The invention relates to an antiskid insulating abrasion-resistant flat welding type flange pipe fitting for a workshop. The antiskid insulating abrasion-resistant flat welding type flange pipe fitting comprises a chassis (1) and a pipe body (2), wherein cross sections of the chassis (1) and the pipe body (2) are circular ring-shaped; an antiskid layer is arranged on the surface of the chassis (1); an internal thread (2.1) is arranged at the inner diameter of the pipe body (2); an abrasion-resistant layer is arranged on the surface of the internal thread (2.1); an insulating 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); and a non-stick layer is arranged on the surface of the flange (3). According to the antiskid insulating abrasion-resistant flat welding type flange pipe fitting for the workshop, connection among devices and among the pipe bodies is firmer, assembly or maintenance is easier, hands are not liable to slip, temperature in the pipe body is well guaranteed, heat is not liable to dissipate, bolts are not liable to fall off, the surface thread is not abraded after long-time use, dust is not liable to deposit, and cleaning is convenient.
