What are the advantages of stainless steel elbows When installing stainless steel elbows, attention should be paid to the sealing, so as to prevent leakage and affect the normal operation of pipelines. Generally, it can be installed in any position of the pipeline, but it needs to be easy to operate the inspection, pay attention to cut-off stainless steel elbow media flow should be upward under the control valve disc, stainless steel elbow can only be installed horizontally. Ball valves, globe valves and gate valves with stainless steel elbows are used only for full opening or full closure, and flow regulation is not allowed, so as to avoid erosion of the sealing surface and accelerate wear and tear. There is an inverted sealing device in the gate valve and the upper thread globe valve, and the handwheel is rotated to the top to be welcomed by users. The main difference between stainless steel butt weld elbow and carbon steel butt weld elbow is the difference of material. The chemical composition of stainless steel elbow will maintain the important performance and operation value of elbow in practical use. There are many things to be noticed when using and maintaining stainless steel elbows. Users need to use them in a certain way and use and maintain them in an accurate and fair way. Stainless steel elbows do not produce corrosion, pitting, rust or wear. Stainless steel is still one of the most powerful building metal materials. Because stainless steel has good corrosion resistance, it can make structural parts permanent to maintain the integrity of Engineering design. Stamping elbow of stainless steel containing chromium is also a combination of mechanical strength and high extensibility. It is easy to process and manufacture parts and meets the needs of architects and structural designers. The welding rod used in stainless steel elbow should be kept dry when used. The Ti-Ca type should be dried for 1 hour at 150 C. The low hydrogen type should be dried for 1 hour at 200-250 C. (The coating can not be repeatedly dried, otherwise it is easy to crack and peel off), so as to prevent sticking oil and other dirt on the coating, so as to avoid increasing the carbon content of the weld and affecting the quality of the weld.
