一种改性石油管路及其制备方法
技术领域
本发明属于运输设备制造技术领域，涉及一种钢管以及钢管的制造方法，特别是涉及一种改性石油管路及其制备方法。
背景技术
管道运输不仅运输量大、连续、迅速、经济、安全、可靠、平稳以及投资少、占地少、费用低，并可实现自动控制。除广泛用于石油、天然气的长距离运输外，还可运输矿石、煤炭、建材、化学品和粮食等。管道运输可省去水运或陆运的中转坏节，缩短运输周期，降低运输成本，提高运输效率。当前管道运输的发展趋势是：管道的口径不断增大，运输能力大幅度提高；管道的运距迅速增加；运输物资由石油、天然气、化工产品等流体逐渐扩展到煤炭、矿石等非流体。但由于现有多金属耐磨钢管在使用过程中因为钢管的不耐腐蚀导致多金属耐磨钢管从外表层开始破裂、损坏。
发明内容
本发明的目的是针对现有管道运输中钢管不耐腐蚀导致钢管从外表层开始破裂和损坏的不足，提出一种改性石油管路及其制备方法，能有效提高运输管道外表层的强度及硬度，可提高运输管道的抗腐蚀性能，能有效解决因外表层钢管的损坏而重新更换管道，有效的提高了管道的使用寿命，降低了维修成本。
本发明的技术方案是：一种改性石油管路及其制备方法，钢管层，所述钢管层外表面设有镀锌层，所述镀锌层外面涂覆有镀镁层，所述镀镁层外部浇注有薄铝层，所述钢管层内表面设有多金属层，所述钢管层、镀锌层、镀镁层、薄铝层和多金属层复合加工成整体式管状结构。
所述镀锌层的厚度为0.3mm。
所述多金属层的厚度为0.3mm。
所述镀镁层的厚度为0.2mm。
所述薄铝层的厚度为0.5mm。
一种改性石油管路及其制备方法，包括如下步骤：
(1)清除普通钢管内外铁锈及其杂物；
(2)混料，将如下比例多种金属粉均匀混合，取铜铅合金粉40%～50%、氧化铁粉15%～25%、氧化铜粉20～28%、纳米碳酸钙和纳米二氧化硅混合粉1%；其中铜铅合金粉铜铅比例为1:1，纳米碳酸钙和纳米二氧化硅混合比例为1:1；
(3)多金属层的复合加工，将钢管固定在模具上，使钢管匀速转动，其中钢管的转速在2000rpm速度转动；加入混合均匀的多种金属粉并点燃，使其均匀分布在钢管上；
(4)冷却，保持钢管匀速转动使预成型产品冷却至室温；冷却时转速为1000rpm速度转动；
(5)镀锌层的复合加工，将冷却的预成型产品摆放整齐，在外表面采用冷镀锌方式电镀一定厚度的镀锌层，使其表面光滑平整。
本发明的有益效果为：本发明提出的种改性石油管路及其制备方法，结构新颖，工作原理清晰，采用了钢管层、多金属层、镀锌层、镀镁层和薄铝层复合的整体结构，镀锌层的加入使多金属耐磨复合钢管的防腐蚀性能大大的提高，同时有效的提高了多金属耐磨管外表层钢管的强度及硬度。有效的解决了多金属耐磨管因为外表层钢管的损坏而重新更换管道。根据客户、现场的情况控制，纳米碳酸钙和纳米二氧化硅取代了以前的碳化硅，同时增加了纳米碳酸钙和纳米二氧化硅的含量有效的提高了多金属层的强度，韧性。降低铜铬合金粉、氧化铁粉含量，提高了氧化铝粉含量能明显降低多金属层的刚性。通过以上的调整能有效的降低多金属管因外腐蚀、多金属层因剧烈摩擦破坏而影响管道的使用寿命。能有效的降低管道的成本，提高产品的使用寿命。
