ASTM D6137 Polymer Lining Sulfuric Acid Resistance FAQs
The ASTM D6137 test method is intended to evaluate the sulfuric acid resistance at elevated temperatures of polymer linings applied to carbon steel substrates subject to a sulfuric acid attack.
ASTM D6137 provides direct evidence of how polymer linings behave when exposed to sulfuric acid. This helps engineers select materials that resist degradation, ensuring long-term protection of equipment operating in highly corrosive industrial environments.
The test can reveal failures such as swelling, cracking, blistering, softening, or surface degradation. These issues indicate poor chemical resistance and can lead to leakage, contamination, or structural failure in real applications.
The test cannot evaluate the area inside the scrubbed gas streams at temperatures below the water dew point. The physical or mechanical effects and chemicals present in the flue gas can affect actual lining performance.
Higher acid concentrations typically increase the severity of chemical attack, leading to faster degradation. Testing at relevant concentrations ensures realistic evaluation of material performance under actual service conditions.
According to ASTM D6137, polymer linings applied to carbon steel panels are exposed to sulfuric acid at elevated temperatures. The specimens are evaluated for cracking, blistering, and other signs of deterioration to determine acid resistance.
According to ASTM D6137, polymer-coated steel panels are subjected to sulfuric acid exposure and controlled temperature cycles. The coatings are inspected for blistering, cracking, adhesion failure, and other damage to assess their chemical resistance.
