The invention relates to an abrasion-resistant heat-insulation grooved-surface flanged pipe fitting used for a small workshop. The abrasion-resistant heat-insulation grooved-surface flanged pipe fitting used for the small workshop comprises a base plate (1) and a pipe body (2). The cross section of the base plate (1) and the cross section of the pipe body (2) are both circular. An internal thread (2.1) is arranged on the inner-diameter portion of the pipe body (2). An abrasion-resistant layer is arranged on the surface of the internal thread (2.1). A heat-insulation layer is arranged on the outer surface of the pipe body (2). A flange (3) is arranged at the top end of the outer wall of the pipe body (2). A groove (4) is formed between the flange (3) and the top of the pipe body (2). According to the abrasion-resistant heat-insulation grooved-surface flanged pipe fitting used for the small workshop, connection between devices and between pipe bodies is firmer, the temperature in the pipe body is well ensured, heat is unlikely to be dissipated, and the life of the devices is prolonged; and after the abrasion-resistant layer is arranged on the surface of the internal thread, a bolt can be screwed more tightly and is not prone to falling, and the thread on the surface is not abraded after long-time use.
