技术领域technical field
本发明属于液溴储运装置的制造技术领域，具体涉及20英尺液溴罐式集装箱罐内部管道的制造方法。The invention belongs to the technical field of manufacturing liquid bromine storage and transportation devices, and in particular relates to a method for manufacturing an internal pipeline of a 20-foot liquid bromine tank type container tank.
背景技术Background technique
溴是盐化工的一种重要的产品，溴的用途非常广泛，是制造各种溴盐和有机溴化物的基本化工原料，广泛用于石油工业、化学工业和制药工业，是燃料抗爆剂、阻燃剂，灭火剂、染料中间体、感光材料、杀虫剂、制冷剂等产品的主要原材料。Bromine is an important product of salt chemical industry. Bromine has a wide range of uses. It is the basic chemical raw material for the manufacture of various bromine salts and organic bromides. It is widely used in the petroleum industry, chemical industry and pharmaceutical industry. It is a fuel antiknock agent, Flame retardants, fire extinguishing agents, dye intermediates, photosensitive materials, insecticides, refrigerants and other products are the main raw materials.
溴是液体单质，一种双原子分子，分子式Br2，分子量159.81。溴是剧毒和强腐蚀性液体。溴的比重为3.12g/cm3，比水重，是水的3.12倍，溴的溶点是-7.25℃，沸点是58.78℃。Bromine is a liquid element, a diatomic molecule with a molecular formula of Br2 and a molecular weight of 159.81. Bromine is a highly toxic and highly corrosive liquid. The specific gravity of bromine is 3.12g/cm 3 , which is 3.12 times heavier than water. The melting point of bromine is -7.25°C and the boiling point is 58.78°C.
溴的化学性质非常活泼，除银、铅、铂、钽外极易与其他金属反应，同时放出大量的热量。溴对玻璃、陶瓷、聚四氟乙烯塑料、辉绿岩、花岗岩等材料腐蚀作用小。The chemical properties of bromine are very active, and it is very easy to react with other metals except silver, lead, platinum, and tantalum, and release a lot of heat at the same time. Bromine has little corrosive effect on glass, ceramics, PTFE plastics, diabase, granite and other materials.
一般小包装溴的储存运输采用陶瓷坛，每坛净重25kg或30kg，瓷坛装入木箱后，进行包装和运输。Generally, ceramic altars are used for storage and transportation of bromine in small packages. The net weight of each altar is 25kg or 30kg. After the porcelain altars are packed into wooden boxes, they are packaged and transported.
大包装运输采用衬铅罐式集装箱，其构造为集装箱框架内在罐体鞍座上安装一个内表面衬铅的钢制罐体。所有阀门和罐内管路都安装在罐顶的阀门安装法兰上，并用阀门箱进行封闭。Lead-lined tank containers are used for bulk transportation, which is constructed by installing a lead-lined steel tank on the tank saddle within the container frame. All valves and pipelines in the tank are installed on the valve mounting flange on the top of the tank and closed with a valve box.
进液管、出液管、压缩氮气等罐内管路可用内外覆盖金属铅层钢管进行制造。保证罐式集装箱进行灌装液溴和卸出液溴。The pipelines in the tank, such as liquid inlet pipe, liquid outlet pipe, and compressed nitrogen gas, can be made of steel pipes covered with metal lead layers inside and outside. Ensure that tank containers are filled with liquid bromine and unloaded with liquid bromine.
由于内外覆盖金属铅层钢管市场上并无供应，因此需自行加工。Since there is no supply on the market for steel pipes covered with metal lead layers inside and outside, it needs to be processed by itself.
通常钢管内壁覆盖金属铅层的加工方法是将薄壁铅管装入套在钢管内壁中。Usually the processing method that the inner wall of the steel pipe is covered with the metal lead layer is to pack the thin-walled lead pipe into the inner wall of the steel pipe.
由于钢管和铅管在材料供应和套管装配方面的问题，铅管和钢管之间存在较大的间隙。这会使铅金属层无法紧密和钢管贴合，形成脱空，在使用时由于铅层在运输过程中的振动和本身重力作用下造成下坠，容易使铅层开裂失去防护液溴的功能，从而造成管子失效。There is a large gap between the lead pipe and the steel pipe due to the problems in material supply and casing assembly of the steel pipe and the lead pipe. This will make the lead metal layer unable to fit tightly with the steel pipe, resulting in voids. During use, the lead layer will fall under the action of vibration during transportation and its own gravity, which will easily cause the lead layer to crack and lose the function of protective liquid bromine, thus cause the tube to fail.
由于铅管较薄同时铅的强度很低，因此铅管在钢管内很难保证管状外形以保证流体正常流动。Because the lead pipe is thin and the strength of lead is very low, it is difficult to ensure the tubular shape of the lead pipe in the steel pipe to ensure the normal flow of fluid.
发明内容Contents of the invention
本发明主要解决的技术问题是提供一种液溴集装箱罐体的钢管内壁覆盖金属铅层的加工方法。The technical problem mainly solved by the invention is to provide a processing method for covering the inner wall of a steel pipe of a liquid bromine container tank with a metal lead layer.
该方法可以使钢管内壁的金属铅层和钢管之间紧密贴合，以防止在使用时钢管内壁所覆盖金属铅层在运输过程中的振动和本身重力作用下造成铅层开裂，避免因钢管失去防护液溴腐蚀的功能造成管子失效。This method can make the metal lead layer on the inner wall of the steel pipe closely adhere to the steel pipe, so as to prevent the metal lead layer covered by the inner wall of the steel pipe from cracking due to vibration during transportation and the action of its own gravity during use, and to avoid loss of the lead layer caused by the steel pipe. The function of the bromine corrosion protection fluid caused the pipe to fail.
该方法可以避免因为铅管较薄同时铅的强度很低，而造成铅管在钢管内变形影响流体正常流动。The method can avoid that the deformation of the lead pipe in the steel pipe affects the normal flow of the fluid due to the thin lead pipe and the low strength of the lead.
为解决上述问题，本发明采用将穿入钢管内的铅管中用液体打压的方法使铅管涨形并紧密贴合在钢管内壁上(图1)，在钢管内壁形成紧密贴合的金属铅覆盖层。In order to solve the above problems, the present invention adopts the method of pressing the lead pipe penetrated into the steel pipe with liquid to make the lead pipe expand and fit closely on the inner wall of the steel pipe (Fig. overlay.
其特征在于其步骤为：It is characterized in that its steps are:
1)在钢管内部穿入所需贴合的铅管。1) Penetrate the required fitting lead pipe inside the steel pipe.
2)在钢管两端头部将密封头装入铅管并保证密封，同时将密封头卡在钢管端部防止打压时跑出。2) Put the sealing head into the lead pipe at both ends of the steel pipe to ensure the seal, and at the same time, clamp the sealing head at the end of the steel pipe to prevent it from running out when it is pressed.
3)在两端密封头上接排气阀、加压阀、进出液阀，并接入进出液管路和加压管路(图1)。3) Connect the exhaust valve, pressurization valve, liquid inlet and outlet valves to the sealing heads at both ends, and connect the inlet and outlet pipelines and pressurization pipelines (Figure 1).
4)打开进出液阀和排气阀使加压液体充满铅管内部，并排除铅管内气体。4) Open the liquid inlet and outlet valves and exhaust valves to fill the lead pipe with pressurized liquid and remove the gas in the lead pipe.
5)关闭进出液阀和排气阀，打开加压阀。使铅管内液体压力缓慢升高到所需要的压力值。保压一定时间后卸除压力。5) Close the inlet and outlet valves and exhaust valves, and open the pressurization valve. Slowly increase the liquid pressure in the lead pipe to the required pressure value. After holding the pressure for a certain period of time, the pressure is released.
6)打开进出液阀和排气阀卸除管内液体，拆除两端密封头及所连接的阀门和管路。切除两端密封头处涨形不到位的管路。6) Open the inlet and outlet valves and exhaust valves to remove the liquid in the pipe, and remove the sealing heads at both ends and the connected valves and pipelines. Cut off the pipes that are not in place at the sealing heads at both ends.
采用这种方法后，可以使钢管内壁的铅管和钢管之间紧密贴合，以防止在使用时钢管内壁所覆盖金属铅层在运输过程中的振动和本身重力作用下造成铅层开裂，避免因钢管失去防护液溴腐蚀的功能造成管子失效，同时避免铅管在钢管内变形影响流体正常流动。After adopting this method, the lead pipe on the inner wall of the steel pipe can be closely bonded to the steel pipe, so as to prevent the metal lead layer covered by the inner wall of the steel pipe from cracking under the vibration of the inner wall of the steel pipe during transportation and the action of its own gravity. Because the steel pipe loses the function of protecting the bromine corrosion of the liquid, the pipe fails, and at the same time, the deformation of the lead pipe in the steel pipe is prevented from affecting the normal flow of the fluid.
