About this product
Product information from the supplier.
The Z28-300 Thread Rolling Machine is a high-precision industrial solution engineered specifically for steel bars and tubing. Utilizing advanced cold-forming technology, this automatic machine produces threads with exceptionally low internal stress, effectively eliminating the risk of stress corrosion—a critical advantage when working with stainless steel. By replacing traditional cutting methods, it ensures that the structural integrity of the tube wall remains intact, providing superior strength and reliability for high-pressure applications.
Designed for versatility and efficiency, the Z28-300 is an ideal choice for demanding environments such as fire control high-pressure water mist extinguishing systems, where pipeline work pressures can reach up to 16MPa. With its robust PLC control system and precision-engineered rollers, the machine delivers consistent, high-quality threading that is as rigid as the tube body itself, ensuring leak-proof connections and long-term durability in industrial piping systems.

Frequently Asked Questions
Q: What is the main advantage of thread rolling over thread cutting for steel bars?
Thread rolling displaces material rather than removing it, which creates a stronger thread with lower internal stress and higher fatigue resistance compared to cutting.
Q: Can this machine handle stainless steel tubing?
Yes, the Z28-300 is specifically designed to solve stress corrosion issues in stainless steel, making it ideal for high-pressure stainless pipelines.
Q: What is the typical delivery time for the Z28-300 model?
The standard delivery time is approximately 30 days after order confirmation.
Q: Do you provide installation services outside of China?
Yes, we have a professional engineering team available to provide overseas installation, adjustment, and training services.
Q: Which certifications does the machinery hold?
Our machines are manufactured under strict quality standards and hold CE and ISO9001 certifications.
Q: Can the voltage be adjusted for different regions?
Absolutely. While the standard is 380V/3Phase/50Hz, we can customize the voltage and frequency to meet your local requirements.
