Low sales 3pe corrosion seamless steel pipe 3pe corrosion, corrosion of steel price TPEP must provide detailed technical parameters, pipe, specifications (including pipe diameter, material, thickness), whether the number and quotes require EXW etc. With these parameters, we adopted the accounting technical parameters in quotes, to provide the more detailed, the more accurate our offer. Since the industrial revolution, the world's manufacturing industry followed them into the industrial age, the demand for energy remains high. Energy pipeline emerged, but different energy complex chemical composition, there is some corrosion on the pipeline, the pipeline is a flawed life. Pipe corrosion occurs, extending the useful life of pipelines, for saving energy, reducing waste potentially play a role not to be underestimated. Members comrades attention! Members comrades attention! Here Guanghui play a preservative notice: 3pe, TPEP, ep, coal tar epoxy, ipn8710 series have internal and external anti-corrosion steel 3pe quantities, the real gold is not afraid of fire, seeing is believing. Samples can express, welcome to plant inspection. To pipe corrosion adhesive tape products are mainly polyethylene anticorrosion tape, polypropylene fiber corrosion tape, polyethylene anticorrosion tape 660, coal tar epoxy cold tapes, including polyethylene and polypropylene fiber corrosion corrosion tape application tape maximum range, fully able to meet a variety of pipeline corrosion engineering. Has a strong bond with the adhesive backing, good impact resistance and good match with cathodic protection, etc., have used in North America, South America and some domestic pipeline project. Three-tier structure of polyolefins (3PE anti-corrosion steel) is developed in Europe in the 1980s and the beginning of the successful use of, it is the high permeability FBE good corrosion resistance, adhesion, and high resistance to cathodic stripping polyolefin materials resistance, good mechanical properties and resistance to soil stress corrosion properties combine structure, once came to the project has been in many applications, especially in European countries, and its application showed a rising trend. PE is the bottom three layers of epoxy coating, a polymer adhesive intermediate layer, the surface layer of a polyolefin. Adhesives may be modified polyolefin containing a polar group grafted to a polyolefin main chain carbon bond. Thus, both the adhesive and a surface-unmodified polyolefin blending, and of using a polar group with the epoxy resin curing reaction. This combination of characteristics is to achieve the best bond strength between the three coatings, while the performance and characteristics of the layers of paint so get three complementary. It is characterized by high cost and complex process. In real life, the impact of external environment on the 3PE considerable corrosion of steel, such as the layout of the various processes, equipment selection, surface quality, heating, painting temperature, cooling, transmission accuracy, material properties and testing. Poor control will result in a small coating adhesion, too thin, cracks or bubbles and other defects, strict implementation of norms and methods of scientific work is critical to control deficiencies and ensure yield corrosion pipe. Chinese patent CN2007100572363PE.9 (a water cooling pipe coating method) announced a steel outer annular cooling device, the cooling effect is improved, but still can not overcome external cooling method leads to quality defects and weld coating thickness fundamentally thinning. The ideal way to reduce 3PE anti-corrosion steel coating thickness reduction is cooled from inside the pipe.
