Lap Joint Flanges

Lap Joint Flanges are specially designed to be used with a stub end fitting. Unlike weld neck or slip-on flanges, the flange itself does not come into contact with the fluid inside the pipeline. Instead, it is slipped over the pipe and positioned behind the stub end.

Key Highlights:

• Allows easy alignment and adjustment of bolt holes.
• Suitable for applications where frequent dismantling is required.
• Cost-effective since the flange can be reused while only the stub end requires welding.
• Commonly used in low-pressure and non-critical applications.

Ring Type Joint (RTJ) Flanges

Ring Type Joint Flanges (RTJ) are designed for high-pressure and high-temperature applications. They feature a precision-machined groove in which a metal ring gasket is placed. When the flange bolts are tightened, the gasket is compressed into the groove, ensuring a strong and leak-proof seal.

Key Highlights:

• Provides superior sealing performance under extreme conditions.
• Suitable for offshore, refinery, and chemical industries.
• Designed to prevent leakage in hazardous and critical piping systems.
• Available in different classes such as Class 600, 900, 1500, and 2500.

Advantages of Joint Flanges

• Joint Flanges are inexpensive
• They are quite suited for corrosive applications.
• Joint Flange require only a single full penetration butt weld.
• Only the stub end has contact with the process medium
• These Flanges can be easily adjusted to align with the mating flange.
• It is available in almost all pipe diameters.
• Ideal for systems where frequent disassembly of the flange is required e.g. when cleaning or inspection is required.
• It is possible to use a cheaper grade material for the Joint Flange e.g. carbon steel because only the stub end must match the associated pipe material/grade; this can result in considerable cost savings.
