본 발명은 극저온 액화석유가스용 파이프에서 T형 연결부분의 단열부 클래딩(덮개)에 관한 것으로, The present invention relates to a thermal insulation cladding (cover) of the T-type connection in the cryogenic liquefied petroleum gas pipe,

더 구체적으로는, More specifically,

극저온 액화석유가스용 파이프의 단열부를 암수 대칭으로 형성하여 양쪽에서 덮어 맞닿는 부분을 결합하는 암수로 형성된 단열부 클랜딩에 있어서:In the insulator clanding formed of male and female insulated symmetrical thermal insulation of the pipe for cryogenic liquefied petroleum gas, joining the parts covered by both sides:

T형 연결부분의 수평 파이프 부분을 덮도록 반원통형으로 형성되고 라운딩부재(131,132) 및 묶음결합부재(140)와 결합되는 절단부가 중간 하부에 형성된 수평부재(110);A horizontal member 110 formed in a semi-cylindrical shape so as to cover a horizontal pipe portion of the T-shaped connecting portion, and a cut portion coupled to the rounding members 131 and 132 and the bundle coupling member 140 in a middle lower portion thereof;

T형 연결부분의 수직 파이프 부분을 덮도록 반원통형으로 형성되고 상부에는 라운딩부재(131,132) 및 묶음결합부재(140)와 결합되는 절단부가 형성된 수직부재(120);A vertical member 120 formed in a semi-cylindrical shape so as to cover the vertical pipe portion of the T-shaped connecting portion and having a cut portion coupled to the rounding members 131 and 132 and the bundle coupling member 140;

수평부재(110)와 수직부재(120) 사이를 라운딩 형성되도록 연결하는 라운딩부재(131,132);Rounding members (131, 132) for connecting the horizontal member 110 and the vertical member 120 to form a rounding;

수평부재(110), 수직부재(120) 및 라운딩부재(131,132)가 만나는 부분을 연결하는 묶음결합부재(140) 및;A bundle coupling member 140 connecting a portion where the horizontal member 110, the vertical member 120, and the rounding members 131 and 132 meet;

수평부재(110), 수직부재(120), 라운딩부재(131,132) 및 묶음결합부재(140)의 결합을 위해 겹쳐지는 가장자리에 소정 간격으로 구멍을 형성하고, 구멍에 리벳팅하되 클래딩의 내부리벳머리(152)는 0.1mm 이하 두께로 형성된 리벳(151);으로 이루어지며, 같은 모양의 암수로 형성된 것을 특징으로 하는 암수 극저온 액화석유가스용 파이프에서 T형 연결부분의 단열부 클래딩 및 그 제조방법에 관한 것이다.Holes are formed at predetermined intervals on the overlapping edges for coupling the horizontal member 110, the vertical member 120, the rounding members 131 and 132, and the bundle coupling member 140, and riveted to the holes, but the inner rivet head of the cladding 152 is a rivet 151 formed to a thickness of 0.1mm or less; consisting of a male and female cryogenic liquefied petroleum gas pipe, characterized in that formed in the same shape male and female thermal insulation cladding of the T-type connection portion and a method of manufacturing the same It is about.

액화석유가스(LNG)는 액화온도가 -162℃ 이하로 되기 때문에 선박이나 해저 등에 설치되는 액화석유가스관은 단열이 무엇보다 중요하며, 파이프를 덮고 있는 단열재는 극저온 상태에서는 얼어있는 상태이기 때문에 각진 부분이나 내부로 돌출된 부분은 비록 작은 부분이라 하더라도 클래딩 작업과정이나 지진 또는 파도 등에 의해 내부 단열재를 누르게 되면 파손되거나 크랙 등이 발생하게 되고, 이러한 틈새로 인하여 열이 유입되면 액화석유가스는 폭발적으로 기화 팽창되면서 가스관 폭발 등 으로 이어지곤 하게 된다.Since liquefied petroleum gas (LNG) has a liquefaction temperature of -162 ° C or lower, liquefied petroleum gas pipes installed in ships or seabeds are most important for insulation, and the insulators covering pipes are frozen at cryogenic conditions. However, even if the part protrudes inside, even if it is a small part, when the internal insulation is pressed by the cladding process or the earthquake or the wave, it may be broken or cracked. As it expands, it can lead to gas pipe explosions.

액화석유가스 중에서도 T형 연결부분에서 단열재를 덮는 클래딩은 직각의 각진부분은 취약한 부분으로서 설치과정, 지진, 파도 등에 의해 얼어있는 단열재를 눌러 단열재 사이에 크랙 등을 발생시켜 큰 사고로 이어지는 부분이기도 하였다.Among the liquefied petroleum gas, the cladding covering the insulator in the T-type connection part is weak at right angles, and it is a part that leads to a big accident by pressing cracked insulator by the installation process, earthquake, waves, etc. .

종래 T형 연결부의 클래딩 직각의 각진부분이 내부 단열재 눌림으로써 크랙을 발생시키는 경우가 많았기 때문에, 본 발명은 다수개의 부재를 사용하여 T형 연결부의 각진 부분을 라운딩 형성함으로써 각진 내부에 의해 눌림이 발생하는 것을 구조적으로 원천 방지한 것이다.Since the angular portion of the cladding right angle of the conventional T-shaped connection part often generates cracks by pressing the inner insulation, the present invention uses a plurality of members to form rounded angular portions of the T-type connection part so that the crushed portion is pressed by the angular inside. It is structurally prevented from occurring.

또한 본 발명은 다수개의 부재와 암수 클래딩 연결부분에 결합용으로 사용하는 리벳에서 내부리벳머리를 0.1mm 이하의 두께로 납작하게 형성함으로써 리벳머리가 내부 단열재를 눌리는 것을 방지한 것이다.In addition, the present invention is to prevent the rivet head from pressing the internal insulation by forming a flat inner rivet head to a thickness of 0.1mm or less in the rivet used for coupling to a plurality of members and male and female cladding connection.

이와 같이 본 발명은 영하 162도 이하의 얼어있는 단열재를 눌러 크랙을 발생시킬수 있는 요인을 구조적으로 제거한 것이다.As described above, the present invention structurally eliminates a factor that can cause cracking by pressing a frozen insulating material below minus 162 degrees.

종래기술로서 특허등록 제10-1512589호에 배관의 단열재를 덮는 직각의 암수 클래딩 구조가 공지되어 있다. 클래딩에서 직각의 각진부분은 내부 단열재 구조를 눌러 얼어있는 단열재에 크랙 등을 유발할 수 있었다.As a prior art, patent registration No. 10-1512589 discloses a male and female cladding structure having a right angle covering a heat insulating material of a pipe. Right angles in the cladding could press the internal insulation structure and cause cracks in the frozen insulation.

본 발명의 클래딩은 액화석유가스관 외부에 형성되는 단열재의 외면을 고정하는 함석 등 금속판재로 형성된 덮개이다.Cladding of the present invention is a cover formed of a metal plate, such as a tin to secure the outer surface of the heat insulating material formed on the liquefied petroleum gas pipe.

클래딩 중에서 T형 연결부분의 클래딩은 직각으로 꺽어지기 때문에 내부로 각진 부분이 형성되어 설치과정이나 지진, 파도 등에 의해 흔들리게 되면 각진부분은 얼어있는 상태인 단열재를 눌러 크랙을 유발할 수 있었다.Since the cladding of the T-type connecting part of the cladding is bent at right angles, an angled portion is formed inside, and when the shaking is caused by an installation process, an earthquake or a wave, the angled portion may press the frozen material to induce cracking.

또한 본 발명은 T형 연결부분의 클래딩은 수평부재(110), 수직부재(120), 라운딩부재(131,132) 및 묶음결합부재(140)의 조각을 리벳으로 결합하여 형성하는 과정에서 리벳머리가 내부로 돌출되어 단열재를 눌러 크랙을 유발하는 것을, 내부 리벳머리를 0.1mm이하로 낮게 형성함으로써 둥근 리벳머리에 의한 단열재 눌림을 구조적으로 방지한 것이다.In addition, in the present invention, the cladding of the T-shaped connecting portion has a rivet head inside the horizontal member 110, the vertical member 120, the rounding member (131, 132) and the combination of the pieces of the bundle coupling member 140 formed by rivets. By protruding to press the insulation to cause cracks, by forming the inner rivet head lower than 0.1mm structurally prevented the pressing of the insulation by the round rivet head.

클래딩은 먼저 함석이나 알루미늄판재 등의 금속판재를 펼친 상태의 수평부재(110), 수직부재(120), 라운딩부재(131,132), 묶음부재(140) 모양으로 절단하고, 절단된 부재 중에서 수평부재(110), 수직부재(120), 라운딩부재(131,132)는 금형을 사용하여 소정의 형상을 형성한다. 묶음결합부재는 형상을 형성하지 안더라도 거의 평평한 형태이기 때문에 그대로 결합할 수 있는 것이다.Cladding is first cut into the horizontal member 110, the vertical member 120, the rounding member (131, 132), the bundled member 140 in the state of spreading the metal plate, such as tin or aluminum plate, and the horizontal member ( 110, the vertical member 120, the rounding members (131, 132) to form a predetermined shape using a mold. The bundle coupling member can be combined as it is because it is almost flat even without forming a shape.

각 조각부재는 리벳팅으로 연결하는데, 수평부재(110)와 수직부재(120)의 사이에 라운딩부재를 대칭으로 연결하는데 라운딩부재의 한쪽은 수평부재, 다른쪽은 수직부재를 연결한다.Each piece member is connected by riveting, the symmetrical connection of the rounding member between the horizontal member 110 and the vertical member 120, one side of the rounding member connects the horizontal member, the other side vertical member.

라운딩부재는 종래 T형 연결부분의 각진 부분을 잘라내고 라운딩 하는 것으로 좁은 삼각형 모양을 하며 폭 방향으로는 둥글게 형성하지 않아도 연결하면 큰 구조에서 라운딩을 형성하는 것이다. 물론 라운드 판재를 금형에서 폭 방향으로도 둥글게 형성되도록 하여 사용할 수 있다.The rounding member has a narrow triangular shape by cutting and rounding the angular portion of the conventional T-shaped connecting portion and forms a rounding in a large structure when the rounding member is connected without having to be round in the width direction. Of course, the round plate may be used to be formed round in the width direction in the mold.

수평부재(110), 수직부재(120), 라운딩부재(131,132)의 결합이 끝나면, 라운딩부재(131,132) 끝부분이 만나는 부분에는 묶음결합부재(140)가 결합되는 구멍이 형성되며, 묶음결합부재(140)는 를 수평부재(110), 수직부재(120), 라운딩부재(131,132)를 묶어주는 역할을 하는 것이다.

극저온 단열재는 영하 162도 이하에서는 얼어있기 때문에 조금한 힘이 가해져도 금이 가거나 틈새가 발생하기 쉬우며, 리벳머리와 같이 뾰족하거나 T자형 클래딩의 경우 결합된 직각부분의 각진 부분에 의해 눌림되면 틈새가 발생하기 미세한 틈새로 열이 유입되면 온도가 -162 이상이 되면 기화하여 폭발할수 있게 되는 것이다.Cryogenic insulation is frozen below minus 162 degrees, so cracks and crevices are prone to cracking, even if a little force is applied.In case of riveted heads, or in the case of T-shaped cladding, the crevices are pressed by the angled parts of the combined right angles. If heat is introduced into the micro-gap that occurs, it will evaporate when the temperature is above -162.
