The significance of predicting the corrosion of copper sheets by petroleum products in advance for industrial production?

Anticipating the corrosion of copper sheets by petroleum products in advance has multiple important implications for industrial production, mainly reflected in the following aspects:

ensuring equipment safety and service life.

Copper corrosion tests can detect corrosive components such as free sulfur and active sulfides in petroleum products, which can directly corrode metal equipment (such as internal combustion engine fuel supply systems, storage tank pipelines, etc.), leading to equipment damage or leakage accidents. For example, sulfides in liquefied gas will react with copper sheets to form black precipitate Cu ₂ S, and a concentration exceeding 0.5ppm may lead to corrosion failure.

Optimizing production processes and quality control

In petroleum refining processes, copper corrosion tests can qualitatively evaluate the effectiveness of desulfurization processes. For example, if the copper flakes of crude gasoline refined from high sulfur crude oil quickly turn black, active sulfides need to be removed through alkaline washing or acid-base refining. This test is the core testing method of GB/T 5096 standard, which directly affects whether the product meets industry standards.

Reduce maintenance costs and operational risks.

Fuel frequently comes into contact with metal components such as copper alloys and aluminum alloys during transportation, storage, and use. Anticipating corrosion risks in advance can avoid economic losses caused by equipment replacement or maintenance downtime. For example, if the corrosion level of aviation fuel exceeds the standard, it may cause fuel supply system failures.

The copper corrosion test is not only used for petroleum products, but also applicable to fields such as automotive manufacturing and electronic components to ensure safety in expanding application areas. For example, if lubricating oil additives corrode copper sheets, it may cause short circuits in the internal circuits of precision instruments.

Promoting environmental protection and compliance. Leakage of corrosive substances may pollute the environment. By detecting and controlling corrosive components, sulfur-containing waste gas emissions can be reduced, in compliance with environmental regulations.

SD5096 petroleum products copper corrosion tester is according to the standard of the People's Republic of China GB/T5096 equivalent ASTMD130 copper corrosion test method of the petroleum products the requirements stipulated in the design and manufacture, apply to specified by the standard test method, evaluation of aviation gasoline, aviation turbine fuel, motor gasoline, farm tractors, washing solvent, kerosene distillate fuel and lubricating oil and other petroleum products for copper corrosion degree.
