Flange adaptor is a fitting used in piping systems to connect different types of pipes or equipment, typically allowing for the transition between pipes with different flange standards or diameters. It consists of a flange on one end and a pipe or fitting on the other, facilitating secure connections while maintaining the integrity of the system.

1.Versatility: Flange adaptors can accommodate various pipe materials (such as PVC, ductile iron, or steel) and sizes, making them adaptable to different piping systems.
2.Secure Connections: The flange design allows for a tight, leak-proof connection, usually achieved by bolting the flanges together, ensuring durability and reliability in the system.
3.Ease of Installation: Flange adaptors simplify the process of connecting dissimilar pipes or equipment, reducing the need for additional fittings or complicated modifications.
4.Alignment and Stability: They help in aligning pipes and providing stability, especially in systems subjected to movement or vibration.
Flange adaptors are commonly used in water supply and wastewater systems, HVAC applications, and industrial piping. They are essential for connecting valves, pumps, and other equipment to pipelines, enabling the efficient flow of fluids while accommodating various pipe materials and sizes.
