Whitehouse对接焊管生产工艺漂洋过海并在欧洲和北美大陆生根,其应用范围之广开创了对接焊管的黄金时代。在欧洲,对接焊管的黄金时代持续了大约60年,直到1905年无缝钢管(Mannesmanns法)与之形成激烈竞争。在美国,对接焊管的使用持续了90年,最终约在1930年被Fretz-moon连续生产
Whitehouse butt pipe production process across the sea and root in Europe and North America, its wide range of applications to open a golden era of butt welded pipe. In Europe, the golden age of butt-welded pipes lasted for about 60 years until the Mannesmanns method became a fierce competition in 1905. In the United States, the use of butt-welded pipes lasted for 90 years, culminating in a continuous production by Fretz-moon in about 1930
