Carbon steel flange use characteristics
Users need to use and maintenance. carbon steel flange according to certain methods and use them according to the exact method.The things to note are as follows:
1. Standard carbon steel flange valve packing gland bolts should be tightened evenly, should not be pressed into a smashing state, so as to avoid the movement of the valve stem or leakage.
2. The standard carbon steel flanges stored for a long time should be inspected on schedule. The exposed surface should be kept clean, dirt removed, and stored neatly in a place where the air is dry. It is strictly prohibited to be stacked or stored in the open air. The stainless steel flange is often kept dry and ventilated, and stored in an accurate storage method.
3. Standard carbon steel flange application hand wheel, do not use levers or other tools to avoid damage to the valve. The handwheel rotates clockwise to close, and vice versa. Use it accurately when using it. 4. When installing, the standard carbon steel flange can be directly connected to the pipeline according to the connection, and installed according to the position used. Under normal circumstances, it can be installed at any position of the pipeline, but it is easy to check the operation. Note that the flow direction of the stainless steel flange should be upward from the longitudinal valve. The stainless steel flange can only be installed horizontally. Stainless steel flanges should be carefully sealed during installation to prevent leakage and affect the normal operation of the pipeline.
5. For standard carbon steel flange ball valves, globe valves, gate valves, only fully open or fully closed, should not be used to adjust the flow, so as to avoid erosion of the sealing surface and accelerate wear. The gate valve and the upper thread stop valve have an inverted sealing device, and the hand wheel is screwed to the uppermost position to prevent the medium from leaking from the packing.
