Steam pipeline corrugated expanders reduce pipeline vibration and improve efficiency

Steam pipe corrugated expanders are produced online in succession, the thicker the wall thickness, the larger the capital contribution of the unit and dissolving equipment, the less economical and practical it is. The thinner the wall thickness, the lower the input-output ratio; secondly, the process of the product determines its advantages and disadvantages, the general welded steel pipe has high precision, uniform wall thickness, high brightness of the tube appearance (the brightness of the steel pipe appearance determined by the steel plate appearance grade), and can be arbitrarily sized. Thus, it shows its economy and beauty in the use of high precision, low and medium pressure fluids. The tensile strength of steam pipe corrugated expander is higher than that of steam pipe corrugated expander welded pipe. The tensile strength of steam pipe bellows expander is higher than 520 MPa~(316 L) steam pipe bellows expander. The tensile strength of steam pipe corrugated expanders is only greater than 480 Mpa, which is due to the fact that carbon is a strong austenitic constituent element and can significantly advance the strength of steam pipe corrugated expanders. The corrosion resistance and weldability of the steam pipe corrugated expanders are significantly better than the general 316 stainless steel. From the producer's point of view, stainless steel plants are reluctant to produce it due to the low demand for general 316 stainless steel. So the practice circulation in the market is basically low carbon steam pipe corrugated expanders, unless there is a specific demand.
Carbon has a negative impact on the corrosion resistance of stainless steel pipes. Especially the need to weld the stainless steel, after welding low carbon steam pipe corrugated expanders corrosion resistance is lower than 316 stainless steel. Good corrosion resistance function, 316 stainless steel welded cross-section needs to be solid solution annealing treatment after welding. Steam pipe corrugated expanders tube has stronger corrosion resistance, suitable for strong corrosion areas such as the seaside. In most cases, 304 steam pipe corrugated expanders are sufficient to meet the requirements of the application.
