How to store plastic pipe stoppers

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, stop valves, and gate valves with plastic pipe plugs can only be fully open or fully closed; they are not to be used for regulating flow to prevent erosion of the sealing surfaces and accelerated wear. Gate valves and upper threaded stop valves are equipped with reverse-sealing devices. By rotating the handwheel to the upper position and tightening it, leakage of the packing medium can be prevented.

4. Use the handwheel to block the plastic tube. Do not rely on levers or other items to prevent damage to valve components. The handwheel is closed when turned clockwise, and open otherwise.
