The tubular cover 410 is coupled in such a manner that one side and the other side of the square plate-shaped first plate-shaped cover are opposed to each other and are wrapped in a tubular shape, and one side and the other side of the first plate- '

≪ RTI ID = 0.0 > 412 < / RTI &
The first plate-shaped cover is provided with a friction fixing portion 411 so that the inside and the outside of the tubular cover 410 are sealed with each other. The friction fixing portion 411 is made of a resilient material A first friction fixing member 4111 and a second friction fixing member 4112,
The friction connecting portion 412 has a first friction connecting member 4121 of elastic material and a second friction connecting member 4121 of elastic material at positions corresponding to the first friction fixing member 4111 and the second friction fixing member 4112 on one side and the other side, And a connecting member 4122,
A plurality of projections are formed on the surfaces of the first friction fixing member 4111 and the second friction fixing member 4112 and the first friction connecting member 4121 and the second friction connecting member 4122 which are in contact with each other Respectively,
The opposite ends of the first friction fixing member 4111 and the second friction fixing member 4112 face each other to form an arc and protrude outward so as to contact the inclined surface of the friction connecting portion 412,
In the case where two or more pipes P are provided perpendicularly to each other and are flanged to each other, the first pipe Pa located on the upper side is provided with the first external cover portion 400a, (Pb) is provided with a second external cover portion 400b,
And is disposed between the first outer cover portion 400a and the second outer cover portion 400b and surrounds the flange,

Shaped connection cover part 500 whose cross section is rotated by 360 degrees,
One end of the connection cover part 500 is inserted into the first outer cover part 400a and the other end is inserted into the second outer cover part 400b,
A caulking member 510 is applied and sealed between one end of the connection cover part 500 and the first external cover part 400a,
The other end of the connection cover part 500 and the second outer cover part 400b are opened while the end of the second outer cover part 400b is in contact with the flange, The rainwater flowing between the second outer cover portion 400b and the connection cover portion 500 is discharged without flowing rainwater between the connection cover portion 400a and the connection cover portion 500. [ Cover for.
delete delete delete delete The method according to claim 1,
The heat insulating material 100 is made of a material including perlite,
The fiber cover 310 is formed of a lattice-shaped glass fiber material. The fiber cover 310 improves the heat insulation property to increase the duration of keeping the inside of the pipe P,
The wire 200 is made of galvanized material to prevent corrosion of the pipe P and the pipe cover,
Wherein the desiccant (320) is made of vinyl material and is coated at least twice to prevent moisture from being generated inside the pipe cover.
