1. Alloy 20 Chemistry & Specifications

Also known as Carpenter 20 and 20CB-3, Alloy 20 flanges offer users a combination of nickel, chromium, molybdenum, and copper which provides good general corrosion resistance. Alloy 20 flanges are best suited for mid-range corrosion use – better than steel alloys but not at the level of high performance nickel based alloys like Hastelloy C276. Alloy 20 is a nickel alloy that was specifically designed to withstand the harsh environment of hot sulfuric acid but also performs well in a variety of other acids. Alloy 20 flanges are an ideal choice when you don’t need the corrosion resistance power and price-tag of high performance nickel alloys like Hastelloy C276; but you need something that will give you more protection than 316 stainless steel or even a Super Duplex 2507 stainless steel.

3. What is the difference between Alloy 20 seamless and welded pipe?

  • Seamless pipe is manufactured by extruding the metal to the desired length; therefore ERW pipe have a welded joint in its cross-section, while seamless pipe does not have any joint in its cross-section through-out its length.
  • An advantage of ERW pipe is that no fusion metals are used and the weld seam cannot be seen or felt. That’s opposed to double submerged arc welding (DSAW), which leaves behind an obvious weld bead that must then be eliminated depending on the application.
  • Manufacturing seamless pipe
  • Seamless piping begins as a solid cylindrical hunk of steel called a billet. While still hot, billets are pierced through the center with a mandrel. The next step is rolling and stretching the hollow billet. The billet is precisely rolled and stretched until it meets the length, diameter and wall thickness as specified by the customer order.

4. Alloy 20 nickel alloy pipe common test:

IRIS test

The internal rotary inspection system (IRIS) is an ultrasonic non-destructive testing (NDT) technique used to inspect pipes and tubes.

Benefits

IRIS testing has several advantages over others:

  • Works on all materials, regardless of properties.
  • Full sensitivity near tube support structures such as tubesheets.
  • Perfect as a backup to electromagnetic testing.
  • Very accurate wall thickness measurement results.
