双金属复合管由两种不同金属材料构成,以碳素钢管或合金钢管为基管,在其内表面覆衬一定厚度的不锈钢、镍基合金等耐蚀合金的复合管,管层之间通过各种变形和连接技术形成紧密结合,从而使两种材料结合成一体,制成一种新型金属复合管材。 Double metal composite pipe made of two kinds of metal materials, carbon steel or alloy tube with steel pipe, composite pipe, stainless steel and nickel based alloy corrosion resistant alloy on its inner surface covered with a certain thickness of the layer between the tube through a variety of deformation and connection technology closely integrated, combined with the two kinds of materials one, made of a new type of metal composite pipe. 其一般设计原则是基材满足管道设计许用应力,复层耐腐蚀或磨损等。双金属复合管兼有基层和复层的所有优点,相对于整体合金管能有效降低成本,针对整体合金管具有应力腐蚀开裂敏感性的氯化物或酸性环境,复合管可以提高安全性和可靠性,在石油、化工、核电、轻工和机械工程等行业有着广阔的应用前景。 The general design principle is that the base material satisfies the allowable stress of the pipe design, the corrosion resistance or wear of the compound layer. All the advantages of double metal composite pipe has the base layer and clad layer, compared to the overall alloy tube can effectively reduce the cost for the overall alloy tube with stress corrosion cracking of chloride or acid environment, composite pipe can improve the safety and reliability, has a broad application prospect in the petroleum, chemical, nuclear power, light industry and mechanical engineering etc.. 复合管产品按使用性质可分为化工用液体气体用管、石油天然气输送管及油井复合管、锅炉用复合管、废物焚烧炉用复合管、热交换器用复合管、耐磨损用复合管、耐腐蚀结构用复合管以及建筑装潢用复合管等。 According to the nature of the use of composite pipe products can be divided into chemical liquid gas pipes, oil and gas and oil conveying pipe composite pipe, composite pipe, boiler waste incinerator with composite pipe, composite pipe, heat exchanger with wear-resistant composite pipe, corrosion resistant structure with composite pipe, composite pipe and other building decoration. 石油天然气输送管及油井复合钢管通常选用耐腐蚀材料如不锈钢、Incoloy625、Incoloy825等镍基合金作为内层管,以保证该管道的耐腐蚀性能。而外层材料通常为X42、X50、X60、X70、ASTM-A106GB、A335-P22等材料,以保证该管道的强度。由这两类材料组合成的复合钢管亦适用于开发地热用的取水管道。 Petroleum and natural gas transmission pipes and oil well composite steel pipes usually use corrosion resistant materials, such as stainless steel, Incoloy625, Incoloy825 and other nickel based alloys as inner tubes to ensure the corrosion resistance of the pipeline. And the outer material is usually X42, X50, X60, X70, ASTM-A106GB, A335-P22 and other materials to ensure the strength of the pipe. The composite steel pipes composed of these two kinds of materials are also suitable for the development of water intake pipes for geothermal use. |
