Description

[0001] PROTECTION COVER ASSEMBLY FOR GAS PIPE LINE [0002]

The present invention relates to a protective cover assembly for a gas piping, and more particularly, it relates to a protective cover assembly for a gas piping, in which a heater can be simply installed in a piping of a gas so that a piping of gas transferred to a semiconductor manufacturing process can maintain a constant temperature, To a protective cover assembly for a gas piping.

Generally, the gas transferred to the semiconductor manufacturing process is transferred through the piping. However, when the temperature of the piping is lowered during the transfer, liquefaction phenomenon and powder generation occur in some gas. Therefore, a heater is usually installed on the outer circumference of the gas piping do.

However, in such a heater, a heater coil is provided in a heating jacket having a predetermined area and is installed in a gas pipe. However, the heating jacket is made of cloth or cloth, and a heater coil is disposed inside the heating jacket There is a problem that the manufacturing process is complicated due to the installation and the production amount is lower than the manufacturing cost. In addition, since the thermal insulation of the heating jacket is lowered, the gas piping can not be maintained at a constant temperature, and some of the transferred gases are liquefied and the powder is generated, thereby causing defects in the semiconductor product.

In order to solve the above-mentioned problems, as shown in FIG. 1, a heater coil 1 connected to a power source is connected to a circumference of a gas pipe 3 And a protective pipe (2) made of Teflon is installed on the outer side of the pipe to receive the heater coil (1).

However, in order to maintain the temperature of the gas piping, the heating device is required to wind the heater coil along the circumference of the gas pipe and to install a Teflon protective pipe on the outside thereof, so that the heater coils are installed at regular intervals There is a difficulty.

In addition, when the heater coil and the protective tube are replaced, work is performed in a narrow space, resulting in poor workability and a long time.

2, a heater connected to a power source is installed along the longitudinal direction of the gas pipe, and a protective cover for high temperature is surrounded by a gas pipe and a strap is used A gas piping heating apparatus for connecting a high temperature protection cover to a gas piping is used.

However, such a gas piping heating apparatus has a complicated work process and has a problem that a space where a protective cover is partially opened, as shown in a circle in FIG. 3, is generated and the heat insulating effect is deteriorated.
