Cutting method of 304 stainless steel plate

2023-03-21
Longitudinal welded pipe is a kind of welded 304 stainless steel plate. All welded steel pipes are made of steel strip or steel plate after bending and welding. Longitudinal welded pipes are divided according to the weld form of welded pipes. In addition to straight seam welded pipes, there are also spiral steel pipes. Under normal circumstances, the value of welded pipe is to transport low-pressure liquid, so there are very strict requirements on the production process and material selection, such as bending, hydraulic pressure, flattening, etc. before forming the steel pipe. These projects are just experimental steel pipes Whether there is enough standard to be made into welded pipe. In fact, the straight seam welded pipe is a little troublesome in practical application, because the welded pipe is relatively large, so it may not be suitable to buy it from the market. It is either too long or too short. If it is too short, it can be welded again. In this case, the excess part needs to be cut off. In fact, this also reflects the relatively strong plasticity and practicability of the straight seam welded pipe, because the straight seam welded pipe can only work normally if it is made into a length suitable for construction.

In general, there are many ways to cut large-diameter longitudinally welded pipes. The common ones are artificial gas cutting, pipe self-propelled automatic cutting machine, sawing machine, etc. The efficiency of artificial gas cutting is relatively fast, but it will leave gaps at the incision. There are traces of zigzag shape, so it is not suitable for projects with strict construction requirements. Cutting straight seam welded pipe with sawing machine can cut a relatively smooth and neat cut, which is conducive to welding with other steel pipes during construction, but the cutting efficiency is relatively low. The self-propelled pipe cutting machine is the best, it can cut neat cuts like a sawing machine, and it is also much more efficient than artificial gas cutting, and it is also the cutting method with the lowest cost for 304 stainless steel plates.
