Abstract:
An anti-abrasion pipe fitting for high speed particle-laden flow, having a curved T-shape, and comprising:a first upstream straight portion; a downstream straight portion extended on the same axis with respect to the first upstream straight portion; a second upstream straight portion formed at a certain angle with respect to the first upstream straight portion and downstream straight portion; an upstream flow direction changing portion formed between the first upstream straight portion and the second upstream straight portion; a downstream flow direction changing portion formed between the second upstream straight portion and the downstream straight portion; and a connection portion connecting the first upstream straight portion and the downstream straight portion, wherein the upstream flow direction changing portion is formed with a standard flow range, and the downstream flow direction changing portion is enlarged to the outside of the standard flow range so as to form a vortex flow field during a fluid feed.
