Abstract: Elaborated in the essay are the activities as carried out in America to build pipeline systems with ERW and HFW pipes, including collecting the historic data concerning failures of weld seams of such welded pipes, analyzing the effectiveness of interior checking of the piping, the hydrostatic testing and the forecasting model, conducting quantitative experiment research on the resistance of the weld of the pressure-bearing steel pipe, and carrying out research on gully corrosion, etc.The results of the above mentioned research activities are comprehensively analyzed.Accordingly suggestions are made for using HFW pipes for domestic pipeline system construction.It is suggested that great care has to be taken to select types of the HFW pipe when designing the pipeline system, and that although the HFW pipe in general has no problem for construction of oil and gas pipeline systems, it is critical to choose HFW makers with high technical level and relatively reliable and complete QA management system for pipeline construction projects.Moreover it is also suggested that based on specific characteristics of the project, relevant strict purchase technical specifications for the HFW pipe be prepared so as to assure the quality level of the pipeline system.
