Weld Neck FLANGE
Weld Neck Flanges are designed for high-pressure and high-temperature applications. These flanges are distinguished by their long tapered hub, which provides excellent reinforcement at the joint and reduces stress concentration. They are welded to the pipe, ensuring a strong and leak-proof connection. Weld Neck Flanges are ideal for critical services in industries such as oil & gas, petrochemical, power generation, and shipbuilding. Their robust design and precise dimensions make them suitable for demanding applications where reliability and safety are essential.
