Description

파이프 보온재 {a pipe lagging material}Pipe lagging {a pipe lagging material}

본 발명은 파이프 보온재에 관한 것으로서, 보다 상세하게는 파이프의 보온 및 단열을 위하여 파이프 외관을 감싸는 보온재의 보온 및 단열 효과를 상승시킬 수 있는 파이프 보온재에 관한 것이다.The present invention relates to a pipe heat insulating material, and more particularly, to a pipe heat insulating material that can increase the heat insulating and heat insulating effect of the heat insulating material surrounding the pipe exterior for heat insulating and heat insulating of the pipe.

일반적으로, 파이프 보온재는 건물이나 지면 등 외부로 노출되는 파이프의 동파나 열손실을 막기 위해 배관 외부에 발포폼 예를 들면 고무(NBR,EPDM등), 폴리에틸렌(가교 발포 PE, 무가교 발포 PE등), 폴리프로필렌(가교발포PP, 무가교발포PP등)등의 발포폼을 씌우고, 이 외부에 테이프를 감아 고정시키고 있다.     Generally, the pipe insulation is foamed outside the pipe to prevent freezing and heat loss of the pipe exposed to the outside of buildings and the ground, such as rubber (NBR, EPDM, etc.), polyethylene (crosslinked foamed PE, non-crosslinked foamed PE, etc.). ), Polypropylene (crosslinked foamed PP, noncrosslinked foamed PP, etc.) is covered with a tape, and the tape is fixed to the outside.

이때 보온재를 파이프 외부에 씌우는 과정을 설명하면, 도 1에서와 같이, 발포폼으로 성형된 바디(1)의 일측을 작업자가 커터칼(미도시)을 통해 수직으로 절개하여 절개면(2)을 형성하고, 절개된 부위를 즉, 절개면(2)을 중심으로 바디(1)를 벌린 상태로 파이프 외주면에 씌운 상태에서 절개된 부위가 벌어지지 않도록 테이프를 감아 고정시키는 것이다.    In this case, the process of covering the insulation to the outside of the pipe, as shown in Figure 1, the operator cuts one side of the body (1) formed of foam foam vertically through a cutter knife (not shown) to cut the incision surface (2) It forms and cuts the tape so that the cut-out part does not open in the state where the cut-out part is covered with the pipe outer peripheral surface with the body 1 open about the cut-out surface 2.

그러나 이와 같은 종래 파이프 보온재에 있어서는, 발포폼 즉, 바디(1) 자체의 외, 내경이 정밀하지 않는 것이기 때문에 테이프를 감아 고정시킨 상태에서 외부 요건에 의해 테이프가 손상되거나 풀릴 우려가 야기되고, 이에 의해서는 절개면(2)이 벌어지게 되어 이 벌어진 틈으로 결로나 열손실 등이 발생되는 문제점이 야기된다.    However, in such a conventional pipe insulation material, since the inner diameter of the foam foam, i.e., the body 1 itself, is not precise, the tape may be damaged or released due to external requirements while the tape is wound and fixed. By this, the incision surface 2 is opened, which causes a problem that condensation or heat loss occurs in the gap.

상술한 문제점을 해소하기 위한 본 발명의 목적은 발포폼 즉, 바디의 절단면이 테이팅 처리후 벌어지는 것을 미연에 방지하여 보온재의 주 목적인 보온 및 단열의 효과가 떨어지는 문제점을 미연에 방지할 수 있는 파이프 보온재를 제공함에 있다.An object of the present invention for solving the above problems is to prevent the foam foam, that is, the cutting surface of the body to be opened after the treatment process in advance to prevent the problem that the effect of the insulation and thermal insulation, which is the main purpose of the thermal insulation material, in advance In providing insulation.

이와 같은 목적을 달성하기 위한 본 발명에 따른 파이프 보온재는, 발포폼으로 성형되며, 외측으로 벌려 파이프 외관을 감싸도록 절단면이 형성되고, 원통형 단면 형상을 갖는 바디를 갖는 파이프 보온재에 있어서, 상기 바디의 절단면은 내부에 히터가 내장되고, 외측에 히터에 의해 가열되는 커터로 이루어진 지그에 의해 절단되는 것을 그 특징으로 한다.     Pipe insulation according to the present invention for achieving the above object is formed in a foam, the cutting surface is formed to surround the pipe appearance spread outwards, pipe insulation having a body having a cylindrical cross-sectional shape, the body of the The cutting surface is characterized in that the heater is built in, and is cut by a jig made of a cutter that is heated by the heater on the outside.

본 발명의 상기 지그에 의해 절단된 바디의 절단면은, 에어 냉각장치에 의해 냉각처리되는 것에 특징이 있다.     The cut surface of the body cut by the jig of the present invention is characterized by being cooled by an air cooling apparatus.

본 발명의 상기 바디의 절단면은 소정각도 경사진 경사면을 이루며, 상기 지그의 커터의 컷팅면은 바디의 절단면과 동일한 경사면을 이루는 것에 특징이 있다.     The cutting surface of the body of the present invention forms an inclined surface inclined at a predetermined angle, and the cutting surface of the cutter of the jig forms the same inclined surface as the cutting surface of the body.

본 발명의 상기 바디의 절단면은 적어도 2면 이상의 경사면을 이루며, 상기 지그의 커터의 컷팅면은 바디의 절단면과 동일한 2면 이상의 경사면을 이루는 것에 특징이 있다.    The cutting surface of the body of the present invention forms at least two or more inclined surfaces, and the cutting surface of the cutter of the jig is characterized by forming two or more inclined surfaces identical to the cutting surface of the body.

본 발명의 상기 바디의 절단면은 사각 또는 원형 또는 삼각 형상의 요철 형상을 이루며, 상기 지그의 커터의 컷팅면은 바디의 절단면과 동일한 사각 또는 원형 또는 삼각 형상의 요철 형상을 이루는 것에 특징이 있다.The cutting surface of the body of the present invention forms a concave-convex shape of a square or a circular or triangular shape, the cutting surface of the cutter of the jig is characterized by forming a concave-convex shape of the same square or circular or triangular shape as the cutting surface of the body.

상술한 본 발명에 따른 특징으로 인해 기대되는 효과로는, 절단면의 형상이 수직으로 형성되는 것이 아니라 접촉면이 우수한 하나 이상 복수의 경사면 또는 요철 형상으로 이루어진 것이기 때문에 바디의 내,외경이 불균일하여도 테이핑 처리후 테이핑이 분리되어도 절단면상에 틈새가 발생되지 않는다.     As expected effects due to the above-described features of the present invention, the shape of the cutting surface is not formed vertically, but because the contact surface is formed of one or more plural inclined surfaces or irregularities, the taping is performed even if the inner and outer diameters of the body are uneven. Even if the tape is separated after the treatment, there is no gap on the cut surface.

따라서 보호재 고유의 목적인 단열 및 보온의 효과가 떨어지는 것을 미연에 방지할 수 있는 효과가 있다.Therefore, there is an effect that can be prevented in advance that the effect of the insulation and thermal insulation inherent purpose of the protective material.

본 발명의 상술한 목적과 여러 가지 장점은 이 기술 분야에 숙련된 사람들에 의해, 첨부된 도면을 참조하여 후술되는 본 발명의 바람직한 실시 예로부터 더욱 명확하게 될 것이다.     The above object and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention described below with reference to the accompanying drawings by those skilled in the art.
