Dec 20, 2023 View: 78

1. Flange gaskets: These are used to create a tight seal between flange connections. They come in different materials such as rubber, cork, PTFE (polytetrafluoroethylene), and metal, depending on the specific requirements of the flange connection.

2. Flange bolts and nuts: These are used to secure flanges together. They come in various sizes and materials, including carbon steel, stainless steel, and alloy steel. It's important to use the correct bolt and nut combination to ensure proper flange connection integrity.

3. Flange studs: These are similar to bolts but without a head. They are threaded on both ends and used in conjunction with nuts to secure flanges. Studs offer advantages in certain applications, such as easier installation and removal compared to bolts.

4. Flange insulation kits: These kits are used to electrically isolate flange connections to prevent galvanic corrosion. They typically include insulating gaskets, insulating sleeves, and washers made of materials like phenolic, PTFE, or neoprene.

5. Flange protectors: These are used to safeguard flange faces during transportation, storage, or maintenance. They can be made of plastic, rubber, or metal and are designed to prevent damage to the flange surface, such as scratches or corrosion.

6. Flange alignment tools: These tools help ensure proper alignment of flanges during installation. They include alignment pins, jackscrews, and alignment bars. Proper alignment is crucial for achieving a secure and leak-free flange connection.

7. Flange lubricants: These are used to reduce friction and ease the installation of flanges. Lubricants can be applied to the flange faces or bolts/nuts to facilitate tightening and prevent galling or seizing.
