The Core Pillar of Precision Manufacturing:
WOMIC STEEL GROUP Cold Drawn Seamless Pipe Solutions Empowering Global Industrial Innovation
High-Quality Hydraulic Cylinder Precision Cold Drawn Seamless / Welded Steel Pipe / Steel Tube
In the pursuit of precision and reliability in industrial fields, cold drawn seamless pipes have become the “invisible backbone” of industries such as automotive, aerospace, and energy. With decades of technological expertise, WOMIC STEEL GROUP helps global customers break engineering limits with high-precision, high-strength, and corrosion-resistant cold drawn seamless pipe products.
Why Choose Cold Drawn Seamless Pipes?
Cold drawn seamless pipes use a unique cold working process to pull solid metal billets into seamless hollow structures, completely eliminating the weakness of welded seams. Their advantages far surpass those of traditional welded pipes:
Unmatched Strength: The grain structure is densified, enhancing tensile strength by more than 30%, capable of withstanding extreme pressure environments.
Millimeter-Level Precision: Inner and outer diameter tolerances are precise to ±0.1mm, meeting the needs for precision transmission and assembly.
All-Environment Corrosion Resistance: Utilizing high-purity alloy materials and surface treatment technologies, they adapt to corrosive environments like chemicals and marine conditions.
Lightweight Design: Weighing 15% less than welded pipes of the same specification, significantly reducing equipment energy consumption.
WOMIC’s Core Technology: Lean Manufacturing from Raw Material to Finished Product
We ensure the quality benchmark of every pipe with 7 key processes:
Selective Raw Materials: Using high-quality steel billets from Baosteel, Hengyang, TPCO, etc., with spectral testing to ensure material composition meets standards.
Intelligent Piercing: Precision-controlled temperature piercing technology eliminates internal stress concentration, establishing structural stability.
Multi-Stage Cold Drawing: Achieving optimal balance of wall thickness uniformity and surface smoothness through 12 progressive cold drawing stages.
Customized Heat Treatment: Tailored annealing/normalizing processes based on customer requirements, precisely controlling mechanical properties.
Zero Defect Detection: Automated flaw detection throughout the entire process (eddy current + ultrasonic), with a defect detection rate of 99.99%.
Eco-Friendly Surface Treatment: Offering 8 anti-corrosion options, including galvanizing and powder coating, complying with RoHS and REACH standards.
Intelligent Storage and Logistics: Constant temperature and humidity warehouses with custom shockproof packaging to ensure zero loss during global delivery.
