The CNC Pipe Thread Rolling Machine forms external threads on pipes, tubes and other hollow metal workpieces through three-axis rolling. Three dies apply forming pressure around the workpiece, providing radial support during thread formation.
The reference configuration supports workpieces up to Ø60 mm, rolling pressure up to 250 kN and thread pitches up to 6 mm. Actual capacity depends on pipe diameter, wall thickness, material, thread dimensions and tooling.

Workpiece and Thread Requirements
Before quotation, provide:
Pipe outside diameter
Inside diameter and wall thickness
Material grade
Hardness or tensile strength, if available
Thread standard and profile
Thread diameter
Pitch
Thread length
Required tolerance
Expected production quantity
A drawing or sample is recommended for thin-wall pipes, special materials and non-standard threads.
Thread Standards and Tooling
The required thread standard should be confirmed before die production.
For NPT applications, ASME B1.20.1 specifies dimensions and gaging requirements for general-purpose inch pipe threads. ISO 7-1 covers pressure-tight pipe threads using mating threads for sealing.
The machine should not be described as certified to a thread standard unless specific certification or test documentation applies. Dies and process parameters should be selected according to the required thread profile.
Applications
Steel Pipe Threading
External threads can be formed on suitable carbon steel and alloy steel pipes for threaded connections. Material condition and wall thickness should be checked before production.
Scaffolding Components
Threaded steel tubes and related tubular components can be processed when their dimensions and material are within the forming range.
Industrial Pipe Components
Suitable for external thread forming on tubular components used in mechanical equipment, piping assemblies and other industrial applications.
Batch Production
CNC parameter control supports repeat production of the same pipe and thread specification, making the machine suitable for manufacturers, distributors and contract production.
Manufacturing, Testing and Buyer Information
The machine goes through component machining, mechanical assembly, hydraulic and electrical installation, CNC commissioning and final running tests before shipment.
For wholesale quotations, buyers should provide:
Pipe diameter and wall thickness
Material grade
Thread standard, profile and pitch
Thread length
Rolling die requirements
Motor and electrical requirements
Production quantity
Automation requirements, if applicable
Spare parts and packaging requirements
When specifications alone cannot confirm suitability, a pipe drawing or sample can be provided for technical evaluation. This is especially useful for thin-wall pipes, special materials and non-standard thread profiles.
