Guanghui Industry. For decades has focused steel 513. pipe coating you do best partner! 3pe corrosion pipe is a use of a wider pattern of anti-corrosion steel in pipeline also has his shadow. General 3pe anti-corrosion steel is corrosion-resistant steel tube if you do not go inside the liquid acid corrosion is not done deal. If the water pipeline is not the same water contains a lot of corrosive chemical composition of corrosion of carbon steel pipe enough so we must again to the inner wall embalmed. This will not only be able to achieve the preservative effect of external internal corrosion may also be safe to use the. 2pe 2PE anti-corrosion steel pipe anti-corrosion pipeline corrosion is one of the common forms of corrosion, the following were some introduction 2pe corrosion. First: 2PE anticorrosion Overview PE pipe corrosion story structure, the first layer of adhesive (AD170 ~ 250um), a second layer of polyethylene (PE1.8 ~ 3.7mm), two kinds of integrated material, the thickness of layers with three PE same thickness: 1.7-3.8 diameter range Φ25 ~ Φ2420 second: 2PE corrosion advantages 1, pe pipeline corrosion with high tightness, 2, strong corrosion resistance, simple construction side has speed, service life up to 30 - 50 years. 3, at low temperatures also have good corrosion resistance and impact resistance, PE, low water absorption (less than 0.01%). 4, along with high strength epoxy, PE hot melt adhesive, low water absorption and good flexibility, high corrosion reliability, 2PE corrosion steel is widely used in natural gas, petroleum, chemical, electric power, heat, water, steam heating, power generation, water and other long-distance pipelines. 3pe corrosion pipe 3PE preservative composition generally consists of three layers: a first layer of powder epoxy (FBE> 80um) a second layer of adhesive (AD) 170 ~ 250um third layer of polyethylene (PE) 1.8 ~ 3.7mm, the thickness can follow Engineering requirements, the actual operation will be integrated mix of three materials, through processing and steel making firm to form an excellent coating. Its processing methods are generally divided in two and wound sheathed round mold. 3pe anti-corrosion steel is divided into ordinary level and strengthen the level two levels, pipe diameter range of Φ25 ~ Φ2420, pipe wall thickness range between 2.5-30mm, which is relatively good corrosion protection methods. 3PE anti-corrosion steel production processes used called the FBE / extruded polyethylene sheath structure, which combines the excellent performance of epoxy-coated and extruded polyethylene coating of the two, the epoxy coating interface Features and advantages of the chemical resistance and mechanical protection properties of extruded polyethylene coating such as the combination to significantly improve their performance. Therefore, 3PE coating is ideal outer protective layer of buried pipeline, the useful life of more than 50 years. In a domestic 3PE (three-layer structure of polyethylene coating technology) pipe manufacturing enterprises have been successful use of oil and gas pipelines are made of corrosion performance indicators have reached the national standard. Cangzhou Guanghui Industry Co., Ltd is a professional Hebei 3PE anti-corrosion steel manufacturer, to strengthen the level of natural gas with 3PE anti-corrosion steel, Shanxi strengthen the level 3PE anti-corrosion steel, water supply 3PE strengthen the level anti-corrosion steel, gas conveying 3PE anti-corrosion steel, heating network Heating with 3PE anti-corrosion steel, 3PE anti-corrosion steel to strengthen the level, my company to high-quality seamless steel pipe, straight seam steel pipe, spiral pipe as a substrate, processing 3PE anticorrosion seamless, 3PE anticorrosion straight seam steel pipe, 3PE anti-corrosion spiral steel pipe 3PE First, anti-corrosion steel is widely used in Europe, praised by users, it is the most used line coating system. China National Petroleum Corporation in the summer of 1994 decided to introduce 3PE coating operation and coating techniques, for the upcoming start of the Shaanxi-Beijing gas pipeline and Ku-Shan pipeline external corrosion coating. In December, the Central Bureau of oil infrastructure, Pipeline Bureau, Sichuan Petroleum Institute, the headquarters of Northwest Pipeline joint delegation of experts to the United States, Italy, Turkey and other countries to study 3PE coating operation line. May 1995, the Liaohe oil company responsible for the construction of a tender from the Canadian Labour root of the first companies to introduce a line of 3PE coating operation. In early 1996 put into normal production. In 1996 the Italian company Sauk Sam Liu Chang joint venture with Harbin plastic Shuozhou preserving plant actually transform normal production in May. Northwest Pipeline joint venture with Hong Kong headquarters from the Netherlands to introduce 3PE coating operation line, in 1996 in Baoji Yadong preservative company put into operation so far, 3PE anticorrosion get attention and application in China. Starting from Shibuya ninglam pipeline construction, through the tender, plus all domestic 3PE anti-corrosion materials, 3PE anticorrosion prefabricated prices dropped significantly, from the beginning of the era of domestic 3PE preservative widely used, so far 20000KM external corrosion of buried steel pipe 3PE preservative use coating. Currently there are hundreds of 3PE coating operation line, with the processing Φ25-2800mm 3PE steel pipe coating capacity. A little story: train brakes: people time to cavalry invention reins: 2015-03-02 Author: Unknown 2 Views: 735 times early 19th century, steam-powered train appeared. In a "train Contest" held in 1829, Stephenson driving a fully loaded "Rocket" locomotive, at a speed of 56 km has created the first land vehicle running speed. Shortly thereafter, the roar of the train began to Mercedes-Benz in the United States and continental Europe. The formation of a new era of rail transportation industry to flourish. However, when the train is still not perfect. Fatal drawback is the brake ineffective, often leading run accident. In the eyes of the general public, the train is an unsafe vehicle, it was jokingly called "marching wheels Hunshimowang." At that time the train brakes very primitive, initially only the head mounted on the vehicle, complete with driver's manual brake lever is pulled to brake hard to make a heavy train to stop quickly. Later improved to each car is safe in a separate mechanical brake, it is equipped with a special system to mobilize, in circumstances, signaled by the driver, and then blasted each brakeman took brake handle. Although this is slightly better, but still not quickly stopped the train. Therefore, to invent a sensitive and effective train brakes, the railway system has become a big problem to be solved. Many people have committed to improving the research train brakes, but no one thought that the ultimate success is a poor young Americans - Westinghouse, he invented a sensitive and reliable air system brake, to train this horse huge unruly "Iron Horse," the Department on the "reins" in the history of railway transport safety erect a memorable milestone. Westinghouse idea of ??the invention of new train air brake, by one incident excitation up. He said in a trip, just to catch a serious crash caused because the train brakes ineffective. Witnessed a car crash tragedy, he was became determined to invent an effective brake to avoid traffic accidents, protect the safety of rail transport. He first thought of steam. Since it is a steam-driven train, why not use steam to brake? He devised a means for the boiler and the piping connecting each car and tried to drive steam cylinder piston, thereby pressing the brake shoes, to brake purposes. However, due to rapid pressure steam is condensed in a long line, the loss of pressure, the experiment failed to achieve the desired results. Westinghouse is unable to do anything when, one day he accidentally bought a "Life Times" newspaper, reported that a French cut Cenis Tunnel, introduce the air drive a large drilling machine message makes him think of wrestling with cord Brake: Since compressed air can be driven drills, digging hard rock, may also be able to drive the train brakes. Based on this idea, Westinghouse has finally made a new type of air brake. The principle is not complicated, as long as the addition of a motorcycle driven by the air compressor, compressed air is sent through the pipeline each cylinder car on the line. When the brakes, as long as one to open the valve, the compressed air pushes the piston of each cylinder car, the brake shoe pressed to stop the train quickly. In 1868, only 23 years old Westinghouse Air Brake has achieved patent, composed of Westinghouse brake companies. Until today, the air brake is still security train and bus operation.
