GI Cross Fitting 25x15 mm

Understanding the GI Cross Fitting 25x15 mm

In abrasive blasting and surface preparation systems, pipe networks must handle continuous flow of compressed air and abrasive particles. A cross fitting creates a four-way junction, allowing operators to branch lines to multiple blast stations, regulators, or media recovery points from a single supply header. The 25x15 mm size indicates the nominal bore dimensions, making it suitable for specific pipe diameters within a blasting setup.

Galvanized iron (GI) is chosen for its protective zinc coating, which resists atmospheric corrosion in industrial environments. While not as wear-resistant as specialized alloys in direct abrasive flow paths, GI fittings offer a cost-effective and durable solution for air distribution lines and secondary abrasive handling circuits where extreme abrasion is not the primary concern.

Key Features and Benefits

• Four-way connection: Enables efficient branching of air or media lines to multiple points of use, reducing the need for multiple tees and elbows.
• Galvanized iron construction: Provides a protective zinc layer that guards against rust in humid or mildly corrosive industrial atmospheres.
• Standardized dimensions: The 25x15 mm size is designed to mate with compatible GI pipe sizes, simplifying system layout and spare parts inventory.
• Industrial compatibility: Suited for integration into existing abrasive blasting, shot blasting, and spray equipment pipework where GI fittings are specified.

Applications in Surface Preparation

This cross fitting is typically found in the pipe networks of:

• Abrasive blasting systems: Distributing compressed air and media from a central pot to multiple blast hoses or nozzles.
• Shot blasting machines: Routing air to various pneumatic controls, blow-off stations, or dust collector purge lines.
• Industrial spray equipment: Branching air supply lines for thermal spray guns or paint spray systems.
• General workshop air lines: Creating junction points in fixed compressed air piping for surface preparation bays.

Selection and Compatibility Considerations

Before ordering, confirm the exact pipe outer diameter and thread type (if applicable) in your system. The 25x15 mm designation refers to nominal size; actual dimensions may vary slightly between manufacturers. Verify that the fitting's pressure rating meets your system's maximum operating pressure. For applications where the fitting is in the direct path of high-velocity abrasive flow, consider the expected service life and inspect regularly for wall thinning.
