The HDPE liner we installed last month has held up perfectly against the sulfuric acid line. No measurable permeability after 30 days of continuous flow at 80°C. The dimensional stability during thermal cycling was better than the previous PTFE lining we used.

Communication during the setup phase was clear and the team addressed our concerns about joint sealing. The multi-axial stress test results they shared gave us confidence. Only minor delay on the custom extrusion profile, but the final fit was precise.

Returning client after three years — the new pipeline system with the upgraded liner formulation shows even better thermal degradation resistance. We ran accelerated aging tests at 150°C for 500 hours and saw zero cracking. Consistent quality across batches.
