Heavy chemical industry
Hydraulic Cylinders are specialized products designed to meet the unique demands of the heavy chemical sector.
#### **1. Product Overview**
Heavy-duty chemical industry hydraulic cylinders are specially designed for extreme working conditions such as high corrosion, high temperature, and high pressure in the chemical industry. They are made of special materials and through unique processes to ensure long-term stable operation in environments with strong acids, strong alkalis, high dust, and flammable and explosive substances. They are applicable to key processes such as the lifting of reactor covers, valve control, material conveying equipment, and presses.

#### **2. Core Features**
- **Corrosion Resistance**
- Cylinder Material: Stainless steel (such as 304/316L), nickel-plated alloys, or surface coating treatments (hard chrome, ceramic coating).
- Seals: Fluororubber (FKM), polytetrafluoroethylene (PTFE), and other materials resistant to chemical media.
- **High-pressure Load-bearing**
- Working pressure range: **20-40 MPa** (customizable for higher pressure grades).
- Multi-layer reinforced cylinder wall design, highly resistant to impact.
- **High-temperature adaptability**
- Operating temperature: **-40℃ to +200℃** (High-temperature type available with heat-resistant seals).
- **Explosion-proof and Safety**
- Compliant with ATEX/ISO standards, suitable for flammable and explosive environments (such as oil and gas chemical scenarios).
- Equipped with an internal safety valve or buffer device to prevent overload or uncontrolled movement.
- **Low-maintenance design**
- Self-lubricating bearings, dust-proof rings and modular sealing structures reduce downtime for maintenance.

#### **3. Typical Application Scenarios**
- **Reactors/Pressure Vessels**: Power execution for top cover lifting and locking devices.
- **Pipeline Valve Control**: High-precision regulation of chemical fluid flow.
- **Material Handling Equipment**: Hydraulic systems for forklifts and lifting platforms.
- **Filter Presses/Centrifuges**: High-pressure liquid separation or solid-liquid separation operations.
- **Special Equipment**: Hydraulic mechanical arms and conveyor belt drives in explosion-proof environments.
