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 the CORE 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.
We chose CORE Linepipe’s new technology not just because of the significant time and cost savings but also because of the long-term integrity benefits. In this environment when pipelines are coming under increased public and regulatory scrutiny, we wanted a system that we wouldn’t have to even think about for generations. The new CORE Liner™ and ClickWeld™ technologies provided that solution at a discount to what we would have had to pay for older technologies. Given the benefits, we would not hesitate to use this technology on any pipelines we construct in the future.
