Steel Pipe Bend 323.9*12.7 High impulse resistance, light weight
The bend is a complete set of bending mold for bending, divided into two processes: cold simmer and heat pushing. No matter which kind of machine, equipment and pipeline, most of them are used in bends, mainly for oil transmission, gas transmission, infusion, etc.
During pure bending, under the action of external force away from M, the outer arm wall is reduced by tensile stress & 1 and the inner compression stress. By thickening, the resultant N1 and N2 change the pipe cross section. Based on this factor, the main reason for the decline of bending quality is RX and SX. Therefore, in GBJ235—82, the RX values and outside the thinning volume are clearly stipulated, in order to control the value of RX and SX, so as to ensure the quality.
