Anti-wear and heat-preservation hub flange pipe fitting

Abstract

The invention relates to an anti-wear and heat-preservation hub flange pipe fitting which comprises a chassis (1) and a pipe body (2), wherein cross sections of the chassis (1) and the pipe body (2) are annular; inner threads (2.1) are disposed on the inner diameter of the pipe body (2); an anti-wear layer is disposed on the surface of the inner threads (2.1); a heat-preservation layer is disposed on the outer surface of the pipe body (2); a reinforcement rib (4) is disposed on the outer wall of the heat-preservation layer; and a flange (3) is disposed on the top end of the outer wall of the pipe body (2). The anti-wear and heat-preservation hub flange pipe fitting provided by the invention has the advantages that temperature in the pipe body is ensured effectively; heat is not emitted easily; the service life of equipment is prolonged; load bearing capacity is enhanced; the service life is prolonged; and after setting of the anti-wear layer on the surface of the inner threads, bolts could be screwed more tightly and will not get separated easily, and the threads on the surface will not get worn after long-time use.

Description

technical field [0001] The invention relates to a flange pipe fitting, in particular to a wear-resistant and heat-preserving flange pipe fitting with a neck. Background technique [0002] Flange fittings are generally installed between equipment and at the junction of pipe body and pipe body. Flange fittings are widely used in mechanical equipment. After a period of use, the traditional flange pipe fittings have poor load-bearing capacity, are easy to break, and have a short service life. The heat of the pipe body will be dissipated. After a long time, the pipe wall is easy to be scalded or frozen, which shortens the service life of the equipment. The threads on the inner surface are easily worn, and the bolts are not tightly bolted. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a wear-resistant and heat-retaining flanged pipe fitting with a neck that is not easy to wear, has a strong load-bearing...
