Description

Stainless steel pipe joint seam marking structure

This creation is about a "stainless steel pipe joint marking structure", especially a stainless steel pipe with direction recognition function.

It is well known that the use of stainless steel pipes is quite extensive, and the transportation of solvents such as strong acid and alkali is generally done by stainless steel pipes. At present, the conventional stainless steel tube (30) is mostly as shown in the eighth figure. It is mainly formed by bending a stainless steel plate, and then bending and then welding at the butt joint to the stainless steel tube (30). a joint seam (31) is formed thereon, and when the excess solder is removed and the stainless steel tube (30) is formed on the joint seam (31) to form a smooth surface, the stainless steel tube (30) can be horizontally connected. To constitute a fluid line for transporting a solvent (40) such as a strong acid or a strong alkali.

However, the conventional structure as described above still has the following problems in practical applications: (1) the stainless steel tube (30) is not clearly marked on the joint seam (31), so that the user can easily use the stainless steel. The tube (30) is laid in the pipeline in a wrong form in which the joint seam (31) is not facing upward. When the joint seam (31) is not facing upward, the joint of the joint seam (31) is strongly eroded by strong acid and alkali. , so that the stainless steel tube (30) is easy to see the sore hole (32) from the joint (31) (please also look at the figure shown in Figure 8), which will greatly shorten the service life; (2) if it is to The joint (31) is mounted upwards, It is necessary to carefully touch the position of the seam (31), which is too slow and inconvenient.

Therefore, how to develop and improve the shortcomings of the above-mentioned conventional stainless steel tubes is indeed the goal of the relevant industry to develop and research. The creator has in this view, thinking and creating ideas, and designing with years of experience. This work was initiated by a multi-party discussion and trial sample test, and several revisions and improvements.

Conventional stainless steel pipes are not clearly marked on the joints, so that the user can easily lay the stainless steel pipes in the wrong way with the joints not facing upwards. When the joints are not facing upwards, the joints will be greatly improved. The opportunity of strong acid and strong alkali impregnation corrosion, this is the technical problem to be solved.

The present invention provides a stainless steel pipe joint seam marking structure, which is mainly formed by bending a stainless steel plate, and then bending and then welding at the butt joint to form a joint seam on the stainless steel pipe. When the excess solder is removed and the stainless steel tube forms a smooth surface on the joint seam, the stainless steel tube can be horizontally connected to form a fluid pipeline for conveying a solvent such as a strong acid or a strong alkali, and the outer circumference of the stainless steel tube is relatively A marking unit is provided at the joint seam, and the marking unit is provided for inspection, which enables the user to see the position of the joint seam at a glance, and facilitates the stainless steel tube. The assembly is completed in the form of the joint seam facing upward, and the marking unit is provided with a matching structure of a marking line, a character, a pattern or at least a combination of the two, thereby obtaining a stainless steel tube joint seam marking structure.

This creation provides a stainless steel pipe joint seam marking structure, which provides inspection by means of the marking unit, which enables the position of the joint seam to be seen at a glance, so that the stainless steel pipe with the joint seam facing up is the easiest and quickest. The form is successfully completed, and the inspection is provided through the marking unit. The stainless steel tube can be prevented from being misconnected to minimize the chance of the joint being corroded by strong acid and strong alkali solvent. The system can effectively extend the service life of the stainless steel tube. Stainless steel tubes do not need to be replaced, so as to greatly reduce the cost burden.

In order to enable your review committee to have a better understanding and understanding of the purpose, characteristics and efficacy of this creation, please refer to the following figure for a brief description of the example. The detailed description is as follows: First, please go to the first picture to As shown in the third figure, the creation provides a stainless steel pipe joint seam marking structure. The stainless steel pipe (10) is mainly formed by bending a stainless steel plate (1), and then bending and then welding at the butt joint. The crucible is formed with a joint seam (11) on the stainless steel tube (10). When the excess solder is removed and the stainless steel tube (10) is formed on the joint seam (11) to form a smooth surface, the stainless steel tube can be (10) horizontally connected to form a fluid line for transporting a solvent (20) such as a strong acid or a strong alkali, and a stainless steel tube (10) is provided with a marking unit (12) at an outer periphery of the joint (11). Providing inspection by the marking unit (12) enables the user to see the position of the joint seam (11) at a glance, and facilitates the assembly of the stainless steel tube (10) with the joint seam (11) facing upward, and The marking unit (12) is provided with a marking line, a text (also viewed as shown in the sixth figure), a pattern or at least The mating structure by binding those.

With the above structure, when the joint seam (11) faces upward to be at the high position of the stainless steel pipe (10), the weakest joint seam (11) can be prevented from being immersed in a solvent of strong acid and alkali (20). In the middle, causing corrosion, the high-flow fluid piping system can play a certain role (please view it as shown in the fourth figure), let alone the low-flow fluid pipeline (please also see the view from the fifth figure) The creation is provided by the marking unit (12), which allows the position of the seam (11) to be seen at a glance, so that the stainless steel tube (10) can be joined in the simplest and quickest condition. Seam (11) upward shape Successfully complete the connection, provide inspection through the marking unit (12), and avoid the misconnection of the stainless steel tube (10) to minimize the chance of the joint (11) being corroded by strong acid and strong alkali solvent (20). The system can effectively extend the service life of the stainless steel pipe (10), so that the stainless steel pipe (10) does not need to be replaced, so as to greatly reduce the cost burden.

In addition, the above-mentioned marking unit (12) can also be used on the stainless steel tube (10) having the joint flange (13) at both ends (please also view it as shown in the seventh figure), according to which the same effect will be obtained. .

In summary, this creation has indeed achieved a breakthrough structural design, with improved creative content, while at the same time achieving industrial use and progress, and this creation has not been seen in any publication, but also novel, when In accordance with the provisions of the relevant laws and regulations of the Patent Law, a new type of patent application is filed according to law, and the examination authority of the bureau is required to grant legal patent rights.

Only the above-mentioned ones are only preferred embodiments of the present invention, and the scope of the implementation of the creation cannot be limited by them; that is, the equal changes and modifications made by the applicants in accordance with the scope of the patent application for this creation should still belong to the creation.
