我国现今的埋地输送钢管,无论是油气管还是水管,都将对接焊接看成是当然的、甚至是唯一可行的连接;水管有输送量大、工作压力相对低的特性,对接焊接已不是最优选择,它有自己的个性连接;国外发达国家已开发并应用着更经济、更方便可靠的柔性胶圈连接及承插搭接焊连接;掌握多种连接技术并给以实施,是中国输水钢管发展的必由之路。 China's current buried pipe delivery, both oil and gas pipe or water pipes, will be butt soldering as a matter of course, and even the only viable connection; water pipe has a large capacity, relatively low pressure characteristics, butt welding is not the most It is preferable to choose, it has its own personality connection; developed countries have developed and applied more economical, more convenient and reliable flexible apron connection and socket lap welding connections; master a variety of connection technology and to give effect to China's transport Water pipe development of the only way.
