CIPL Structural Integrity Testing
Starline CIPL installed in a cast iron natural gas pipeline reinforces the structural integrity and safety of the existing pipe. This video shows the physical differences when crushing a lined and ...
Starline® CIPL has undergone more than $15 million in independent testing across multiple facilities. These results confirm that the bonded liner maintains its structural and pressure integrity over a century-long design horizon. Full testing data and reports are available upon request.

CIPL has been independently verified through PHMSA and ASTM testing to maintain pressure integrity far above regulatory thresholds. While cast-iron and low-pressure systems are commonly tested at 1.5 × MAOP (≈ 37.5 psig for 25 psig systems), Starline® CIPL has demonstrated safe operation at pressures exceeding 450 psig. Each installation follows the utility's approved testing protocol in ...
CIPP Liner Testing : How Certified Labs Ensure Quality & Longevity for Cured-in-Place Pipe Certified laboratory testing of CIPP liners validates structural integrity , confirms specification compliance, and guarantees 50+ year service life for trenchless pipe rehabilitation projects.

Overview of Cipl Structural Integrity Testing
Collaborative RD&D for Natural Gas Utilities Description: A testing program to provide experimental data on the expected durability and longevity of the CIPL system when used in cast iron (CI) and steel pipes. Status: The testing for CIPL longevity and durability for up to 100 years is complete. Residual follow-on testing of liner tensile and adhesion properties is expected to be completed in ...
1.2.1 Continued growth of external corrosion, if undetected and unmitigated, could result in loss of the host pipe structural integrity to such an extent that the liner becomes the sole pressure bearing element in the rehabilitated pipeline structure.
Key Details About Cipl Structural Integrity Testing
The results of finite-element simulations were compared with the experimental fault rupture response of jointed pipelines with and without CIPL reinforcement. The results of a numerical model that accounts for debonding between the lining and pipe as Mode II fracture propagation were in good agreement with full-scale fault rupture test results.
