S32750 Super Duplex Steel Weld Neck Flanges

Zhejiang Chengyuan S32750 Super Duplex Steel Weld Neck Flanges Introduction

Flat welded flanges with neck have a lower neck height which enhances their stiffness and load-bearing capacity. These flanges require a larger amount of welding work and higher electrode consumption compared to butt-welding flanges. They may not be suitable for withstanding high temperature and pressure or repeated bending and temperature fluctuations. However, they are popular due to their convenience in on-site installation, which eliminates the need for welding seam patting kneading process.

On the other hand, butt-welded flanges, also known as "high junction" flanges, are designed to transfer pressure to the pipe, reducing stress concentration in the flange base. They are best suited for butt welds due to their structural value. However, their production process is relatively complicated, resulting in a higher price compared to other flange types.
