Construction process of high-pressure stainless steel acetylene filled tube

Abstract

The invention discloses a construction process of a high-pressure stainless steel acetylene filled tube. The process comprises following steps of firstly, cutting, discharging and numbering of a mother tube; secondly, groove preparation; thirdly, sub tube discharging according to the mother tube; fourthly, sub tube outer burr grinding; fifthly, sub tube filling; sixthly, sub tube leveling; seventhly, sub tube inner grinding; eighthly, filling, shaping and sub tube spot welding; ninthly, assembling of straight tube segments; ninthly, pipe fitting and flange assembling; eleventhly, pipe fittingpadding filling; twelvethly, pipefitting industrialization prefabrication. According to the process, the straight pipe segments are wholly filled, a filling platform is developed, a whole filling method is adopted for construction, and the problems that due to one-by-one sub tube filling, the efficiency is low, and the quality is poor are solved; sub tube whole filling is carried out, after filling, sub tube arranging interval quality is good, staggered collapsing is avoided, the schedule is greatly improved, and the traditional straight pipe segment filling construction process is thoroughlychanged.

Description

technical field [0001] The invention relates to the technical field of acetylene filling pipes, in particular to a construction process for high-pressure stainless steel acetylene filling pipes. Background technique [0002] In recent years, China's BDO production capacity has shown a trend of small-scale to large-scale development. The core process of BDO equipment is acetylene filling pipelines. The construction of filling pipelines is a new process with high technical content, and there are few relevant construction specifications, plans, and technical summaries. , and the medium in the pipe is acetylene, which belongs to Class A combustible gas, which is flammable and explosive. The construction quality of the filling pipe directly affects the safe production of the system. The existing acetylene filling pipe construction technology is prone to explosion, and the sub-pipes will be staggered and deformed. In the past, the small pipe filling method was used, and the worklo...

AI Technical Summary

Problems solved by technology

The existing acetylene filling pipe construction technology is prone to explosion, and the sub-pipes will be staggered and deformed. In the past, the small pipe filling method was used, and the workload was relatively large. Therefore, a high-pressure stainless steel acetylene filling pipe construction process was designed.
