中文简体Nickel is one of the noble metals in the galvanic electrochemical series and combines with other elements like copper, iron, and molybdenum to form alloys with superior resistance to corrosion. Adding chrome, titanium, and other elements to the alloy increases its resistance even further. As a result, nickel is a perfect material for making tubing and pipes that can be used in harsh environments. Nickel tubes are often used in naval condensers, evaporators and heat exchangers.
The most common type of nickel-alloy tube is made from a combination of copper and nickel, with other elements like iron or manganese added to make it stronger. This combination allows it to be easily welded, while still being strong enough for use in corrosive environments. PJ tube offers several different grades of nickel-alloy tubes to meet the needs of customers. Some are available in a wide range of diameters and wall thicknesses, while others are made with specific characteristics in mind for certain types of applications.
Alloys that are more resistant to corrosion and oxidation are often used in the manufacturing of industrial equipment, especially when they need to be exposed to corrosive chemicals. Nickel-based alloys are the best choice for these applications because they have excellent resistance to a wide variety of acids, such as sulfuric acid, hydrochloric acid, and phosphoric acid. They also have good resistance to oxidation in alkaline solutions.
Other alloys that are used for similar purposes are copper-nickel, austenitic nickel-iron-chromium-molybdenum and nickel-chrome. These alloys are often used for load bearing components that are subjected to high temperatures and corrosive chemicals, such as chlorine, sulfuric acid, and phosphoric acid.
Compared to other types of alloys, nickel is particularly suited for building seawater heat exchangers because it has very good resistance to saltwater corrosion. However, it is important to note that titanium is sometimes chosen as an alternative material for these kinds of tubes because it has a higher rate of heat transfer and can guarantee a very durable end product.
Another variant of nickel alloy that can be used to manufacture tubes and pipes is monel. This is a cost-effective option that can be hardened through hot and cold working to give it a robust structure. It is also a very good choice for marine applications because of its superior resistance to seawater corrosion, as well as for heat exchangers and rocketry. Moreover, it has very good thermal, magnetic, and electrical properties.
