1results about How to "Accurate welding positioning" patented technology

The application discloses a kind of vertical assembly construction methods of steel bifurcated pipe, comprising the following steps: one, the tile of steel bifurcated pipe and crescent rib plate are made;Two, pre-assembled platform is set and steel bifurcated pipe lofting is carried out;Three, pre-assembled steel bifurcated pipe;Four, steel bifurcated pipe inner support is set;Five, steel bifurcated pipe disassembly;Six, steel bifurcated pipe transportation after disassembly;Seven, steel bifurcated pipe is assembled again.The application is welded positioning block on the tile of steel bifurcated pipe by pre-assembled segment of steel bifurcated pipe, and vertical assembly method is used to assemble steel bifurcated pipe, so that steel bifurcated pipe assembly difficulty is reduced, crescent rib plate and each tile assembly positioning, adjustment is simple;Tile assembly process is single, and deformation is small, and assembly quality is higher, after assembly, high-difficulty welding such as a lot of vertical welding and overhead welding is reduced, effectively improve the steel bifurcated pipe weld quality and efficiency;Positioning is accurate and stable using positioning block, greatly reduce the bifurcated pipe assembly difficulty again.
