Any item needs to be maintained and maintained, so that it can increase the time of use. If so, what is the maintenance work? The following specific instructions:

1. Ball valve of stainless steel elbow, stop valve, gate valve only when fully open or fully closed, do not allow 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.

Second, long-term storage of stainless steel elbows should be checked on schedule, often the exposed surface must be kept clean, remove dirt, neatly stored in a place where the room is dry and dry, no stacking or open storage. The stainless steel elbow is often kept dry and ventilated, the retainer is clean and tidy, and stored in an accurate storage method.

3. When installing, the stainless steel elbow can be directly installed on the pipeline according to the connection mode, and installed according to the position used. One

Under normal circumstances, it can be installed at any position of the pipeline, but it is necessary to facilitate the inspection of the operation. Note that the flow direction of the stainless steel elbow should be upward and downward from the longitudinal valve. The stainless steel elbow can only be installed horizontally. Stainless steel elbows should pay attention to the sealing during installation to prevent leakage and affect the normal operation of the pipeline. Commonly used grades of precipitation hardening stainless steel are 04Cr13Ni8Mo2Al and the like. It can be treated with precipitation hardening (also known as age hardening) to make it hard (strong) stainless steel.
