Pipeline steel clad plate is a perfect combination of carbon steel and stainless steel which features the excellent cost effectiveness ratio when being applied in industries like gas, oil, heat exchange, fluid pipe, chemical fertilizer pipe and so on. It can help you save the engineering cost greatly yet with better performance.
Overview
Pipeline Steel Clad Plate is innovative clad plates engineered by metallurgically bonding corrosion-resistant stainless steel with high-strength carbon steel. This dual-layer structure combines the cost-effectiveness of carbon steel with the superior corrosion resistance of stainless steel, making it an ideal solution for demanding applications in oil and gas transmission, heat exchange systems, chemical pipelines, and fluid transportation. Designed to meet GB standards, our clad steel plates ensure durability, safety, and long-term performance in harsh industrial environments.
Features
The thickness of the expensive corrosion resistant metal is made as thin as possible with the required strength being provided by the backing steel. The cladding ratio and the size of the clad plates can be produced to meet customer's requirements. In other words, flexibility of materials and made-to-order sizes of the cladding metal and backing steel makes it possible to reduce the material cost.
