Coating Repair Pod

　　Coating Repair Pod, also known as patching rod, pipeline repair rod, hot-melt repair rod, etc., is prepared by blending and extruding various high-performance materials. When used, it is melted and applied to the damaged area using a liquefied gas torch and then cooled. The repair rod is specifically used for anti-corrosion repair of buried or overhead steel pipelines and insulation repair of thermal insulation pipelines. It is used to repair damage to the PE layer in anti-corrosion construction, such as scratches, impacts, bubbles, and incisions during peel strength testing. The hot-melt adhesive rod has high bonding strength with the outer PE anti-corrosion coating of the pipeline, forming a continuous and tight anti-corrosion system. During construction, the PE melting rod is heated, causing the hot-melt adhesive coating to melt and tightly bond with the repair site, forming a unified structure with the original polyethylene outer anti-corrosion layer of the pipeline. It adheres evenly to the surface of the pipeline, forming a continuous and tight anti-corrosion system that can resist soil stress, static water pressure, cathodic disbondment, chemical corrosion, and fungal erosion, providing long-term effective corrosion protection for steel pipelines.

Guide for application

　　The coating repair rod is mainly used for repairing scratches on the outer anti-corrosion coating of pipelines. It is used to repair damage caused to the coating during transportation, handling, installation, construction, and testing processes. After a scratch occurs, the repair rod is applied to the surface of the pipeline to seal and provide corrosion protection. It can also be used for repairing and patching steel pipelines, such as small area damages with point or linear scratches smaller than 100mm square. It is used to fill defects on the surface of 3PE pipelines in combination with repair patches and repair bands. It is a convenient and fast solution for on-site operations in project engineering and is considered an ideal new material for pipeline repair and patching. It saves labor, time, and money, making it the best choice for large-scale engineering projects both domestically and internationally.
