Core Steel Pipe Production Line Capabilities
High-Frequency ERW Pipe Mills: Configured for continuous, high-efficiency welding of steel tubes and pipes.
Process Flow: Uncoiling and Strip Joining - Form Roll Design - High-Frequency Induction Welding - Bead Scarfing and Cooling - Sizing and Straightening - Flying Cut-Off - Automatic Stacking and Handling.
Spiral Submerged Arc Welded (SSAW) Pipe Lines: Designed for large-diameter, heavy-duty welded pipe manufacturing.
Process Flow: Coil Preparation and Leveling - Spiral Forming Station - Internal Submerged Arc Welding (SAW) - External SAW - NDT Testing - Plasma Cutting - End Facing and Beveling.
Cold-Formed & Roll Forming Lines: Custom-built for continuous production of structural steel profiles (C, Z, U profiles, and solar mounting sections).
Downstream Pipe Processing: Precision auxiliary modules including cutting, hydro-testing, end-facing, straightening, and NDT inspection to upgrade existing lines.

|
Steel Grade (API, Carbon, Alloy) |
Influences high-frequency oscillator sizing, squeeze roll pressure, and heat treatment |
|
Target Production Capacity |
Defines line speed (meters/min), drive configuration, and handling tempo |
|
Pipe Length & Tolerances |
Influences flying saw synchronization accuracy and stacking mechanism layout |
|
Testing & Quality Standards |
Determines inline NDT, hydrostatic test pressure ratings, and inspection modules |
|
Workshop Layout Constraints |

|
Electrical Power Supply |
Custom-matched to local grid voltages (e.g., 380V/415V/480V, 50Hz/60Hz) |
Mechanical, Electrical & Hydraulic Integration
Heavy-duty cast-steel stands, precision ground shafts, and high-load bearings ensure rigidity and vibration dampening.
Integrated automation using standard PLC systems (Siemens/Schneider) and touch-screen HMIs to centralize uncoiling, welding power, line speed, and cut-off tracking.
High-response power units provide stable clamping, lifting, roll adjustment, and shearing forces with reliable pressure control.
Technical Review:
Comprehensive evaluation of raw material specifications, output goals, and factory floor blueprints.
Custom Configuration:
Tailored layout design, electrical schematics, and mechanical assembly drawings matching your process.
Manufacturing & Assembly:
CNC machining of mill stands and strict assembly under veteran engineers.
Inspection Before Shipment:
Client or third-party inspection (SGS, BV, TUV) supported prior to export packaging.
Installation & Commissioning:
On-site mechanical erection, electrical wiring, PLC commissioning, and operator training.
Manufacturing & Quality Inspection Protocol
Component Inspection:
Strict incoming checks on raw steel, forgings, bearings, and electrical parts against agreed specifications.
Assembly Audits:
Precision laser alignment checks for mechanical parallelism, wiring verification, and pressure testing of hydraulic circuits.
Pre-Shipment Factory Acceptance Testing (FAT):
Fully assembled core sections undergo dry-run functional testing, control system simulation, and safety verification prior to export crating.
