What is a welding neck RTJ flange?

Welding Neck RTJ Flange is designed to withstand high pressure and temperature. It is commonly used in offshore drilling rigs and subsea pipelines, as well as nuclear power plants, petrochemical plants, oil refineries and power plants.

The WN RTJ flange has a neck that can be welded to the pipe, and has a bore that matches the inside diameter of the pipe. It is commonly used in high pressure applications such as power plants, nuclear power plants, petrochemical plants and oil refineries. It also used in offshore drilling rigs and subsea pipelines.

Welding neck ring type joint flange is used in high pressure applications.

It is the most popular gas flange and the most widely used types of flanges in the world. The welding neck ring joint is designed for leak-free applications at high pressure. Welding neck RTJ Flange (WNR) can be made with a wide range of materials, including carbon steel, stainless steel, nickel alloy and titanium alloys. In fact, it is one of the most versatile types of flanges on the market today because it can be produced in many different materials with a variety of features depending on your application needs.

Fabrication and Heat Treatment

Machinability

Super alloy VLX800H can be machined using the common processes applied to iron based alloys. This alloy does work-harden during machining and displays higher strength and “gumminess” unlike steels. It is recommended that heavy duty machining equipment and tooling should be used to reduce chatter or work-hardening of the alloy.
Any commercial coolants can be used during the machining operations; however water-based coolants are recommended for high-speed operations such as milling, turning, or grinding. Similarly, heavy lubricants are ideal for tapping, broaching, drilling, or boring.

Forming

Super alloy VLX800H can be formed using any of the conventional methods as it is very ductile. Powerful equipment is required to perform forming operations as this alloy is strong. It is recommended that heavy-duty lubricants be used while performing cold forming. It is important to clean all traces of lubricant after forming.

Welding

Welding of super alloy VLX800H can be performed using all the traditional welding methods. Matching alloy filler metal should be used. In case that is not available, it is advised that the nearest alloy closest to the chemical composition be used. The weld beads should be slightly convex, and preheating is not required. Surfaces to be welded have to be clean and free from oil, paint or crayon marking.

Forging

Forging should be performed in the temperature range of 1204-982°C (2200-1800°F).

Hot Working

Hot working can be performed in the temperature range of 1204-871°C (2200-1600°F).

Cold Working

Super alloy VLX800H can be cold formed using all the standard tools except for plain carbon tool steels as they produce galling.

Annealing

Super alloy VLX800H can be annealed at 1176°C (2150°F) and then air cooled.

Applications

  • Super alloy VLX800H is used in the following application areas:
  • Piping for petrochemical plants
  • Heaters and heat exchangers that are used in prolonged high temperature environments.
