Abstract
A high-strength composite plastic pipe with metal skeleton for conveying gas and liquid features that the metal skeleton is fused in the middle layer of plastic pipe. The metal framework is a tubular metal grid, or a hole is punched on a metal sheet and then the metal sheet is rolled into a tube shape. The plastic adopts polyvinyl chloride or polyethylene or polypropylene or polytetrafluoroethylene, or melts lithium, potassium, sodium and chlorine trifluoride in the polytetrafluoroethylene. The utility model has the advantages that: the high-strength metal framework plastic composite pipe not only has high mechanical strength, but also has corrosion resistance inside and outside the pipe; light weight, low cost and convenient installation.
Description
The utility model relates to the pipeline of conveying gas, liquid.
In industries such as petrochemical industry, food processing, pharmacy papermaking, metallurgy, mining, tap water, the conveying of gas, liquid has the pipeline of various materials, various structures.The pipeline that uses has steel pipe, plastic tube, Stainless Steel Tube, steel inwall plastic-blasting pipe, steel-plastic composite pipe, steel inwall line with rubber pipe etc. at present.Steel pipe is subject to the corrosion of gas, liquid, especially when carrying corrosive gas, liquid, exposes its weakness more; Plastic tube has corrosion resistant function, but mechanical strength is too poor, fragile; Stainless Steel Tube also can corrosion protection, but that it is worth is expensive; Steel inwall plastic-blasting pipe, steel-plastic composite pipe have certain mechanical strength and the inner antiseptic property of pipe, but that steel is moulded two kinds of material coefficient of thermal expansion and contraction is different, when temperature variation, can produce stress, influence its usability, can rupture when serious, the outside metal of pipe still can be corroded; The manufacturing process of steel inwall plastic-blasting pipe, steel inwall line with rubber pipe is carried out at the steel pipe inwall, and technical difficulty is big.
The purpose of this utility model is to provide a kind of high duty metal frame plastic composite pipe in order to overcome above-mentioned deficiency, not only has good mechanical strength, and its inwall and outside all have corrosion proof function; The mutual fusion of metal frame and plastics, stress distribution is even; Manufacturing process is simple, and cost all comes lowly than existing pipeline.
Description of the present utility model is as follows: the high duty metal frame plastic composite pipe is the interlayer melted metal frame at plastic tube, that is to say, the tubular metal skeleton is contained by inside and outside layer plastics.Metal frame is the metal grill of tubulose, or goes out the shape that Kong Houzai one by one is rolled into pipe on sheetmetal.The mode that the combination of metal frame and plastic tube adopts heat to melt, push, plastics are inlayed in the metal grill gap according to different usage requirements, plastics can adopt PVC or polyethylene or polypropylene or teflon, or in teflon molten metal lithium, potassium, sodium, chlorine trifluoride.
Description of drawings:
Figure is the structure sectional view of high duty metal frame plastic composite pipe of the present utility model.Among the figure 1---plastic tube, 2---the tubular metal skeleton.
The caliber of high duty metal frame plastic composite pipe is from DN10～DN24000 millimeter.With the high duty metal skeleton polyethylene compound pipe of 98 millimeters of internal diameters, 130 millimeters of external diameters as embodiment of the present utility model.The material of plastic tube (1) is a polyethylene.Metal frame (2) is made 10 * 10 millimeters grid with the steel wire of 1 millimeter of φ, and is rolled into 114 millimeters of tubulose φ.Melt extruding by plastic hot, make metal frame be contained 16 millimeters of metal frame plastic composite pipe wall thickness by plastic tube.
Advantage of the present utility model: high-intensity metal carcase plastic compound tube not only has Certain mechanical intensity, and the inside of pipe, outside all have antiseptic property; Weight Gently, cost is low, easy for installation.
Claims (3)
1. a high duty metal frame plastic composite pipe that relates to conveying gas, liquid is characterized in that the interlayer melted metal frame at plastic tube.
2. high duty metal frame plastic composite pipe according to claim 1 is characterized in that metal frame is the metal grill of tubulose, or goes out the shape that Kong Houzai one by one is rolled into pipe on sheetmetal.
