Stainless steel, with its excellent corrosion resistance, abrasion resistance, heat resistance, and its shiny, luxurious surface, and are widely used in various fields of the national economy.
Lack of limited by the resources of our NI, relies heavily on imports of stainless steel demand, the price is more expensive, the popularization and application of stainless steel to a certain extent by with constraints.
Carbon steel, especially the Q series carbon structural steel, with high bending strength, good impact resistance and anti-fatigue limit, as well as low prices, thus making it the basis of the national economic construction materials, carbon structural steel, its main elements Fe metal reactivity, oxidation in the atmosphere, it is easy to rust, let alone in a corrosive medium or special (wet, dark) environment. Year for its anti-corrosion investment as well as economic losses because of its natural corrosion, several hundred billion yuan, due to corrosion and are too numerous to lead to a major accident.
Two metal materials of stainless steel and carbon structural steel, using high-tech plastic pressure synchronous composite, composite field of new materials is a major innovation without glue pressure stainless steel composite pipe (Stainless Steel / Carbon Steel Clad Pipe) not only significantly improve the law system steel pipe surface defects and the use of performance, and both good stainless steel corrosion abrasion resistance and excellent appearance gorgeous appearance, is the perfect combination of decorative and load, energy-saving and low-cost organic unity, in line with the composite materials industry policy to develop the country, thus by all levels of government attention and support.
The new material is made of non-destructive pressure synchronously. It has stainless steel corrosion-resistant and wear-resistant appearance and excellent appearance. It also has good bending strength and impact resistance of carbon steel.
In line with the principle of national energy conservation and popularization. The stainless steel composite pipe was officially promulgated in the 2002 national standard GB/T18704-2002. The stainless steel composite pipe has high technical content, precise equipment, advanced technology and stable product quality, and is automatically controlled by computer. The product has the characteristics of pure stainless steel appearance, beautiful appearance and high strength of ordinary carbon steel pipe. Its price is lower than that of pure stainless steel pipe, which is a substitute for the price of stainless steel structural decorative pipe. Products are widely used in municipal public works construction, steel structure, grid construction, petroleum and petrochemical, municipal facilities, road and bridge guardrail, highway traffic engineering construction; construction and decoration engineering construction; sports facilities construction traffic grid, railway isolation network, construction Decoration, street lamps, stop signs, steel grids, furniture, vehicle and ship manufacturing, urban pipe network, oil and gas transmission, motorcycle bumpers, drying racks, bicycle handlebars, etc.

The manufacture of stainless steel clad steel plate is made of base steel plate and multi-layer steel plate, and is prepared by hot rolling and compression welding-hot rolling method.
The surface of the composite layer must be polished or pickled, passivated and delivered.
The surface is smooth and flat, the composite layer is firmly combined, the shear strength is high, and the cold bending performance is good. The stratified layer is resistant to atmospheric, acid, alkali and other media corrosion, has no tendency to intergranular corrosion, and can meet the requirements of corrosion resistance of the structure and the corrosive medium; the base layer can meet the structural requirements for rigidity and weldability. Can save a lot of stainless steel and reduce structural costs.
Mainly used in the chemical, petroleum, pharmaceutical, food, seawater desalination, nuclear industry and other departments to manufacture corrosion-resistant general containers, pressure vessels and other equipment.
The transportation of pulverized coal, ash, mud, lime gypsum slurry, etc. in the metallurgical and electric power industries requires a large amount of metal pipes to be consumed each year. The ceramic composite pipe is used to replace other pipes, and has the characteristics of high wear resistance, long service life, convenient installation and remarkable economic benefits. Shandong Liaocheng Changrun Thermal Power Plant, Liaocheng Zhonghua Power Plant, Beijing Beixin Building Materials Group, Henan Hebi Power Plant, Gansu Pingliang Power Plant, Taiyuan Coal Preparation Plant, Hunan Shimen Power Plant, Hebei Jinniu Energy Co., Ltd. Gequan Coal Preparation Plant, Xingtai Coal Preparation Plant When it is industrially operated, its operating life is ten times or even dozens of times that of steel pipes.
(1) Mine: Mine filling, concentrate powder and tailings transportation are seriously worn on the pipeline. The used powder conveying pipelines such as Panzhihua and Daye Mine have been used for less than one year. About 5 times.
(2) Coal: The coal transportation and long-distance pipeline coal transportation are generally carried out by wet method. The conveying pipe is required to be both wear-resistant and corrosion-resistant. The pipe can be used as a long-life conveying pipe with considerable economic benefits.
(1) The tube does not contaminate or adhere to the molten aluminum liquid. It is an ideal material for manufacturing aluminum melting equipment, aluminum liquid conveying pipe and liquid lifting pipe which are sensitive to iron pollution and require heavy labor for finishing and maintenance after use.
(2) The tube has good wear resistance and heat resistance. It is suitable for conveying corrosive media containing corrosive materials of solid particles as well as high temperature corrosive gases and hot water containing sulfur.
Stainless steel composite pipe is made of stainless steel and carbon steel two kinds of metal materials with new materials nondestructive pressure synchronization into the compound, both stainless steel corrosion and excellent wear and beautiful appearance, good bending strength and impact resistance of carbon steel. Conforms to the national energy conservation and the universal principle.
Stainless steel composite pipe in 2002 GB/T18704-2002 national standard formally promulgated, choose from the quality of materials, inspection and other aspects have a set of strict management, due to the advantages of beautiful appearance, low price, which has been widely used in bridge guardrail, decoration, vehicle accessories, conveying roller, the field of textile machinery accessories etc.
