The main difference between stainless steel elbows and carbon steel elbows lies in the different materials. The chemical components contained in the elbow pipe can prevent the surface of the elbow pipe from rusting or corroding for a long time. In piping systems, elbows are pipe fittings for redirecting pipes. Depending on the Angle, there are three commonly used elbows, namely45°and90°180°Including other unusual elbows, for example60°It depends on your engineering requirements.
How to maintain stainless steel elbows?
1Stainless steel elbows that have been stored for a long time should be inspected regularly. Exposed treated surfaces should be kept clean and tidy and stored in a well-ventilated and dry indoor area. Stacking or storage is strictly prohibited. Outdoor activities. Keep the stainless steel elbows dry and well-ventilated, maintain the equipment clean and tidy, and store them in accordance with the correct storage methods.
2During installation, the stainless steel elbow can be directly installed in the pipeline according to the connection method and installed according to the usage position. Under normal circumstances, it can be installed at any position 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 the air tightness to prevent leakage and affect the normal operation of the pipeline.

3When 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 regulate the flow rate to prevent corrosion of the sealing surface and accelerate wear. Gate valves and top screw valves are equipped with reverse sealing devices. The handwheel can be turned to the top position to tighten and prevent the medium from leaking out of the packing.
4For stainless steel elbows, please use the handle. 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. When using it, fairness must be ensured, and the correct usage and methods need to be guaranteed.
5The packing seal bolts of the stainless steel pipe fittings should be tightened evenly. Do not push them into the bending position to avoid scratches, which may hinder the movement of the valve stem or cause leakage.
6During use, the stainless steel elbow should always be kept clean and the transmission thread should be lubricated as required. If a malfunction is detected, the operation should be stopped immediately and the cause of the malfunction identified.
