Deep prefabrication and installation method for titanium pipeline

Abstract

The invention discloses a deep prefabrication and installation method for a titanium pipeline. The deep prefabrication and installation method comprises the following steps of: 1, building a three-dimensional model of the titanium pipeline through a BIM technology; 2, selecting an optimal three-dimensional model; 3, determining a proper transportation space according to the transportation conditions; 4, determining the shape and size of a welded junction of each section of titanium pipeline so as to be matched with an adjacent titanium pipeline; 5, prefabricating a titanium pipeline according to the three-dimensional model, and conducting marking; 6, performing mounting and welding; and 7, conducting checking and accepting after confirming that the requirements are met. The deep prefabrication and installation construction technology for the titanium pipeline is a technical method for deeply transferring the field workload to factory construction through deep prefabrication design in the earlier stage. The application of the technology can shorten the construction period of all pipelines with long purchasing period, special materials and high field quality control difficulty, so that the overall progress of a project is met.

Description

technical field [0001] The invention relates to the field of prefabricated installation of titanium pipelines. More specifically, the present invention relates to a deep prefabricated installation method for titanium pipelines. Background technique [0002] In the construction of petrochemical equipment, the engineering volume of process pipelines is very large, and the construction technology, quality and requirements for the skills of plumbers and welders are high. At present, the domestic construction and installation methods are mainly on-site. This method has on-site quality control. Difficulty, and the on-site environment is relatively complicated, the work interface is chaotic, and the work efficiency of workers is low. Contents of the invention [0003] In order to achieve these objects and other advantages according to the present invention, a deep prefabricated installation method for titanium pipelines is provided, comprising the following steps: [0004] Step...

AI Technical Summary

Problems solved by technology

[0002]In the construction of petrochemical equipment, the engineering volume of process pipelines is very large, and the construction technology, quality and requirements for the skills of pipe workers and welders are high. On-site construction and installation is the main method. This method has difficulty in on-site quality control, and requires a more complex on-site environment, chaotic work interface, and low worker efficiency.
