Welding Neck Flanges
Welding Neck Flanges are distinguished from other types by their long tapered hub and gentle transition of thickness in the region of the butt weld joining them to the pipe. The long tapered hub provides an important reinforcement of the flange proper from the standpoint of strength and resistance to dishing.

Threaded Flanges
Threaded Flanges are confined to special applications. Their chief merit lies in the fact that they can be assembled without welding this explains their use in extremely high pressure services, particularly at or near atmospheric temperature, where alloy steel is essential for strength and where the necessary post weld heat treatment is impractical. Threaded flanges are unsuited for conditions involving temperature or bending stresses of any magnitude, particularly under cyclic conditions, where leakage through the threads may occur in relatively few cycles of heating or stress; sea welding is sometimes employed to overcome this, but cannot be considered as entirely satisfactory.

Spectacle Blind Flanges
Spectacle Blind Flanges Separating one part of a line from another requires a spectacle blind, able to switch from closed to open and back again. Bleed rings provide a means to release pressure from the pipe through a controlled opening.

Socket Weld Flanges
We offer socket weld flanges were initially developed for use on small size high pressure piping. When provided with an internal weld, their static strength is equal to, but their fatigue strength 50% greater than double welding slip-on flanges. Smooth bore conditions can readily be attained (by grinding the internal weld) without having to bevel the flange face and, after welding, to reface the flange as would be required with slip-on flanges. The internally welded socket type flange is popular in chemical process piping for this reason.

Slip On Flanges
We offer slip on flanges continue to be preferred to welding neck flanges by many users on account of their initially lower cost, the reduced accuracy required in cutting the pipe to length, and the somewhat greater ease of alignment of the assembly; however their final installed cost is probably not much, if any, less than that of welding neck flanges.

Orifice Flanges
We offer orifice flanges are widely used in conjunction with orifice meters for measuring the rate of flow of liquids and gases. They are basically the same as standard welding neck and slip-on flanges except for the provision of radial, tapped holes in the flange ring for meter connections and additional bolts to act as jack screws to facilitate separating the flanges for inspection or replacement of the orifice plate. In choosing the type of orifice flange, the considerations affecting the choice of welding neck and slip-on standard flanges apply with equal force.

Long Welneck Flanges
The lwn is fvc's basic standard flanged connection. This seamless product offers a nominal bore as well as a heavy wall thickness making it ideal for highly corrosive applications.

Lap Joint Flanges
We offer lap joint flanges are primarily employed with lap joint stubs, the combined initial cost of the two items being approximately one-third higher than that of comparable welding neck flanges. Their pressure-holding ability is little, if any, better than that of slip-on flanges and the fatigue life of the assembly is only one-tenth that of welding neck flanges.
