| Processing technology of stainless steel thin-walled seamless elbow, whose character is in stainless steel pipe in the process of advancing automatic pipe bender bend mold with the pipe in the pipe with internal diameter equal to the size of the lining, and then set the stainless steel pipe in the bend mould, and then through the hydraulic press for stainless steel pipe to elbow mold in advance until the molding. Due to the present invention in the stainless steel pipe to elbow mold in the process set up within the steel pipe lining, the lining of steel pipe inner diameter size and equal, and the bushing inside also has a reinforcement to increase the intensity of squeezed bushing.In this way, the steel pipe bend forming process, the tube wall if not under the condition of the hydraulic propulsion, bushing, within a block wall to extrusion, make wall will not deformation in bend forming process.The product successfully trial-produced, fills the blank of the large diameter thin-walled stainless steel seamless elbow in our country, change the large diameter thin-walled stainless steel seamless elbow beyond domestic production dependent on imports, for the country save foreign exchange, reduced the cost for the user. |
