Problems solved by technology

After a period of use of traditional flanged pipe fittings, the heat of the pipe body will be dissipated. After a long time, the pipe wall will be easily scalded or frozen, which shortens the service life of the equipment. The threads on the inner surface are easily worn, and the bolts cannot be bolted tight

Abstract

The invention relates to a wear-resistant and heat-preserving flange pipe fitting, which includes a chassis (1) and a pipe body (2), the cross sections of the chassis (1) and the pipe body (2) are both ring-shaped, and the pipe body (2) ) is welded to the inner diameter of the chassis (1), the chassis (1) is provided with a large through hole (1.1), the inner diameter of the pipe body (2) is provided with an internal thread (2.1), and the internal thread ( 2.1) A wear-resistant layer is provided on the surface, an insulation layer is provided on the outer surface of the pipe body (2), and a flange (3) is provided on the top of the outer wall of the pipe body (2). The wear-resistant and heat-preserving flange pipe fitting of the present invention can well ensure the temperature in the pipe body, the heat is not easy to dissipate, and the service life of the equipment is prolonged. It will not fall off, and the threads on the surface will not be worn out after long-term 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. 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 of traditional flanged pipe fittings, the heat of the pipe body will be dissipated. After a long time, the pipe wall will be easily scalded or frozen, which shortens the service life of the equipment. The threads on the inner surface are easily worn, and the bolts cannot be bolted tight. 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 flange pipe fitting that is not easy to wear and maintain heat. [0004] The object of the present invention is achieved as follows: a wear-resistant and heat-preserving flange ...
