When installing the equipment, the stainless steel elbow can be directly installed on the pipeline according to the connection method, and the equipment can be installed according to the application direction. In general, the equipment can be in any direction of the pipeline, but it needs to be easy to check the operation. Pay attention that the medium flow direction of the cut-off stainless steel elbow should be upward flow under the longitudinal valve disc, and the stainless steel elbow can only be used for horizontal equipment. Attention should be paid to the tightness of the stainless steel elbow when it is used in the equipment, so as to avoid leakage and affect the normal operation of the pipeline.

　　3. When the ball valve, globe valve and gate valve of stainless steel elbow are used, they are only used for full opening or full closing, and are not allowed to be used for regulating flow, so as to avoid erosion of sealing surface and accelerate wear. There are inverted sealing devices in gate valve and upper thread stop valve. When the hand wheel is screwed to the top, the leakage of medium from the packing can be prevented.
