Description

Technical Field

[0001] The utility model relates to the field of welded pipes, in particular to a welded pipe with detachable closed round caps arranged at both ends. Background Art

[0002] Welded steel pipes, also known as welded tubes, are steel pipes made by welding steel plates or strips after being coiled and formed. The process flow of welded pipes is raw material uncoiling - leveling - end shearing and welding - loop - forming - welding - removal of internal and external welding beads - pre - correction - induction heat treatment - sizing and straightening - eddy current detection - cutting - hydrostatic inspection - pickling - final inspection (strict control) - packaging - shipment. The products are widely used in water supply projects, petrochemical industries, chemical industries, power industries, agricultural irrigation, and urban construction.

[0003] Welded pipes can be used as anti - collision pipes, connecting pipes, and conveying pipes, etc. When traditional welded pipes are used as connecting pipes, they only utilize the characteristics of their straight pipes to connect with structural components. The two ends of the welded pipes are connected to connecting objects and fixed, and the connection parts are mostly fixed by welding. However, when traditional welded pipes are used as connecting pipes, there is a lack of strengthening design at both ends, and the strength of the connection parts determines the service life of the welded pipes. The two ends of the welded pipes need to be strengthened against compression, pressure resistance, and anti - collision. Moreover, due to the hollow structure inside traditional welded pipes, operations such as threading can be carried out, but there is a lack of guidance and safety guidance for wire arrangement at both ends of the welded pipes.

[0004] Therefore, to solve the above problems, the utility model provides a welded pipe with detachable closed round caps arranged at both ends, which can improve the compressive resistance and protection ability of the steel pipe by installing closed round caps inside the inner walls at both ends of the steel pipe body, and can provide flexible opening and closing channel options. Content of the Utility Model

[0005] The main technical problem to be solved by the utility model is to provide a welded pipe with detachable closed round caps arranged at both ends, which can improve the compressive resistance and protection ability of the steel pipe by installing closed round caps inside the inner walls at both ends of the steel pipe body, and can provide flexible opening and closing channel options.

[0006] To solve the above - mentioned technical problem, a technical solution adopted by the utility model is: to provide a welded pipe with detachable closed round caps arranged at both ends, including a welded pipe body. The two ends of the welded pipe body are open - ended and internally connected. A plurality of fixing pieces are fixedly installed at the inner wall positions of the two ends of the welded pipe body. The fixing pieces are combined into a surrounding circular ring and fixed on the inner wall of the welded pipe body. An installation hole is opened in the center of the fixing piece, and a closed round cap is connected and installed on the fixing piece. After the closed round cap is installed, it closes the two sides of the welded pipe body.

[0007] In a preferred embodiment of the present utility model, the fixing piece is fixedly welded on the inner wall of the inner sides of both ends of the welded pipe body, the closed round cover is detachably connected and fixed to the fixing piece by a fastener connecting the mounting hole, and the closed round cover is correspondingly retracted into the welded pipe body.

[0008] In a preferred embodiment of the present utility model, a threaded connection hole is provided in the center of the closed round cover, and a rotary cover is threadedly connected to the threaded connection hole, and the rotary cover is integrally threadedly connected to the closed round cover.

[0009] In a preferred embodiment of the present utility model, a knob or a rotating handle is provided on the outer cover body of the rotary cover.

[0010] The beneficial effects of the present utility model are as follows: The present utility model can improve the compressive resistance and protection ability of the steel pipe by installing closed round covers on the inner sides of both ends of the steel pipe body, and can provide flexible opening and closing channel selection. After the closed round covers are installed, they form pressure-resistant protection for both ends of the steel pipe body, and both ends of the steel pipe body are not easily flattened and deformed. The closed round covers can provide compressive support when the steel pipe body is under pressure. After the closed round covers are installed, the connection between both ends of the welded pipe body can also be opened or closed through the rotary cover. When the rotary cover is opened, it can be used for threading and leading wires inside the welded pipe body and introducing internal components, and when the rotary cover is closed, the closed operation of the welded pipe body is realized.
