CORE Liner® is a pipe-in-pipe system that utilizes an outer steel pipe for structural strength and an inner polymer liner pipe for corrosion resistance.
By implementing CORE Linepipe®’s ClickWeld® system with an electro-fusion coupling, the polymer liner can be pre-installed in a controlled factory environment eliminating a large amount of field work. CORE Liner® is a superior alternative to traditional field installed liners as it provides simplified construction and enhanced reliability at a lower cost.
ClickWeld® based products are pre-manufactured in a controlled production environment providing an improved level of product quality and reliability. Field activities such as welding, radiography, and secondary hydrostatic testing are eliminated providing customers with significant savings, improved safety, and minimized environmental impact.
With a decade of operational excellence and a track record of zero operational releases, CORE Linepipe Inc. provides unparalleled reliability, ensuring uninterrupted performance and peace of mind for your pipeline projects.
CORE Liner is a pipe-in-pipe system engineered to deliver unmatched corrosion resistance, safeguarding your infrastructure against the harshest environments and extending its lifespan significantly.
CORE Linepipe® project involvement starts with the manufacturing process, where we produce a robust corrosion resistant pipeline system that includes:
• ClickWeld® Mechanical Joints
• A factory installed internal high-density polyethylene (HDPE) liner
• Integral Electrofusion joining system
CORE Liner® introduces a corrosion-resistant pipe-in-pipe system, merging the high-pressure capacity of steel with the unparalleled corrosion resistance of plastics. The outer steel pipe, accompanied by a pre-installed inner HDPE liner, offers true dual containment, providing comprehensive protection against both internal and external corrosion, from flange to flange.
ClickWeld® is the innovative proprietary mechanical joining system of CORE Linepipe®. The ClickWeld® system uses high grade carbon steel components to form a connection that is gas and liquid-tight, eliminating the need for field welding.
We’ve taken an innovative approach to pipeline manufacturing while streamlining the installation process and delivering significant savings in capital and operating expenses. No environmental releases over hundreds of projects throughout North America since 2014 and a competitive total installed cost has allowed CORE to grow with our clients through challenging market conditions and demonstrate our approach works.
CORE Linepipe has proven to be an excellent product to work with. The installation process is efficient and streamlined with experienced oversight by CORE Linepipe representatives. It has been rewarding to work with CORE Linepipe and their team.

Over the last 6 years, Purnell has had the pleasure of working with CORE Linepipe and has been successful in installing sizable lengths in the Grande Prairie area for various clients.
