Understanding the different types is key to building an efficient and safe system. Below, we’ll explore some of the most common designs and their face types.

Pipe Flanges, Base Flanges, and Specialty Designs

In industrial applications, pipe flanges are the most common type used to connect pipes and other components. They are essential in industries like chemical processing, oil and gas, and water treatment, where secure connections are critical. These flanges ensure that pipes, valves, and pumps can be connected and disconnected for maintenance without cutting the pipe.

Base flanges, on the other hand, are designed for structural applications. You’ll often find them used to secure railings, fences, and posts to floors or walls, providing a stable and durable foundation. Specialty designs, such as large-diameter or custom-drilled flanges, are created for specific projects like marine engineering or HVAC exhaust systems.

Some of the most frequently used pipe flanges include:

• Flensa Leher Las: Feature a tapered hub that provides reinforcement, making them ideal for high-pressure and high-temperature services.
• Blind Flanges: Solid discs used to block off a pipeline or vessel opening, allowing for easy access for inspection or maintenance.
• Lap Joint Flanges: Used with a stub end, they allow for rotational alignment of bolt holes, simplifying assembly in complex piping systems.
• Socket Weld Flanges: Designed for smaller-diameter, high-pressure pipes, these create a strong, leak-tight joint.

Common Face Types: Raised Face, Flat Face, and Ring Joint

The face of a flange is the surface that makes contact with a gasket to create a seal. The type of face you choose is critical for ensuring a tight seal and preventing leaks in your piping system. The three most common face types each serve a different purpose and are compatible with different kinds of gaskets.

A secure installation depends on matching the flange face type with the correct gasket and bolting procedure. For instance, a raised face flange concentrates pressure on a smaller gasket area, creating a stronger seal. In contrast, a flat face flange requires a full-face gasket to prevent the flange from cracking under bolt tension.

Here are the primary face types and their characteristics:

• Wajah Terangkat (RF): The gasket surface is raised above the bolting circle, making it the most common type for industrial applications.
• Wajah Datar (FF): The entire face is flat, typically used in low-pressure and low-temperature applications.
• Ring Type Joint (RTJ): Features a groove where a metal ring gasket sits, designed for high-pressure and high-temperature services to create a metal-to-metal seal.
