The main technical characteristics of SSAW steel pipe

Spiral Submerged Arc Welded (SSAW) steel pipes are known for their distinctive production process and technical advantages. Below are the key characteristics that define SSAW steel pipe production.

Uniform Deformation and Minimal Residual Stress
During the molding process, the steel plate undergoes uniform deformation, ensuring minimal residual stress and no surface scratches. This results in SSAW steel pipes having a higher degree of flexibility in terms of diameter and wall thickness. Specifically, SSAW is particularly advantageous in the production of high-strength, thick-walled pipes, including small and medium-diameter thick-walled pipes, where it excels compared to other methods in meeting user requirements.

Advanced Double-Sided Submerged Arc Welding (SAW)
The use of double-sided submerged arc welding technology allows welding to be done at the optimal position, reducing common issues such as edge errors, welding deviations, and defects. This ensures higher control over welding quality, making the process more reliable.

Comprehensive Quality Inspection
The entire production process of SSAW steel pipes is equipped with effective detection and monitoring systems to ensure 100% quality inspection. This guarantees the consistency and reliability of the final product, ensuring that every pipe meets the required standards.

Real-Time Data Monitoring and Control
All equipment in the production line is networked with a computer data acquisition system, enabling real-time data transmission. The production parameters are centrally controlled via a central control room, allowing for precise monitoring and adjustment of key process variables to optimize pipe quality.

Strict Raw Material Inspection
The raw materials used in SSAW pipe production, including coils, wires, and melts, undergo strict physical and chemical inspections before they are allowed into the production process. This ensures the quality and suitability of the materials for welding and further processing.

Efficient Strip Processing
The steel strip undergoes comprehensive preparation before forming, including leveling, trimming, planing, surface cleaning, and pre-bending. This ensures that the strip is in optimal condition for the welding and forming processes, reducing defects and improving the quality of the final product.

Effective Steel Strip Transportation Control
The pressure on both sides of the conveyor is monitored and controlled using electric contact manometers, ensuring smooth and efficient transportation of the steel strip. This control helps prevent issues during the forming stage and improves overall production efficiency.

Roller Shape Control
The process utilizes either external or internal roller control to shape the steel strip. This step is crucial for maintaining the correct geometry and alignment of the strip as it transitions into the pipe form.

Welding Control System
A dedicated welding control device ensures that the welds meet strict quality requirements. It carefully monitors and controls the pipe diameter, alignment, and the weld seam, further enhancing the consistency and precision of the final product.

Stable Welding Quality with Lincoln Welders
To maintain stable and high-quality welding, American Lincoln welders are used for both internal and external welding. The single-wire or double-wire submerged arc welding process ensures that the pipe is welded to the highest standards, providing both strength and reliability.

These technical characteristics make SSAW steel pipes highly versatile, durable, and suited to a wide range of applications, particularly where high-quality, thick-walled pipes are required. The combination of advanced technology, stringent quality control, and precision welding ensures that SSAW steel pipes meet the demanding needs of various industries.
