部材が内在された合成樹＋１１’ｉ管に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a synthetic wood +11'i pipe that is integrally provided with the pipe wall or has a metal reinforcing member embedded in the pipe portion.

ナック複合管等が用いられている。As pipes to be buried underground, conventionally used are humid pipes, steel pipes, asbestos pipes, reinforced defusnack composite pipes, etc., which are easily broken and have excellent pressure resistance.

らもコストアップが余儀なくされている。This is especially true for large-diameter pipes. However, since Huyum pipes and W4 pipes are corrosion resistant, chemical resistant, and heavy, they require careful handling, which greatly limits their applications. However, there are some drawbacks such as high cost. Asbestos pipes, glass-fiber, and reinforced plastic composite pipes are expensive to manufacture.Reinforced glass composite pipes in particular take too much time and effort to manufacture, and require a large amount of raw material usage, which also increases costs. I'm forced to.

ことが原因となっている。However, the rigged synthetic tree B'1l-1ft, which is made from thermosetting synthetic resin such as polyester resin, has a pressure of 11cm and 1cm.
1.It has excellent corrosion resistance and chemical resistance, but this method is made by coating a polyester resin on a metal reinforcing member fitted into a synthetic resin pipe and covering a mat-like glass fiber. This is done using a Hi hand lay-up method where gold such as n is applied in several layers and cured. Q) There is a flat bend in the manufactured bum, and the cost is high. This method of manufacturing 9fx is adopted because, when using thermosetting synthetic resin raw materials, the synthetic resin 'H is not extruded. This is because there was no proper means for embedding the component into the synthetic resin layer of the lip.

It is an object of the present invention to provide an inexpensive long synthetic resin pipe, and to provide a manufacturing apparatus that can easily and continuously mold such a long synthetic resin pipe by extrusion molding.

トダウンにつながることが明らかになっている。Figure 2 shows the lip (102) formed on the tube wall (101).
is shown in detail. As is clear from this,
A metal ring-shaped reinforcing member (108) is tightly embedded in the lip portion (102). With this configuration, the elongated synthetic resin pipe (100) has a wall (101) reinforced by the lip portion (102), and a metal reinforcing member (10B) that strengthens the lip portion (102). Due to the synergistic effect of this product, it has a very high compressive strength, and can be used as a substitute for the above-mentioned hume pipes, steel pipes, asbestos pipes, and reinforced plastics. It becomes. In addition, it has been found that when polypropylene containing 80% glass fiber is used as the thread material for the synthetic resin, it has a compressive strength up to five times that of one made from only polypropylene. ing. Furthermore, a lip part (102) is added to the long synthetic tree (100) explained in FIG.
The thickness of the lip (102) is approximately twice the thickness t1 of the tube wall (101), and the thickness t1 of the lip (102) is
If the metal reinforcing part (108) is embedded in the rig part (102) as described above, the pressure resistance is the same and the thermoplastic synthetic resin pipe without the reinforcing member is approximately 8 times as large as 1. It has been revealed that the raw material usage Jn is 40% or less compared to the previous method, leading to significant cost reductions.

トダウンが達成される。As detailed above, since the raw material for the synthesized bicarbonate pipe according to the present invention is thermoplastic resin, it not only has excellent corrosion resistance and corrosion resistance, but also has excellent corrosion resistance and corrosion resistance. Since a metal reinforcing member is embedded in the lip part, the synergistic effect VC of the reinforcing action of the lip part by the reinforcing member and the reinforcing action of the a wall by the lip part increases the pressure resistance of the metal fitting T・18. (
i], and even if it is a large diameter one,

It can be used as a replacement for ``G'' and has a good QC. In addition, by embedding metal reinforcing parts, the cost of raw materials can be reduced accordingly, and combined with the fact that inexpensive thermoplastic synthetic resin is used as raw material, conventional fumes, reinforced plastic pipes, etc. A significant cost reduction is achieved compared to each of the above TGs.
