Leakage occurred in the weld joint of a certain liquid alkaline pipeline in an enterprise. The medium was 32% liquid medium. Temperature 85 ℃, pressure 0.6 MPa, pipe diameter 100 mm, material 316L. Therefore, the enterprise carried out welding in the process of maintenance and found that the problem was not solved, but the problem became more serious after the start-up. There are some intergranular cracks in the leakage point from 3 to 6.

　　除修复焊接外，对漏液和漏碱的管道也可采取夹箍或箍箍、更换密封件、密封密封剂封堵等措施，但这些都是治标不治本的措施。面对复杂的施工环境和紧迫的工期要求，往往无法达到要求。

　　In addition to repair welding, clamp or hoop, seal replacement, sealing sealant sealing and other measures can also be taken for the pipeline with leakage of liquid and alkali, but these are all measures to cure the symptoms and not the root cause. In the face of complex construction environment and urgent construction period requirements, it is often unable to meet the requirements.

　　Solay技术是一种时间短、成本低、效果好的成熟修复方法。该材料具有与基材粘结的附着力强，不会产生热应力，避免后期管道脆性断裂等优点。此外，该材料具有良好的耐高温和耐腐蚀磨损性能，可广泛应用于管道堵塞。

　　Solay technology is a kind of mature repair method with short time, low cost and good effect. The material has the advantages of strong adhesion with the base material, no thermal stress and avoiding brittle fracture of the pipe in the later stage. In addition, the material has good resistance to high temperature and corrosion wear, which can be widely used in pipe plugging.

　　采用Solay聚合物复合材料和“排液法”防止堵塞和泄压。

　　Solay polymer composite material and "drainage method" are used to prevent blockage and pressure relief.

　　具体维护步骤如下:

　　The specific maintenance steps are as follows:

　　1. 进入现场，做好防护，准备相关工具(记得戴手套);

　　1. Enter the site, do a good job in safety protection and prepare relevant tools (remember to wear gloves);

　　2. 对漏液、漏碱管道、三通、焊点进行表面处理，表面污垢、锈迹;

　　2. Carry out surface treatment for leakage liquid and alkali pipeline, tee joint and welding spot, and remove surface dirt and rust;

　　3.观察表面泄漏位置，根据实际泄漏情况调整物料;

　　3. Observe the leakage position of the surface and adjust the materials according to the actual leakage situation;

　　4. 按比例混合纳米碳素聚合物材料，涂敷在泄漏部位的表面。初凝后观察物料是否完全堵塞，确保无泄漏点;

　　4. Mix the nano carbon polymer materials in proportion and apply them on the surface of the leaking part. After initial setting, observe whether the material is completely blocked to ensure there is no leakage point;

　　5. 排放和密封泄漏点，并完成处理。

　　5. Discharge and seal the leakage point, and complete the treatment.
