Alloy 20 flanges

Alloy 20 Flanges

Alloy 20 can be described as an austenitic stainless steel that has less than 50% iron in its chemical composition. The nickel alloy 8020 pipe flange are developed to be used in applications that takes place in the sulphuric acid environment. The Alloy 20 flanges also has nickel and chromium in its alloy, which adds to its corrosion resistance properties in a wide range of chemical environments and aggressive media. The 20cb3 Alloy 20 hot forged flange is stabilized with niobium so as to reduce intergranular corrosion. The Alloy 20 Blind Flanges are cost-saving when compared to other flanges made with nickel alloy, and it outperforms different stainless steel grades. The nickel alloy 20 weld flanges is fit to be used till a maximum temperature of 1000 degrees F, and it can be formed either by hot-working or cold-working using traditional methods. Due to these properties, the 20cb3 Alloy 20 Slip-on Flanges are widely used in industries like petrochemical, pharmaceutical, marine, chemical processing, and so on.

MCT test can be conducted on Carpenter 20 Flange. The test report should match the required specification.

The maximum pressure rating for Alloy 20 Pipe Flanges is 2500.

To find out the right Carpenter 20 Slip On Flange dimensions, the outer diameter of the pipe or flange where it is to be connected and the inner diameter of the given flange should be checked. They should match to fit perfectly.

The MTC and hydro test report of Alloy 2.4660 Flanges contain the following:

  • At the top, you will get information about the manufacturer who manufactured the material.
  • The heat number or lot number is specified in the test. All the material properties including chemical properties, mechanical properties, etc., are linked with the heat number. These properties are known as the technical delivery conditions.
  • The test report also contains the material specification and grade. While reading the reports, these should be matched with the minimum requirements given in material specification for technical and delivery conditions.
  • The MTC should also comply with the delivery conditions, like manufacturing process, type of flange, etc.
  • It also has a material dimension.
  • The mechanical properties will be present in the MTC for each heat number.
