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.

　　除修復焊接外，對漏液和漏堿的管道也可采取夾箍或箍箍、更換密封件、密封密封劑封堵等措施，但這些都是治標不治本的措施。面對復雜的施工環(huán)境和緊迫的工期要求，往往無法達到要求。

　　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技術是一種時間短、成本低、效果好的成熟修復方法。該材料具有與基材粘結的附著力強，不會產(chǎn)生熱應力，避免后期管道脆性斷裂等優(yōu)點。此外，該材料具有良好的耐高溫和耐腐蝕磨損性能，可廣泛應用于管道堵塞。

　　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聚合物復合材料和“排液法”防止堵塞和泄壓。

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

　　具體維護步驟如下:

　　The specific maintenance steps are as follows:

　　1. 進入現(xiàn)場，做好防護，準備相關工具(記得戴手套);

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

　　2. 對漏液、漏堿管道、三通、焊點進行表面處理，表面污垢、銹跡;

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

　　3.觀察表面泄漏位置，根據(jù)實際泄漏情況調(diào)整物料;

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

　　4. 按比例混合納米碳素聚合物材料，涂敷在泄漏部位的表面。初凝后觀察物料是否完全堵塞，確保無泄漏點;

　　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. 排放和密封泄漏點，并完成處理。

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