How to Maintain Stainless Steel Valve Elbows?

In the pipeline system, the elbow is a pipe fitting that changes the direction of the pipeline. According to the angle, there are three commonly used angles of 45 ° and 90 ° 180 °. In addition, according to the needs of the project, other abnormal angles such as 60 ° are included. The materials of the elbow are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metal and plastic.

The characteristic strength and toughness indexes of stainless steel are the best among all kinds of steel. The most prominent advantage is corrosion resistance. Stainless steel must be used in corrosive occasions such as chemical papermaking. Of course, the cost is also higher. There are many things to pay attention to when using and maintaining stainless steel elbows. Users need to use them according to certain methods, and use and maintain them in an accurate and fair way. The precautions are as follows:

1. Long-term storage of stainless steel elbows should be checked regularly. The processing surfaces that are often exposed must be kept clean, to remove dirt, and stored neatly in a ventilated and dry place indoors. Stacking or open storage is strictly prohibited. Always keep the stainless steel elbows dry and ventilated, keep the cleaner clean and tidy, and store in accordance with accurate storage methods.

2. When installing, the stainless steel elbow can be directly installed on the pipeline according to the connection mode, and installed according to the position of use. Under normal circumstances, it can be installed in any position of the pipeline, but it needs easy inspection. Note that the flow direction of the stainless steel elbow should be upward from the bottom of the longitudinal disc, and the stainless steel elbow can only be installed horizontally. When installing stainless steel elbows, pay attention to the tightness to prevent leaks and affect the normal operation of the pipeline.

3. When using stainless steel elbow ball valves, globe valves, gate valves, they are only fully opened or fully closed, and they are not allowed to adjust the flow rate, so as to avoid erosion of the sealing surface and accelerated wear. The gate valve and the upper threaded stop valve have reverse seStainless steel elbows should be used with hand wheels. Do not use levers or other tools to avoid damage to the valve. The handwheel rotates clockwise to close, otherwise it opens.aling devices. The hand wheel is turned to the upper position and tightened to prevent the medium from leaking from the packing.

4. 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 not to bump the movement of the valve stem or cause leakage. 

5. The stainless steel elbow should always be kept clean during use. The transmission thread must be lubricated on schedule. When a fault is found, it should be stopped immediately and the cause should be found to clear the fault.
