It is made of imported butyl rubber, adhesives, fillers and other polymeric anti-corrosion material into the mold made of high-temperature extrusion mixing, each about 0.125Kg, without primer, to borrow liquefied melt baking flamethrower to damage the wound, after cooling can be. Mending rods designed for underground or overhead weld steel pipe corrosion resistance, thermal insulation pipe up hurting Mending, repair corrosion damage PE layer construction, namely polyethylene anticorrosion coating scratches, bumps, bubbles, Mending cuts and other injuries when measured peel strength of repair; high hot melt glue stick and outer PE pipeline corrosion coating bond strength, form a continuous close preservative system, PE melt rods heated in the construction, so that the hot melt adhesive coating layer melts, and Mending site close bond, and the original pipeline polyethylene outer coating is formed integrally bonded pipe evenly wound surface to form a continuous close preservative system can resist soil stress, anti-hydrostatic pressure, resistance to cathodic stripping, resistance to chemical corrosion and mold erosion, providing long-term, effective corrosion protection for steel pipes. Mending stick outer coating is mainly used for pipe repairing scratches, damage the pipeline transportation, handling, installation and testing process is likely to cause the foreign coating, scratch repair after injury with a stick up, stick to play in the pipe surface sealing and antiseptic effect, can be used for anti-corrosion steel pipe repair and mending Mending, such as the point of injury the local area, line scratch small area of ??less than 100mm square injury, three PE pipe used to fill the wound surface defects, with the pipeline Mending Mending piece band to use. Project site, convenient and efficient construction, is the ideal new pipeline Mending repair materials, labor, save time, save money, is home to a large project customers the best choice. Size may be based on the specific requirements of the number of customers custom processing. Franciscan 宁华奕 shelf specifications?, The only specification model 25 * 300, the current Mending rods on the market are produced by my company.
