/><br>近年来，石化、燃气、自来水行业的管道建设速度突飞猛进，随着大量的建设和开工，管道管线运行的问题随之而来，管道管线预检、预修、巡视、检修和改造、消缺等。其中涉及到检修、改造管线的任务往往需要停输或停车，会造成很大的效益损失。带压开孔技术是采用机械切削方式在承压管道上加工出圆形孔的一种作业技术。这种技术在不需要管道停输、停车的情况下利用带压开孔机进行对管道或带压设备进行开孔，既不影响管线或设备的正常运行，又能安全、、环保的完成管线预留接口的目的。带压开孔技术是一种的设备或管道改造、抢修技术，它解决了相关设备或管线连续生产的难题，能带来的经济效益和社会效益。<br>利用带压开孔机对设备、管道进行带压开孔。在设备或管道带压焊接一个带法兰（或丝扣）阀门的短节，再把带压开孔机与法兰阀门连接，并打开阀门，然后把带压开孔刀具通过阀门接触到需要开孔的设备和管道上，再该短节、阀门、带压开孔机连接底盘所形成的空腔内，按被开孔管道的设计压力做好试压及气密测试工作，试压合格和经过审批后，转动刀具在相应的设备和管道上开孔，开孔成功后退出刀具和开孔带出的U型管壁，退出到阀门以外的带压开孔机底盘的空间内，然后关闭阀门，带压开孔机泄压并拆卸掉带压开孔机，带压开孔成功。<br>从开孔过程中可以看出，带压开孔主要利用短节、阀门、带压开孔机底座连接盘所形成的空腔来实现带压开孔作业的，其中的关键点为焊接短节时的焊接过程，属于带压焊接。根据焊接原理，焊接过程是一个熔化冶金过程，焊接中会形成一个局部的熔池，熔池温度很高，且会使周围金属温度升高，降低金属的抗拉强度。因此根据在焊接短节之前要测量被开管道的壁厚。<br>金明带压开孔技术适用于原油、成品油、化工介质、天然气等多种介质管线的正常维修改造和突发事故的抢修(如带压抢修、更换腐蚀管段、加装装置、分输改造等作业)。开孔时无需停产不影响产量和物料供给。<br

style="white-space:normal;">江苏雷鹏科技发展有限公司</span>是一家从事：天然气、石油、柴、蒸汽、水等管道开孔/带压堵漏/管道封堵/带压开孔/带压封堵/带压密封的企业。 <br /><br> 带压机械堵漏办法有哪些<br> 一、焊接办法的带压堵漏办法<br> 焊接带压堵漏是运用焊工进行焊接作业，对走漏点直接焊堵，然后构成关闭区，来完结带压堵漏。焊接堵漏作业有常压和带举动火焊接，该办法的特点是动火作业危险高，但堵漏效果好。<br> 二、粘接办法带压堵漏<br> 粘接堵漏是运用胶粘剂的特性来完结带压堵漏。技能简洁，除能粘接各种金属、非金属资料以外，还能粘接其他资料，这种办法既疾速又经济，已有些替代了传统的焊接、铆接和螺纹衔接等技能。在易燃易爆场合，更具有性。<br> 三、紧固式带压堵漏<br> 据从事山东带压堵漏方面的行业讲，为了消除因为螺栓和螺母法兰间的摩擦系数不均匀性致使的轴向力不均衡而进行的一项补正办法的带压堵漏办法。该堵漏办法的运用有必定针对性，它既是一种事前防止走漏的办法，也是一种堵漏办法。在防止走漏方面，主要是热紧固，它用在体系内部温度大于200℃的条件下，设备、管道等的密封组合部件因为技能作业需求，体系温度升高，各部件间就发生温差应力，致使各种密封件热膨胀不均匀，然后致使螺栓与螺母的热紧力不均衡，而也许致使技能介质走漏，热紧固即是为避免内部流体走漏而进行的防止作业。<br> 在堵漏方面，它主要因超温、超压、超振荡、超位移、超负荷出产而致使法兰垫片密封或螺栓和螺母衔接有限失效，经过外力加大紧固度，康复密封效果。<br> 四、卡具带压堵漏<br> 卡具带压堵漏通常用在正常出产运转设备上的法兰、管道、阀门等部位，一种是经过打卡子、夹具注胶、填塞、顶压等技能进程完结堵漏。通常是走漏介质处于高温高压向外喷射状况时，制造密封夹具，在走漏部位用夹具密封，将具有固化性、耐走漏介质和温度的密封胶注入密封空腔，使腔内的压力大于体系内的压力，密封胶在必定的条件下迅速固化，然后建立起新的密封构造，到达消除走漏的意图。另一种是经过顶压焊接、引流、内压等技能进程，在走漏区外围制造包套构成一个密封腔，到达消除走漏的意图。<br
