**Curved Access Door** is an openable door or panel designed for curved structures, usually used in equipment, pipelines, containers or buildings that require regular inspection, maintenance or cleaning. Its core feature is that the door body fits perfectly with the curved surface (such as cylindrical, spherical or other irregular curved surfaces) to ensure structural integrity and aesthetics.

### **Main Features**
1. **Adaptability to curved surfaces**
- Customized according to the curvature of the application scenario (such as storage tanks, pipelines, ship cabins), seamlessly fit the curved surface, and avoid gaps or stress problems when traditional flat doors are installed on curved surfaces.
2. **Both lightness and strength**
- Made of lightweight metal (such as aluminum alloy, stainless steel) or composite materials, it not only ensures strength, but also facilitates frequent opening and closing.
3. **Sealing performance**
- Commonly used in high-pressure, waterproof or dustproof environments (such as chemical equipment, underwater facilities), equipped with sealing strips or locking devices to ensure airtightness.
4. **Quick opening and closing design**
- Hinges, slide rails or quick-release structures are used to facilitate personnel to quickly enter the equipment for maintenance.
