Introduction to Inconel 600 Fittings

pipe fittings

 Inconel 600 is a nickel-chromium alloy with high-temperature oxidation resistance, as well as resistance to carburization and chloride corrosion. It is extremely versatile and can be used in a variety of applications ranging from cryogenics to applications with elevated temperatures up to 2000°F.

The many advantageous properties of Inconel 600 are

  • At high temperatures, good oxidation resistance
  • Most alkaline solutions and sulfur compounds are compatible
  • Resistance to both organic and inorganic compounds when it comes to corrosion
  • Resistance to chloride ion stress corrosion cracking                                   
  • Hence, Inconel 600 Fittings is the perfect alloy to used to manufacture fittings. 

Some of the various types of Inconel 600 fittings and their applications are explained below.

  1. ELBOW: They help to change the directions of piping. It allows us to reroute threaded pipes or to turn corners and they also require less space.

  1. 45° – This elbow fitting help to change the direction of the fluids inside the pipe at a 45 degree angle.
  2. 90° – This elbow fitting help to change the direction of the fluids inside the pipe at a 90 degree angle.

  1. TEE: This type of fitting is T-shaped which has two outlets at 90° at the connection to the main line.

  1. Branch – A tee fitting with female connections on two ends and male connection on the third.
  2. Run 

  1. UNION: It is usually a short fitting used to connect two pipes and is easily removable as it is not a permanent fixture. 

  1. Cross – This pipe fitting is manufactured like a cross and is used to connect four pipes together. It could have one inlet and three outlets, or the other way around.
  2. Tube Socket Weld – It has a screwed joint design and three connected pieces i.e. two internal threads and a centerpiece that draws the ends when rotated. 

  1. FERRULE: It is a kind of fitting made of various materials which are used for joining or binding one part to the other.

  1. Back – It is smaller and interacts with the nut.
  2. Front – It bites down between the tube and the fitting body creating a seal.

  1. REDUCER: It is used to reduce the inner diameter of the pipe.

  1. Concentric – They have a cone like shape and have a common center line.
  2. Eccentric – They have one straight side and one of the edges running parallel to the connecting pipe, this results in the centerline being offset.

  1. STUB END: They are mechanical joints consisting of two components and are used to secure joints between two lengths of pipe.
  2. ADAPTER: It is used to connect dissimilar pipes. On one end, adapters may have male or female IPS threads, with the opposite gender on the other, which must be welded or soldered onto a smaller pipe.
  3. CAP: It is used to close the ends of the pipes and tubes.
  4. PLUG: It serves the same function as a cap. It also stops a pipe or tube system as they are plugged like a stopper at the end.
  5. PIPE BEND: Bends are used in fluid transportation that requires pigging. They have a radius of curvature of more than twice the pipe’s diameter and can be made as per requirement.
