ASME SB163 N08825 Nickel Alloy Seamless Tube For Condensers And Heat Exchangers
YUHONG GROUP deal with stainless steel seamless pipe and tube already more than 33 years, every year sell more than 80000 tons of stainless steel seamless pipe and tube. Our client already cover more than 65 countries. Our stainless steel seamless pipe and tube was width used in Mining, Energy, Petrochemical, Chemical Industry, Food plant, Paper plant, Gas and Fluid Industry etc.
ASME SB163 N08825 is a specification that covers seamless nickel alloy tubes made from grade N08825 material. N08825 is a nickel-iron-chromium alloy with additions of molybdenum, copper, and titanium. It is commonly known as Incoloy 825.
This specification is applicable for tubes in sizes ranging from 1/8" to 5" in outside diameter and 0.015" to 0.500" in wall thickness. The tubes are intended for general corrosion resistance and high-temperature applications.
The ASME SB163 N08825 nickel alloy seamless tubes are typically used in industries such as chemical processing, oil and gas, power generation, and marine applications. They offer excellent resistance to various corrosive environments, including sulfuric acid, phosphoric acid, and seawater.
The tubes are manufactured using various processes, including cold working, hot working, and annealing. They are tested for mechanical properties, such as tensile strength and yield strength, as well as other quality requirements like flattening, flaring, and hydrostatic testing.
ASME SB163 N08825 nickel alloy seamless tubes provide excellent corrosion resistance, high strength, and good weldability, making them suitable for a wide range of demanding applications.
