The invention relates to a heat preservation and antiskid groove face flange pipe fitting for a small workshop. The heat preservation and antiskid groove face flange pipe fitting comprises a bottom disc (1) and a pipe body (2). The cross section of the bottom disc (1) and the cross section of the pipe body (2) are both annular. An antiskid layer is arranged on the surface of the bottom disc (1). An internal thread (2.1) is arranged on the inner diameter of the pipe body (2). A heat preservation layer is arranged on the outer surface of the pipe body (2). A convex edge (3) is arranged at the top end of the outer wall of the pipe body (2). A groove (4) is formed between the convex edge (3) and the top of the pipe body (2). According to the heat preservation and antiskid groove face flange pipe fitting for the small workshop, connection between devices and connection between pipe bodies are firmer; assembling or maintaining is easier; the pipe body is not prone to sliding off from the hand; the temperature in the pipe body is guaranteed well; heat is not prone to being dissipated; and the service life of the devices is prolonged.
