ASTM D130 refers to a standard test method issued by the American Society for Testing and Materials (ASTM) for determining the corrosiveness of petroleum products. In this context, the "Petroleum Products Copper Strip" refers to a specific type of copper strip used in this corrosion test.
Here's a description of the ASTM D130 petroleum products copper strip:
Material: The copper strip used in ASTM D130 is typically made from high-purity copper. The purity of the copper strip is important to ensure accurate and consistent test results.
Dimensions: The copper strip used in ASTM D130 has specific dimensions defined by the standard. It is typically rectangular in shape and has a length of 100 mm (3.9 inches), a width of 25 mm (0.98 inches), and a thickness of 0.4 mm (0.016 inches). These dimensions are standardized to ensure consistency across testing laboratories.
Surface Condition: The copper strip used in the ASTM D130 test should have a clean, smooth, and uniform surface. Any contaminants or surface imperfections can affect the test results.
Corrosion Test: The purpose of the ASTM D130 test is to evaluate the corrosiveness of petroleum products, such as gasoline, diesel fuel, lubricating oils, and other similar substances. The copper strip is immersed in the petroleum product for a specified period under controlled temperature conditions. After the test, the copper strip is visually inspected for signs of corrosion or tarnishing.
Corrosion Rating: The corrosion of the copper strip is classified based on a rating system defined in the ASTM D130 standard. The rating scale ranges from 1A (no corrosion) to 4B (severe corrosion), with intermediate ratings indicating varying degrees of corrosion.
Corrosion Protection: The ASTM D130 test provides valuable information about the corrosiveness of petroleum products. It helps assess the potential impact of these products on equipment, pipelines, storage tanks, and other infrastructure that may come into contact with them. The test results aid in determining appropriate corrosion prevention measures, such as the use of corrosion inhibitors or suitable materials for construction.
It's important to note that the ASTM D130 test is just one of several methods used to assess the corrosiveness of petroleum products. Other tests, such as ASTM D665 and ASTM D7548, are also commonly employed in the evaluation of corrosion properties.
Pure copper is a rose red metal, the surface of the formation of copper oxide film is purple, so industrial pure copper is often called copper or electrolytic copper. Fire smelting can obtain 99-99.9% pure copper, electrolysis can make the purity of copper to 99.95-99.99%. It has a density of 8-9g/cm3 and a melting point of 1083°C. Pure copper conductivity is very good, a large number of used in the manufacture of wire, cable, brush and so on; Good thermal conductivity, commonly used to manufacture magnetic instruments, instruments, such as compasses, aviation instruments, etc. Excellent plasticity, easy to hot press and cold pressure processing, can be made into tubes, rods, wires, strips, belts, plates, foils and other copper materials. Pure copper products have two kinds of smelting products and processed products. Product specifications are complete, the price is favorable, the packaging is intact, the copper is pure, the straightness is good, the inventory is large, can provide material certification and SGS report.
character:Good electrical conductivity. Corrosion resistance and processability, can be welded and fiber welding. Contains less impurities that reduce electrical conductivity, and a trace amount of oxygen is conductive to electricity. Thermal conductivity and processing properties have little impact, but it is easy to cause "hydrogen disease", and it is not suitable for processing (annealing) in a reducing atmosphere at high temperatures (such as >370°). Welding, etc.) and use
