Abstract

The utility model relates to a metal-lining glass fiber reinforced plastic composite pipe which is composed of a glass fiber reinforced plastic pipe (1) and a metal lining layer (2). The utility model is characterized in that the glass fiber reinforced plastic pipe (1) is formed by across laying glass fiber yarns (3) in an annular direction and longitudinal glass fiber yarns (4), wherein the glass fiber yarns (3) in an annular direction are distributed around the pipe circumference; the longitudinal glass fiber yarns (4) are parallel to the axial lead of the glass fiber reinforced plastic pipe (1). Metallic belts (5) are wound on the inner wall of the glass fiber reinforced plastic pipe (1) and are used as the metal lining layer (2), and an included angle alpha is formed between the metal belts (5) and the axial lead of the glass fiber reinforced plastic pipe (1). The utility model effectively combines metal material and non-metal material, fully utilizes the individual advantages, not only solves the static and problems, but also has the advantages of corrosion resistance, leakage prevention, good intensity and good and moderate price.

Description

The metal inner lining glass fibre reinforced plastic composite pipe

One, technical field:

The utility model relates to a kind of pipeline, especially is applicable to the metal inner lining glass fibre reinforced plastic composite pipe of coal mine gas extraction, plumbing, pressure wind, whitewashing.

Two, background technique:

At present, pipeline commonly used both at home and abroad has metal species pipeline and non-metal kind pipeline, and metallic conduit has stainless steel, welding carbon steel, spheroidal graphite cast iron, aluminium, copper pipe; The non-metal kind pipeline has cement, PVC, Glass Steel Tube.The shortcoming of aforementioned two class pipelines is: metal species pipeline price height, and easy-to-rust, density is big, the installation inconvenience.The cement pipe rough surface of non-metal kind is crossed water, to cross atmidometer big, water tightness, poor air-tightness, thick and heavy, install inconvenient; Polyvinyl chloride pipe is not fire-retardant, not antistatic, and intensity is low, not UV resistant and atmospheric corrosion; Though at present used Glass Steel Tube is than other several pipeline advantages, because its glass fibre intersects laying by oblique fiber that tilts with the pipeline shaft axis and hoop glass fibre, thereby, there is the heterogeneity problem, the vertical and hoop intensity inequality of pipeline.In addition, fire-retardant, antistatic, the UV resistant of pure fiber reinforced plastic pipe and intensity, rigidity than metallic conduit a little less than.

Three, the content of model utility:

The purpose of this utility model provides a kind of moderate cost, and is corrosion-resistant again, antistatic, fire-retardant, and metal inner lining glass fibre reinforced plastic composite pipe in light weight, that intensity is high.

In order to achieve the above object, concrete scheme of the present utility model is: a kind of metal inner lining glass fibre reinforced plastic composite pipe, comprise Glass Steel Tube, its key is: A, Glass Steel Tube are laid by hoop glass fiber yarn and vertical glass fiber yarn intersection and are formed, wherein the hoop glass fiber yarn is pressed the circle distribution of pipeline, vertically the axis parallel of glass fiber yarn and Glass Steel Tube; B, the metal tape that has shaft axis with Glass Steel Tube to be an angle α in the solderless wrapped connection of Glass Steel Tube inwall are made the metal inner lining layer.

The utility model with the glass fibre reinforced plastic structure layer press the hoop glass fiber yarn and vertically glass fiber yarn intersect and lay, can overcome the heterogeneity problem of composite material, can give full play to that pipeline is vertical, the strength characteristics of the main force part of hoop simultaneously.Make inside liner at Glass Steel Tube inwall solderless wrapped connection metal tape, not only increased the ability of fire-retardant, antistatic, UV resistant and atmospheric corrosion, and lower than pure metal pipeline cost.

Adopt the beneficial effect of such scheme to be: to make the effective combination of metallic material and nonmetallic material, demonstrate fully advantage separately, not only solved fire-retardant, anlistatig problem, and make product have the advantage of corrosion-resistant, anti-intensive ultraviolet and atmospheric corrosion, and strength and stiffness height, price are moderate again.

Four, description of drawings:

Fig. 1 is a plan view of the present utility model;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the fibrous structure unfolded drawing of Glass Steel Tube 1 among Fig. 1;

Fig. 4 is the metal tape 5 distributed architecture unfolded drawings of metal inner lining layer 2 among Fig. 1.

Five, embodiment:

Please see Figure 1, Fig. 2, the utility model mainly is made up of Glass Steel Tube 1 and metal inner lining layer 2.Can see that in conjunction with Fig. 3 Glass Steel Tube 1 is laid with vertical glass fiber yarn 4 intersections by hoop glass fiber yarn 3 and formed, wherein hoop glass fiber yarn 3 is pressed the circle distribution of pipeline, vertically the axis parallel of glass fiber yarn 4 and Glass Steel Tube 1; As Fig. 2, shown in Figure 4, make metal inner lining layer 2 at the metal tape 5 that Glass Steel Tube 1 inwall solderless wrapped connection has shaft axis with Glass Steel Tube 1 to be an angle α.

Also can see from Fig. 4: solderless wrapped connection is 55～57 ° at the metal tape 5 of Glass Steel Tube 1 internal surface and the angle α of Glass Steel Tube 1 shaft axis.

Further learn in conjunction with Fig. 1, Fig. 4: metal tape 5 uniform ring in the described metal inner lining layer 2 of present embodiment are around Glass Steel Tube 1 internal surface.Select the metal tape (paper tinsel) of different in width for use according to different calibers, the little metal tape of caliber (paper tinsel) is narrow, and the big metal tape of caliber (paper tinsel) is wide.That this layer mainly plays is fire-retardant, leakage proof, etch-proof effect.

Glass Steel Tube 1 described in the utility model mainly plays the effect of the bearing pressure and the power of transmission, according to different pressure and rigidity, and the different laying number of plies of design glass fibre.The number of plies is many more, and pressure that is carried and rigidity are high more, otherwise pressure that is carried and rigidity are just low.According to the difference of power thrusts, regulate the number of plies of different direction upper glass fleece-laying, increase axial stress if desired, then increase the radially shop layer of yarn, increase circumference stress if desired, then increase the shop layer of hoop yarn.The total thickness of Glass Steel Tube is not less than 3mm.
