DIN/JIS/GB/ANSI 150LB/300LB Flange：WNRF,PLRF,SOFF,SWFF

ANSI 150LB and 300LB flanges are essential components for securing and connecting pipes in various industrial applications. The Welding Neck Flange (WNRF) offers enhanced strength and stability with a long neck for smooth bore alignment. The Plate Flange (PLRF) is a flat, circular design ideal for easy installation in low to medium-pressure systems. The Slip-On Flange (SOFF) slips over the pipe and is secured by welding, providing a reliable connection. Lastly, the Socket Weld Flange (SWFF) features a socket that fits snugly over the pipe, ensuring a secure and leak-free connection. Each type is available in Class 150 and 300, suitable for different pressure requirements and made from materials like carbon steel or stainless steel.
