High quality stainless steel elbow not only saves space and weight, but more importantly, they prevent joint leakage and provide excellent sealing performance. Due to the smaller diameter of the seal, the size of the compact flange is reduced, reducing the diameter of the seal, which will reduce the cross-section of the sealing surface. Then replace the flange gasket with a sealing ring to match the sealing surface with the sealing surface.

What are the inspection methods for high quality stainless steel elbow:

Tensile test: measure stress and deformation, determine the strength (YS, TS) and plasticity index (A, Z) of the material, longitudinal and transverse sample tube sections, arc, round sample (￠10, ￠12.5) small diameter, Thin-walled large-diameter, thick-walled calibration distance.

Impact test: CVN, notch C type, V type, work J value J/cm2 standard sample 10×10×55 (mm) non-standard sample 5×10×55 (mm). Finally, perform the process performance test of the unshown steel pipe, including flattening test and ring tension test, flattening test: round specimen C-shaped specimen (S/D>0.15) H=(1+2)S/(∝ +S/D) L=40～100mm, the coefficient of deformation per unit length=0.07～0.08. Ring pull test: L=15mm, no cracks are qualified.

High quality stainless steel elbow has certain corrosion resistance (oxidizing acid, organic acid, cavitation), heat resistance and wear resistance. It is usually used in power plants, chemical, petroleum and other industries.
