摘要
Abstract
Along the pipeline engineering of refined oil transportation produced by Ningxia Petrochemical Corporation,there are many cultivated lands,in order to reduce the cost,the pipeline engineering should be constructed in winter when the temperature is low and there are no cash crops.Welding in winter construction mainly takes measures such as preheating,windbreak shelter,keeping interpass temperature and post welding heat treatment, flap closure and so on, to ensure the welding quality .When the measures accounted above are used in the welding of L245 pipeline steel,the radiographic inspection test and mechanical properties of weld joint one-time qualified quality reaches 99.64%,which can satisfy the quality standards.Moreover,after the quality assurance measures are taken in the winter construction, the quality of the weld has been improved, the cost has been reduced and following great economic and social benefits.关键词
