Description

Technical Field

[0001] This utility model relates to the field of pipe manufacturing equipment technology, specifically to a processing device for stainless steel lined pipes. Background Technology

[0002] Stainless steel lined pipes are made by cladding thin-walled stainless steel pipes on the inner wall of steel pipes. This type of bimetallic steel pipe greatly improves the corrosion resistance of steel pipes in the process of transporting water, hot water, coal gas, natural gas and oil. It has a smooth surface and low fluid resistance, and overcomes the defects of galvanized steel pipes that are prone to corrosion and plastic pipes that are prone to leakage and aging when connected by hot melt. It is an ideal product for upgrading and replacing steel pipes for gas, water and oil transportation.

[0003] The production process of stainless steel lined composite steel pipes requires the stainless steel cylindrical inner liner pipe to be assembled with the carbon steel outer base pipe. Then, the inner and outer pipes are bonded together by hydraulic means. Currently, the inner and outer pipes are assembled manually. Before assembly, the cleaning of the outer surface of the stainless steel pipe (inner liner pipe) is often neglected. Compared with the inner surface of the carbon steel pipe (outer pipe), it is more prone to dust and other impurities, which affect the bonding strength and uniformity between the carbon steel pipe and the stainless steel liner.

[0004] This case arose in order to resolve the aforementioned issues. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The purpose of this utility model is to provide a processing device for stainless steel lined pipes to solve the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a stainless steel pipe processing device, including a base, on which a plurality of placement racks for placing carbon steel pipes are provided, and at one end of the base a plurality of dust sweeping racks are provided, the dust sweeping racks are hollowed out near the upper end, and a plurality of soft rubber blocks are provided in the hollowed-out area, the soft rubber blocks are fixed on the inner wall of the hollowed-out area, and the top of the soft rubber blocks is provided with a dust sweeping brush.

[0009] Preferably, a blower mechanism is provided between the placement rack and the dust sweeper. The blower mechanism is located inside the base and includes an air outlet, which is located on the surface of the base.

[0010] Preferably, the length of the soft rubber block is less than the distance between several dust sweepers.

[0011] Preferably, the soft rubber blocks on the plurality of dust sweepers are arranged in an alternating array.

[0012] Preferably, the base and the placement rack are interconnected and grounded.

[0013] (III) Beneficial Effects

[0014] After adopting the above technical solution, this utility model has the following advantages compared with the prior art: The stainless steel pipe processing device of this utility model sets up a dust sweeping frame in front of the placement frame. When the stainless steel pipe is inserted into the carbon steel pipe, the stainless steel pipe first passes through several dust sweeping frames. The dust sweeping brush on the dust sweeping frame sweeps away the dust and other impurities on the surface of the stainless steel pipe. In order to prevent the static electricity generated during the sweeping process from re-adsorbing dust, the device is grounded to effectively remove static electricity and prevent the re-adsorption of dust and impurities, so that the carbon steel pipe and stainless steel pipe have better bonding strength and uniformity in the subsequent hydraulic composite process.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] This utility model provides a processing device for stainless steel lined pipes, such as... Figure 1-2 As shown, it includes a base 1, on which are provided several racks 2 for placing carbon steel pipes. At one end of the base 1 are several dust sweeping racks 3. The dust sweeping racks 3 are hollowed out near the upper end, and several soft rubber blocks 4 are provided in the hollowed-out area. The soft rubber blocks 4 are fixed on the inner wall of the hollowed-out area, and a dust sweeping brush 5 is provided on the top of the soft rubber blocks 4.

[0020] By setting up a dust sweeping frame 3 in front of the placement frame 2, when the stainless steel pipe is inserted into the carbon steel pipe, the stainless steel pipe first passes through several dust sweeping frames 3. The dust sweeping brush 5 on the dust sweeping frame 3 sweeps away the dust and other impurities on the surface of the stainless steel pipe. In order to prevent the static electricity generated during the sweeping process from re-adsorbing dust, the device is grounded to effectively remove static electricity and prevent the re-adsorption of dust and impurities, so that the carbon steel pipe and stainless steel pipe have better bonding strength and uniformity in the subsequent hydraulic composite process.

[0021] Reference Appendix Figure 1 A blower mechanism is provided between the placement rack 2 and the dust sweeping rack 3. The blower mechanism is located inside the base 1 and includes an air outlet 6. The air outlet 6 of the blower mechanism is located on the surface of the base 1. The blower mechanism blows away the dust and other impurities that have been swept away in a timely manner.

[0022] The length of the soft rubber block 4 is less than the distance between several dust sweeping racks 3. The soft rubber blocks 4 on several dust sweeping racks 3 are arranged in an array that is staggered and inconsistent, so as to ensure that the surface of the stainless steel pipe can be swept to achieve the best effect of removing impurities.

[0023] The base 1 and the placement rack 2 are interconnected and grounded. Grounding the device effectively removes static electricity and prevents the re-adsorption of dust and impurities, resulting in better bonding strength and uniformity between the carbon steel pipe and the stainless steel pipe in the subsequent hydraulic composite process.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
