Application of Stainless Steel Exhaust Intake

When the large diameter elbow is bent, the outer arm wall of the intermediate layer is thinned by tensile stress under the effect of external force distance M, while the inner arm is subjected to compressive stress. The resultant force N1 and N2 changes the cross section of the pipe. Based on this factor, RX and SX are the main reasons for the quality decline of the elbow. Therefore, GBJ235-82 clearly stipulates the RX value under various pressures and other conditions as well as the amount of thinning outside, in order to control the VALUES of RX and SX, so as to ensure the quality.
