Abstract
The utility model relates to a lining plastic clad pipe. A plastic pipe is inserted into a metal pipe, to form a pipe-in-pipe composite structure by adopting the characteristics that the mechanical strength of a rigid pipeline is high, the plastic pipe is corrosion resistant and oxidation resistant, the heat insulation and heat preservation performance is good, and the pipes are fire proof and pollution-free, thus not only solving the outlet of the overstock of the galvanized pipes, but also effectively improving the comprehensive characteristic and the service life of a water supply plastic pipe. The utility model is characterized in that the inner wall of the rigid pipeline and the outer wall of the plastic pipeline are tightly clung to form the clad pipe, the ratio of wall thickness of the rigid pipeline and the plastic pipeline is 1: 01 to 22, the rigid pipeline comprises a cold coating steel pipe, a hot dip coating steel pipe, a copper pipe, and a cast iron pipe or a glass steel pipe; the plastic pipeline comprises a high density polypropylene pipe or a tri-polypropylene pipe.
Description
Affiliated field: the utility model relates to waterworks structure tubing technical field, especially a kind of lining plastic composited pipe.
Background technique: existing all water supply-drainage disciplines all are to be standard with the Coating Steel Pipe from teaching, design, construction, and construction team has possessed ripe galvanized pipe construction technology and special device.At present, owing to galvanized pipe is expressly forbidden being used for the feedwater field by the Ministry of Construction, thereby cause a large amount of of galvanized pipe to overstock.On the other hand, thermal expansion can occur during the plastic pipes for water delivering hot water, the life-span is shorter relatively, in secondary decoration or expose the equal sensitive for damages of plastic tube of arrangement.
Summary of the invention: at the deficiency of above-mentioned prior art existence, the utility model proposes a kind of lining plastic composited pipe, exactly plastic tube is inserted in the metal tube, utilize the rigid conduit mechanical strength high and plastic tube is corrosion-resistant, anti-oxidant, heat-insulation and heat-preservation is good, fire prevention, free of contamination characteristic, the composite structure of forming pipe-in-pipe, both solve the outlet of overstocked galvanized pipe, effectively improved the overall characteristic and the working life of plastic pipes for water again.
Its structure characteristic of the lining plastic composited pipe that the utility model provides is: rigid conduit inwall and plastic pipe outer wall are close to the formation composite pipe, and the ratio of rigid conduit and the wall thickness of plastic pipe is 1: 0.1～2.2.
Described rigid conduit comprises hot and cold steel plating pipe, copper pipe, cast iron tube or Glass Steel Tube; Plastic pipe comprises high density poly propylene pipe HDPE or three type polypropylene tube PP-R.
Proposition of the present utility model makes at present that all are the construction team of object, the ripe galvanized pipe construction technology that they possess and the special device that has with the Coating Steel Pipe, can continue to continue to use, and has also increased employment.
Description of drawings: Fig. 1 is a schematic representation of the present utility model.
Embodiment: among the figure, the 1st, galvanized pipe, the 2nd, plastic tube.
During making, to directly insert in the galvanized pipe behind high density poly propylene pipe (HDPE) or the effective special-purpose size reducing machine undergauge of three type polypropylene (PP-R), after treating a period of time, under himself elastoplasticity effect, form the steel-plastic composite pipe of being close to the steel pipe inwall by expanding.
There is 1: 0.1 between the wall thickness of steel pipe and plastic tube in the composite pipe～2.2 adjustable extent.When steel pipe was extra strong pipe, pressure rating was big, only needed lining go into thin plastic tube, made that the water source is not contaminated to get final product; When the thin thickness of steel pipe, its pressure rating is less, then need serve as a contrast into thicker plastic tube with the boost pressure grade; When as hot-water line, if water temperature is too high, the plastic tube that needs lining to go into thickening has stronger heat insulation effect and higher pressure rating to guarantee it; When being used for chemical industry, because temperature is too high and corrosion is stronger, then need serve as a contrast the plastic tube that differs about two times can ensure the quality of products.
The product mechanical strength height that the utility model provides, corrosion-resistant, anti-oxidant, heat-insulation and heat-preservation, fire prevention, pollution-free, and easy for installation as traditional galvanized pipe, not flexible, reach 70 years working life, will become the leading tubing in industry from now on and the civil building.
