Installation and Maintenance Instructions for Sanitary Steel Pipes:
1. Sanitary steel pipes should be stored in a dry, well-ventilated indoor environment, with both ends of the pipe sealed to prevent dust.
2. For long-term storage, regular inspections should be conducted, and oil should be applied to the machined surfaces to prevent rust.
3. Before installation, carefully check that the markings on the sanitary steel pipes match the usage requirements.
4. During installation, clean the inner cavity and sealing surfaces, check that the packing is properly compressed, and ensure that the connecting bolts are tightened evenly.
5. Sanitary steel pipes should be installed in their permissible working positions, while ensuring ease of maintenance and operation.
6. During use, sanitary steel pipes should not be... 7. Gate valves should be partially opened to regulate flow, but to prevent damage to the sealing surface at high medium flow rates, they should ideally be fully open or fully closed.
8. When opening or closing, the handwheel should be rotated without the aid of other auxiliary levers.
9. Transmission components should be lubricated regularly. Sanitary steel pipes should be frequently lubricated on rotating parts, and the trapezoidal thread of the valve stem should be coated with oil.
10. After installation, regular maintenance is required. Clean the internal cavity of dirt and inspect the sealing surfaces and the wear of the valve stem nut.
11. A set of scientific and correct installation operation standards should be in place. During maintenance, a sealing performance test should be conducted, and detailed records should be kept for future reference.
