Wear-resistant thermal-insulation anti-skid combined type flange pipe fitting

Abstract

The invention relates to a wear-resistant thermal-insulation anti-skid combined type flange pipe fitting. The flange pipe fitting 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 in a circular ring shape, an anti-skid layer is arranged on the surface of the base plate (1), internal threads (2.1) are arranged on the inner diameter surface of the pipe body (2), a wear-resistant layer is arranged on the surface of the internal threads (2.1), a thermal-insulation layer is arranged on the outer surface of the pipe body (2), and a flange (3) is arranged at the top end of the outer wall of the pipe body(2). The wear-resistant thermal-insulation anti-skip combined type flange pipe fitting enables connection between equipment and between pipes to be firmer, makes the assembly or maintenance easier, and is not prone to slide, the temperature in the pipe body can be well guaranteed, the heat is not prone to dissipate, a bolt is not prone to fall off, and the threads on the surface cannot be worn after long-time use.

Description

technical field [0001] The invention relates to a flange pipe fitting, in particular to a wear-resistant, heat-preserving and anti-slip combined 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 the traditional flange fittings are used for a period of time, the economical connection of the equipment or the pipe body is not firm and easy to loosen. During assembly or maintenance, it is easy to slip by hand, which increases the difficulty of assembly or maintenance, and the heat of the pipe body will be dissipated. Finally, the pipe wall is easily scalded or frozen, which shortens the service life of the equipment, and the threads on the inner surface are easily worn, so that the bolts are not tightly bolted. Contents of the invention [0003] The object of the present invention is to overcome the above dis...

After the traditional flange fittings are used for a period of time, the economical connection of the equipment or the pipe body is not firm and easy to loosen. During assembly or maintenance, it is easy to slip by hand, which increases the difficulty of assembly or maintenance, and the heat of the pipe body will be dissipated. After that, the pipe wall is easily scalded or frozen, which shortens the service life of the equipment, and the threads on the inner surface are easily worn, so that the bolts are not tight.
