연관을 내장한 통기성 강관Breathable steel pipe

제1도는 본 고안의 사시도.1 is a perspective view of the present invention.

제2도는 본 고안의 확대 단면 설명도.Figure 2 is an enlarged cross-sectional view of the present invention.

본 고안은 산(酸)이나 염기성(鹽基性)물질 또는 부식 유체(流體)를 유통되게 하는 연관(鉛管) 내장 강관에 있어서 연관의 전표면에 천연섬유 또는 합성섬유사를 나선상이나 망목상으로 회권하여 통기성 모세공(毛細孔)을 형성함과 동시에 외부 강관에 통기공을 천설하여 내부 유통물의 온도가 변화됨에 따라 연관에 발생하는 팽창 변형되는 주름살이 수축 현상으로 복귀됨을 용이하게 한 것인데 본 고안은 고온의 유통물에 의하여 팽창되어 생기는 주름살을 용이하게 원상으로 복귀시켜 팽창된 연관이 팽창율이 낮은 강관의 내면에 용이하게 밀착 될 수 있게 한 연관은 내장한 통기성 강관에 관한 것이다.The present invention is a spiral or mesh network of natural or synthetic fiber yarns on the entire surface of a tube in a tube built-in steel pipe allowing acid, basic substances, or corrosive fluids to circulate. By forming a breathable capillary hole and forming a ventilator in the outer steel pipe at the same time as the temperature of the internal distribution changes, it is easy to return the expansion and deformation wrinkles generated in the association to the contraction phenomenon. The association relates to a built-in breathable steel pipe in which the wrinkles produced by the hot flow are easily returned to their original shape so that the expanded connection can be easily adhered to the inner surface of the low-expansion steel pipe.

종래 산이나 염기성 물질 또는 부식성 유동체를 유통하는데 사용하는 파이프는 통상적으로 연관을 내부에 라이닝한 강관이 사용 되고 있는 것이나 내부의 유통물의 온도 변화에 따라 그 팽창계수가 강관보다 매우 큰 연관은 강관의 내면에서 박리 되면서 굵은 주름살 형상으로 변형되어 내부물질의 유통을 방해하게 되는데 이 현상은 항시 반복되는 것이여서 사용 중 연관에 균열이 발생되어 유통물이 누설되면 외부강관이 부식되어 외부강관이 산화 부식되는 결점이 있게 되는 것이다.Conventionally, pipes used to distribute acid, basic materials, or corrosive fluids generally use steel pipes lining the inside of the pipe. When peeled off, it transforms into a thick wrinkled shape and hinders the distribution of the internal material. This phenomenon is repeated all the time. If a crack occurs in the pipe during use and leaks, the external steel pipe is corroded and the external steel pipe is oxidized and corroded. This will be.

본 고안은 연관을 내장한 강관에 있어서 전기와 같은 결점을 제거코져 고안한 것으로서 고안의 요지를 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is designed to remove the defects such as electricity in the steel pipe with a built-in as described in detail the subject of the design by the drawings as follows.

연관 내장강관(1)에 있어서, 연관(2)의 주면에 천연섬유나 합성섬유사조 (3) (3')를 나선상이나 망목상으로 회권하여 강관(1)에 삽입되게 하되 강관(1)에 수개의 통기공(4)(4')을 형성되게 한 것이다.In the associated internal steel pipe (1), natural fiber or synthetic fiber thread (3) (3 ') is wound on the main surface of the pipe (2) in a spiral or mesh shape so as to be inserted into the steel pipe (1), but not in the steel pipe (1). Several vent holes 4 and 4 'are formed.

이와 같이 된 본 고안을 실시함에 있어서,In carrying out the present invention as described above,

본 고안은 강관(1)의 내면에 연관(2)을 삽장함에 있어서 연관(2)의 표면에 천연섬유사나 합성섬유사조(3)(3')을 나선상이나 망목상으로 회권하고 강관(1)에 통기공(4)(4')을 천설한 것이어서 내부의 유통물의 온도 변화로 인하여 연관(2)이 팽창 되거나 수축 될시 생기는 주름살을 용이하게 원상으로 복귀 시키기 위하여 연관(2)의 전표면에 섬유사조(3)(3')을 나선상이나 망목상으로 회권 하여서 그 팽창 수축으로 인한 양관 사이에서 발생하는 공기압을 강관의 통기공(4)(4')에 의하여 대기에 연통되게 하여 조절되게 한 것이여서 연관에 국부적인 팽창 변형이 야기되지 아니 할뿐 아니라 고온으로 인한 팽창 변형이 야기 되드라도 유통물의 내압과 연관 표면에 회권한 섬유사조 (3)(3')에 의하여 균등하게 분포됨과 동시에 쉽게 원상대로 복귀하게 되는 것이여서 연관에는 종래와 같이 국부적인 팽창 변형이 발생되지 아니하고 전체 길이에 긍하여 평준하게 팽창 되었다가 평준하게 수축되는 것이므로 팽창 변형으로 인한 균열이 발생되지 아니하고 외부의 강관과 더불어 사용 수명을 연장되게 한 효과가 있는 것이다.In the present invention, in inserting the tube (2) on the inner surface of the steel pipe (1), the natural fiber yarn or synthetic fiber yarn (3) (3 ') on the surface of the tube (2) turns into spiral or mesh, and the steel pipe (1 Ventilation holes (4) and (4 ') are installed at the front surface of the tube so that the wrinkles generated when the tube (2) expands or contracts due to the temperature change of the internal circulation can be easily returned to its original shape. The fiber thread (3) (3 ') is wound into a spiral or mesh, so that the air pressure generated between both pipes due to the expansion and contraction is communicated to the atmosphere by the vent holes (4) (4') of the steel pipe. Not only does not cause local expansion deformation in the associating but also causes the expansion deformation due to high temperature, while it is distributed evenly by the fiber thread (3) (3 ') wound on the internal pressure of the circulation and the associating surface. It is easy to return to its original position As the pipe does not generate local expansion deformation as in the prior art, it expands evenly in favor of the entire length and contracts evenly. Therefore, the pipe does not generate cracks due to expansion deformation and has an effect of extending the service life together with the external steel pipe. It is.
