There are 131j more than 8 and 8' to send m.

Generally speaking, the fluid is contained in a glass pipe, a metal plate installed on top of the plastic pipe, four sleeves, and one piece of moss. It consists of a plus-snack outer covering. The metal elephant ζ reinforcing layer increases the internal pressure of the glass pipe.
It is something that is meant to withstand the linear force in the direction of the linear force. Fluid shell 1
When the JJδ Shinnai Basin crude oil and flaming gas-like fluid are transported, the I-1 (J'tfl) or small scum-like components may be present due to the plastic pine and plastic sac pipe industry. If it stagnates in between, this waste pressure will rise and reach 0.

,' i)7. This gas pressure causes the stopped metal U- to bend over the glass pipe, and there is a danger that the gas pressure will cause the gas to blow out and cause a fire explosion. i11+J Bokubun 1 firefly pattern sleeve jimushi 1 cicada or 8% fi! it L sleeve 5 insect effect low] Sui 1. Therefore, when it comes to plastics, it is necessary to reduce the penetrability of the particles so that these particles escape to the outside.

With conventional technology, Qco 1, Kushi Snack outer plate T'', nylon,
Polyethylene or silicone rubber is used.
There was 1. However, the transmission coefficient of nylon is pitifully small, and polyethylene is υ larger than that of nylon, and the total gas effect V is still present, Cf = u opaque transmission coefficient. f: +-J. On the other hand, silicone rubber has a high permeability coefficient, but is durable.

However, it is not useful.

The purpose of ``Fujitsu'' is to improve the gas permeability of large trees and the resistance to hemorrhoids.
□Toniru provides fluid transport with a complete plastic outer covering that is both abrasion and oil resistant. ``Embodiments of the present invention, of course, are shown in detail. The drawings show a fAt body transport pipe 10 according to the present invention, and the body transport tube 10 is equipped with a hot hole such as nylon.

This plastic jacket has 16 parts and is printed.

The gold-striped sleeve strong pigeon 14 is, for example, a gate spider made by spirally wrapping the obi in multiple layers □ Forceful L4 A and external reinforcement made by twisting gold A and station wire R like iron wire Although the inner reinforcing layer is made of layer 14B, the inner reinforcing layer may be formed by cutting a cross section, meeting the top and bottom of the gold and peng If in the opposite direction, and wrapping it once.

The plastic jacket 16 is a self-contained composite of polyethylene and silicone rubber. Poirier, Ji, Ren vj: Commercial 11 meeting, middle 'at L history, low VB degree, ・,'1:1. ：、1゜Good?

□-・If the silicone rubber is commercial silicone elastomer, it is especially good! I'm not sure, but is it possible to use it alone or as a filler? 1. 'fC' is used by blending other rubbers such as edelene clobylene rubber.

The blending ratio of polyethylene and silicone rubber is not limited to bamboo, or is in the range V1 of Karibatake 10:90 to 90:10.
If you get lost, you can use iL. In this way, a combination of polyethylene and silicone rubber is used. By forming the f'2t-tic outer sheath 16, it maintains both the abrasion resistance, one-shot oil resistance, and the permeability of the polyurethane. ,, can you have it? - Overall, less polyethylene reduces the T & Q h properties and oil resistance of the plastic jacket, and reduces the permeability and gas permeability.

: Therefore, the blending ratio of vorietepine and silicone rubber is
A particularly favorable range is 30:70 to 65:3.

-Unfortunately, silicone rubber is used in an unvulcanized state, and is also used after being vulcanized with a mixture of superoxides, but the silicone rubber used in the present invention is It may be sulfurized or vulcanized.

Dicumyl peroxide or dicumyl peroxide is used.

The carbon dioxide gas was completely flowed at a pressure of Ky/d, and the nylon pipe and plastic jacket were exposed to a pressure of 1U'' and the plastic jacket was heated to 4-bar. The silicone rubber used is Tou J.
