Alloy 20 is a highly versatile material that finds use in a wide range of industries. It is resistant to corrosion and acid attacks and offers excellent mechanical properties. As a result, it has become a popular choice for flanges – connecting pieces that join two pipes or valves.
Various types of Alloy 20 flanges include weld neck, blind, slip-on, socket weld, and threaded flanges. Weld neck flanges are the most commonly used, and they have long neck that accommodates high stresses. Blind flanges are ideal for sealing off a pipeline or equipment. Slip-on flanges are easy to use and are perfect for low-pressure applications. Socket weld flanges are ideal for smaller pipes because they are cost-effective and allow easy flow control. Threaded flanges are versatile and can be used for low- and high-pressure applications.

Alloy 20 flanges can be used in a variety of environments. They are commonly used in harsh environments that require resistance to sulfuric acid, phosphoric acid, and chloride stress corrosion cracking. They are also used as a substitute for nickel-based alloys in applications where the cost is considered. Furthermore, the flanges can join different materials with varying corrosion levels.
One of the main benefits of Alloy 20 flanges is their superior corrosion resistance, which is much better than stainless steel or Hastelloy. They are also resistant to pitting and crevice corrosion, which makes them ideal for aggressive environments. Additionally, alloy 20 flanges have a long lifespan and require minimal maintenance, which makes them a cost-effective choice in the long run. Their excellent mechanical properties make them ideal for high-strength and durability applications.
Alloy 20 flanges are a versatile and popular choice for various applications. They offer excellent mechanical properties and superior corrosion resistance, which makes them a reliable and durable choice for joining pipes or valves. The different types of Alloy 20 flanges provide a range of options which can be used in various environments, including harsh and aggressive ones.
