Pre-bowing and measuring are the fundamental stages in the winding cylinder framing process. The principal motivation behind pre-twisting is to take care of the bounce back issue of the cylinder clear, in light of the fact that the size of the bounce back straightforwardly influences the characteristic nature of the steel tube; the primary reason for the measuring is to get a more exact measurement of the cylinder, in light of the fact that the breadth control is the vitally quality record of the steel tube. one. A reasonable match between pre-twisting and estimating is expected to get an ideal steel pipe clear.
Coming up next is a short conversation on the development cycle and qualities of lowered bend welding of stirred twisting steel pipes with 630*3 ribs. The rule of lowered curve welding: Lowered circular segment welding is the 1215 steel of circular segment nuclear power welding, and manual welding pole bend welding is unique: the lowered circular segment welding of the welding wire is uncovered, there is no covering, lowered curve welding is without a doubt pre-cleared welding motion to be welded The lowered circular segment welding wire stretches out into the transition, and the curve is framed under the transition. The development cycle of the lowered curve welding is to such an extent that the welding wire is in touch with the workpiece. After the beginning button is squeezed, the welding wire and the workpiece are invigorated, and the welding wire is returned. Pulling out, the bend lights, the welding carriage propels, the welding wire is consistently conveyed downwards, the curve is kept up with to consume under the motion layer, and the welding pool is framed beneath the circular segment. Around the bend, the transition melts to shape a cavity. The pit and the pool proceed to progress, and the metal behind the pool hardens to frame a consistent weld. This cycle is performed under the transition, so we can’t see it with the unaided eye. It tends to be seen with X-beam photography. Since the winding steel pipe embraces the welding innovation of lowered curve programmed welding, other than this sort of high creation proficiency; the creation helper time is less, the ideal opportunity for changing the welding bar is saved; the welding conditions are perfect and no scatter, and the cleaning time is saved; the nature of the welding crease is high. It additionally gives the fundamental circumstances to the conveyance of the winding welded pipe plant, so the creation season of the huge twisting steel pipe is ensured, so it is still broadly utilized.
1. The tension bearing liquid is basically utilized for the X46 welded pipe as the cylinder clear, and is much of the time spirally framed in temperature. It is utilized for welding with twofold sided lowered bend welding and is chiefly utilized for winding crease welded steel pipe gadgets for pressure liquid transportation. The capacity of the steel line to endure pressure areas of strength for is the welding execution is likewise awesome. After various thorough logical assessments and tests, the utilization circumstance is somewhat protected and solid. The strong measurement of the steel pipe is huge, the transmission productivity is likewise high, and it can actually save the speculation of laying pipelines. It is mostly utilized for pipelines that transport oil and flammable gas.
2. General low-pressure liquid vehicle is fundamentally hot-moved steel wound tube spaces, frequently temperature twisting embellishment, utilizing high-recurrence lap welding strategy for general low-pressure liquid conveying winding crease high-recurrence welded steel pipe. Welding steel with twisting welds.
3. The hot moved steel strip is utilized as the cylinder clear, which is in many cases framed by twisting embellishment and is made of twofold sided lowered bend welding or high-recurrence welded steel pipe. It is utilized for the establishment heap steel pipe for common structure designs, wharves, and scaffolds.
4. The general low-pressure liquid vehicle is hot moved steel strip curled tube, customary temperature twisting embellishment, utilizing twofold sided programmed lowered curve welding or single-sided welding technique for water, gas, air and steam and other general low-pressure liquid vehicle Lowered circular segment welded steel pipe.
5. The tension liquid vehicle depends on the hot-moved steel strip for tube spaces, customary temperature winding embellishment, high-recurrence lap welding strategy utilized for pressure liquid transmission twisting crease high-recurrence welding steel pipe gadget. The steel tube serious areas of strength for has bearing limit and great pliancy, which works with welding and handling. After different severe and logical reviews and tests, the utilization of protected and solid, huge distance across steel pipe, transmission productivity is additionally high, and can successfully save the laying pipeline venture. It is essentially utilized for the laying of pipelines associating petrol, flammable gas, and so on.
