
FFI (Hanover) Sandbox Testing
EN 489:2009 test with increased requirements of 3m simulated sand overfill, 300
cycles on PE 450 and PE 225 sized pipe samples

CSC-XP 450-750 in Sandbox

Casing Completely Intact at Edges
(Both Top and Bottom and on Each Side)

Absolute No Moisture Ingress
(At any Point on All Samples)
PE 450 Size – 12:00 PE 450 Size – 6:00
PE 225 Size – 12:00 PE 225 Size – 6:00

Canusa SuperCase TM , type CSC-XP
• Fastest Installation
▪
Outer crosslinked bimodal HDPE allowing for
fastest material response time
▪
Low preheat adhesive reduces installation
time and improves consistency
▪
No requirement for additional shrink collars
on the edges to meet requirements for soil
stress resistance

Canusa SuperCase TM , type CSC-XP
• Flexible Installation
Seal, Pressure Test, Then Foam
1. Seal Edges then Foam (Pressure Testable)
▪ Casing is applied (edges recovered)
▪ Then pressure-tested
▪ Then PU foam is injected into the cavity
OR
2. Foam then Apply Casing (Fully Shrinkable)
▪ PU foam is applied first using a removable mould
▪ The PU foam can then be fully inspected
▪ Then the full-shrinkable casing is applied over the foam
Foam, Inspect, then Seal
