Post-processing system for manufacturing large-scale chemical oil pipelines

Abstract

The invention relates to a post-processing system for manufacturing large-scale chemical oil pipelines. The system comprises a base, clamping mechanisms, position adjusting mechanisms, guiding mechanisms and angle adjusting mechanisms, the clamping mechanisms are symmetrically arranged at the left end and the right end of the base, the position adjusting mechanisms are arranged below the clampingmechanisms, the angle adjusting mechanisms are symmetrically arranged front and back in the middle of the base, and the guide mechanisms are arranged above the angle adjusting mechanisms. According tothe system, the problems that in the prior art, when the large-scale oil pipelines are beveled, the fixing of the oil pipelines is not firm and the oil pipelines roll to cause uneven cutting planes,according to different oil pipeline laying paths, an angle formed by connecting two sections of the oil pipelines together changes, the beveling angle cannot be accurately controlled in the prior artcan lead to poor connection and sealing of the oil pipelines in the later period are solved.

Description

technical field [0001] The invention relates to the field of pipeline processing, in particular to a large-scale chemical oil pipeline manufacturing post-processing system. Background technique [0002] Pipeline transportation is a way of transporting fluid goods by pipeline, and the goods are usually liquid and gas. It is a special part of mainline transportation in the unified transportation network. Pipeline transportation of petroleum products is more expensive than water transportation, but still cheaper than railway transportation. . The transportation of oil through pipelines is not only large in volume, continuous, rapid, economical, safe, reliable, stable, low in investment, small in land occupation, and low in cost, but also can realize automatic control. Pipeline transportation can save the transfer of water or land transportation, shorten the transportation cycle, reduce transportation costs, and improve transportation efficiency. The current development trend ...

AI Technical Summary

Problems solved by technology

[0003] One of the post-manufacture treatments of large oil pipelines is to obliquely cut the pipeline to deal with the inevitable obstacles on the pipeline laying path, which needs to be bent and laid. There are still the following problems in the oblique cutting of large oil pipelines: first, in the case of large When the oil pipeline is cut obliquely, the fixing of the oil pipeline is not reliable, and the oil pipeline rolls, resulting in uneven cutting surface, which has an impact on the later connection and sealing; secondly, according to the different laying paths of the oil pipeline, two sections of the oil pipeline are connected together The formed angle changes, and the existing technology has the problem of being unable to accurately control the bevel angle, which will also lead to the problem of poor sealing of the oil pipeline connection in the later stage
