In sectors such as petrochemicals, engineering machinery, steel structures, and special equipment manufacturing, thick-walled pipes are core components that withstand high pressure, heavy loads, and harsh environments. Their quality directly impacts the structural safety and service life of the overall equipment.
ST Machineries specializes in the R&D and manufacturing of high-end pipe production equipment. Our thick-walled pipe mill is designed to produce high-standard, high-strength pipe materials, with a core production range covering pipe diameters from 63 mm to 127 mm and wall thicknesses from 1.0 mm to 8.0 mm, providing reliable material production solutions for various industries.
Core Equipment Capability: The Fusion of Precision, Strength, and Efficiency
Our pipe production line incorporates advanced forming technology and precision welding processes (such as TIG welding or laser welding), ensuring excellent production performance across a broad specification range:
Wide-Range Precision Forming:
The mill possesses robust forming capability, enabling stable production of pipes from small to medium diameters (Φ63mm-Φ127mm). It effortlessly handles material processing from thin to thick walls (1.0mm-8.0mm), ensuring uniform pipe wall consistency.
High-Strength Welding Assurance:
Optimized for thick-walled pipe production characteristics, the welding system achieves deep fusion across the full thickness range. Weld seam strength can reach over 95% of the base material, meeting the mechanical requirements for applications like high-pressure systems and structural support.
Excellent Straightness and Roundness:
Equipped with multiple sizing and straightening units, the line ensures every finished steel pipe possesses superior straightness and roundness, laying a solid foundation for subsequent precision assembly and machining.
Flexible Production Configuration:
The production line can be configured to process various materials like carbon steel and high-strength low-alloy steel based on customer needs. Optional modules such as online inspection and automatic length cutting are available to enhance automation levels and product consistency.
