Description

Technical Field

[0001] This utility model relates to the field of copper strip corrosion testing technology, and in particular to a copper strip corrosion testing device for petroleum products. Background Technology

[0002] The copper strip corrosion tester is designed and manufactured in accordance with the People's Republic of China petrochemical industry standard SH / T0232 "Test Method for Corrosion of Copper Strips by Liquefied Petroleum Gas", and can be used to determine the corrosion of copper strips by liquefied petroleum gas.

[0003] In existing technologies, the copper sheet corrosion test involves pouring the oil sample to be tested into a clean, dry test tube, immersing a polished, washed, and dried copper sheet in the oil sample, plugging the test tube with a cork with an air vent, or placing the test tube inside a test bomb, and then placing the test tube or test bomb into a water bath or oil bath at a certain temperature. After the test, the copper sheet is removed, washed, and compared with a corrosion standard color chart to determine the corrosion level.

[0004] The existing Chinese patent application number 200910253695.3, entitled "A Rapid Tester for Copper Strip Corrosion," clearly describes that during the test, the oil sample to be tested and the polished copper strip are placed in a U-shaped tube, heated to react, and then the copper is removed. The U-shaped tube is sealed to the top cover with a cork. This method is inconvenient for taking out and putting in the U-shaped tube, and the cork can only fix one U-shaped tube. However, testing with only one U-shaped tube results in the uniformity of the test results. Utility Model Content
