• With a precise square section of 0.24in×0.24in (6×6mm), it fits accurately into compatible equipment, guaranteeing optimal sealing performance.
• Each roll has a net weight of 7kg, providing a substantial quantity that is ideal for large-scale equipment or multiple sealing tasks in demanding industries.
• It exhibits excellent resistance to acid, alkali, and molten metals such as zinc, ensuring reliable sealing even in the presence of harsh chemical media.
• Its black color allows for easy visual inspection, enabling quick identification of wear or damage in sealing applications.
• It is specifically designed for use in a wide range of industries including chemical, petroleum, pharmaceutical, food, sugar, pulp, paper, and power, where sealing under high-temperature, high-pressure, and corrosive conditions is essential.

Usage Instructions

1. Ensure the equipment (valves, pumps, reactors) is shut down and isolated from all power sources before beginning the installation process.
2. Remove the old packing (if present) and thoroughly clean the packing chamber to remove any debris, residue, or old sealing material.
3. Cut the JIMING graphite nickel wire packing to the required length, ensuring clean, square cuts for optimal sealing. Use appropriate tools suitable for cutting this composite material.
4. Install the packing into the packing chamber, layer by layer, ensuring each layer is properly seated and aligned. For square section packing, ensure the corners fit snugly into the chamber.
5. Adjust the packing gland to achieve the desired sealing tightness. This packing requires careful adjustment to balance sealing efficiency and friction levels.
6. After installation, conduct a leak test under operating conditions. Monitor the seal for any signs of leakage or abnormal operation. Adjust the gland as necessary during initial operation, taking care not to over-tighten which could cause excessive wear.

Applicable Scenarios
