5 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 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

6 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.

7 Next Generation Crosslinked Joint Casing System In , 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

8 Introducing Canusa SuperCase TM, type CSC-XP

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

10 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!

11 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

12 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

13 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

14 CSC-XP in Sandbox

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

16 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

17 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

18 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
