brief introduction
The big and small heads whose center is in a straight line are
called concentric big and small heads. The commonly used forming
process is reduced diameter pressing, expanded diameter pressing or
reduced diameter plus expanded diameter pressing. Stamping can also
be used for reducing pipes of some specifications.
distribution characteristics
(1) The bending moment caused by the area pressure difference between the large and small ends of concentric reducer under the action of internal pressure causes the relative opening of the large end and the relative contraction of the small end;
(2) Under the action of internal pressure, the circumferential stress on the inner surface of the large end on the eccentric side and the outer surface of the middle part on the eccentric side of the eccentric reducer is the largest.
Corrosion resistance
Discrimination
SUS316L stainless steel
The two most commonly used stainless steels 304316 (or corresponding to 1.4308 and 1.4408 of German / European standard), the main difference between 316 and 304 in chemical composition is that 316 contains Mo, and it is generally recognized that 316 has better corrosion resistance and is more corrosion resistant than 304 in high temperature environment. Therefore, in high temperature environment, engineers generally choose 316 parts. But the so-called thing is not absolute. In the environment of concentrated sulfuric acid, never use 316 at any high temperature Or it'll be a big deal. People who study mechanics have all studied threads. I still remember a dark solid lubricant that needs to be applied to prevent threads from biting under high temperature: molybdenum disulfide (MoS2), from which two conclusions can be drawn: first, Mo is indeed a high-temperature resistant material (do you know what crucible gold is melted in? Molybdenum crucible!). 2: Molybdenum easily reacts with high valence sulfur ions to form sulfide. Therefore, no stainless steel is super invincible and corrosion-resistant. In the final analysis, stainless steel is a piece of steel with more impurities (but these impurities are more corrosion-resistant than steel). If it is steel, it can react with other
