Why is it necessary to measure copper sheet corrosion in petroleum products? Since crude oil contains acids, the vast majority of products derived from it have a certain degree of acidity (corrosivity), and the corrosion of copper sheets is used to measure the corrosivity of petroleum products ； Different indicators are applicable to terminals of different levels. For example, liquefied gas is corrosive; it causes slight corrosion to steel equipment and has a melting effect on rubber. All terminals used for filling liquefied gas incorporate plastic pipes, and due to its high corrosivity, this certainly poses a danger. The copper sheet corrosion tester complies with GB/T 5096, GB/T 7326, ASTM D4048, SH/T 0232, ISO 6251, SH/T 0023, and ASTM D130; it is suitable for determining the degree of corrosion of copper sheets caused by aviation gasoline, jet fuel, automotive gasoline, natural gasoline, or other hydrocarbons with a vapor pressure at 100°C not exceeding 124 kPa (930 mm Hg), as well as solvent oils, diesel fuel, distillate fuels, lubricating oils, greases, and other petroleum products. Instrument features: The intelligent measurement and control system has a self-diagnosis function. A metal bath with precise temperature control for testing baths. The copper sheet corrosion test time can be set and alarmed. PID temperature control technology is adopted.
