Problems solved by technology
[0002] Most of the existing straight pipes for concrete transportation are still single-layer straight pipes for concrete transportation, with a service life of about 30,000 cubic meters. They are often worn out and scrapped at the welding part of the inlet flange. At this time, the remaining thickness of other parts of the pipe fittings Thick, here is the short life board
As can be seen from the above, the life of the existing delivery pipe is relatively low

The invention provides a conveying pipe and a manufacturing method thereof. The conveying pipe comprises a flange (30) and a pipe body (10), wherein the flange (30) is provided with a third end (31) and a fourth end (32) which are oppositely arranged as well as a sleeving through hole (33) which penetrates through the third end (31) and the fourth end (32); the pipe body (10) is welded together with the flange (30) and provided with a first end (11) and a second end (12) which are oppositely arranged as well as a material through hole (13) which penetrates through the first end (11) and the second end (12); the conveying pipe is characterized in that the first end (11) is positioned at the weld zone hole wall section of the material through hole (13), and a first anti-wear sleeve (20) is fixed at the first end (11); the material through hole (13) is provided with a first blocking part for blocking the first anti-wear sleeve (20) from moving to the second end (12). Due to the adoption of the technical scheme, the conveying pipe is relatively long in service life.
Description
technical field [0001] The present invention relates to the technical field of conveying pipes, in particular, to a conveying pipe and a method for manufacturing the conveying pipe. Background technique [0002] Most of the existing straight pipes for concrete transportation are still single-layer straight pipes for concrete transportation, with a service life of about 30,000 cubic meters. They are often worn out and scrapped at the welding part of the inlet flange. At this time, the remaining thickness of other parts of the pipe fittings It is thicker, and here is a short board for life. It can be seen from the above that the service life of the existing delivery pipe is relatively low. Contents of the invention [0003] The present invention aims to provide a conveying pipe with a longer service life and a manufacturing method of the conveying pipe. [0004] In order to achieve the above object, according to one aspect of the present invention, a delivery pipe is provi...
