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。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。 The general design principle is that the base material meets the design allowable stress of the pipeline, and the coating is corrosion-resistant or wear-resistant. Bimetallic composite pipe has all the advantages of base and cladding. Compared with integral alloy pipe, it can effectively reduce the cost. Aiming at chloride or acid environment with stress corrosion cracking sensitivity of integral alloy pipe, the composite pipe can improve the safety and reliability. It has a broad application prospect in petroleum, chemical industry, nuclear power, light industry, mechanical engineering and other industries. Composite pipe products can be divided into chemical liquid gas pipe, oil and natural gas transmission pipe and oil well composite pipe, boiler composite pipe, waste incinerator composite pipe, heat exchanger composite pipe, wear-resistant composite pipe, corrosion-resistant structure composite pipe and building decoration composite pipe according to their use properties. |
