Description
본 발명은 압력배관의 보수 및 모니터링 방법에 관한 것으로서, 보다 상세하게는 압력배관의 누설부위를 효과적으로 밀봉시킴과 함께 압력배관의 내부압력에 의해 보수구조물의 접착강도가 저하되는 것을 방지할 수 있으며, 보수 후 압력배관의 누설 여부를 실시간으로 확인함과 함께 누설 여부에 따라 압력배관의 압력을 선택적으로 제어할 수 있는 압력배관의 보수 및 모니터링 방법에 관한 것이다. The present invention relates to a method for repairing and monitoring pressure piping. More specifically, it can effectively seal leakage areas of pressure piping and prevent the adhesive strength of the repair structure from being lowered due to the internal pressure of the pressure piping, This relates to a repair and monitoring method for pressure piping that can check in real time whether there is a leak in the pressure piping after repair and selectively control the pressure of the pressure piping depending on whether there is a leak.
선박 내에는 다양한 유체를 이송하기 위한 압력배관이 구비된다. 예를 들어, LNG, LPG, 중유 등의 연료는 일정 압력으로 이송되는 바, 해당 압력을 견딜 수 있는 압력배관 내에서 이송되어야 한다. 이러한 압력배관에 손상이 발생되어 연료가 누출되는 경우, 압력배관의 손상부위에 대한 보수가 즉각 진행되어야 한다. Pressure piping is provided within the ship to transport various fluids. For example, fuels such as LNG, LPG, and heavy oil are transported at a certain pressure, so they must be transported within a pressure pipe that can withstand that pressure. If damage occurs to such pressure piping and fuel leaks, repairs to the damaged part of the pressure piping must be carried out immediately.
통상, 압력배관 등의 배관류 보수에는 용접을 이용한 보수가 안정성 측면에서 가장 바람직하나, 연료가 이송되는 압력배관의 경우 화재 및 폭발 가능성으로 인해 용접 등의 화기를 이용한 보수방법은 회피된다. Normally, when repairing pipes such as pressure pipes, repair using welding is most desirable in terms of safety, but in the case of pressure pipes through which fuel is transported, repair methods using firearms such as welding are avoided due to the possibility of fire and explosion.
종래의 경우, 화기 보수를 대체하여 접착제, 테이프, 금속패드 등을 이용하는 비화기 보수방법을 이용하고 있다. 구체적으로, 압력배관의 손상 부위에 접착제를 도포하거나, 테이프 등으로 압력배관의 손상 부위를 막은 후 그 위에 접착제를 도포하거나 또는 접착제 도포 후 금속패드를 고정시키는 방식으로 보수를 진행해 왔다. In the conventional case, non-firearm repair methods using adhesives, tapes, metal pads, etc. are used instead of fire repairs. Specifically, repairs have been carried out by applying adhesive to the damaged part of the pressure pipe, blocking the damaged part of the pressure pipe with tape, etc. and then applying adhesive on it, or fixing the metal pad after applying the adhesive.
그러나, 접착제만을 이용하는 경우 접합강도 향상을 위해 넓은 접합면적이 요구되는 단점이 있고, 테이프는 접착제와의 결합력이 약한 문제점이 있으며, 접착제 도포 후 금속패드를 고정시키는 방식은 압력배관의 내부압력이 금속패드의 접합면을 따라 작용하여 접착면에 결함이 형성될 수 있다는 문제점이 있다. However, when using only adhesive, there is a disadvantage that a large bonding area is required to improve bonding strength, tape has a problem of weak bonding strength with the adhesive, and the method of fixing the metal pad after applying the adhesive has the disadvantage that the internal pressure of the pressure pipe is There is a problem that defects may be formed on the adhesive surface by acting along the bonding surface of the pad.
또한, 종래의 비화기 보수방법은 보수작업에 초점이 맞추어져 있어 해당 보수 부위에서의 압력강하가 재차 발생되는지에 대해서는 실시간 모니터링이 가능하지 않은 문제점이 있다. In addition, the conventional boiler repair method focuses on repair work, so there is a problem in that it is not possible to monitor in real time whether the pressure drop at the repair area occurs again.
본 발명은 상기와 같은 문제점을 해결하기 위해 안출한 것으로서, 압력배관의 누설부위를 접착제를 이용하여 효과적으로 밀봉시킴과 함께 압력배관의 내부압력에 의해 접착제의 경화 전 접착면에 결함이 형성되어 접착강도가 저하되는 것을 방지할 수 있는 압력배관의 보수 및 모니터링 방법을 제공하는데 그 목적이 있다. The present invention was devised to solve the above problems. It effectively seals the leakage area of the pressure pipe using an adhesive, and defects are formed on the adhesive surface before curing of the adhesive due to the internal pressure of the pressure pipe, thereby reducing the adhesive strength. The purpose is to provide a repair and monitoring method for pressure pipes that can prevent deterioration.
또한, 본 발명은 보수 후 압력배관의 누설 여부를 실시간으로 확인함과 함께 누설 여부에 따라 압력배관의 압력을 선택적으로 제어할 수 있는 압력배관의 보수 및 모니터링 방법을 제공하는데 또 다른 목적이 있다. Another object of the present invention is to provide a repair and monitoring method for pressure pipes that can check in real time whether the pressure pipes leak after repair and selectively control the pressure of the pressure pipes depending on whether there are leaks.
상기의 목적을 달성하기 위한 본 발명에 따른 압력배관의 보수 및 모니터링 방법은 누설부위가 존재하는 압력배관에 대응되는 곡률을 갖음과 함께 일 영역에 보수용 금속곡판을 관통하는 개구공이 구비된 보수용 금속곡판을 준비하는 단계; 보수용 금속곡판의 일면에 접착제를 도포하는 단계; 누설부위가 존재하는 압력배관에 접착제가 접하도록 보수용 금속곡판을 압력배관에 밀착하여 접착시키는 단계; 및 압력배관의 누설부위에 대응되는 위치에 구비된 보수용 금속곡판의 개구공에 밀봉부재와 압력측정장치로 구성되는 밀봉 겸용 압력측정장치를 개구공이 밀봉되도록 장착하는 단계;를 포함하여 이루어지는 것을 특징으로 한다. The repair and monitoring method of a pressure pipe according to the present invention for achieving the above object is a repair pipe having a curvature corresponding to the pressure pipe where a leak exists and an opening hole penetrating a metal curved plate for repair in one area. Preparing a metal curved plate; Applying adhesive to one surface of a metal curved plate for repair; A step of adhering a repair metal curved plate into close contact with the pressure pipe so that the adhesive is in contact with the pressure pipe where a leak exists; And a step of mounting a sealing pressure measuring device consisting of a sealing member and a pressure measuring device to an opening of a repair metal curved plate provided at a position corresponding to a leakage part of the pressure pipe so that the opening is sealed. Do it as
상기 개구공은, 누설부위가 존재하는 압력배관에 접착제가 접하도록 보수용 금속곡판을 압력배관에 밀착하여 접착시키는 단계;에서, 보수용 금속곡판이 누설부위가 존재하는 압력배관에 밀착된 상태에서 압력배관의 내부압력이 누설부위를 통해 배출될 때 해당 내부압력이 보수용 금속곡판의 밀착면을 따라 이동되지 않고 개구공을 통해 배출되도록 유도한다. In the step of adhering the repair metal curved plate to the pressure pipe so that the adhesive comes into contact with the pressure pipe where the leak is present, the opening hole is formed in a state where the repair metal curved plate is in close contact with the pressure pipe where the leak is. When the internal pressure of the pressure pipe is discharged through the leakage area, the internal pressure is induced to be discharged through the opening hole rather than moving along the contact surface of the metal curved plate for repair.
상기 압력측정장치는 압력배관의 압력을 실시간 측정하며, 측정된 압력배관의 압력 값은 통신모듈을 통해 압력배관 제어장치로 전송되며, 압력배관 제어장치는 압력측정장치에 의해 측정된 압력 값이 미리 설정된 기준압력보다 낮으면 압력배관을 통해 이동되는 유체의 흐름을 차단함과 함께 압력측정장치의 일측에 구비된 알람장치를 통해 알람이 발생되도록 한다. The pressure measuring device measures the pressure of the pressure pipe in real time, and the measured pressure value of the pressure pipe is transmitted to the pressure pipe control device through a communication module. The pressure pipe control device measures the pressure value measured by the pressure measuring device in advance. If the pressure is lower than the set standard pressure, the flow of fluid moving through the pressure pipe is blocked and an alarm is generated through an alarm device provided on one side of the pressure measuring device.
본 발명에 따른 압력배관의 보수 및 모니터링 방법은 다음과 같은 효과가 있다. The method for repairing and monitoring pressure pipes according to the present invention has the following effects.
용접 등을 사용하지 않는 비화기 보수방법을 통해 압력배관의 누설부위를 보수함에 있어서, 누설부위를 효과적으로 밀봉시킴과 함께 내부 압력으로 인해 접착제 경화 전 결함이 형성되는 것을 방지하여 보수구조물의 안정성을 향상시킬 수 있으며, 보수된 압력배관의 압력을 지속적으로 모니터링함과 함께 누설여부에 따라 압력배관을 제어할 수 있어 압력배관의 유지보수를 용이하게 관리할 수 있게 된다. When repairing leakage parts of pressure pipes through non-fired repair methods that do not use welding, etc., the leakage parts are effectively sealed and the stability of the repair structure is improved by preventing defects from forming before the adhesive hardens due to internal pressure. It is possible to continuously monitor the pressure of the repaired pressure piping and control the pressure piping according to whether there is a leak, making it possible to easily manage the maintenance of the pressure piping.

본 발명은 용접 등의 화기를 이용하지 않는 비화기 보수방법을 이용하여 압력배관의 누설부위를 보수함에 있어서, 누설부위를 효과적으로 밀봉시킴과 함께 내부 압력으로 인해 접착제 경화 전 결함이 형성되는 것을 방지하여 보수구조물의 안정성을 향상시킴과 함께 보수된 압력배관의 누설여부를 실시간으로 모니터링하고 그에 따라 압력배관의 압력을 제어할 수 있는 기술을 제시한다. In the present invention, when repairing a leaking part of a pressure pipe using a non-fired repair method that does not use fire such as welding, it effectively seals the leaking part and prevents defects from forming before the adhesive cures due to internal pressure. In addition to improving the stability of repair structures, we present a technology that monitors leaks in repaired pressure pipes in real time and controls the pressure of the pressure pipes accordingly.
앞서 '발명의 배경이 되는 기술'에서 언급한 바와 같이, 종래의 비화기 보수방법은 단순구조로 인해 밀봉특성이 저하됨과 함께 압력배관의 내부압력에 의해 접착강도가 떨어지는 문제점이 있으며, 보수된 압력배관의 누설여부에 대한 모니터링은 구현되지 않은 상황이다. As previously mentioned in 'Background Technology of the Invention', the conventional boiler repair method has a problem in that the sealing characteristics are deteriorated due to the simple structure and the adhesive strength is reduced due to the internal pressure of the pressure pipe, and the repaired pressure Monitoring for leaks in pipes has not been implemented.
이하, 도면을 참조하여 본 발명의 일 실시예에 따른 압력배관의 보수 및 모니터링 방법을 상세히 설명하기로 한다. Hereinafter, a method for repairing and monitoring a pressure pipe according to an embodiment of the present invention will be described in detail with reference to the drawings.
도 1 및 도 2를 참조하면, 누설부위(1a)가 존재하는 압력배관(1)에 대응되는 곡률을 갖는 보수용 금속곡판(11)을 준비한다(S101). 보수용 금속곡판(11)은 압력배관(1)의 누설부위(1a)를 충분히 덮을 정도의 면적을 갖는다. 예를 들어, 보수용 금속곡판(11)은 누설부위(1a)의 면적 대비 5∼20배의 면적을 갖는다. Referring to Figures 1 and 2, a repair metal curved plate 11 having a curvature corresponding to the pressure pipe 1 where the leakage area 1a exists is prepared (S101). The repair metal curved plate 11 has an area large enough to sufficiently cover the leakage portion 1a of the pressure pipe 1. For example, the repair metal curved plate 11 has an area 5 to 20 times larger than the area of the leakage area 1a.
또한, 보수용 금속곡판(11)의 일 영역에는 보수용 금속곡판(11)을 관통하는 개구공이 구비된다. 상기 개구공은, 보수용 금속곡판(11)이 누설부위(1a)가 존재하는 압력배관(1)에 밀착된 상태에서 압력배관(1)의 내부압력이 누설부위(1a)를 통해 배출될 때 해당 내부압력이 보수용 금속곡판(11)의 밀착면을 따라 이동되지 않고 개구공을 통해 배출되도록 유도하는 역할을 한다. 보수용 금속곡판(11)에 개구공이 구비되지 않은 상태에서 압력배관(1)에 밀착되면 압력배관(1)의 누설부위(1a)를 통해 배출되는 내부압력은 보수용 금속곡판(11)과 압력배관(1)을 밀착면을 따라 이동하게 되어 보수용 금속곡판(11)과 압력배관(1) 사이에 구비되는 접착제(12)가 경화되기 전에 접착 면에 결함을 형성하여 접착강도를 약화시키게 된다. 따라서, 보수용 금속곡판(11)에 개구공이 구비됨에 따라 보수용 금속곡판(11)과 압력배관(1) 사이의 접착강도는 압력배관(1) 내부압력의 영향을 거의 받지 않게 된다. In addition, an opening hole penetrating the curved metal plate 11 for repair is provided in one area of the curved metal plate 11 for repair. The opening hole is formed when the repair metal curved plate 11 is in close contact with the pressure pipe 1 where the leakage portion 1a exists and the internal pressure of the pressure pipe 1 is discharged through the leakage portion 1a. It serves to induce the internal pressure to be discharged through the opening hole rather than moving along the contact surface of the repair metal curved plate 11. When the repair metal curved plate (11) is not provided with an opening and is in close contact with the pressure pipe (1), the internal pressure discharged through the leakage portion (1a) of the pressure pipe (1) is connected to the repair metal curve plate (11) and the pressure. As the pipe (1) moves along the contact surface, defects are formed on the adhesive surface before the adhesive (12) provided between the repair metal curved plate (11) and the pressure pipe (1) hardens, thereby weakening the adhesive strength. . Therefore, as the repair metal curved plate 11 is provided with an opening, the adhesive strength between the repair metal curved plate 11 and the pressure pipe 1 is hardly affected by the internal pressure of the pressure pipe 1.
개구공을 구비한 보수용 금속곡판(11)이 준비된 상태에서, 보수용 금속곡판(11)의 일면 즉, 압력배관(1)에 밀착될 보수용 금속곡판(11)의 일면에 접착제(12)를 고르게 도포한다(S102). 이 때, 접착제(12)는 페이스트 형태의 접착제(12) 또는 액상형의 접착제(12)를 이용할 수 있다. In a state where the repair metal curved plate 11 with an opening is prepared, adhesive 12 is applied to one side of the repair metal curved plate 11, that is, to one side of the repair metal curved plate 11 to be in close contact with the pressure pipe (1). Apply evenly (S102). At this time, the adhesive 12 may be a paste-type adhesive 12 or a liquid-type adhesive 12.
이어, 접착제(12)가 도포된 보수용 금속곡판(11)을 누설부위(1a)가 존재하는 압력배관(1) 상에 밀착하여 접착시킨다(S103). 이 때, 보수용 금속곡판(11)의 개구공이 압력배관(1)의 누설부위(1a)에 대응되도록 보수용 금속곡판(11)을 압력배관(1)에 밀착시키며, 그 이유는 상술한 바와 같이 압력배관(1)의 내부압력이 보수용 금속곡판(11)의 개구공을 통해 배출되도록 유도하기 위함이며, 이를 통해 압력배관(1)의 내부압력이 보수용 금속곡판(11)과 압력배관(1) 사이의 밀착면에 작용하는 것을 최소화할 수 있다. Next, the repair metal curved plate 11 coated with the adhesive 12 is adhered in close contact with the pressure pipe 1 where the leakage portion 1a exists (S103). At this time, the repair metal curved plate 11 is brought into close contact with the pressure pipe 1 so that the opening of the repair metal curved plate 11 corresponds to the leakage portion 1a of the pressure pipe 1, and the reason for this is as described above. Likewise, the purpose is to induce the internal pressure of the pressure pipe (1) to be discharged through the opening hole of the metal curved plate (11) for repair, and through this, the internal pressure of the pressure pipe (1) is increased through the metal curved plate (11) for repair and the pressure pipe. (1) The effect on the contact surface between the two can be minimized.
이와 같은 상태에서, 상기 보수용 금속곡판(11)의 개구공에 밀봉 겸용 압력측정장치(13)를 장착시킨다(S104). 상기 밀봉 겸용 압력측정장치(13)은 일 실시예로 일체형을 이루는 밀봉부재(13a)와 압력측정장치(13b)로 구성되며, 압력측정장치(13b)의 일단측에 밀봉부재(13a)가 구비되는 형태 또는 밀봉부재(13a)의 일단측에 압력측정장치(13b)가 구비되는 형태를 이룬다. In this state, the sealing pressure measuring device 13 is installed in the opening of the repair metal curved plate 11 (S104). In one embodiment, the sealing combined pressure measuring device 13 is composed of an integrated sealing member 13a and a pressure measuring device 13b, and the sealing member 13a is provided on one end of the pressure measuring device 13b. or a form in which a pressure measuring device (13b) is provided on one end of the sealing member (13a).
밀봉부재(13a)는 보수용 금속곡판(11)의 개구공을 밀봉하는 형태로 개구공에 끼워지며, 일 실시예로 밀봉부재(13a)의 외면에 나사선이 가공되어 있어 밀봉부재(13a)와 개구공은 나사결합될 수 있다. 또한, 밀봉 상태를 강화시키기 위해 밀봉부재(13a)와 개구공 사이에 와셔 또는 밀봉용 테이프가 구비될 수 있다. The sealing member 13a is inserted into the opening hole of the repair metal curved plate 11, and in one embodiment, a thread is processed on the outer surface of the sealing member 13a, so that the sealing member 13a and the sealing member 13a are formed. The opening can be screwed. Additionally, a washer or sealing tape may be provided between the sealing member 13a and the opening hole to strengthen the sealing condition.
