UNS N08020 Slip On Flange Mechanical Properties

ASTM B462 UNS N08020 weld neck flange is a nickel iron chromium austenitic alloy expands with the addition of copper and molybdenum for maximum resistance to acid attack particularly sulfuric acids. It provides excellent general resistance to corrosion in chemical such as chloride, nitric, sulfuric and phosphoric acids.

Which means that it offers strong chloride corrosion cracking resistance. It also consist niobium for stabilization against sensitization and resultant corrosion. It outdo in corrosion resisting to hot sulfuric acids.

Incoloy 20 blind flange is use to connect pump, pipes, valves and other tool to make pipework structure. Usually it is threaded or welded and two flange can be connected by bolting it with gasket and by providing a seal that offer an easy access to the piping systems. This flange are available in many types.

Below are carpenter 20 pipe flanges types

  1. Slip-On Flange is a ring which is place over pipe end. The flange face extend from pipe end by sufficient distance to apply welded bead to the inner diameter. As the name recommend, the flange slip over pipe and it is known as slip-on flange.
  2. Weld neck flange is also known as high neck flange or tapered hub flange. It has a neck which can properly transfer the pipe tension. It also aid to reduce the pressure gathered at the flange bottom. It is suitable with pipelines which operate at high or low temperature and resists high pressure.
  3. Socket weld flange are connected outside just by a fillet weld. It is usually not recommended for a demanding situation. It is useful for the small bore line in a system. Its fatigue strength is 50% higher than double-welded slip on flange and the static strength is equivalent to slip on flange.
  4. Blind Flange production happens without a bore and it is used to blank off the end of pressure vessel opening, valves and pipes. If it is considered from the point of view of bolt loading and internal pressure, it is the most overstressed type of flange and it is quite big.
  5. Lap joint flange is use with stub ends when the pipe is made from expensive material.

2.4660 alloy 20 swrf flange are extending rims, edges ribs or collars which is used to make a connection between two pipes or between a pipe and any fitting type or equipment component. It is use for dismantling system of pipe for temporarily installation.
