PRODUCT ADVANTAGES AND QUALITY ASSURANCE
- Precision Manufacturing: Produced using equipment such as CNC slant-bed lathes, CNC deep-hole compound boring machines, and CNC honing machines. Every cylinder undergoes a 1.5× working pressure test and a pressure holding test. For cylinders equipped with a control valve group, we simultaneously set the pressure and flow for the valve group.
- Enhanced Corrosion Resistance: The entire cylinder is blast-cleaned to remove rust, then coated with marine-grade anti-corrosion paint—ensuring it withstands harsh marine conditions.
- Post-Sales Support: We provide a 1-year quality warranty. If quality issues occur, free replacement is available to keep your operations running smoothly.

For non-standard hatch cover needs, we provide full-size customization services:
- Bore Size Range: 50–500+ mm (supports multiple installation methods, including eye-type and flange-type).
- Material Choices: Carbon steel + chrome plating, stainless steel + chrome plating, alloy steel + laser cladding, etc.
- Seal Configuration: Adopts seals from internationally renowned brands (NOK, SKF, PARKER, MERKEL, TECHNOLAN, KASTAS) to ensure long-term sealing performance, stability, and anti-aging properties.
