1、石油天然气输送管及油井 1. Oil and gas pipelines and wells. 常选用耐腐蚀的不锈钢、Incoloy625、Incoloy825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、A335-P22等材料以保证该管道的强度。 Corrosion resistant stainless steel, Incoloy 625 and Incoloy 825 are often used as inner pipes to ensure the corrosion resistance of the pipes. The outer materials are usually X42, X50, X60, X70, A335-P22 and other materials to ensure the strength of the pipeline. 日本、美国等国对有关复合钢管用作天然气输送管道进行过大量研究,美国石油协会(API)制订出管线用复合钢管的标准,编号为API5LD。API的主要品种有CrMo钢与超级13Cr、G3、C028等复合的油井管;825、028等镍基合金钢的复合管。 Japan, the United States and other countries have done a lot of research on the use of composite steel pipes as natural gas pipelines. The American Petroleum Association (API) has formulated a standard for composite steel pipes for pipelines, which is API5LD. The main varieties of API are CrMo steel and super 13Cr, G3, C028 and other composite well pipe; 825, 028 and other nickel-based alloy steel composite pipe. 2、锅炉 2. Boiler 锅炉过热器的钢管应具有耐650 ℃、35 MPa蒸汽条件下的高温强度,优良的外表面耐高温腐蚀能力和内表面耐水蒸汽氧化性能等特性。 The steel tube of boiler superheater should have high temperature strength under 650 C and 35 MPa steam condition, excellent corrosion resistance on outer surface and steam oxidation resistance on inner surface. 日本住友金属公司用SUS310S、35Cr-55Ni、40Cr-55Ni材料作外层基管,用17-14CuMo和Alloy800H等材料作内层管,开发出超超临界锅炉过热器用新型复合钢管。 Sumitomo Metal Corporation of Japan has developed a new type of composite steel tube for superheater of ultra-supercritical boiler with SUS310S, 35Cr-55Ni, 40Cr-55Ni as outer base tube and 17-14CuMo and Aloy800H as inner tube. 瑞典Sandvik钢铁公司成功开发出由碳钢作内层,耐蚀性好的Sanicro28钢作外层管,制作的复合钢管在锅炉结构设计上无需任何变更,可直接使用。 Sandvik Steel Company of Sweden has successfully developed Sanicro28 steel tube with carbon steel as inner layer and good corrosion resistance as outer layer. The composite steel tube can be used directly without any change in boiler structure design. 3、废物焚烧炉 3. Waste incinerator 废物焚化炉选用复合钢管,其外层基管可选用Sanicro65合金,而内层材料可选用具有耐应力腐蚀裂纹的碳钢或铬钼钢。 Composite steel pipe is used in waste incinerator, Sanicro65 alloy is used in outer base pipe and carbon steel or chromium-molybdenum steel with stress corrosion crack resistance in Inner material. 欧洲、美国等自1971年安装第一台复合管焚烧炉过热器和水冷壁用管以来,已使用了200万米复合钢管。 Since 1971, when the first composite tube incinerator superheater and water wall tubes were installed in Europe and the United States, 2 million meters of composite steel tubes have been used. 4、热交换器 4. Heat exchanger 作为热交换器用复合钢管,除应具有一定的强度和耐蚀性外,还应有较好的导热性。 As a composite pipe for heat exchanger, it should not only have certain strength and corrosion resistance, but also have better thermal conductivity. 瑞典Sandvik钢铁公司选用高合金镍铬钢合金800作内管,以低合金钢ASTMA213Ti2作外管,生产复合钢管。 Sandvik Steel Co., Ltd. Sweden selected high alloy nickel-chromium steel alloy 800 as the inner tube and low alloy steel ASTMA213Ti2 as the outer tube to produce composite steel tube. 日本NKK公司选用API5L-16MnV钢作外层,选用NIC42钢作内层制成复合钢管,其力学性能达到API5L-16MnV技术要求,界面结合剪切强度达到400 MPa以上。 NKK Corporation of Japan selects API5L-16MnV steel as outer layer and NIC42 steel as inner layer to make composite steel pipe. Its mechanical properties meet the technical requirements of API5L-16MnV and the interfacial bonding shear strength reaches more than 400 MPa. 5、耐磨损领域 5. Wear resistance area 日本山阳特殊钢公司用SUS316L耐蚀钢作外层,用司太立No12耐磨合金作内层,制成复合钢管,使用4年仍然如新。这种复合钢管在其他微粉颗粒的气力输送管道上也得到了很好的应用,其需求量正在逐新增加。 The composite steel pipe made of SUS316L corrosion-resistant steel as outer layer and Stelli No12 wear-resistant alloy as inner layer is still as new in use for 4 years. This kind of composite steel pipe has been well used in other pneumatic conveying pipes with fine powder particles, and its demand is increasing. 6、海水管道 6. Seawater pipeline 选用镍、钛不锈钢或铜合金作内层,以碳钢或低合金耐蚀钢作外层基管组成的复合钢管。 Nickel, titanium stainless steel or copper alloy are used as inner layer and carbon steel or low alloy corrosion resistant steel as outer base tube. 日本川崎制钢和日本钢管公司生产的海水管道用复合钢管广泛用作海水热交换器川管和海水淡化装置的取水管道。 Composite steel pipes for seawater pipelines produced by Kawasaki Steel and Japan Steel Tube Company are widely used as water intake pipes for seawater heat exchangers and seawater desalination units. 双金属复合管在国内油气工业的石油产品输送、炼化行业应用逐渐推广,但国内在复合工艺、高效生产和检测技术方面与国外相比仍有较大差距,应该说这是钢管领域的一个新兴热点产业,值得持续关注和后期转入。 The application of bimetal composite pipe in petroleum product transportation and refining industry of domestic oil and gas industry is gradually popularized, but there is still a big gap between domestic and foreign in composite process, efficient production and testing technology. It should be said that bimetal composite pipe is a new hot industry in the field of steel pipe, which deserves continuous attention and later transfer. |
