Rothenberger Die Set, SS, NPT, 1/2 - 3/4" - 56111

Features of the Rothenberger SS, NPT Die Set, 1/2 - 3/4 - 56111

The Rothenberger SS, NPT Die Set, 1/2 - 3/4 - 56111 represents a professional solution for threading stainless steel pipes. These dies are specifically designed to create precise NPT (National Pipe Thread) threads that comply with industrial standards on pipes with diameters ranging from 1/2 to 3/4 inches. Made from high-quality steel, they guarantee long durability even under intensive use and with particularly resistant materials like stainless steel.

The dies from the 56111 series are compatible with Rothenberger threading machines, ensuring a perfect fit that optimizes cutting precision and reduces effort during operation. The tooth geometry has been designed to ensure clean and precise threads, minimizing the formation of burrs and imperfections that could compromise the seal of fittings.

Professional Applications

These dies are used in numerous professional sectors where NPT standard threading of stainless steel pipes is required:

• Industrial and civil plumbing systems requiring watertight connections
• Air conditioning and refrigeration systems
• Oil and gas plants where corrosion resistance is necessary
• Marine and offshore sector with exposure to saline environments
• Food and pharmaceutical industry where compliance with hygienic standards is required
• Water treatment and corrosive fluid systems

Technical Advantages

The Rothenberger 56111 series offers several advantages over standard dies:

• Greater abrasion resistance due to specific heat treatment
• Superior precision in creating NPT threads compliant with American standards
• Reduced cutting effort due to optimized tooth geometry
• Less wear during stainless steel processing
• Easy replacement and compatibility with Rothenberger die heads
• Longer operational life compared to standard dies

Technical Specifications

The dies in the 56111 series are characterized by technical specifications that guarantee their reliability and precision:

• Thread type: NPT (National Pipe Thread)
• Supported diameters: 1/2 to 3/4 inch
• Die material: special tool steel with heat treatment
• Compatibility: Rothenberger die heads
• Application: specific for stainless steel (SS)
• Compliance with ANSI/ASME B1.20.1 standards for NPT threads

Maintenance and Use

To achieve optimal results and extend the lifespan of Rothenberger 56111 dies, it is advisable to follow some simple maintenance practices. Always use a cutting lubricant specific for stainless steel during threading operations to reduce friction and overheating. Thoroughly clean the dies after each use, removing any metallic residues that could compromise cutting precision in subsequent applications. Store the dies in a dry and protected environment to prevent oxidation and damage.

Correct pressure during threading is essential: excessive pressure can prematurely damage the dies, while insufficient pressure can generate imprecise threads. Always follow the manufacturer's instructions regarding rotation speed and feed rate during threading operations.
