文档介绍：摘要
铁路、公路、航空、水运与管道运输统称为五大运输业。管道运输是最为经济、简单的一种运输方式,特别是对于石油、成品油、天然气、矿浆和水等流体来说更为有效,其特点是经济、安全和不间断输送。由于管线运输具有运量大、距离长、成本低和安全性高等优点,因而在国际上得到迅速的发展。
X80管线钢管道是目前世界管道中真正进入工程建设用的最高钢级管道,本文首先全面分析了国内外油气管道及X80管线钢管道的发展、应用和焊接技术状况。然后对X80级管线钢进行了焊接性分析,研究了X80管线钢管道现场焊接的工艺方案。针对X80管线钢管道环焊缝焊接,吸收和借鉴国内外先进的工艺设计理念,提出了一套自己的X80管线钢管道环焊缝焊接工艺设计思路,包括焊接设备选取、焊材选择、坡口加工、工装应用和焊接工艺参数的确定等一系列工作。这一系列工作是在已有生产实际的基础之上,加以改进的。

ABSTRACT
Railway, highway, aviation, water and pipeline transport referred to as five most economical, pipeline transport is a simple mode of transportation, especially for the oil, gas, oil, water and pulp is more effective, and its features are economic, security and continuous to the large volume has pipelines, long distance, low cost and high security, resulting in the development of international rapidly.
X80 pipe steel pipe in the world is now truly into construction with the highest level of steel pipe, this prehensively analyzed the gas pipeline and the development of pipeline steel X80 and welding technology and application situation. Then to X80 pipe steel grade weldability analysis, research the steel welding X80 pipe road scene of technological scheme. According to X80 pipe welding welding steel ring and assimilate and advanced process design concept, puts forward a set of their X80 pipe welds welded steel ring process design, including welding equipment selection, welding material selection, processing, tooling application and welding parameters, etc. This series of works in the production practice is based on improved.
Key words: oil and gas pipeline;welding X80 pipe;welding method of steel welded;welding process.
