2026-05-11 17:08
As application scenarios for stainless steel composite tubes continue to expand, market demands for enhanced protective performance and structural stability are steadily rising. The bimetallic composite structure—featuring a stainless steel outer layer and a galvanized inner layer—has emerged as an industry mainstream choice due to its dual corrosion resistance and high strength. The core competitiveness of this structure relies heavily on the technical support provided by the Simultaneous Omnidirectional Extrusion Cladding process.
Unlike traditional composite processes that often suffer from delamination and peeling, the Simultaneous Omnidirectional Extrusion Cladding process utilizes high-precision automated equipment to achieve seamless bonding between the outer stainless steel and the inner galvanized substrate. During production, the inner galvanized substrate undergoes surface activation treatment to completely remove oxide layers and impurities, ensuring interface cleanliness for bonding. Subsequently, the pre-treated stainless steel outer billet is precisely fitted, and 360°uniform extrusion force is applied via an omnidirectional extrusion die. Coupled with precise temperature control, this induces plastic deformation in both materials, forming a robust mechanical bond without any adhesives. This fundamentally eliminates the risk of delamination during later use.
For these specific stainless steel composite tubes, the advantages of this process are particularly prominent:
Precision & Aesthetics:It allows precise control over the cladding accuracy of the stainless steel outer layer, ensuring a smooth, flat surface. This preserves the aesthetic appeal of stainless steel while enhancing external corrosion resistance.
Inner Protection:It effectively protects the integrity of the inner galvanized layer, preventing damage during manufacturing. This maximizes the inner wall’s protective properties and anti-scaling advantages, realizing a true "external anti-corrosion, internal protection" dual effect.
Industry experts note that the mature application of the Simultaneous Omnidirectional Extrusion Cladding process not only elevates the product quality of stainless steel composite tubes but also reduces production energy consumption and costs. This advancement propels the composite tube industry toward more efficient, high-quality, and energy-saving development. Looking ahead, with continuous process optimization, these stainless steel composite tubes are poised to achieve application breakthroughs in more high-end scenarios, becoming the preferred alternative to single-material tubing systems.
