Description
Technical field
The present invention relates to a kind of Twin channel steel-plastic composite pipe that can carry two kinds of different mediums simultaneously, be mainly used in the conveying of liquid, gas and powder.
Background technique
The Twin channel steel-plastic composite pipe is to be parent tube (like the Ordinary Steel pipe) with the steel pipe; Inside and outside layer application of high temperatures is coated with molding technology; Epoxy resin (EP) or polyethylene (PE) coating are coated on the inside and outside tube wall of parent tube equably, after solidifying, form smooth, smooth, the firm protective layer of one deck at tube wall, it had both kept original intensity of steel pipe and rigidity; Good insulating property are arranged again; Erosion that also can acidproof alkali salt can used under serious rugged environment for a long time, thereby has prolonged the working life of steel pipe greatly.For example the utility model patent name is called: a kind of steel-plastic composite pipe of antirust acidproof alkali salt; The patent No. is: ZL2010201080256.But it does not carry liquid, gas and the powder of two kinds of different mediums simultaneously in same pipeline function.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency that exists in the existing technology, and a kind of structure art designs advantages of simple is provided, can carry the convenient again Twin channel steel-plastic composite pipe that replacement is installed of two kinds of different mediums simultaneously.
The present invention addresses the above problem the technological scheme that is adopted: a kind of Twin channel steel-plastic composite pipe, it is characterized in that being provided with outer composite pipe and interior composite pipe, and said interior composite pipe, outer composite pipe all adopt steel to process and be provided with complex coating; Interior composite pipe periphery is installed the rubber-like positioning device, in the outer composite pipe deck is installed, and interior composite pipe is inserted in outer composite pipe; Positioning device and deck are connected; Composite pipe passage in interior composite pipe constitutes, the space constitutes outer composite pipe passage between outer composite pipe and the interior composite pipe, and said positioning device is made up of strut and draw-in groove; Strut and draw-in groove are structure as a whole; Interior composite pipe periphery axially whenever is spaced a distance the strut more than three is set, and on the composite pipe, said deck was the semi-cylindrical hill that circumferentially disposes along outer composite pipe inner headed face in the strut more than three evenly was fixed on along interior composite pipe periphery; Said draw-in groove is a semi-circular recesses, and deck and draw-in groove are complementary.Owing to adopted the channel structure of outer composite pipe and interior composite pipe, make two kinds of different fluids or powder in pipeline, to transmit simultaneously, practiced thrift place and cost of production, improved efficient.Owing to adopted the rubber-like positioning device, interior composite pipe can directly be inserted in outer composite pipe secure fixation, can pull out along the cover Inbound again, and composite pipe is very convenient with the connection replacement of outer composite pipe in making.
Strut according to the invention and deck adopt stainless steel material to process.
Angle between strut according to the invention and the interior composite pipe central shaft is 45 degree and has elasticity.
Complex coating according to the invention adopts the stainless steel material roll extrusion to be composited.
The present invention is simple for structure rationally can to carry two kinds of different mediums simultaneously, and cost is low, and is effective.
