Stainless Steel Pipe Cross is a type of pipe fitting designed to connect four pipes at 90-degree angles, forming a cross shape. Made from stainless steel, this fitting offers excellent corrosion resistance, making it suitable for a wide range of applications, especially those involving chemicals, food processing, pharmaceuticals, and marine environments.
A stainless steel cross, also known as a four-way pipe fitting, is designed to connect four pipes at 90-degree angles, forming a cross shape. Made from stainless steel, it offers excellent corrosion resistance and durability, making it suitable for various applications.
This fitting is crucial in systems requiring high purity and hygiene, such as food processing, pharmaceuticals, and marine environments. It allows for the distribution or collection of fluids from different directions, enhancing the efficiency and flexibility of the system.
Stainless steel crosses are valued for their strength, versatility, and ability to withstand harsh conditions, ensuring reliable performance and long service life.
Based on Connection Method | |
Type | Description |
Butt Weld Stainless Steel Cross | Welded directly to pipes for a strong, leak-proof connection. Ideal for high-pressure and high-temperature systems. |
Socket Weld Stainless Steel Cross | Pipes are inserted into sockets and fillet-welded. Suitable for smaller pipe sizes and high-pressure applications. |
Threaded Stainless Steel Cross | Features threaded openings (NPT or BSP) for easy assembly and disassembly. Used in low to medium-pressure systems. |
Based on Size Configuration | |
