High wear-resistant steel-plastic composite pipe

High wear-resistant steel-plastic composite pipe

Product features: (innovation point of high wear-resistant steel-plastic composite pipe)

(1) Achieved a breakthrough in the viscosity average molecular weight of ultra-high molecular weight polyethylene pipes

The wear resistance of ultra-high molecular weight polyethylene pipes is closely related to the viscosity-average molecular weight of raw materials. With the increase of the viscosity-average molecular weight, the wear resistance of the pipe is correspondingly enhanced, but at the same time, the processing technology is more difficult. At present, most domestic enterprises can only complete the processing and molding process with a viscosity average molecular weight of less than 2 million. Through independent innovation, our company improves and innovates the production formula and extrusion process, and develops a molding process for ultra-high molecular weight polyethylene raw materials with a viscosity average molecular weight of 9.2 million. The technology is at the leading level in the world.

(2) Achieved a breakthrough in the caliber of high-ultramolecular-weight polyethylene pipes

UHMWPE materials have poor processing fluidity, and the larger the caliber, the more difficult it is to extrude. The company has continuously improved the production equipment and processing technology, and successfully produced the world's largest caliber 1200mm UHMWPE pipe. This technology ranks in the leading position in the world.

(3) Achieved a breakthrough in the ultra-thin wall thickness of large-diameter ultra-high molecular weight polyethylene pipes

The lining pipe of the high-wear-resistant steel-plastic composite pipe adopts ultra-thin wear-resistant ultra-high molecular weight polyethylene pipe. When producing pipes with an inner diameter greater than 700mm and a wall thickness less than 12mm, ultra-high molecular weight polyethylene is very difficult to form. The company through technological innovation , to realize the production of large-diameter ultra-thin ultra-high molecular weight polyethylene pipes, and this technology is at the international leading level.

(4) Solved the problem of high wear-resistant steel-plastic composite pipe in the production process

During the production and processing of high-wear-resistant steel-plastic composite pipes, through the improvement of product structure and the improvement of production technology, the processing problems caused by the inconsistent thermal expansion and contraction coefficients of steel pipes and ultra-high molecular weight polyethylene pipes have been successfully overcome, avoiding After the steel-plastic pipe is disassembled, it is difficult to re-install the counterpart, which realizes the convenient and quick connection of the pipe during the construction.

Application advantages:

The high wear-resistant steel-plastic composite pipe combines the characteristics of ultra-high molecular weight polyethylene pipe and carbon steel pipe into one. While inheriting the excellent characteristics of ultra-high molecular weight polyethylene pipes, it also has the excellent mechanical properties of traditional carbon steel pipes. Widely used in long-distance water supply and drainage projects, dredging, dredging, mud mortar, thermal power plant mortar, mine tailings, coal preparation plant pulverized coal, coal-water slurry and other high-pressure transportation fields.

Engineering construction:

The high wear-resistant steel-plastic composite pipe adopts the flange connection method, and the pipe connection is completed by fastening the flange with bolts. It has a series of advantages such as fast connection speed, convenient connection and disassembly, high strength, and good sealing performance.

1. High construction efficiency

Traditional steel wear-resistant pipes have a series of shortcomings such as easy corrosion, heavy weight, difficult loading and unloading, and low construction efficiency; ultra-high molecular weight polyethylene wear-resistant pipes are light in weight, strong in flexibility, and easy to load, unload, transport, install and use, greatly improving Improve engineering construction efficiency and reduce transportation and installation costs.

2. Fast and convenient connection

The ultra-high molecular weight polyethylene wear-resistant pipes are connected by flanges, which are fixed by bolts through the flanges of the pipes, which have the advantages of fast connection speed, convenient disassembly, high strength, and good sealing performance; Routine maintenance and repair greatly reduce installation and maintenance costs and improve economic benefits.

3. Low maintenance cost

The ultra-high molecular weight polyethylene wear-resistant pipe has excellent wear resistance. Under the same use conditions, the service life is much longer than that of traditional steel wear-resistant pipes, which can effectively reduce the reverse maintenance work during use and prolong the replacement of pipes. cycle, reducing the overall cost of the project.

The ultra-high molecular weight polyethylene wear-resistant pipe has good anti-adhesion, and it is not easy to scale during the operation of the pipeline, which avoids the pickling treatment during the operation.

Ultra-high molecular weight polyethylene wear-resistant pipes have good corrosion resistance characteristics, which can avoid corrosion-resistant maintenance during the use of pipes.
