Product Overview


About the Manufacturer

Jiangsu Yongteli Machinery Co., Ltd. focuses on specialized pipe equipment manufacturing, accumulating rich experience in cold tube mill technology over four decades. Its products are recognized for stability, precision, and durability, serving clients in over 20 countries. The company’s commitment to R&D ensures that each machine, including the Steel Pipe Machine LD-100, adheres to international quality standards and adapts to evolving market demands.


Introduction to Steel Pipe Machine LD-100

The Steel Pipe Machine LD-100 is a high-performance cold rolling pipe machine tailored for medium-scale steel pipe production. It integrates advanced rolling technology, intelligent control systems, and robust structural design to optimize the pipe-forming process. Unlike conventional machines, the LD-100 minimizes material waste, reduces production cycles, and maintains consistent pipe quality—making it a cost-effective solution for manufacturers seeking to enhance productivity.


Product Features


Technical Performance


Exceptional Rolling Precision

The Steel Pipe Machine LD-100 achieves a rolling precision of ±0.05mm for pipe outer diameter and ±0.03mm for wall thickness, ensuring compliance with strict industry standards (e.g., ASTM, DIN). This precision is enabled by its high-precision roller bearings, servo-driven feeding system, and real-time thickness monitoring sensor—all of which work together to correct deviations during operation.


Wide Material Compatibility

The machine supports a broad range of raw materials, including carbon steel, stainless steel (304, 316L), alloy steel, and low-alloy high-strength steel. It can process steel billets with diameters ranging from 10mm to 100mm and lengths up to 6 meters, providing flexibility for producing various pipe types (e.g., seamless pipes, precision pipes).


Structural Advantages


Durable Core Components

Key components of the Steel Pipe Machine LD-100—such as rollers, gearboxes, and frames—are made of high-quality alloy steel (40CrNiMoA) heat treatment (quenching and tempering). This treatment enhances surface hardness (up to HRC 55-60) and wear resistance, extending the component service life to 5+ years under normal operation.


Modular Design for Easy Maintenance

The machine adopts a modular structure, where critical parts (e.g., rolling heads, lubrication systems) can be disassembled and replaced independently. This design reduces maintenance time by 40% compared to integrated machines, minimizing production downtime. Additionally, the machine is equipped with a self-diagnostic function that alerts operators to potential issues (e.g., abnormal temperature, insufficient lubrication) via a touchscreen interface.


Operational Efficiency


High Automation Level

The Steel Pipe Machine LD-100 features a PLC control system with a 7-inch color touchscreen, enabling one-click startup, parameter adjustment, and production data recording. Automated functions include material feeding, rolling speed regulation (5-20 m/min), and pipe cutting—reducing manual intervention and labor costs by 30%.


Energy-Saving Performance

With an optimized hydraulic system and frequency conversion motor, the LD-100 consumes 15% less energy than traditional cold rolling machines (average power consumption: 45 kW/h for continuous operation). It also uses a closed-loop lubrication system that recycles 90% of lubricating oil, lowering operational costs and environmental impact.


Applications


Industry-Specific Applications


Oil and Gas Industry

The Steel Pipe Machine LD-100 produces seamless steel pipes for oil and gas transmission, as its high precision and material compatibility meet the industry’s requirement for pressure resistance (up to 60 MPa) and corrosion resistance. These pipes are widely used in onshore and offshore pipelines, where reliability and safety are critical.

Construction Industry

In construction, the machine manufactures structural steel pipes for building frames, scaffolding, and HVAC systems. The pipes produced by the LD-100 have high tensile strength (≥450 MPa) and bending resistance, ensuring stability for large-scale construction projects (e.g., high-rise buildings, bridges).

Automotive Manufacturing Industry

The LD-100 supplies precision steel pipes for automotive components, such as chassis tubes, fuel pipes, and brake lines. Its ability to produce thin-walled pipes (minimum wall thickness: 0.8mm) with uniform dimensions aligns with the automotive industry’s demand for lightweight and high-strength parts.


End-Product Applications


Beyond industry use cases, the Steel Pipe Machine LD-100 supports the production of end products like:

• High-pressure water pipes for municipal engineering;

• Precision mechanical pipes for industrial pumps and valves;

• Stainless steel decorative pipes for furniture and architecture.


FAQ


What materials can the Steel Pipe Machine LD-100 process?

The Steel Pipe Machine LD-100 is compatible with multiple materials, including carbon steel, stainless steel (304, 316L), alloy steel, and low-alloy high-strength steel. It can handle raw steel billets with diameters from 10mm to 100mm and lengths up to 6 meters, making it suitable for diverse pipe production needs.


What is the typical production capacity of the LD-100?

Under standard operating conditions (processing carbon steel billets with a diameter of 50mm), the Steel Pipe Machine LD-100 achieves a production capacity of 300-500 kg/h. The capacity can be adjusted based on material type, pipe specifications, and rolling speed (ranging from 5-20 m/min).


Does YongTeLi offer technical support and after-sales service for the LD-100?

Yes. YongTeLi provides comprehensive after-sales support for the Steel Pipe Machine LD-100, including:

24/7 online technical consultation (via email: jskaizhongJx@qq.com or phone: +86-13336683488);
