I. Introduction of steel-lined ultra-high-polymer polyethylene composite pipe Ultra-high-density polyethylene composite pipe (HUMWPE/GY) is an excellent new-type composite pipe lined with an ultra-high molecular weight polyethylene pipe with a steel pipe as the outer protection substrate. It is a new type of pipe that combines pressure resistance, wear resistance, corrosion resistance, and impact resistance. At present, it is at an advanced level in the country and is being gradually recognized by a large number of users. Its rigidity and flexibility have successfully solved the installation and use of industrial pipelines. A series of difficulties and problems encountered in the process, the product can meet the different needs of the various products in the environment, expanding the pipe applications.
Second, steel-lined ultra-high molecular polyethylene composite pipe product performance The product due to the full use of the steel pipe and ultra-high molecular weight polyethylene pipe composite properties, it has significant advantages:
1. The outer layer of the product is a steel pipe, which has strong impact resistance, high pressure resistance, prevents creepage of the inner liner, and has a very wide use space in the industrial pipeline.
2. The product lined with ultra high molecular weight polyethylene pipe has excellent wear resistance, pressure resistance and corrosion resistance. Chemical stability, not scaling, smooth inner wall. The friction coefficient is small, the pressure loss is small in the process of fluid transportation, the transportation cost is reduced, and the delivery efficiency is greatly improved. The wear resistance is 4-7 times that of the steel pipe.
3, good insulation, because the thermal conductivity of this pipe wall is less than 10,000 times smaller than steel, can greatly reduce the pipe transportation insulation requirements, its temperature performance in the -50 ° - -80 ° use of good performance, which for The fluid transport in the cold area is of great significance.
4, long service life, the product combines the advantages and characteristics of two kinds of pipe in one, greatly improving the service life, at present is Other high-tech products unmatched by pipe.
Third, steel-lined ultra-high polymer polyethylene composite pipe product applications 1, the product is mainly used for a variety of corrosive, wear-resistant, structural medium medium pressure, high pressure fluid pipeline.
2. The product can also be used for long-distance transportation of centralized conveying pipes. Such as: thermal power plant fly ash transport, coal slurry transportation, all kinds of metal mines and chemical mines, slurry, tailings and mud transportation, the effect is good.
3. The product can also be applied in long-distance fluid transportation in heavy medium, such as coal preparation plant, coal washing plant, concentrator and various river dredging projects, etc. The application field is very broad.
Fourth, steel-lined ultra-high polymer polyethylene composite pipe connection and installation The product is mainly used flange connection, easy to disassemble, easy to unload, easy to install, pipe section connected without any anti-corrosion seal, reducing the fault point in the pipeline, Easy to maintain, greatly reducing installation and maintenance costs and improving economic efficiency.
