一种超高分子量聚乙烯增强大流量输送高压软管及其制造方法 技术领域
本发明涉及一种高压软管及其制造方法，具体涉及一种超高分子量聚乙烯增强大流量输送高压软管及其制造方法。
背景技术
软管因易弯曲、能缓冲、重量轻及安装使用方便等优点，用途十分广泛，如用于矿井液压支架、油田开发、工程建筑、起重运输、冶金锻压、矿山设备、船舶、注塑机械、农业机械、各种机床以及各工业部门机械化、自动化液压系统中输送具有一定压力和温度的石油基(如矿物油、可溶性油、液压油、燃油、润滑油)及水基液体(如乳化液、油水乳浊液、水)等和液体传动的管路。超高分子量聚乙烯增强大流量输送高压软管，是继轮胎、输送带之后的第三大高分子材料工业技术领域，由于其具有质量轻、包装体积小、操作方便、环境适应性强等特点，可替代胶管、钢管等用于石油产品、化学液体、水等液体的正压输送，用于井台从井下向地面上水、近海石油及泥浆等输送、农田灌溉、城市消防等，更可作为输油(水)管线用于军事后勤领域。在美、英、法、俄、澳等国的军队中，这种可扁平软管已成为军事后勤液体输送的主要装备，此类软管具有广阔的应用前景。
随着能源的缺乏，开发近海和浅海油田，页岩气勘探已作为新能源战略，提上了议事日程。一口典型的页岩气水平钻井，在钻探过程中需要使用4000～15000m3压裂液，其中水含量占90％。传统的金属管道，由于不易弯曲、安装、使用、维护成本高等诸多弊端，已不能适应页岩油气勘探的要求，尽快解决高分子复合软管生产和研制与国外的差距，赶上发达国家的水平，有利于节约资源，保护环境，符合我国产业发展的方向。为了提高效率，大口径远程高压输送已经成为必然。消防上大型救火已经开始用大口径软管输水，石油和页岩气，天然气的开采等已经在寻求方案，野外或者海上长距离用常用金属管道，此种方法的缺点是铺设工作量大，铺设比较困难，更主要的是在管道连接处易产生裂缝导致水的渗漏造成污染。普通大口径软管由于工作压力受增强层材质的制约受到限制， 长输送效率低。针对种情况有的公司采用纺轮做增强层生产大口径软管来解决目前的问题，这种软管可以提高工作压力做成高压软管，但该产品缺点是纺轮耐弯曲性能差，对工作压力损伤大，使用寿命低。现在中国市场上大口径软管最大口径也只能做到300，大口径橡胶软管一次成型的产品在中国还是空白。
