Embodiment Construction
[0040] Such as figure 1 — Figure 6 Shown, the present invention adopts following steps:
[0041] The first step: if figure 1As shown, the preparatory work includes: manufacturing several steel pipe conduits 1 and steel pipe tie bars (steel pipe pipes 1 and steel pipe tie bars are all formed by plate cutting, rolling, welding and lengthening), wherein, after lengthening The two ends of the steel pipe tie bars are cut through the saddle mouth; this embodiment is to assemble and prefabricate a single pipe piece, including: two steel pipe pipe pipes 1, several steel pipe horizontal tie bars 2 and corresponding steel pipe inclined tie bars 3; (1) according to the construction drawings First place the pier at the set position, and then place several steel pipe conduits 1 on the pier; (2) Then, use a pan ruler to measure the front end, end distance and diagonal distance of several steel pipe conduits 1; after confirming that it is correct , fix the steel pipe conduit 1 and the pi...

The invention discloses an assembling technology for steel-pipe-end saddles. The assembling technology includes the following steps that 1, preparatory work is carried out; 2, outer walls of to-be-assembled pipe openings are polished to be smooth; 3, corresponding positions of steel-pipe horizontal tie pieces are adjusted; 4, the saddles of the two ends of the steel-pipe horizontal tie pieces areadjusted to be relatively coincident with crossed steel-pipe guiding pipes; 5, the saddles are cut and repaired, and front-end horizontal steel pipe tie pieces are completely assembled; 6, tail-end steel-pipe horizontal tie pieces are assembled; 7, then back-end steel-pipe slant tie pieces are assembled; 8, weld points of the steel-pipe guiding pipes and cup supports are excised and polished to besmooth. According to the assembling technology for the steel-pipe-end saddles, operation is easy and convenient, the problem that saddle pairing is troublesome is solved, and the working efficiency of steel-pipe-end saddle assembling is improved; rating per machine per team and labor are greatly reduced, and the production cost is reduced.
Description
technical field [0001] The invention relates to a steel pipe, in particular to an assembly process for a saddle at the end of a steel pipe, and belongs to the field of offshore oil engineering construction. Background technique [0002] In the process of offshore oil development, jackets and oil platforms need to be built. The main structure of the jacket and oil platform is mainly composed of many pieces of steel pipe ties (steel pipe ties are divided into two types: horizontal ties and inclined ties. The steel pipe ties are cut through the saddle openings at both ends in advance) in a horizontal manner , A space frame structure formed by connecting several pieces of conduits (steel pipes with relatively large diameters) in an inclined manner. [0003] At present, the main structures of jackets and oil platforms are prefabricated by single-piece assembly, and then multiple single-piece assemblies are assembled and connected. Because the saddle openings at both ends of the...
