Problems solved by technology

[0005] The present invention can solve the problem that when the existing petroleum pipelines are transported, the volume of the pipelines is large, and the pipelines cannot be assembled and spliced ​​effectively, resulting in poor transportation effect and inconvenient transportation of the pipelines, which affects the use effect of the pipelines, and at the same time When the existing oil pipeline is in use, the sealing effect of the pipeline is poor, and the insulation performance of the pipeline is low, so that the pipeline cannot effectively adapt to the low temperature environment and reduce the transportation efficiency of oil.

Abstract

The invention relates to an assembled petroleum pipeline and its splicing and installation method, comprising a fixed pipeline, a connecting flange and a connecting device. The fixed pipeline is in a cylindrical hollow structure, and a stepped groove is arranged on the outside of the fixed pipeline. Adjacent fixed pipelines The pipes are connected by a connecting device, and a connecting flange is installed on the outside of the fixed pipe at the end, and threaded holes are uniformly installed on the connecting flange. The present invention can solve the problem that when the existing petroleum pipelines are transported, the volume of the pipelines is large, and the pipelines cannot be assembled and spliced ​​effectively, resulting in poor transportation effect and inconvenient transportation of the pipelines, which affects the use effect of the pipelines, and at the same time When the existing oil pipelines are in use, the sealing effect of the pipelines is poor, and the insulation performance of the pipelines is low, so that the pipelines cannot effectively adapt to the low temperature environment and reduce the transportation efficiency of oil.

Description

technical field [0001] The invention relates to the field of petroleum transportation pipeline processing, in particular to an assembled petroleum transportation pipeline and a splicing installation method thereof. Background technique [0002] Petroleum is mainly used as fuel oil and gasoline, which constitute one of the most important secondary energy sources in the world. Petroleum is also a raw material for many chemical industry products such as solvents, fertilizers, pesticides and plastics. In fact, petroleum is a non-renewable raw material. [0003] At present, the existing oil pipelines usually have the following defects when they are in use: 1. When the existing oil pipelines are transported, the pipelines are bulky, and the pipelines cannot be assembled and spliced ​​effectively, resulting in the failure of the pipelines. The transportation effect is poor and the transportation is inconvenient, which affects the use effect of the pipeline; 2. When the existing o...
