The LPG Copper Strip Corrosion Test Apparatus is a complete, precision-engineered system designed to evaluate the corrosiveness of liquefied petroleum gas (LPG) to copper under elevated temperature conditions, conforming fully to ASTM D1838 and related specifications. The apparatus provides accurate, repeatable, and standardized corrosion assessment for LPG samples using a polished copper strip immersion test.
Copper strip corrosion testing is a critical procedure for assessing the presence of corrosive sulfur compounds and reactive contaminants in liquefied petroleum gas. These impurities can cause metal degradation, leakage, and failure in pipelines, cylinders, and valves during transport or storage.
The Koehler LPG Copper Strip Corrosion Test Apparatus enables laboratories to perform the ASTM D1838 test with precision and efficiency. The system immerses a pre-polished copper strip in an LPG sample contained within a test cylinder maintained at elevated temperature in a controlled water bath. After a fixed duration (typically one hour), the strip is compared visually with the ASTM Copper Strip Corrosion Standards to classify the corrosion tendency of the LPG sample.
This comprehensive setup includes corrosion test cylinders, temperature-controlled water bath, ASTM-standard copper strips, polishing materials, and corrosion color standards, providing everything needed for reliable, repeatable, and compliant testing.
