There are many things to keep in mind when using and maintaining stainless steel elbows. Users must use them in a specific way and use and maintain them in an accurate and fair manner. Please pay attention to the following: 1. Stainless steel elbows that have been stored for a long time should be inspected as planned. Bare treated surfaces should always be cleaned, cleaned and stored in a well-ventilated, dry indoor place. Stacking and open storage are prohibited. Always keep the stainless steel elbow dry and ventilated, keep the equipment tidy, and store it in accordance with the correct storage method. 2. Equipment, the stainless steel elbow can be directly connected to the pipeline according to the connection method, or the equipment can be connected according to the application position. Normally, the equipment can be placed anywhere in the pipeline, but a simple inspection is required. The middle flow direction of the cut-off stainless steel elbow must be upward from the vertical disc. Stainless steel elbows can only be used for horizontal equipment. Stainless steel elbows need to pay attention to the air tightness of the equipment to prevent leakage and affect the normal operation of the pipeline. 3. When using stainless steel elbow ball valves, glove valves and gate valves, only use them when they are fully open or fully closed. The flow cannot be adjusted to prevent corrosion of the sealing surface and accelerate wear. The gate valve and the top screw valve have reverse sealing devices, which can be tightened by turning the handwheel to the top position to prevent the medium from leaking from the packing. 4. The hand wheel should use stainless steel elbow. Do not rely on levers or other tools to prevent damage to the valve. Turn the handwheel clockwise to close it. Otherwise it is open. 5. Tighten the stainless steel elbow packing seal bolts evenly, do not push them into the bent position. Do not scratch, obstruct the movement of the valve stem or leak. 6. During use, the stainless steel elbow should always be cleaned, and the transmission thread should be as smooth as possible. If a defect is found, it should stop immediately to determine the cause and eliminate the defect.
