Abstract

PURPOSE: A method for filling exterior finishing integral insulation materials is provided to keep warm at the part of tubing in an integral manner with the exterior finishing without a separate working such as a step of winding tapes on the tubing parts for the exterior finishing. CONSTITUTION: In the case of filling insulating materials at a simple tubing part, a vinyl sheet(2) is interposed between a female mold and a male mold. The heated male mold is pressed on the vinyl sheet and then is lifted up. Liquid urethane(4) is poured onto the surface of the vinyl sheet(2) of the female mold. Another male mold is pressed onto the liquid urethane container in the female mold in the heated state to form a half molding product. The half molding products are bonded with an adhesive on the tubing part. In the case of filling the insulating material at a complex tubing part(Ta), two boxes(10,10a) are engaged with each other and the complex tubing part is interposed therebetween. The liquid urethane is poured into the bonded boxes to form the insulating materials.

Description

The exterior finish all style lagging charge method of construction for complicated structure part of piping line}

The present invention is to prevent the freezing of the pipe in winter or to maintain the proper temperature of the conveyed material by blocking the conveyance in the piping work such as the pipeline for transferring liquid, gas, etc. in the factory, etc. in the glass fiber, foamed polyethylene on the outer surface of the piping Pipes made of polystyrene (Styropol), etc., which are insulated by installing foamed polyester or foamed heat insulating material, are "T" pipes, elbows and various types of valves, cocks, etc. In order to insulate the parts of simple or complex shape, and to insulate such complex parts, it has been insulated with insulation and then wound with vinyl tape on the outside.

However, in the case of T-type pipe, elbow or complex valve, it is difficult to install the insulation material in case of complex bending, whether glass fiber or foam polyethylene lock-wool is used as insulation material. In particular, the installation of the tape as an exterior finishing material is often difficult to realize the beautiful exterior effect, even if no effort is made by workers with a skilled function, so many people give up laying the insulation.

Therefore, it is common to expose straight pipes to insulation and finishing sheaths, and to expose T-type or complex valves without insulation or finishing sheaths.

In order to insulate complex parts as described above, the shape is not uniform according to the inclusion of insulation, and the vinyl tape is worn out due to the tape tape being worn out. But there have been problems such as not being insulated itself.

Piping line The piping line is mostly of the same shape in the case of various parts such as T-shaped pipes, valves, and cocks having a complicated external shape (for example, a simple type of pipe part 1 (shown in the drawing) of a “T” pipe). The parts are defined in various sizes according to the size, capacity, etc. according to the KS standard, foreign standards, etc., according to this standard, large and small complex pipe parts (1) of the same type are manufactured. The case of the piping component of a simple form as Example 1 to be described, and the case of the piping component of a complex form as Example 2 are as follows.

Example (1)

As shown in FIGS. 1 to 7, when the heat insulating material 30 is filled in the piping component T having a simple shape, first, a half of the required piping component shape is formed in the female mold 1 formed with the aesthetics and the conveyed material. Through the pipe parts finishing material of the color considering the type (hereinafter referred to as PVC sheet (2)) as shown in Fig. 2, the male mold (3) with high heat is combined and thermo-compressed, and then the male mold (3) is released. PVC sheet (2) in the form of a mold (1) is molded in the female mold (1) and in this state the liquid urethane (4) is injected into the surface of the PVC sheet (2) of the female mold (1) and then provided separately When the male mold (3a) is heat-molded to the female mold (1), the liquid urethane (4) is foamed by heat in the form of a cavity between the female and female molds (1) and (3a), and is molded into the female mold (1) and (3a) surface shapes. At the same time, the urethane 4 is foamed with the PVC sheet 2 integrally welded on the outer surface of the molded product 4a (insulating material). Demolding the molded article 4a molded in half shape of the part, and attaching and bonding the insulating member 30 to the piping component T having a simple shape as shown in FIG. In the case of the pipe part Ta having a complicated shape, the two boxes 10, 10a are used to combine the boxes 10 and 10a, and the inside of the pipe part Ta has a complex shape. The urethane 4 is injected and foamed to fill the thermal insulation material 30, thereby completing a thermal insulation material installation work of the piping part T having a beautiful appearance.
