How to maintain stainless steel elbow? 1. 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 in accordance with the accurate storage method. 2. 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 in the pipeline, but it requires easy-to-operate inspection. Note that the medium flow direction of the cut-off stainless steel elbow should be upwards under the vertical valve disc. The stainless steel elbow can only be installed horizontally. When installing stainless steel elbows, pay attention to the tightness to prevent leakage and affect the normal operation of the pipeline. 3. When using stainless steel elbow ball valves, globe valves and gate valves, they are only used for fully open or fully closed. They are not allowed to be used for flow adjustment to avoid erosion of the sealing surface and accelerated wear. There is an inverted sealing device in the gate valve and the upper threaded stop valve, and the handwheel is turned to the upper position and tightened to prevent the medium from leaking from the packing. 4. The stainless steel elbow should use a hand wheel. Do not use levers or other tools to avoid damage to the valve. Turn the handwheel clockwise to close, and vice versa to open. You must be fair when using it, and ensure accurate use methods and methods. 5. The bolts of the stainless steel elbow valve packing gland should be tightened evenly, and should not be pressed into a crooked state, so as to avoid bruising, hindering the movement of the valve stem or causing leakage. 6. The stainless steel elbow should always be kept clean during use, and the transmission thread must be lubricated on schedule. When a fault is found, it should be stopped immediately to find out the cause and clear the fault.
