High frequency welded pipe equipmentThe specific process is as follows: open the end of the steel coil, straighten it and send it to the subsequent equipment. After uncoiling, level the strip steel, cut the head and tail, cut the material with a disc, and then rewind the strip. The raw material is fixed in length and width, and is cut to the corresponding width according to the actual length of the pipe. Type I groove is usually used for welding, which can make the heating uniform along the thickness direction and make the groove preparation easy. After uncoiling, continue to level the strip, cut the head and tail, and cut the butt weld to ensure the continuous production of the forming unit. After passing through the horizontal spiral looper, check whether there are defects in the middle of the strip steel through non-destructive testing, and then store the strip steel in the looper device for use in the forming unit.
The prepared strip steel enters the continuous forming high-frequency welded pipe equipment, and gradually bends under the action of the squeeze roller until it is rolled into a round pipe. The two edges of the strip are heated to the welding temperature by a high-frequency welding machine, and then pressure welded by a squeeze roller. Thereafter, internal and external burrs formed on the inner and outer surfaces of the steel pipe by the extruded molten metal or plastic metal are removed by a deburring device. After a period of air cooling, the welded pipe is water-cooled so that the welded pipe is no longer bent and deformed due to air cooling. The steel pipe section of the extrusion roller has a certain vertical ovality, and the outer diameter is slightly larger than the finished pipe. In order to obtain an accurate outer diameter and cross-sectional shape of the steel pipe, after water cooling, the welded pipe of the high-frequency welding machine must be cold calibrated with a sizing machine. Welded tubes of fixed length shall be cut in motion to a fixed length or double length, subject to the appropriate tolerances.
Due to the maturity and excellent performance of forming welding technology, high-frequency welded pipe equipment has been widely used in chemical, petrochemical, electric power, building structure and other industries. The main function of the equipment is to be used when installing pipes. There are many pipeline products on the market now, and each pipeline has its own characteristics. Pipeline products play an important role in the market and are also necessities in life. In addition, the wall thickness of the pipe is relatively large, which can meet the requirements of the general pipe, and the pipe-making precision is high. Another point is stable performance and high output.
High-frequency welded pipe equipment can be used to weld bimetal composite pipes such as air-conditioning copper pipes and air-conditioning copper pipes, air-conditioning copper pipes and seamless steel pipes. For welding bimetal composite pipe. After welding, the appearance is beautiful, solid, round, evenly heated, and there is no leakage or leakage. The advantages of high-frequency welded pipe equipment at work are also very obvious, such as fast induction heating, high efficiency, energy saving, and low cost compared with oxygen welding. Small oxidation area, energy saving and low cost, small oxidation area, beautiful appearance after welding, uniform heating, and no risk of welding leakage. In fact, the equipment has high efficiency, fast welding speed, 1-5 seconds per tooth, good repeatability, good repeatability per tooth, fast and uniform heating speed, which can effectively avoid cracks caused by sawtooth aging and local overheating, and can also avoid safety hazards such as missing teeth caused by incomplete melting in the melting furnace. High frequency welded pipe equipment with high performance and toughness of the saw tooth woodworking saw blade.
