Abstract
The utility model discloses a compound material pipeline, comprising a metal pipe 2 and a heat-insulating layer 3 which is arranged outside the metal pipe 2, and has the essential technology that an inner protective layer 1 is arranged on the inner wall of the metal pipe 2. The utility model has the advantages of corrosion resistant, wear resistance, flame retardancy, and antistatic performance, and can be widely used in chemical industry, energy resource industry, metallurgical industry, etc.
Description
The utility model relates to the FLUID TRANSPORTATION technical field, is a kind of composite material conduit.
Utilizing the line transportation flowing medium is one of requisite means of industry such as chemical industry, the energy.Under high temperature, high pressure, when carrying Korrosionsmedium, adopt Ordinary Steel or macromolecular material pipeline not ideal, and too expensive with its price of Stainless Steel Tube.
The purpose of this utility model is at the problems referred to above, and a kind of composite sheet pipe material that is made of metallic material and macromolecular material is provided.
Description of drawings:
Fig. 1: be the pipeline schematic representation of three-decker
Fig. 2: be the pipeline schematic representation of five-layer structure.
The utility model is to realize like this (referring to accompanying drawing):
A kind of composite material conduit, it adds thermal insulation layer 3 by metal tube 2 and constitutes, and its technological points is on the inwall of metal tube 2 inner protective layer 1 to be arranged.
More than said inner protective layer 1 adopt glass fibre reinforced plastic material, it and metal tube 2 bonding extrusion modlings are because employing extrusion modling new process middle small-bore pipeline inwall just is easier to be added with protective layer material.
In order to be suitable for down-hole and operation under the liquid level of aggressive medium; the utility model also can add two layers of material again in thermal insulation layer 3 outsides; promptly add one deck back-up coat 4; add one deck external protection 5 again; back-up coat 4 can be the reticular structure of metal wire knitted; also can constitute with iron sheet, iron sheet is wrapped on the thermal insulation layer 3 by miter angle.
Thermal insulation layer 3, external protection 5 all adopt glass fibre reinforced plastics; and inner protective layer 1 is except that with the glass fibre reinforced plastics; also can require to adopt PVC according to the difference of FLUID TRANSPORTATION; macromolecular materials such as teflon all adopt between thermal insulation layer 3 and the metal tube 2, between external protection 5 and the reinforcing metal layer 4 and twine bonding mode.
The composite material conduit that we say is divided into garden shape pipeline and special-shaped pipeline again by its cross section.
The utility model embodiment:
Example 1: pipeline section is a three-decker; internal diameter of the pipeline is between 15～450mm; wherein inner protective layer 1 adopts glass fibre reinforced plastics, metal tube 2 to adopt the seamless steel pipe of Ordinary Steel material, and thermal insulation layer 3 adopts glass fibre reinforced plastics, has added antistatic, flame retardant material in the material of this layer.
Example 2: pipeline section is a five-layer structure; internal diameter of the pipeline is between 15～450mm; wherein inner protective layer 1 adopts glass fibre reinforced plastics; metal tube 2 adopts cast iron tube; thermal insulation layer 3 outer back-up coats 4 are made up of the metal net shaped body of braided steel wire; external protection 5 adopts glass fibre reinforced plastic material, in this layer material, adds antistatic, flame retardant material.
Straight tube pipe section in the foregoing description, length can reach 6-20m.
The utility model can be used as the conveyance conduit of industrial chemicals, water coal slurry, Oil, Water, Gas body, coal slime ash and refuse (liquid or granular) fluid, it not only can use under-60-+200 degree celsius temperature condition, and having the corrosion of wear-resistant, anti-aging, acid resistant alkali and other hazardous mediums, it also has the good performance in fire-retardant, antistatic aspect; It can bear long distance, high flow rate, the fluid of big flow or the damage of dynamic loads such as extraneous mechanical shock, vibrations, the pipe joint of this pipeline can be divided into two kinds of demolition type and non-dismountable property, two types pipe connector all has enough strength and stiffness, at 200kg/cm
2Working pressure under still can keep good air-tightness.Pipeline can reach more than 30 years working life.
Claims (6)
1, a kind of composite material conduit, it adds thermal insulation layer 3 by metal tube 2 and constitutes, and it is characterized in that has an inner protective layer 1 on the inwall of metal tube 2.
2,, it is characterized in that metal tube 2 comprises straight tube, bend pipe and pipe connector thereof according to the described pipeline of claim 1.
3,, it is characterized in that inner protective layer 1 adopts glass fibre reinforced plastic material, it and metal tube 2 bonding extrusion modlings according to the described pipeline of claim 1.
4, according to the described pipeline of claim 1, it is characterized in that thermal insulation layer 3 added metal mesh reinforcement layers 4, back-up coat 4 adds external protection 5.
5, according to the described pipeline of claim 1, it is characterized in that thermal insulation layer 3 adds iron sheet back-up coat 4, back-up coat 4 adds external protection 5.
6, according to claim 4 or 5 described pipelines, it is characterized in that thermal insulation layer 3, external protection 5 all adopt glass fibre reinforced plastics, all adopt between thermal insulation layer 3 and the metal tube 2, between external protection 5 and the reinforcing metal layer 4 and twine bonding mode.
