11/2″-1″-11/2″ HAK-PI Stainless Steel Threaded Reducing Coupling
Corrosion-resistant stainless steel coupling for fast, leak-free pipe diameter reduction.
The HAK-PI Threaded Reducing Coupling is a stainless steel fitting that safely joins pipes of different diameters. In addition, its 1 1/2 inch to 1 inch to 1 1/2 inch configuration adapts a main pipeline to a smaller auxiliary line. Moreover, threaded connections at both ends speed up installation and eliminate the need for extra gaskets.
The stainless steel body withstands high pressure and temperature fluctuations, therefore performing reliably in chemical and humid environments. Furthermore, the smooth internal surface reduces flow loss and prevents turbulence. As a result, the coupling operates safely in both water and steam lines.
HAK-PI Threaded Reducing Coupling — Technical Specifications
Chemical and petrochemical plants use this coupling to connect pipes of different diameters. In addition, food and beverage production lines rely on it for hygienic pipe transitions, while fire suppression systems and compressed air distribution networks use it for dependable connections. Consequently, it shortens labor time by eliminating welding in standard pipe transitions.
Key Advantages
- Stainless steel construction offers superior resistance to corrosion and chemicals.
- Threaded connection type allows fast installation and easy maintenance with a detachable structure.
- Withstands high pressure and temperature, ensuring safe operation under demanding industrial conditions.
Applications
- Joining pipe lines of different diameters in chemical and petrochemical plants.
- Hygienic pipe transitions in food and beverage production lines.
- Reliable connections in fire suppression systems and compressed air distribution lines.
Ultimately, the HAK-PI Threaded Reducing Coupling is an ideal solution for changing pipe diameters in industrial facilities. ORFA supplies worldwide and provides technical support, so contact our expert team for the right sizes for your project.
