Stainless steel seamless elbows are like the “joints” of the pipeline system, allowing water, oil and gas to run around the factory. Ordinary elbows are like building Lego, which requires welding or screwing, while seamless elbows are like kneading plasticine – directly pressing the stainless steel into a whole piece, and the bends are smooth enough to skate. Stainless steel seamless elbows have several hidden skills: 1. Food factories use mirror-polished elbows, which can be used as mirrors at the bends. 2. The latest elbows have self-cleaning coatings, so breweries don’t need to wash the pipes for half a year without blocking. 3. Nuclear submarine pipelines use thickened elbows, which can still turn flexibly under high pressure in the deep sea.
