Stainless steel pipe with enhanced wear resistance

Abstract

This utility model discloses a stainless steel pipe with enhanced wear resistance, relating to the field of stainless steel pipe technology. It includes a first stainless steel pipe and a reinforcing sleeve. The reinforcing sleeve is fixed to one side of the first stainless steel pipe, and a threaded groove is provided on one side of the reinforcing sleeve. A second stainless steel pipe is connected inside the threaded groove. This utility model uses the threaded groove inside the reinforcing sleeve to rotate one end of the second stainless steel pipe into the reinforcing sleeve via connecting threads, thus assembling the first and second stainless steel pipes. Simultaneously, the covering effect of the reinforcing sleeve ensures the sealing of the connection, preventing leakage. Pushing a movable ring to one side of the reinforcing sleeve connects the movable rod to the connecting groove, which is then locked by a fixing bolt. Combined with the support rod, this provides further reinforcement and protection at the interface.

Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe technology, and in particular to a stainless steel pipe with enhanced wear resistance. Background Technology

[0002] Stainless steel pipe is a hollow, long, cylindrical steel material. It is used as a pipeline for transporting fluids and is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, and machinery, as well as mechanical structural components.

[0003] Common stainless steel pipes require extensive welding work when connected, which is not only cumbersome and time-consuming, but also requires a high level of technical skill from the operators. In addition, some existing stainless steel pipes have room for optimization in terms of rapid assembly and reliable reinforcement in certain special scenarios. Therefore, it is necessary to design a stainless steel pipe with enhanced wear resistance. Utility Model Content

[0004] The purpose of this utility model is to provide a stainless steel pipe with enhanced wear resistance to solve the problems of difficult connection and inconvenient reinforcement mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a stainless steel pipe with enhanced wear resistance, comprising a first stainless steel pipe and a reinforcing sleeve, wherein the reinforcing sleeve is fixed on one side of the first stainless steel pipe;

[0006] One side of the reinforcing sleeve is provided with a threaded groove, and a second stainless steel tube is connected inside the threaded groove. The outer side of the second stainless steel tube is provided with a connecting thread, and the connecting thread and the threaded groove are threadedly connected. A connecting sleeve is fixed at the middle position of the reinforcing sleeve, and a connecting groove is evenly provided on one side of the connecting sleeve. A fixing ring is fixed on the outer side of the first stainless steel tube, and a connecting rod is evenly fixed on the inner side of the fixing ring. The inner side of the connecting rod is fixedly connected to the connecting sleeve. A movable ring is movably connected to the outer side of the second stainless steel tube, and a movable rod is evenly fixed on the inner side of the movable ring. The movable rod is provided with a threaded hole inside, and the inside of the threaded hole is threaded with a wear-resistant coating.

[0007] Furthermore, the outer side of the first stainless steel tube is provided with a wear-resistant coating, and the wear-resistant coating is made of ceramic coating material.

[0008] Furthermore, the inner side of the first stainless steel pipe is connected to a wear-resistant and corrosion-resistant inner pipe, and mounting blocks are uniformly fixed on the outer side of the wear-resistant and corrosion-resistant inner pipe. Mounting grooves are uniformly arranged inside the first stainless steel pipe, and the mounting grooves are all connected to the mounting blocks.

[0009] Furthermore, the width of the mounting block matches the width of the mounting slot, and both the mounting block and the mounting slot are provided in six sets.

[0010] Furthermore, the connecting groove is provided in four sets, and the connecting groove is arranged in a cross shape on one side of the connecting sleeve.

[0011] Furthermore, the interior of the reinforcing sleeve is provided with a spiral-shaped slow-flow channel.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the stainless steel pipe with enhanced wear resistance realizes the functions of easy assembly and reinforcement as well as enhanced wear resistance;

[0013] Through the threaded groove inside the reinforcing sleeve, one end of the second stainless steel pipe is rotated into the reinforcing sleeve via the connecting thread, so that the first and second stainless steel pipes are assembled. At the same time, the covering effect of the reinforcing sleeve ensures the sealing of the connection, making it less prone to leakage. Then, the movable ring is pushed to one side of the reinforcing sleeve, so that the movable rod is connected with the connecting groove and locked by the fixing bolt. With the help of the support rod, the interface can be further reinforced and protected, making it less prone to deformation under the influence of external forces, and providing effective support and limit for the steel pipe connection.

[0014] By setting the wear-resistant coating material to a ceramic coating, which has high hardness, good wear resistance, high temperature resistance, and strong chemical stability, and by setting an internal wear-resistant and anti-corrosion inner tube, the wear resistance effect is further enhanced by double protection inside and outside the stainless steel pipe, which greatly improves the protective performance. At the same time, the wear-resistant and anti-corrosion inner tube can be installed, removed and replaced through the installation block and installation groove, thus extending the wear resistance effect of the stainless steel pipe.
