The main difference between stainless steel elbows and carbon steel elbows is the difference in materials. The chemical composition contained in the elbow can prevent the surface of the elbow from rusting or corroding for a long time. In the piping system, the elbow is a pipe fitting that redirects the pipe. Depending on the angle, there are three commonly used elbows, 45° and 90°180°, including other unusual elbows, such as 60°, depending on your engineering needs. How to maintain stainless steel elbow? 1. The stainless steel elbows stored for a long time should be checked regularly. The exposed and treated surface should be kept clean, clean, and stored in a well-ventilated and dry place indoors. Stacking or storage is strictly prohibited. Outdoor activities. Keep the stainless steel elbow dry and ventilated, keep the equipment clean and tidy, and store it according to the correct storage method. 2. During installation, the stainless steel elbow can be directly installed in the pipeline according to the connection method, and installed according to the use position. Normally, it can be installed 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 valve disc. Stainless steel elbows can only be installed horizontally. When installing stainless steel elbows, please pay attention to air tightness to prevent leakage and affect the normal operation of the pipeline. 3. When using stainless steel elbow ball valves, glove valves and gate valves, they can only be fully opened or fully closed. It cannot be used to adjust the flow rate to prevent corrosion of the sealing surface and accelerated wear. The gate valve and the top screw valve have reverse sealing devices, and the handwheel can be turned to the top position to tighten and prevent the medium from leaking out of the packing. 4. For stainless steel elbows, please use handles. Do not use joysticks or other tools to prevent damage to the valve. Turn the handwheel clockwise to close it, and vice versa to open it. It must be used fairly, and correct usage and methods must be ensured. 5. Tighten the packing and sealing bolts of stainless steel pipe fittings evenly, do not push them into the bent position, so as not to cause scratches, hinder the movement of the valve stem or leak. 6. During use, the stainless steel elbow should always be kept clean, and the transmission thread should be lubricated as required. If a malfunction is found, stop immediately and find out the cause of the malfunction. Precautions for stainless steel elbow 1. At the same time, stainless steel elbow can be directly installed on the pipeline through the connection method and installed according to the use position. Under normal circumstances, it can be installed anywhere in the pipeline, but it must be sealed to prevent leakage and affect the normal operation of the pipeline. 2. When using stainless steel elbow ball valves, glove valves and gate valves, they can only be fully opened or fully closed. It cannot be used for flow control to avoid sealing. 3. The long-term storage conditions of stainless steel elbows should be checked regularly. Bare treated surfaces should be kept clean, clean, and stored in a well-ventilated and dry place indoors. Stacking or storage is strictly prohibited. Outdoor activities. Keep the stainless steel elbow dry and ventilated, keep the equipment clean and tidy, and store it according to the correct storage method.
