Description of the invention: [Technical field to which the invention belongs] TECHNICAL FIELD The present invention relates to, for example, the connection between the proportional control valve and the gas distribution device 5 and becomes a gas passage from the proportional control valve to the gas distribution device: gas connection pipe . C. Prior Art In the past, this type of gas connection piping system used a pipe material having a circular cross section. When the pipe material is used as a connecting pipe, in order to be connected to other equipment such as a proportional control 阙 or a gas distribution device, it is necessary to install connecting devices and the like at both ends. Regarding such a connection structure, for example, a ring-shaped flange portion is provided in the vicinity of the end portion of the pipe material, and the front end portion of the flange portion is inserted into the connection target, and the flange portion is pressed to Many proposals, such as avoiding detachment from a connection target (for example, refer to Patent Literature 1 and Patent Literature 2). [Patent Document 1] Japanese Patent Publication No. 8-17〇765 (Figures 1 to 5) [Patent Literature 2] Japanese Patent Publication No. 8_285161 (Figures 1 to 20 to 5) [Summary of the Invention] Problems to be Solved by the Invention As mentioned above, the conventional gas liaison pipe must be equipped with other parts such as connection equipment at the end of the pipe material. 200540356 As a result, the cost of gas is higher. Further, the type disclosed in Patent Document 2 is a welded pipe material and a connecting device. However, it is necessary to check whether gas leaks from the welded portion, and the productivity of the welding operation cannot be said to be good. 5 13 This is due to the above problems, and an object of the present invention is to provide a gas connection pipe which can be connected to other equipment without using other installation equipment or the like. Means for Solving the Problem In order to solve the above-mentioned problem, the gas contact pipe of the present invention is formed of at least one of a pair of substantially 0 rectangular plates along the length of the foregoing plate, and a continuous recessed portion that becomes a gas passage is formed by sheet metal processing, and The two plates are hermetically merged with each other at the same time. At the same time, a gas flow inlet is opened at one end of the gas passage formed by the aforementioned recessed portion, and a gas flow outlet is opened at the other end. Fifteen people in the present invention did not use pipe material in the part that became the gas passage, but formed a gas connection pipe through a pair of sheet metal and guarding each other. If the structure is adopted, the population of gas and gas outlets will be formed on the board. In this way, the surrounding part of the gas machine inlet or gas flow outlet can play the role of the flange corner 20 or the retaining part of the sealing member without having to install other connection devices. Therefore, the gas flow around the aforementioned gas flow A nucleated section of at least one of the inlet and the gas outlet is formed in a direction recessed from the surface of the aforementioned plate material, and a ring-shaped sealing member is mounted on the section. Another 'right is a pair of plates with a recess formed in only one of the plates, and 200540356 has both a gas flow inlet and a gas flow outlet on the other plate, then the other plate can become flat, gj' Closely connected to the machine to which it is connected. " It is also possible to form the aforementioned recesses on both the pair of plates, and at the same time,
