摘要： An anti-abrasion pipe fitting for high speed particle-laden flow is disclosed, which includes a plurality of flow fields such as a vortex flow field formed at a flow direction changing portion during a fluid feed by expanding an outer side curved portion and inner side curved portion of the flow direction changing portion to the outside of a standard flow range in an elbow shaped curved coupling pipe formed of an upper side straight portion, a lower side straight portion perpendicular to the upper side straight portion, and a flow direction changing portion formed between the upper side straight portion and the lower side straight portion, so that it is possible to prevent an abrasion at a portion in which a flow direction is changed without forming a protection film formed of an anti-abrasive material at an inner wall of a pipe for thereby increasing the life span of the system.
