ASTM B729 NO8020 Seamless Pipe
YUHONG GROUP deal with stainless steel seamless pipe and tube already more than 33 years, every year sell more than 12000 tons of stainless steel seamless pipe and tube. Our client already cover more than 65 countries.
Description
ASTM B729 is the standard specification for seamless pipe made of nickel-iron-chromium alloy known as Alloy 20, which is also designated as NO8020. This alloy is highly resistant to corrosion, particularly in sulfuric acid environments, making it suitable for use in various industries such as chemical processing, pharmaceutical, and food processing.
The seamless pipe manufactured in accordance with ASTM B729 specifications ensures high quality and reliability for applications requiring corrosion resistance and high temperature strength. It is often used in piping systems for handling corrosive fluids and chemicals.
ASTM B729 NO8020 seamless pipe is a durable and versatile solution for industries requiring a reliable and corrosion-resistant piping system.
