| titleOfInvention | Method for manufacturing composite welding austenitic stainless steel pipe for fluid transportation |
| abstract | The invention discloses a manufacturing method of a composite welding austenitic stainless steel pipe for fluid transportation, which comprises the following steps: s1: preparing a plate, namely performing ultrasonic flaw detection on the plate to realize accurate control on the quality of the raw material; then measuring the width of the plate according to the requirements of a process planning card, and cutting the plate raw material; s2: and (4) edge planing, and selecting and processing different groove forms according to the plates with different thicknesses. S3: bending; s4: shaping and prewelding; s5: and (6) welding. Carry out multilayer multiple pass welding operation with austenite stainless steel after the plastic prewelding, multilayer multiple pass welding operation includes in proper order: plasma welding, submerged arc welding, argon arc welding capping and repair welding. S6: and (6) heat treatment. Through the mode, the manufacturing method of the composite welding austenitic stainless steel pipe for fluid conveying can improve the production efficiency and reduce the production cost, and the surface quality qualification rate and the quality product rate of the pipeline welded junction are greatly improved by adopting the multilayer multi-pass welding technology, so that the production efficiency is improved. |
