Applications

1. Connection of Pipes

Pipe nipples serve as connectors between two pipes, allowing for a seamless transition and extension of pipes in a system. This is especially useful in plumbing and industrial applications.

2. Fluid Transport

They are commonly used in systems that transport liquids and gases, including water supply, oil, and chemical lines, ensuring secure and leak-free connections.

3. Hydraulic Systems

Pipe nipples are critical in hydraulic systems, linking hoses and equipment to maintain fluid pressure and flow, essential for machinery operation.

4. Chemical Processing

In chemical plants, pipe nipples are used to connect various pieces of equipment and transport corrosive substances safely, often made from special materials like stainless steel for added durability.

5. Industrial Equipment

They are widely used in various industrial equipment applications, including compressors, pumps, and machinery, allowing for versatile assembly configurations.

6. Marine Applications

In marine environments, pipe nipples are often employed in plumbing and fuel systems, where corrosion resistance and reliability are critical.
