Weld neck Flanges are drilled (machined) with the wall thickness of the flange having the same dimensions of the matching pipe. The lighter the pipe is, the larger the bore, conversely, the heavier the pipe, the small the bore. They are normally used for high-pressure, cold or hot temperature. Flanges 1/2" to 24" and up to 450 lbs to BS10 Table D & Table E, BS Table F & Table H, BS Table J & Table K. We can also manufacture in different shapes and sizes depending upon your purpose. 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. flanges are unsuited for conditions involving temperature or bending stresses of any magnitude, particularly under cyclic conditions. |
