MS Union Fitting 15x20 mm

Mild Steel Union for Industrial Pipe Systems

A pipe union is a critical fitting that enables two pipes to be joined and disconnected without cutting or de-threading. This 15x20 mm MS (Mild Steel) union is specifically suited for medium-pressure applications where a robust, threaded connection is required. Its design consists of three parts: a nut, a female end, and a male end, which together form a reliable seal when tightened.

In abrasive blasting and surface preparation environments, pipework is subjected to constant vibration, media flow, and wear. A well-machined MS union provides a balance of strength and machinability, making it a common choice for compressed air lines, abrasive feed pipes, and dust collection ducting. The 15x20 mm size indicates a reducing union, connecting a 15 mm pipe to a 20 mm pipe, which is essential for adapting different pipe diameters in a system.

Key Features and Benefits

• Reducing Design: Connects 15 mm and 20 mm nominal bore pipes, simplifying system design and reducing the need for additional adapters.
• Mild Steel Construction: Offers good tensile strength and ductility, suitable for threading and withstanding mechanical stress in industrial settings.
• Ease of Maintenance: The union joint allows for quick disassembly of pipe sections for cleaning, inspection, or replacement of downstream equipment like valves, nozzles, and filters.
• Leak-Resistant Seal: Metal-to-metal seating surfaces, when properly installed with a suitable thread sealant, provide a dependable seal against air or fluid leakage.

Applications in Surface Preparation

This MS union fitting is typically integrated into the support infrastructure of blasting and spray equipment, rather than the direct high-wear path. Common application points include:

• Compressed Air Manifolds: Joining air supply lines to blast pots or spray guns.
• Abrasive Feed Piping: Connecting sections of rigid pipe that transport abrasive media from a hopper to a blast nozzle (in low to medium-pressure systems).
• Dust Collector Ducting: Linking ductwork sections in ventilation and dust extraction systems.
• Cooling Water Lines: For equipment like thermal spray guns that require water cooling.

Selection and Compatibility Guidance

To ensure a correct fit and safe operation, please verify the following before ordering:

• Thread Standard: Confirm if your system uses BSP (British Standard Pipe), NPT (National Pipe Taper), or another thread standard. Mismatched threads will cause leaks and damage.
• Pressure Rating: Check the maximum operating pressure of your system against the fitting's rating. This is especially critical in compressed air applications.
• Media Compatibility: While mild steel is robust, confirm its chemical compatibility with any fluids or slurries in your process to avoid premature corrosion.
• Installation: Always use appropriate thread sealant (PTFE tape or liquid sealant) and tighten to recommended torque specifications. Avoid over-tightening, which can crack the nut or distort the seating surfaces.
