本文以瓮福磷矿区中低品位磷矿综合利用项目----精矿输送主线管道工程为例,简要介绍了管道焊接质量的重要性。现代工业设施介质普遍用管道输送,管道具有多种用途,被广泛用于化工生产、电力工业、矿山等行业,生产效率显著提高,具有深远的意义,其中长距离输送管道尤为明显。由于长距离输送管道承受高压及介质冲刷,受到焊接应力的影响,薄弱环节的焊缝特别容易损坏,对安全生产的威胁显而易见。
In this paper, Wengfu phosphate mine in low-grade phosphate rock comprehensive utilization project - concentrate delivery pipeline project as an example, briefly introduced the importance of pipe welding quality. Modern industrial media commonly used pipelines pipeline, pipeline has a variety of uses, is widely used in chemical production, power industry, mining and other industries, production efficiency significantly improved, with far-reaching significance, including long-distance pipeline is particularly evident. Due to the long-distance pipeline under high pressure and medium erosion, by the impact of welding stress, the weld of weak links are particularly vulnerable to damage, the threat to the safety of production is obvious.
