Where are aluminum pads used?

Where are aluminum pads used? Can it be used on high-pressure equipment? Medium: ethylene, high pressure, category 3 container. Can I use another type of metal gasket? Or a toothed pad? This post was last edited by GUANGWEI8.26 on 2009-4-17 15:05.]
Metal gaskets feature high strength and good heat resistance; the appropriate material should be selected based on the corrosivity of the medium. Common materials for metal gaskets include iron, steel, alloy steel, copper, aluminum, nickel, silver, etc. Among them, aluminum pads are widely used, with a service temperature of up to 400°C. Aluminum gaskets with a purity of 99.8% can be used for sealing 98% concentrated nitric acid. Gaskets can be made in forms such as flat gaskets, toothed gaskets, elliptical gaskets, octagonal gaskets, and lens gaskets. The main disadvantages of aluminum gaskets are high pre-tension, complex processing, and high cost; therefore, they are generally used in high-pressure vessels.
Aluminum gaskets can be used in high-pressure equipment; I have seen drawings showing such use in the past
It can be used as a gasket on high-pressure equipment. For example, the pressure in the ammonia synthesis section is 31.4 Mpa.
Aluminum gaskets are mainly used in high-pressure containers, but they are relatively expensive. Metal wound gaskets can also be used.
So, which one has greater pre-tightening force, the aluminum gasket or the metal wound gasket? And what is the difference in performance between the rust-resistant aluminum gasket and the regular aluminum gasket?
