產(chǎn)品說明:

概述:
    陶瓷內(nèi)襯復(fù)合鋼管是國家高科技術(shù)“八六三”計(jì)劃中研制成功并率先產(chǎn)業(yè)化的具有國際先進(jìn)水平的復(fù)合新材料,。該管從內(nèi)到外分別由陶瓷,、過渡層和鋼三層組成。陶瓷層是在2000度以上高溫形成的致密的鋼玉瓷通過過渡層同鋼管形成牢固的冶金結(jié)合,,具有良好的耐蝕,、耐磨、耐高溫及高強(qiáng)度,、高韌性,,高抗機(jī)械沖擊和抗熱沖擊的綜合性能,且能進(jìn)行車削,,磨削和焊接等加工,。

Overview:
    Ceramic-lined composite steel pipe is the national high-tech "eight six three" plan in the successful development and the first industrialization of the international advanced level of composite materials. The tube from the inside out, respectively, by the ceramic, transition layer and steel composed of three. Ceramic layer is formed at a high temperature of more than 2000 degrees of dense steel jade porcelain through the transition layer with the pipe to form a solid metallurgical combination, with good corrosion resistance, wear resistance, high temperature and high strength, high toughness, high resistance to mechanical shock and resistance Thermal shock of the overall performance, and can be turning, grinding and welding and other processing.
