Abstract

A glass fiber dipping polyethylene resin composite pipe is characterized in that the pipe consists of a polyethylene pipe (1) and a glass fiber layer (2). The outer layer of the polyethylene pipe (1) is provided with the glass fiber (2). The polyethylene pipe of the joint is connected through welding. The outer glass fiber layer (2) consists of the continuous glass fiber rounding dipping lipid layer (3).

Description

Polythene glass fibre resin-immersing composite pipe

One, technical field:

The utility model relates to a kind of novel polyethylene pipeline, particularly relates to a kind of polythene glass fibre resin-immersing composite pipe.

Two, background technique:

Plastics are that this century is with fastest developing speed, one of most widely used new material, plastic pipe has the not available many advantages of conventional pipelines material because have characteristics such as Economy, corrosion-resistant, easy construction, is widely used in fields such as plumbing, combustion gas conveying, industry and agricultural.

Polyethylene pipe (HDPE) has some unique character, and the incomparable advantage of other pipeline material is arranged: the physical property that (1) is good: a, little, in light weight, the transportation, easy for installation of density; B, serviceability temperature scope are wide, and cryogenic property is good, is specially adapted to extremely frigid zones and various rugged environment; C, Young's modulus are little, and its internal stress is less when temperature fluctuation, can guarantee pipeline and safe handling effectively; D, thermal conductivity are low, and 0.42W/m.k is only arranged, and can play good insulation effect; E, has good electrical properties; (2) good chemical stability is arranged, corrosion resistance and good is because the HDPE molecule is nonpolarity, so chemically stable is good, factors such as the soil in the general Environmental Conditions, electric power, acid, alkali can not make this pipeline corrosion or infringement, can breed bacteria yet, microorganism or careless class etc.Except that the minority strong oxidizer, most of chemical mediators are inoperative to it under the room temperature.(3) low frictional resistance, prevent fouling, cut down the consumption of energy, HDPE inner tube wall surface roughness has only 0.01mm, the frictional resistance resistance coefficient is minimum, and in service life, can not change in time. in liquid flow system, the HDPE internal diameter that reaches identical traffic requirement pipe is littler than steel matter internal diameter of the pipeline, and institute's energy requirement is low.; (4) good impact resistance HDPE tubing has good pliability and impact resistance, even there is 2.5 times worker to claim the water hammer pressure of pressure also can not cause any infringement to pipeline.(5) pliability is good, and the material specific elongation is big, and brittle temperature low (70 ℃) can be impacted by absorbing medium; (6) the good flexible trend of polyethylene pipe that makes of polyethylene changes according to the requirement of method of construction easily.The tensile strength of the incorporate welding connection interface of pipeline is higher than the tubing body, can effectively resist axial tensile stress; (7) polythene material has good anti-scratch trace ability, and under the same conditions, HDPE and steel pipe are done wear-resisting experiment contrast, and the result shows: the wear resistance of HDPE pipeline is 4 times of steel pipe.

The shortcoming of vinyl tube is that big medium caliber pipeline bearing capacity is poor, has influenced its use in water supply line, gas transmission line, oil field extracted water re-injection pipeline, all types of industries pipeline, submerged pipeline and mixed transportation of oil and gas field.

Three, summary of the invention:

The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, the polythene glass fibre resin-immersing composite pipe that provides the performance such as anti-corrosion, wear-resisting of a kind of high strength of utilizing glass fibre and plastics to make.

Its technological scheme is: be made up of polyethylene pipe (1) and glass fibre layer (2), skin at polyethylene pipe (1) is provided with glass fibre layer (2), wherein, the inner layer polyethylene pipeline of joint connects by melting welding, and outer field glass fibre layer (2) is made up of the glass fibre resin-immersing repair layer (3) of continuous winding.

Described glass fibre layer and glass fibre resin-immersing repair layer all are made up of the glass fibre that immerses resin of continuous winding.

The beneficial effects of the utility model are: thoroughly solve the Corrosion of Pipeline problem, the operation period of pipeline is hopeful to bring up to 50-100, and after finishing, pipeline construction need not carry out the maintaining in later stage substantially, significantly reduced the maintenance cost in the running, the operation period cost of pipeline has reduced greatly.

Four, description of drawings;

Accompanying drawing 1 is a sectional view of the present utility model;

Accompanying drawing 2 is side views of the present utility model.

Five, embodiment:

In conjunction with the accompanying drawings 1,2, the utility model will be further described:

Its technological scheme is: be made up of polyethylene pipe 1 and glass fibre layer 2, be provided with the glass fibre layer 2 of immersion resin at the skin of polyethylene pipe 1; Wherein, the inner layer polyethylene pipeline of joint promptly can connect by melting welding, in order to increase join strength, the glass fibre resin-immersing repair layer 3 that outer field glass fibre layer 2 is made up of the glass fibre that immerses resin of continuous winding, the joint outer wall twines the high strength glass fiber that immerses resin, and its intensity is 1.2 times of common polythene glass fibre resin-immersing composite pipe intensity.

Its making way: the vinyl tube of intercepting certain-length axially moves when making its rotation; Be wrapped on the vinyl tube outer wall after again the multiply leached glass fiber being gone into resin, make it can bear higher pressure, the thickness that glass fibre is wrapped on the vinyl tube outer wall determines according to the pipe working pressure.
