Abrasion-resistant anti-slip heat-insulation combined type flanged pipe fitting

Abstract

The invention relates to a wear-resistant, non-slip and heat-preserving combined flange pipe fitting, which includes a chassis (1) and a pipe body (2). The surface of the chassis (1) is provided with an anti-skid layer, the inner diameter of the pipe body (2) is provided with an internal thread (2.1), and the surface of the internal thread (2.1) is provided with a wear-resistant layer, and the pipe body (2) The outer surface of the pipe body (2) is provided with an insulating layer, and the top end of the outer wall of the pipe body (2) is provided with a flange (3). The wear-resistant, anti-slip and heat-preserving combined flange pipe fitting of the present invention has stronger load-bearing capacity, prolongs the service life, makes assembly or maintenance easier, is not easy to slip by hands, and ensures the temperature in the pipe body well, and the heat is not easy to dissipate. The life of the equipment is extended, the bolts are not easy to 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, anti-skid and thermal insulation 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 being used for a period of time, traditional flanged pipe fittings have poor load-bearing capacity, are easy to break, and have a short service life. During assembly or maintenance, they are easy to slip by hand, which increases the difficulty of assembly or maintenance. 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 purpose of the present invention is to overcome the above disad...
