Icon: the pipe comprises a pipe body 1, a hot melt adhesive coating 2, an anticorrosive plastic layer 3, a connecting flange 4, a flanging 5, a T-shaped head 6, an embedded ring groove 7 and a reinforcing mesh layer 8.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Example 1
Referring to fig. 1 to 2, the present embodiment provides a flange plastic-lined pipe, including a pipe body 1 and connecting flanges 4 disposed at two ends of the pipe body 1, wherein the inner wall of the pipe body 1 is coated with a hot melt adhesive coating layer 2, an anti-corrosion plastic layer 3 is disposed on the surface of the hot melt adhesive coating layer 2, and the anti-corrosion plastic layer 3 and the pipe body 1 are formed by extrusion molding together. The anti-corrosion plastic layer 3 is made of polyethylene materials, a reinforcing net layer 8 is arranged in the pipe body 1 in a hot melting mode, and the reinforcing net layer 8 is integrated with the pipe body 1 in a hot melting mode. Wherein, the thickness of the reinforced net layer 8 is 1-1.5mm, the thickness of the anti-corrosion plastic layer 3 is 1-2 mm, and the thickness of the hot melt adhesive coating layer 2 is 1-1.5 mm.
The both sides tip of anticorrosive plastic layer 3 has the extension section, the extension section is rolled up to connecting flange 4's outer terminal surface one side and is formed turn-ups 5, turn-ups 5's end is T type head 6, connecting flange 4's outer terminal surface is provided with the embedded annular 7 of T type, in the embedded annular 7 of T type head 6 embedding and through the powerful glue adhesion fixed.
It can be known from the above, the pipe is moulded to flange lining that this embodiment provided through set up hot melt adhesive coating 2 as the transition layer between tubular product body 1 inner wall and anticorrosive plastic layer 3, makes the bonding between anticorrosive plastic layer 3 and the pipe fitting firm. Simultaneously, the anti-corrosion plastic layer 3 is turned over 5 towards one side of the outer end face of the connecting flange 4, so that the two connecting flanges 4 are mutually butted, the turned-over 5 passing through the anti-corrosion plastic layer 3 serves as a sealing gasket, self sealing is formed, an external sealing gasket is not needed, and the butt joint between two liner pipes is greatly facilitated.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
