Why do carbon steel elbows require sandblasting? A deep analysis of the key value of surface treatment

In numerous industrial fields such as petrochemicals, power and metallurgy, urban heating, and shipbuilding, carbon steel elbows are indispensable connecting components in pipeline systems. They change the direction of the pipeline and bear the erosion from the medium and pressure fluctuations. However, observant engineers will notice that almost all qualified carbon steel elbows undergo a seemingly "rough" but crucial process - sandblasting treatment - before leaving the factory or during installation. Why do carbon steel elbows need sandblasting? What problems does this process solve? This article will comprehensively answer this question from multiple dimensions such as material properties, process requirements, quality control, and anti-corrosion performance. I.
