花格输油管道不停输大修的安全保证

对花格输油管道不停输大修的强度安全保证作了介绍，既在不影响油田开发和炼厂生产、减少漏油损失、降低污染、节省投资的条件下，通过制定科学的施工方案 ，在试验的基础上以强度安全保证为核心进行施工设计，合理选用材料；科学制作补板，更新防腐结构，严格按照安全管理规范进行施工，首次实现了国内管道不停输大修。积累的安全施工经验，为陆上长距离输油管道不停输大修提供了有益的借鉴。

In-line Overhaul Practice in Huatugou-Golmud Oil Pipeline

An in-line overhaul program for Huatugou-Golmud oil pipeline is put forward due to serious corrosion in the pipeline in recent years. The in-line overhaul principle is to decrease leakage loss,eliminate environment pollution and save cost. The in-line overhaul program has been successfully implemented and helpful results have been obtained. In the paper,the site test and in-line overhaul process are introduced.
