Steel Pipe Coated With The Development Of The Key Components Of The Oil Machine

Steel pipeline transportation is one of the five typical methods today. It becomes the main means of transportation of oil and natural gas. Collectively referred to OCTG as casing and tubing pipe, oil and gas well casing is a supporting wall of the pipe, and can be divided into surface casing. The casing and production casing technology; tubing cementing oil and gas wells, after playing in the reservoir casing set, let the influx of oil and gas from the ground, exclusive seamless pipe. Corrosion resistance of steel channel, based on the shortcomings of poor domestic large steel plants in order to improve the service life of steel pipes and to meet its products meet export requirements, a process pipe factory is the last of its outer surface anti-fouling paints (mostly 6 #,10 # paint)-type high-pressure airless spray. Mechanical products mechanical production of the paint is an important and indispensable process, both to protect the product against corrosion important method, but also decorative landscaping products, enhance the appearance of the product is an important tool. Paint equipment painting occupies an important position, paint equipment, good or bad, will directly affect the product coating quality, working conditions, the use of paint, energy saving and environmental protection and so on. Automatic spraying of the outer surface of steel pipe, steel pipe coating before the coating after the vertical conveyor, stepping, horizontal conveyor and drying production line, can be a long time continuous operation, shorter time cost, saving paint consumption, greater range of work, and operated safely and reliably. Pipe to be developed Oiler host and auxiliary equipment is divided into two parts, the host, including: coatings to add storage transportation, heating, insulation and electrical heat tracing loop insulation, boxes and moving rise-fall spray gun group, paint recycling, air and exhaust gas treatment (except paint mist, adsorption, silencers and wind Road); auxiliary include:from the rolling mill out of the vertical pipe conveying, stepping mechanism, horizontal transfer and drying, the final discharge. Electric control system adopts PLC control. Steel exports to go through the American Petroleum Institute API Certification (API 5CT and API 5L), the study of this topic Oiler Pipe Production Line Steel Pipe Factory is the American Petroleum Institute API to obtain the necessary condition for certification. Oiler mainframe using high-pressure airless spray design, in the form of a variety of spraying methods, high-pressure airless type spray is currently home to more advanced coating technology, which is the use of a special form of pneumatic, electric or other power-driven paint pump, will paint to high-pressure, through a narrow nozzle out, the dramatic expansion of paint, so paint the formation of very fine line of mist fan, fog flow, high-speed, wherein the workpiece surface to form the coating method of coating. Airless spray, due to the high pressure of paint, and paint there is no air, so that in less than conventional air spray can be overcome, resulting in improved coating quality, lower cost, but also reduce pollution and improve the working environment for workers.
