The ALCO RX-173 GR-1003 flange set is a premium quality accessory designed for use in various applications, particularly in the plumbing and heating industries. This set includes two flanges, each measuring 7/8 inches outside diameter (OD), making it suitable for pipes and vessels with similar dimensions.
The flanges in this set are made of GR-1003 material, which is a type of gray iron casting. This material is known for its excellent strength, durability, and resistance to wear and tear. The flanges are also designed with raised faces, which provide a flat, even surface for making a seal when joining pipes or vessels.
The ALCO RX-173 GR-1003 flange set comes with National Pipe Thread (NPT) threads on both sides, allowing for easy and secure attachment of pipes or fittings. The threads conform to the ASME B1.20.1 standard, ensuring compatibility with a wide range of pipe and fitting components.
Each flange in the set features a groove for a gasket, which is used to create a tight, leak-free seal between the flanges and the pipes or vessels they are joining. The groove is designed to accommodate standard ASME B16.5 gaskets, providing flexibility in selecting the appropriate gasket material for the specific application.
The ALCO RX-173 GR-1003 flange set is finished with a protective coating, which helps to prevent rust and corrosion. This coating ensures that the flanges maintain their structural integrity and functionality, even in harsh environments.
In summary, the ALCO RX-173 GR-1003 flange set is a high-performance, versatile accessory designed for use in various industrial applications. Its 7/8 inch OD, GR-1003 material, NPT threads, gasket groove, and protective coating make it an excellent choice for joining pipes and vessels with confidence and reliability.
