Rothenberger Comb Series, SS, BSPT R, 2.1/2 - 4" - 56294

Features of the Rothenberger Chaser Dies SS BSPT R 2.1/2 - 4 Series (56294)

The Rothenberger Chaser Dies SS BSPT R 2.1/2 - 4 Series (item code 56294) represents a professional solution for threading large diameter pipes. Made from high-quality special steel (SS), these chaser dies are specifically designed to create conical BSPT R (British Standard Pipe Taper) threads on pipes with diameters ranging from 2.1/2 to 4 inches. The precision manufacturing ensures threads comply with international standards, guaranteeing perfect seals in hydraulic and gas installations.

These chaser dies are compatible with professional series Rothenberger threading machines, allowing for precise and clean threading even on particularly resistant materials. The tooth geometry has been optimized to reduce effort during cutting, leading to increased equipment lifespan and less operator fatigue during prolonged use.

Main Applications

Rothenberger chaser dies from the SS BSPT R series are particularly suitable for:

• Large-scale industrial hydraulic installations
• Piping systems for fire suppression systems
• Industrial gas distribution networks
• Centralized heating systems
• Large-scale irrigation systems
• Fluid pipelines in petrochemical plants
• Marine and offshore installations

Technical Advantages

Using Rothenberger SS BSPT R series chaser dies offers numerous benefits to professional installers:

• High wear resistance thanks to hardened special steel
• Threading precision compliant with international standards
• Reduced cutting effort due to optimized tooth geometry
• Longer lifespan compared to standard chaser dies
• Compatibility with leading professional Rothenberger threading machines
• Clean threads requiring minimal finishing operations
• Also suitable for particularly resistant materials

Maintenance and Care

To ensure maximum durability and optimal performance of Rothenberger chaser dies, it is recommended to follow some simple maintenance practices. Regularly clean the chaser dies after use, removing metal residue and chips with a wire brush. Apply a light layer of protective oil before storing them to prevent oxidation. During use, ensure that an adequate cutting oil is used to reduce friction and dissipate heat generated during threading.

Proper maintenance not only extends the useful life of the chaser dies but also ensures consistent thread quality over time. In case of excessive wear or damage, it is recommended to replace the entire set to maintain the precision of the threads produced.

Tips for Optimal Use

To achieve the best results with Rothenberger SS BSPT R series chaser dies, it is important to use the appropriate rotation speed based on the material to be threaded. Harder materials require lower speeds. Ensure that the pipe is correctly clamped and centered in the threading machine. Use plenty of cutting oil during the operation to ensure clean and precise threading, as well as to extend the life of the chaser dies themselves.
