1. For long-term storage of plastic pipe caps, we need to inspect them promptly. Keep the exposed processing outer surface clean and free of dirt. Store them indoors in a dry place regularly, either stacked or outdoors. Always maintain the caps' dryness and ventilation, keeping them clean for proper storage.

2. Plastic pipe caps installed on steel pipes, which can be mounted at any position on the pipeline under normal circumstances, facilitating operation and inspection. Note the sealing integrity of the plastic pipe caps to prevent leaks and ensure normal operation.

3. Ball valves, gate valves, and globe valves equipped with plastic plug stoppers can only be fully open or fully closed; they are not to be used for flow regulation to prevent erosion of the sealing surfaces and accelerated wear. Both gate valves and upper threaded stop valves have reverse-sealing devices. By turning the handwheel to the upper position and tightening it, leakage of the packing medium can be prevented.

4. Use the handwheel for plastic pipe plug. Do not rely on levers or other items to prevent damage to valve parts. Clockwise rotation of the handwheel closes it, counter-clockwise opens it.
