3pe corrosion seamless steel pipe factory outlets in the world torrent vast stirred, Shun prosper against it will perish. I did not forget to grow with international standards in their own, can produce with the American standard, Japanese standard, German standard, such as anti-corrosion steel pipe corrosion can be matched, the true realization of corrosion Without Borders, passed the ISO9001 international quality management system certification, American Petroleum Institute API Spec 5L, 5CT, 5B product certification, ISO14001 international environmental management system certification and GB / T28001 Occupational Health and Safety Management System certification, and special equipment manufacturing license (pressure piping) system certification and licensing *, 2011 May become China National Petroleum Corporation a material supplier. Cangzhou Guanghui marketing manager of a sea abundance in the market to provide you with top anti-corrosion steel products, the most authentic anti-corrosion steel prices. Since the company since its founding, the company conscientious, diligent, sense, the real, the development of new technologies, development of new technology. Anxious customers, what customers are thinking, and some others that we have, we have that others do not. Produced by 3pe anti-corrosion steel, TPEP steel and other corrosion product quality ahead of the industry peers. Grasp the opportunities, in order to capture the market. Guanghui corrosion steel pipe used for: public works: for high-rise building water supply, heat supply network, water supply projects, gas transportation, underground water and other pipelines. Oil: Oil pipeline, chemical, printing and dyeing industry, transport process piping of corrosive media. Sewage: Sewage discharge pipes, sewers and biological corrosion engineering pool Agriculture: Agricultural irrigation pipes, deep well pipes, drains and other Internet 3PE anti-corrosion steel pipe insulation, heat loss of only 25 per cent of traditional pipe long-running or can save large resources, significantly reduce energy costs, and still has a relatively strong waterproof and corrosion resistance, and does not require attached trench, you can directly buy the ground or water, but also in the construction simple and rapid, comprehensive cost is relatively low, at low temperature also has good resistance to corrosion and impact resistance, and in certain circumstances can also be directly buried permafrost. The above is the explanation today about the anti-corrosion steel pipe 3PE theory of knowledge, we want to help 3PE anti-corrosion steel for the transport of crude oil minimum heat loss in the permafrost zone tubes, pipes and prevent heat exchange occurs permafrost , pipelines outer protective coating 3PE external coating using composite polyurethane insulation and polyethylene outer sheath. 3PE coating and a non-polar polyethylene outer protective tube materials, composite coating polyurethane layer polar materials, weak bonding between the two, or melting permafrost heaving heavy process, likely to cause Tu layer shelling, need to be addressed, can be corona treatment. 3PE anti-corrosion steel electric shock corona treatment is a process, the principle is the use of high frequency, high voltage corona discharge on the surface to be processed to produce plastics and low-temperature plasma, these ions into the surface of the body electric shock and damage its molecular material structure, and then oxidizing the surface of the molecule and polarization to be treated, so that the plastic surface to produce free radical crosslinking reaction of the polymer, resulting in increased adhesion ability of the plastic surface. 3PE anti-corrosion outer surface with an outer corona processor, high-frequency voltage source, discharge coil composed of two parts, pipe as a ground pole. Process: water cooled after coating, the outer surface of a corona treatment carried 3PE After air drying, after the completion of, using a special cutting head means, splicing cut. Polyethylene outer sheath tube wall using corona processor inside, from high-voltage power supply, within the corona discharge electrode, outer corona discharge electrode composed of three parts. Process: inner electrode and the outer corona treatment device electrodes were installed on both sides of the inner and outer wall of the outer protective tube, and by moving the tractor pulling. The inner electrode is helical, foreign extremely flat shape, the discharge current is formed through the wall of the discharge circuit, in order to achieve a corona treatment. Corona treatment technology in the application of large pipeline projects, greatly improving the outer protection tube, bond 3PE coating and polyurethane layer between the surface tension coefficient of 52 × 10-5N / cm, the axial shear strength of 0.21 MPA, a coating to prevent shelling, avoiding the formation of an internal loop space, even if the outer protective layer of damaged water case also prevent the spread of water to prevent corrosion perforation. Promote the use of corona treatment is recommended in the relevant project. Can be processed: 2pe / 3pe anticorrosive steel 2PP / 3PP anticorrosive steel FBE / 2FBE anticorrosive epoxy powder cement mortar lined steel coal tar epoxy anti-corrosion steel pipe drinking water, non-toxic epoxy anti-corrosion steel pipe corrosion ipn8710 polyurea epoxy anti-corrosion steel pipe Epoxy resin micaceous iron pipe corrosion corrosion epoxy anti-corrosion steel pipe chlorinated rubber solvent preservative-free products such as anti-corrosion steel pipe HT515 glass flake epoxy anti-corrosion steel pipe corrosion, etc., according to customer needs using a variety of materials seamless steel spiral pipe joints straight steel line pipe and so on. 3PE anti-corrosion steel pipe buried as one of the major oil and gas transmission facilities, carriers, ground engineering. Is connected upstream and downstream users of the resource link, due to long-term pipeline buried in the ground, over time, soil characteristics and terrain outside the settlement and other factors, pipeline corrosion will occur, perforation, leakage, fields and countries serious loss. By the construction, oil and gas pipelines economic losses caused by corrosion can be divided into direct and indirect losses. Direct costs include: replacement of equipment and components, repairs and maintenance and corrosion fees; indirect losses include: loss of production, loss of corrosion products caused by leakage, corrosion product accumulation or loss caused by corrosion damage, indirect losses far more direct large losses, and difficult to estimate. Pipeline corrosion in addition to considering the severe economic losses, but it can also cause leakage of hazardous substances, environmental pollution, or even cause sudden disaster, endangering personal safety. For long-distance transport of natural gas pipelines and pipeline networks, pipeline external corrosion technology adoption and construction quality is directly related to the safe operation and life of the pipeline. Because the pipeline crossing the area with complex terrain, soil properties vary widely, buried steel pipeline external corrosion need to take different measures. The main features of the development pipeline external corrosion technology embodied in the high-performance anti-corrosion materials, complex, long life and good economy.
