Reducing tee 54x35x54 mm - thin-walled galvanized carbon steel, swaged PC5130 0543554

Application in Sanitary and Industrial Installations

This component, belonging to the group of steel fittings for press-fit systems, is used to connect pipes of different diameters in water supply, heating, and fire protection installations. Thanks to its reducing tee design, it enables a smooth transition from a 54 mm pipe to pipes with a smaller cross-section (in this case, 35 mm), which is crucial when designing extensive distribution networks. The material – alloy carbon steel – ensures the mechanical strength required for systems operating under pressure, while the galvanic zinc coating protects against corrosion in humid environments.

Construction and Installation Method

The key feature of this tee is the press-fit connection system, which eliminates the need for welding or threading. Installation is quick and safe using dedicated hydraulic or manual tools, reducing on-site work time. Each of the three connections (two with a diameter of 54 mm and one reducing connection of 35 mm) features a stop collar that precisely positions the pipe before pressing, ensuring uniform compression of the seal.

It is worth noting the surface specifics: although the external part is galvanized, the areas in contact with the pipe (surface treatment) remain in a raw state. This is an intentional technological solution for press-fit systems – it allows for direct metal-to-metal contact during pressing, guaranteeing mechanical tightness of the joint without risking damage to the protective coating in the critical zone.

Operational Parameters and Resistance

This component is designed for operation under conditions requiring resistance to high pressures. The maximum working pressure is 16 bar at a temperature of 20°C, making it suitable for most standard internal installations and some industrial circuits. The steel construction ensures system rigidity, and the absence of seals inside the body itself (the seal is located only in the pressing head) minimizes the risk of failure due to aging of elastic materials within the medium flow.

In practice, this means a connection with dimensions 54 × 35 × 54 mm, made of alloy steel and protected with a galvanic coating. Such a configuration allows installation in systems requiring a change in pipe diameter while maintaining structural rigidity and pressure resistance up to 16 bar. Due to the lack of need for additional sealing elements or welds, this connection is characterized by repeatable tightness and durability throughout the entire service life of the installation. It is a solution dedicated to installers who value fast installation and to investors requiring reliable media distribution systems.
