Lap-Joint Flanges
Lap-joint flanges are a type of flange used in piping systems to connect pipes, valves, and other equipment. They are designed to slide over the end of the pipe and are typically used in conjunction with a stub end or lap joint stub. Lap-joint flanges are commonly used in low-pressure and non-critical applications, such as in water treatment plants, cooling systems, and certain industrial processes. They are available in a variety of materials, sizes, and pressure ratings to suit different requirements
Key Features of Lap-Joint Flanges
Here are some key features of Lap-Joint Flanges
- Slide-On Design : Lap-joint flanges slide over the pipe end, facilitating easy alignment during installation.
- Bolted Connection : They are bolted to a stub end or lap joint stub, providing a secure connection without welding the flange to the pipe.
- Rotational Flexibility : The flange is free to rotate around the stub end, allowing for easy alignment of bolt holes.
- Easy Disassembly : Since the flange is not welded to the pipe, it can be easily removed for maintenance or modifications without cutting or modifying the pipe.
- Versatility : Lap-joint flanges are suitable for low-pressure applications and come in various materials, sizes, and pressure ratings to accommodate different requirements.
- Cost-Effective : They can be more cost-effective than fully welded flanges, especially in applications that require frequent maintenance or modifications.
- Corrosion Resistance : Depending on the material used, lap-joint flanges can offer excellent corrosion resistance, making them suitable for a wide range of environments.
- Compliance : Quality lap-joint flanges are manufactured to meet industry standards such as ASTM, ASME, DIN, JIS and API ensuring reliability and performance in various applications
