| 首先，相同的是，两种都是“双金属”复合，原理上都是外层基管与内衬管材的复合，保留两种不同材料内在的优点，互补不足。满足同一铸件不同部件有截然不同的性能的要求，以及为了节约贵合金和降低成本而采用双金属复合。不锈钢双金属复合管结构示意图，外层为基管，内层为不锈钢衬管，外层承压，内层防腐蚀。工艺主要有机械机械滚压法、爆炸复合法、拉拔复合法、液压复合法，原理是通过加压弹性收缩紧密嵌合。主要用于水务、给水管材、石油天然气输送管线，电力除盐水、脱硫管线等。 First of all, the same is that both are bimetallic composite, in principle, both are composite of outer base pipe and inner lining pipe, retaining the inherent advantages of the two different materials, and lack of complementarity. To meet the requirements of different parts of the same casting with different properties, and to save precious alloy and reduce cost, bimetal composite is used. Structural diagram of stainless steel bimetal composite pipe, the outer layer is base pipe, the inner layer is stainless steel liner, the outer layer is pressure bearing, and the inner layer is anti-corrosion. The technology mainly includes mechanical rolling, explosion compounding, drawing compounding and hydraulic compounding, and the principle is to close the inlay by compression elastic contraction. It is mainly used in water service, water supply pipe, oil and gas transmission pipeline, electric desalted water, desulfurization pipeline, etc. 浇铸出来的半成品——内衬管为高铬合金 Cast semi-finished product: the inner liner is made of high chromium alloy 而高铬双金属复合管，外层为Q235钢管，内衬层为高铬合金。工艺主要有离心成型工艺法、消失模铸造法。原理是把两种成分不同、性能各异的金属熔铸或镶铸在一起，中间层为冶金结合。主要用于火电厂、洗煤厂、矿山输送管线等。 The outer layer of high chromium bimetal composite pipe is Q235 steel pipe and the inner layer is high chromium alloy. The main processes are centrifugal molding and EPC. The principle is to melt or cast two kinds of metals with different compositions and properties together, and the middle layer is metallurgical combination. It is mainly used in thermal power plant, coal washing plant, mine transmission pipeline, etc. |
