Yancheng anti-corrosion sacrifice anode magnesium alloy superior quality
镁合金牺牲阳极的施工要求   是牺牲阳极的埋设要求:准备好填料,要按比例配制并调匀,装入直径三十厘米一米长的棉布袋中;按要求将阳极进行表面清洁处理,然后插入准备好的填包料中心位置压实。ISO9000— 效率、效益之源。ISO9000 - the source of efficiency and efficiency. 填包料外面要绑结实,放平或者数值摆放都可以,埋在相同深度,距离被保护管道两到三米的位置,后用准备哈皮的细土掺入盐将阳极坑进行填平。电缆与其他装置连接的时候都要采用锡焊,分线盒内的连接线除外。锡焊接前都要剥去防腐绝缘层,并进行表面清洁处理;焊接完成后的焊接点要做好绝缘防腐处理;电缆的埋设也要与管道的的埋设深度相同。电缆要有足够长的预留大约在零点八米左右,预留长度不能加上保护管,方便日后维护的时候将分线盒提出地面检测数据;分线盒的填埋要填实并且要做防水处理。电缆的颜色要有区分度,阳极选用的埋设位置周围也要有性的标志。lb17184466
国标镁合金牺牲阳极针对套管的屏蔽，大致采用带状锌阳极，螺旋式缠绕在管道上，每隔2m左右与管道焊接一次。随便一个套管处应安装测试桩，通过套管和管道上的测试导线在地面上可以很方便地测试。2.2绝缘连接为避免阴极保护电流流到与大地连接的非保护构筑物上，应对阴极保护管道系统开展电绝缘。这个样子可以预防电流流失，减轻电偶腐蚀，避免用不着的干扰，控制电流流向。
并处于同一电解质中，使该金属（即阳极）上的电子转移到被保护的金属（即阴极）上去，被保护的金属（即阴极）原子不容易失去电子而变成离子（金属腐蚀就是原子失去电子变成离子的过程）其危害具体有两方面，一方面强电线路的交流电压的不断存在会对钢质管道产生了交流腐蚀，二是强电线路发生故障时，会导致瞬间感应电压，一定能击穿管道中设置的绝缘装置，并威胁到人身安全。解决交流干扰的方法有三种，一则管道分期施工全部结束后，一次--性完成牺牲阳极的施工，尽早进行阳极接地，二是加强管道和接地体的距离，至少应达到3m，三是在管道和接地体间，绝缘装置侧向分别串连接地电池，将瞬间感应电压转移到管道上。2.3交流干扰郊区的强电线路对管道存在着交流干扰再通过管道的接地装置将电流散掉，防止故障电流对管道的影响。
The formulation of the Technical Specification for the Procurement of Polyethylene Preserved Materials for Steel Pipeline(Q/SY 1846-2015) will help to further improve and stabilize the quality of polyethylene special materials, lead the sound competition and development of the polyethylene special materials market, and achieve the safety and long-term operation of oil and gas pipelines. It has remarkable economic and social benefits.
The establishment of the long-acting mechanism of pipeline protection has transformed the pipeline protection work into the pre-prevention and effectively protected the immediate interests of residents along the pipeline. While the government and residents along the pipeline share the fruits of the development of oil fields, the initiative and enthusiasm for protecting pipelines have been fully mobilized, the relationship between oil fields has become more harmonious and harmonious, and the protection of the external environment for pipelines has been greatly improved. It has formed a new model of oil and gas pipeline protection that is "the main enterprise, the government, and the Democratic point". In 2015, the Ministry of Oil and Gas Transportation and Marketing was named the model unit for ethnic progress in Xinjiang Uygur Autonomous Region.lb17184466
