为便于本领域技术人员理解本发明技术方案，现结合具体实施例对本发明技术方案做进一步的说明。
本发明技术方案一种耐腐蚀抗高温高压管道，包括管道本体以及分别涂覆在管道本体内表面和外表面上的内防腐涂层和外防腐涂层，外防腐涂层外部包覆有外保温层，外保温层外部设置有外防护层。内防腐涂层和外防腐涂层分别实现管道本体内表面和外表面的防腐、防锈，避免管道腐蚀，延长管道使用寿命，降低管道使用和维护维修成本。
现有技术中，管道防腐主要着重于外表面，对输送的介质对管道内壁的腐蚀忽视，这样一方面降低了管道的防腐能力，另一方面还使得管道内壁被腐蚀后部分物质进入被输送的介质中，影响被输送的介质品质。本技术方案中提出的内防腐涂层厚度不小于75um，主要由环氧粉末和纳米碳纤维制成，其中环氧粉末100～150份，纳米炭纤维10～20份。纳米碳纤维就能够有效提高内防腐涂层的光滑度，提高内防腐涂层的附着能力，使得内防腐涂层具有一定的对抗管道本体自身晃动或变形的能力，在管道本体微小的晃动或变形中，内防腐涂层不会发生断裂，提高内防腐层的防腐能力。内防腐涂层还包括以下质量分数的组分：润滑剂1～6份和交联剂0.1～2份，其中，润滑剂为聚乙烯蜡，交联剂为硅烷。润滑剂和交联剂的添加提高内防腐层的化学特性。
由于管道长期深埋于地下，外防腐涂层必不可少。本技术方案中的外防腐涂层厚度不小于80um。主要由环氧粉末和聚四氟乙烯制成，其中环氧粉末100～150份，聚四氟乙烯20～60份。聚四氟乙烯的使用使得外防腐涂层具有良好的耐腐蚀性、密封性、电绝缘性和良好的抗老化耐力。外防腐涂层还包括以下质量分数的组分：纳米炭纤维10～20份、润滑剂1～6份和交联剂0.1～2份，其中润滑剂为聚乙烯蜡，交联剂为硅烷。
在外防腐涂层外部包裹外保温层，外保温层厚度不小于35mm。主要由热塑性树脂制成和碳素纤维复合材料制成，热塑性树脂300～450份，碳素纤维复合材料30～100份；热塑性树脂为高密度聚乙烯、聚丙烯、聚氯乙烯、聚苯乙烯以及聚四氟乙烯中的一种或多种混合物。外保温层具有耐高温高压，耐低温、耐酸碱腐蚀、抗氧化等能力，使用寿命长，可用于介质长距离输送，减少介质能力损失，降低管道对周围环境的影响，避免不必要伤害。
在外保温层外设置外防护层，用于对保温层进行固定和保护。外防护层厚度不小于1.5mm，主要由高密度聚乙烯和聚丙烯制成，其中高密度聚乙烯100～200份，聚丙烯50～120份。外防护层还包括以下质量分数的组分：环氧树脂20～30份、聚氯乙烯糊树脂10～40份、聚氨酯泡沫塑料10～30份、聚四氟乙烯10～20份、环氧稀释剂3～10份、水性硅酮树脂1～10份、纳米胶粉1～10份、乙酸异丙酯1～10份、石墨1～10份和促进剂1～10份。外防护层用于隔离外部环境与外保温层，实现对外保温层进行保护，避免外保温层出现破坏，间接的避免管道本体出现损坏的问题。通过设置外防护层，实现对管道本体和外保温层进行保护，避免因周围环境的微小变化对管道造成局部外界压力，避免管道变形等，提高管道本体对抗环境结构变化的能力。
本发明技术方案中还提出一种耐腐蚀抗高温高压管道的制作方法。耐腐蚀抗高温高压管道按照以下步骤制备：
第一步，制备内防腐涂层和外防腐涂层，将内防腐涂层和外防腐涂层分别按照配方配比制备内防腐涂层混合涂料和外防腐涂层混合涂料，然后通过喷涂设备将内防腐涂层混合涂料和外防腐涂层混合涂料分别喷涂在管道本体内壁和外壁上；均匀喷涂且至少喷涂两层，内防腐涂层总厚度不小于75um，外防腐涂层总厚度不小于80um。
第二步，成型外防护层，首先按照外防护层原料配方配比准备外防护层制备的原料，通过成型机成型外防护层，冷却成型，获得外防护层。
第三步，成型外保温层；首先按照外保温层配方配比准备外保温层的原料，然后热塑性树脂和碳素纤维复合材料均匀混合；然后将第二步中成型的外防护层套设在已经成型内防腐涂层和外防腐涂层的管道本体外部，且两端封堵，并相对固定；再后将热塑性树脂和碳素纤维复合材料混合物填充在管道本体与外防护层之间；最后向管道本体与外防护层之间充入高温蒸汽，热塑性树脂和碳素纤维复合材料混合物发泡成型，制得外保温层。
上述制作步骤中，制造过程简单快速，防腐能力好，管道本体具有一定的对抗环境变化的能力。
上述技术方案中，先成型外防护层，后在外防护层与管道本体之间直接成型外保温层，外保温层成型快速，成型效果好，使得外保温层与管道本体外壁之间无间隙，保温隔热效果好。
本发明技术方案在上面结合实施例对发明进行了示例性描述，显然本发明具体实现并不受上述方式的限制，只要采用了本发明的方法构思和技术方案进行的各种非实质性改进，或未经改进将发明的构思和技术方案直接应用于其它场合的，均在本发明的保护范围之内。
