Post-processing technology for manufacturing of large chemical oil pipelines

Abstract

The invention relates to a post-processing technology for manufacturing of large chemical oil pipelines. A post-processing device for manufacturing of the large chemical oil pipelines is used in the post-processing technology. The post-processing device for manufacturing of the large chemical oil pipelines comprises a base, clamping mechanisms, position adjustment mechanisms, guide mechanisms andangle adjustment mechanisms, wherein the clamping mechanisms are symmetrically arranged at the left and right ends of the base, the position adjustment mechanisms are arranged below the clamping mechanisms, the angle adjustment mechanisms are symmetrically arranged in the middle of the base front and back, and the guide mechanisms are arranged above the angle adjustment mechanisms. The post-processing technology can solve the problems that during beveling of the large oil pipelines at present, the oil pipelines are not fixed firmly and roll, consequently, the cut surfaces are not flat, for different oil pipeline laying paths, an angle formed after two oil pipelines are connected together changes, but an existing technology cannot accurately control the beveling angle, and poor sealing of oil pipeline connection at a later stage can be caused.

Description

technical field [0001] The invention relates to the field of pipeline processing, in particular to a post-manufacture process for large-scale chemical oil pipelines. 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 of pipe...

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, resulti
