Consequently the utility model discloses high strength heat -preservation type feed pipe has safe and reliable, and the advantage of location is convenient for lay by long service life.
Description
Technical field
The utility model relates to a kind of high-strength insulation type supply pipe.
Background technique
PE pipe is widely used in non-pressure pipe, as fields such as water supply, combustion gas, blowdown and telecommunication cables.Because common PE supply pipe is for time buried, due to the increase of soil layer, rigidity deficiency, there is stress cracking in easy surface scratches, damaged, affects working life, and when laying, the defects such as inconvenience are located in existence.Therefore seek a kind of safe and reliable, long service life, the high-strength insulation type supply pipe being convenient to lay location is particularly important.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of safe and reliable, long service life, is convenient to the high-strength insulation type supply pipe laying location.
The purpose of this utility model is achieved in that
A kind of high-strength insulation type supply pipe, it comprises the supply pipe of horizontal arrangement, and the intermediate section of described supply pipe comprises internal layer thermal insulation layer, PE layer, steel screen layer and HDPE layer from inside to outside successively.Left section of described supply pipe and right section is provided with an annular groove, supply pipe outside two annular grooves comprises internal layer thermal insulation layer, PE layer, steel screen layer, HDPE layer and steel ring layer from inside to outside successively, the supply pipe at annular groove place comprises internal layer thermal insulation layer, PE layer, steel screen layer and HDPE layer from inside to outside successively, the HDPE layer at annular groove place is thinner than the thickness of the HDPE layer at supply pipe place, also be provided with three stiffening ribs be evenly arranged in described supply pipe, three stiffening ribs connect from supply pipe center to inner tubal wall.
Compared with prior art, the beneficial effects of the utility model are:
The utility model, due to fixed block load-bearing when laying, decreases supply pipe self stressed, and extend supply pipe working life, fixed block is Hexagon, not easily rotates, good positioning effect.Therefore the utility model high-strength insulation type supply pipe has safe and reliable, long service life, is convenient to the advantage of laying location.
