    摘要: 본발명은시공이편리한새로운구조의탐색이가능한지중배관에관한것이다. 본발명에따른지중배관은상기관체(A)가전방의삽입부(11)와, 상기삽입부(11)의후방에형성되며내경이상기삽입부의외경에대응되도록구성되어내부에다른관체(A)의삽입부(11)가끼움결합되는결합부(12)로구성되고, 상기삽입부(11)의외주면과상기결합부(12)의외측면과후단면및 내주면에는전도성도료를도포한도전층(20)이상호연결되도록형성되어, 상기관체(A)를다른관체(A)의결합부(12)에끼움결합하면상기도전층(20)이상호접촉되어각각의관체가상호전기적으로연결된다. 따라서, 2개의관체(A)를연결하는것만으로관체(A)를상호전기적으로연결할수 있음으로, 관체(A)를상호연결한후 별도의도전체를이용하여관체(A)를상호전기적으로연결하여야하는종래의지중배관에비해, 설치작업이매우간단한장점이있다.

    摘要: PURPOSE: A pipe fixing anchor is provided to prevent damage to an outer cylinder due to pressure caused by concrete during the construction of a slab by the formation of a reinforcing rib on the outer cylinder. CONSTITUTION: A pipe fixing anchor comprises an outer cylinder(100) and an inner cylinder(200). The outer cylinder vertically passes through the slab and is buried inside the slab. The inner cylinder is coupled inside the outer cylinder. A target pipe(20) is inserted into the inner cylinder and is fixed by a fixing unit and is sealed with the inner cylinder.

    摘要: PURPOSE: A polyamide-based multilayer tube having superior barrier action against gasoline for transporting gasoline with superior dimensional stability even under severe temperature conditions is provided. CONSTITUTION: Layers (1-3) are provided toward the outside from the inside. A first layer (1) consists of a mixture of polyamide P1/polyolefin (PO1) having polyamide P1 as a matrix or the first layer (1) consists of polyamide P1. The layer (2) consists of copolyamide and the layer (3) consists of polyamide P3. P1 and P3 are same or may be different and respective layers (1, 2, 3) are continued and mutually bonded in the respective contact regions. Furthermore, an EVOH layer or a layer containing conductive carbon black may be added to these three layers (1, 2, 3).

    摘要: PURPOSE: A coextruded multi-layer tubing assembly is provided which has an inner fluoroplastic permeation resistant layer, a middle adhesive layer, and a non-vulcanized rubber-like multiphase polymer cover layer. CONSTITUTION: A tubing assembly includes an extruded innermost semi-conductive fluoroplastic layer. The fluoroplastic is made semi-conductive by mixing it with 1% to 10% by weight of conductive carbon black. Metallic conductive fillers such as silver, copper or steel are utilized. The tubing assembly has a surface resistivity in the range of about 10 to 1000000 ohm/sq, with a preferential range of 100 to 100000 ohm/sq. Herein, Suitable fluoroplastics include ETFE(ethylene tetrafluoroethylene), THV(a terpolymer of tetrafluoroethylene, hexafluoropropylene and vinylidene fluoride), PVDF(polyvinylidene fluoride) or blends of these fluoroplastics. An inner permeation-resistant fluoroplastic layer coextrudable at temperatures below 600 degrees Fahrenheit is coextruded with and surrounds the innermost semi-conductive layer.
