Stainless steel seamless elbow is a seamless hard bone elbow, which means that it cannot find a single weld seam all over its body. It will not explode from the interface under high pressure and has strong pressure resistance. It can withstand the sulfuric acid/alkali solution in chemical factory pipelines, withstand the steam pressure of high-pressure boilers, and withstand the radiation environment and high temperature and pressure in nuclear power plant pipelines.
Choosing different materials can also achieve different effects: food grade 304 is suitable for pipeline bends in dairy factories, rust proof and hygienic; Thickened 316L is suitable for soaking in seawater for ten years without rusting through, specifically designed for island power stations.
The cost of stainless steel seamless elbows is higher than that of ordinary welded elbows, but it makes sense that they are expensive: they have complex processes, more consumables, can withstand high pressures of 80MPa, and have a lifespan of over 50 years!
