Long Neck Welding (abbreviated LWN) flanges are almost like a typical Welding Neck flange, but the “Neck” is considerably longer. This kind is usually used as a nozzle for a barrel or column. Additionally, there are the kind LWN Heavy Barrel (HB) and therefore, the Equal LWN Barrel (E); they need a special shape and a thicker “Wall.”
Long Weld Neck Flanges include an extended tapered hub that aid in reinforcement and supply temperature / pressure resistance. Bored to match the within diameter of the mating pipe or fitting, these flanges are directly welded to the end of the pipe. Long weld neck flanges are ideal for high pressure applications and a key advantage of using them is that they are doing not interfere with the flow of fluid through the flange. If you place the weld joint at the neck of the flange, the pipe is far easier to align and you can achieve a stronger weld.

ANSI B16.5 Long Weld Neck Flange Weight Calculation
The weight of a long welding neck flange can be calculated by using the following equation :
Mass = [ ( X + B ) / 2 * ( X – B ) / 2 * 0.0246615 * ( Y – T ) * 10-3 ] + [ ( D2 – B2 – nd2 ) * T + ( G2 – B2 ) * t ] * 6.165375 * 10-6, Assume that the flange is made of carbon steel.

Features of Long Weld Neck Flanges
- Long Weld Neck Flanges are carefully bored to match the within diameter of the adjoining pipe so there’s no restriction in flow. This helps to stop turbulence at the joint and reduces erosion considerably.
- Long Weld Neck Flanges feature an extended tapered hub that goes gradually over to the wall thickness from a pipe. this provides strong reinforcement for high pressure, high temperature and sub-zero applications.
- The tapered hub is made by a gradual increase in thickness of the metal from the weld joint to the flange face. This makes it ideal for conditions of repeated bending caused by line contraction, expansion,or other external forces.
Benefits of Long Weld Neck Flanges
- Easy to align between the flange and pipe.
- Easy access for radiography testing to examine the integrity of welding.
- The internal stress is transferred to the pipe through the Long Weld Neck making the connection more durable and stronger.
- The flange face is kept far from heat affected area
- Perfect for high pressure systems and may affect high and low temperatures.
- No interference with flow of the reduces turbulence and liquid.
