Mending piece CPR is a special polyethylene coating for steel pipeline Mending design and development of radiation crosslinking Mending film. It is made of radiation crosslinked polyolefin substrates and special hot melt adhesive sealing composite. Mending piece in the construction of heating, the special hot melt adhesive coating melts, and Mending site close bond, and the original pipeline polyethylene outer coating is formed integrally evenly coated surface of the pipe to form a continuous close preservative system, soil stress resistant, anti-hydrostatic pressure, resistance to cathodic stripping, chemical resistant and corrosion-shaped mold for a variety of erosion, provide long-term, effective protection for steel pipes. Polyethylene pipe repair external coating covering film is mainly used for corrosion protection and triple layers of polyethylene corrosion during transportation, inspection and construction process caused the local area, such as the point of injury, the line of small scratches less than 100mm square area of ??damage. Features: - High mechanical strength, anti-aging ability. - Good resistance to environmental stress performance. - Excellent adhesive properties. - Easy to use. Mending Mending stick ?? 3PE 3PE coating stick is dedicated Mending hot melt glue stick. Mending rods also called patching rods, the product is mainly used for pipes with outer scratch repair, used for pipeline corrosion polyethylene coating finish in the transport, handling, installation and inspection process to repair damage caused, stick in play the pipe surface sealing and antiseptic effect, dedicated to the steel pipeline corrosion repair and mending Mending. Features: Mending stick uniform appearance, anti-infiltration, anti-aging, chemical resistance, adhesive power, environmental adaptability, easy operation, anti-cathode stripping, anti-corrosion behavior of many Chinese chemical corrosion and mold. Applications: suitable for various types of corrosion damage to goods in the pipeline transportation, handling, installation and testing project due for repair.
