The marine equipment industry requires high-strength, corrosion-resistant, and heavy-duty forming solutions for offshore platforms, marine pipelines, offshore pile pipes, ship supporting structures, and deep-sea engineering equipment. EZHONG provides integrated plate forming solutions including heavy plate leveling, cylinder rolling, and special-shape forming for marine weather-resistant steel, high-strength anti-corrosion steel, and special alloy materials.
Designed to meet the demanding operating conditions of marine engineering equipment, including seawater corrosion resistance, high-pressure resistance up to 80MPa, and harsh offshore environments, EZHONG equipment supports efficient processing for heavy plates with thicknesses ranging from 10mm to 300mm. The equipment helps manufacturers solve common industry challenges such as insufficient corrosion resistance, low forming precision, and unstable processing efficiency.
The final dimensional tolerance can be controlled within ≤±0.5mm, ensuring excellent structural stability, high corrosion resistance, and long-term operational reliability for offshore engineering applications. EZHONG equipment supports the manufacturing of large marine cylinders with diameters up to Φ10m and is widely used in offshore oil and gas development, marine engineering construction, and offshore infrastructure projects.
EZHONG offshore heavy plate rolling machines are specially developed for processing offshore platform cylinders, marine pipelines, pile pipes, and large marine structural components.
The equipment adopts corrosion-resistant and wear-resistant structural designs to support precision rolling for extra-thick plates and special alloy materials ranging from 10mm to 300mm in thickness. It delivers stable forming quality and excellent dimensional consistency for large marine engineering components operating in complex offshore environments.
Key Advantages
