Type: Alloy 1.4958 LWN Flange
Material: Incoloy Alloy 800H (UNS N08810)
Size: 1-1/2″ (DN40) Length: 713mm
Class / Pressure: 300#
Wall Thickness: SCH-STD
Standard: ASME B16.5
Long weld neck flange (LWN flange) is also call integral flange, it means a welding neck flange has a very long neck. Commonly, the welding neck flange has a tapered neck and a bevel end which is going to butt welding with the matching pipe. But the long weld neck flange, has a straight short pipe as the neck of a long weld neck flange. Long weld neck flange (LWN flange), is used for high pressure situations, integral hub weld neck flanges are used and for very high pressure cases Long Welding Neck flanges are preferred. In this case, the weld are far from the ring to avoid bending stresses and weld stress being combined.

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.
