Abstract
The utility model relates to a plastic special liner pipe. The cross section of the liner pipe is non-circular, the liner pipe is a hollow pipe with a groove, after being installed, the liner pipe can be tightly clung on the inner wall of a steel pipe, to lead a transportation pipeline to not only have the advantages of no poison, vapidity, corrosion prevention and long service life of plastics such as polyethylene, etc., but also solve the problems that because of the corrosion and damage of the steel pipe, the service life is short, the water leakage often happens, and the water quality is influenced, etc. The plastic special liner pipes can be suitable to be used as the liner pipes of a great variety of pipelines such as a cement pipe, a stone surface pipe, and a cast iron pipe, etc., at the same time, the installation is simple, the cost is low, and the normal life and working of people is not influenced.
Description
Affiliated technical field
The utility model relates to a kind of plastic shaped internal lining pipe.
Technical background
Carry at present liquid to select steel pipe usually for use or be the plastic tube of raw material with plastics such as polyethylene, this delivery pipe of two types cuts both ways, though the steel pipe rerum natura is good, but because its poor corrosion resistance, life-span is short, often leaks a series of problems such as iron rust polluted water, though with plastics such as polyethylene is that this plastic tube of plastic tube of raw material is nontoxic, tasteless, decay resistance is strong, its some rerum natura is less than steel pipe.
Summary of the invention
The purpose of this utility model is to provide a kind of plastic shaped internal lining pipe, it can closely be fitted on the inwall of steel pipe, make delivery line not only have the advantage such as nontoxic, tasteless, corrosion-resistant long service life of plastics such as polyethylene, and it is short because of the life-span that corrosion failure causes to have solved steel pipe, often leak, influence problems such as water quality.
The utility model is that the technological scheme that its technical problem of solution is adopted is: a kind of plastic shaped internal lining pipe, internal lining pipe cross section are the non-circular hollow tubular that has groove; The internal lining pipe cross section is " U " shape hollow tubular; The internal lining pipe cross section is a conjuncted pair of kidney shape hollow tubular.
The beneficial effects of the utility model are that it can closely be affixed on the inwall of steel pipe after installing, make delivery line not only have the advantage such as nontoxic, tasteless, corrosion-resistant long service life of plastics such as polyethylene, and it is short because of the life-span that corrosion failure causes to have solved steel pipe, often leak, influence problems such as water quality.Also can do simultaneously multiple bore by the internal lining pipe of the various transfer line that install, a liner distance up to 200 meters about, construction is simple, saves the duration, expense is low, does not destroy a large amount of ground, has guaranteed people's normal life and work.This plastic shaped internal lining pipe can be used in cement pipe equally, stone facial canal, the bushing pipe of multiple pipeline such as cast iron tube.
Description of drawings
Be described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of " U " shape hollow tubular for the utility model cross section.
Fig. 2 is the structural representation of conjuncted pair of kidney shape hollow tubular for the utility model cross section.
Fig. 3 fills in the interior structural representation of steel pipe for cross section for the hollow tubular of " U " shape.
Fig. 4 fills in the interior structural representation of steel pipe for cross section for the hollow tubular of two kidney shapes.
Fig. 5 closely is fitted to the structural representation of steel pipe inwall for the utility model.
Embodiment
As shown in Figure 1 and Figure 2, internal lining pipe (1) cross section is " U " shape hollow tubular or conjuncted pair of kidney shape hollow tubular, and it can be on common plastics tubing production line, squeeze pipe tire outlet mould after, entering and add one group of special-shaped forming device before the typing cover and finish cooling and shaping.In the time of in it fills in steel pipe (2), examination cleans up steel pipe (2) inwall earlier, fills in the steel pipe (2), as shown in Figure 3, Figure 4 by oil thread rope then.Pressurizeed and expander with steam in the sealed at both ends back of profiled plastic internal lining pipe subsequently, internal lining pipe is attached on the steel pipe internal-surface, closely as shown in Figure 5.
Claims (3)
1, a kind of plastic shaped internal lining pipe is characterized in that described internal lining pipe cross section is the non-circular hollow tubular that has groove.
2, plastic shaped internal lining pipe according to claim 1 is characterized in that the internal lining pipe cross section is " U " shape hollow tubular.
3, plastic shaped internal lining pipe according to claim 1 is characterized in that the internal lining pipe cross section is a conjuncted pair of kidney shape hollow tubular.
