Nickel Long Weld Neck Flanges have a hub that extends from the flange's flat surface, which helps in accommodating the pipe more easily. Alloy Steel Long Weld Neck Flange fall under the group of speciality flanges, providing reinforcement in services at higher temperatures in the oil industry. A Carbon Steel Long Welding Neck Flanges is preferable in the petroleum and chemical industry as they operate under fluctuating temperature ranges.
Long Weld Neck Flanges come in different sizes, but the most common sizes range from 1/2 inch to 24 inches in diameter. The length of the weld neck varies depending on the diameter of the flange. For example, a 6-inch flange might have a 4-inch long weld neck, while a 24-inch flange might have a 10-inch long weld neck.
Long Weld Neck Flanges are a type of pipe flange with a long, tapered neck that is butt-welded to the pipe. They are used in high-pressure applications, such as oil and gas pipelines, where their long neck provides additional reinforcement & reduces stress concentrations at the base of the flange. They are also used in applications where the pipeline needs to be insulated, as the long neck provides space for the insulation material.
The primary reason to use a Long Weld Neck Flange is its ability to reduce stress concentrations and provide additional support to the pipeline. The long neck allows for a smooth transition from the pipe to the flange, which helps to distribute stresses more evenly and reduces the risk of fatigue failure. Additionally, the long neck provides ample space for welding and insulation, which can further enhance the integrity & performance of the pipeline.
