ＩＨＵ钢管系指采用内高压变形的大口径薄壁管。Ｈｏｏｇｏｖｅｎｓ和Ｓｏｕｎｄｒｏｎｉｃ公司已签约决定合作研制一种生产这类钢管和铝管的设备。该产品主要用于汽车工业的车体部件,由于直径/壁厚比特别大,故难以生产。首批ＩＨＵ坯管于1999年9月交付使用。荷兰Hoogovens和So
IHU steel pipe refers to the use of high pressure deformation of large-diameter thin-walled tubes. Hoogovens and Soundronic have signed a contract to work together to develop a device for the production of such pipes and tubes. The product is mainly used in the automobile industry body parts, due to the diameter / wall thickness ratio is particularly large, it is difficult to produce. The first batch of IHU billets was delivered in September 1999. Netherlands Hoogovens and So
