The UNS N08825 DIN W.NR. 2.4858 Seamless Pipe is a nickel - iron - chromium alloy pipe that offers excellent resistance to a wide range of corrosive media, especially in wet and harsh environments. The alloy composition includes significant amounts of nickel, chromium, molybdenum, and copper, which work together to provide superior corrosion resistance and mechanical properties.
This seamless pipe is produced using state - of - the - art manufacturing processes to ensure high precision and quality. The seamless construction ensures a smooth internal surface, which minimizes fluid friction and allows for efficient flow of liquids and gases. It complies with international standards, making it a reliable choice for global industrial applications.
One of the most notable features of the UNS N08825 DIN W.NR. 2.4858 Seamless Pipe is its outstanding resistance to chloride - induced stress corrosion cracking. It performs exceptionally well in saline environments, such as seawater and brine solutions, where many other materials fail due to stress corrosion. The pipe also has excellent resistance to general corrosion in a variety of acids, including sulfuric acid, hydrochloric acid, and phosphoric acid, especially at moderate temperatures.
In addition to its corrosion resistance, the pipe has good mechanical properties at both ambient and elevated temperatures. It can withstand moderate high temperatures and has sufficient strength for pressure - bearing applications. The alloy is also known for its good weldability and formability, which makes it easy to fabricate into complex shapes and integrate into existing piping systems.
The UNS N08825 DIN W.NR. 2.4858 Seamless Pipe is widely used in industries that deal with corrosive fluids and harsh environments. In the marine industry, it is used for seawater intake systems, offshore pipelines, and shipboard equipment, where the constant exposure to seawater requires materials with high corrosion resistance.
In the chemical processing industry, it is suitable for transporting and processing various acids, as well as for equipment in pickling plants and fertilizer production. The pipe is also used in the oil and gas industry, particularly in offshore oil fields where the presence of saltwater and corrosive gases poses a challenge to material selection. Additionally, it can be found in the water treatment industry for pipelines and equipment handling brackish water and wastewater, where resistance to chloride and other contaminants is essential.
