ZUANGONG Drilling & Tapping | G-NRT Pipe Extrusion Tap

Today, we are proud to introduce a revolutionary product that integrates cutting-edge materials, advanced coating technology and exquisite craftsmanship – the ZUANGONG G-NRT Extrusion Tap for Pipe and Extrusion Machines.

In pipeline connection, valve body manufacturing and the assembly of various mechanical equipment, high-quality internal threads are the core to ensuring sealing performance, safety and durability. However, traditional cutting taps often face challenges such as chip removal difficulties, easy wear and low thread precision during processing. To address these industry pain points, ZUANGONG, driven by innovation, has launched this extrusion tap specially designed for high-standard pipe thread processing.

If top-tier base material is the "inner strength" of a tap, then advanced coating technology is its indestructible "armor". ZUANGONG equips its Extrusion Taps for Pipe Extrusion Machines with three high-performance coatings to accurately tackle a variety of complex machining environments and material characteristics.

We offer you the following three coating options:

These three coatings are like equipping a valiant warrior with battle armors of distinct functions. Whether you’re facing hard "boulders" or sticky and tough "marshes" in machining, there is always one option to help you work with ease and conquer every challenge.

Core Advantages: Why Choose ZUANGONG Extrusion Taps for Pipe Extrusion Machines?

• Chip-free machining for greater environmental friendliness and efficiency: As an extrusion tap, it forms threads through metal plastic deformation with no chips generated, completely solving the chip removal problem of cutting taps. It is particularly suitable for blind hole machining and keeps the working environment cleaner.
• Higher thread strength: Threads formed by extrusion feature continuous, unbroken metal fibers. Thus, their tensile strength, shear strength and fatigue resistance are all superior to those of cut threads.

• Exceptional surface finish: Extrusion machining work-hardens the thread surface for an ultra-high finish, resulting in low friction torque and superior sealing performance.
• Extra-long service life: The powerful combination of high-quality HSSE base material and high-performance coatings endows the tap with incredible durability, effectively reducing the frequency of tool replacement and overall production costs.

ZUANGONG Extrusion Taps for Pipe Extrusion Machines are more than just a tool; they are our commitment to precision and efficiency. Integrating premium material technology from Japan with our years of craftsmanship expertise, they are designed to deliver the most reliable thread machining solutions for every customer striving for excellence.
