Precautions:
1. When installing, the stainless steel elbow can be directly installed on the pipeline according to the connection method, and the installation is carried out according to the used position. Under normal circumstances, it can be installed at any position of the pipeline, but it needs to be sealed to prevent leakage and affect the normal operation of the pipeline.
2. Stainless steel elbow ball valves, globe valves and gate valves are only fully open or fully closed when they are used. They are not allowed to be used for flow adjustment to avoid sealing.
3. Long-term storage of stainless steel elbows should be inspected regularly. The exposed processing surface must be kept clean, cleaned of dirt, and stored neatly in a ventilated and dry place indoors. Stacking or open storage is strictly prohibited. Always keep the stainless steel elbow dry and ventilated, keep the device clean and tidy, and store it according to accurate storage methods.
Warm reminder: There are many things to pay attention to when stainless steel elbows are used. Users need to use them in a certain way, and use and maintain them in accordance with accurate and fair methods.
