Description
Technical field
The invention belongs to pipeline production technical field, relate to a kind of corrugated tube, a kind of high rigidity steel band bellows.
Background technology
Rigidity is the external force value making object produce needed for unit deformation.Rigidity and the material character of object, geometry, limit
Boundary supports that situation and External Force Acting form are relevant.The elastic modelling quantity of material and modulus of shearing (see the mechanical property of material) are more
Greatly, then rigidity is the biggest.The rigidity (k) of one structure refers to the ability that elastomer resistance to deformation stretches.Computing formula: k=P/ δ P
Being the constant force acting on structure, δ is the deformation produced due to power.
Steel band bellows cry again steel band reinforced polyethylene spiral ripple pipe be a kind of with high density polyethylene (HDPE) (PE) as matrix
The winding structure pipe that (ectonexine) is compound with surface coating adhering resin steel band.Structural pipe wall is constituted by three layers: internal layer is one
Individual continuous real wall PE inner tube, is wound with (being " V " type with steel formability) annular wave steel strip reinforced body, at ripple outside inner tube
The external outer layer being compounded with polyethylene of shape steel strip reinforced, thus it is combined into the helical bellows of entirety.The elastic modelling quantity of steel is poly-
Nearly 200 times (elastic modelling quantity of carbon steel is at about 190000MPa) of ethylene, the advantage in conjunction with metal and plastics clearly reaches
The low consumed desired solution of high rigidity, it is possible to by the corrosion-resistant, wear-resistant of high rigidity, high intensity and the plastics of steel and pliability
Organically combine Deng good characteristic, advantage of both performance, make up both sides shortcoming, it is achieved high-performance and low cost
Unification.
Existing plastic corrugated pipe is a kind of plastic extruding forming, and a kind of plastics-production cannot be in view of ensureing to draw
Stretch intensity, elastic modelling quantity, ring stiffness again in view of tubing pliability.Therefore manufacturer is the most of poor quality when carrying is deposited
The easy compressive strain of product, compressive strain on car among transport of dispatching from the factory, workers carry does not note easily touching rotten.In project installation mistake
Do not note being easy to smash tubing, due to compressive load effect over and around, tubing after installation when journey backfills the cubic metre of earth and stone
Can't bear to bear deformation, or inwardly extrude, cause pumped (conveying) medium seepage in pipe, cause soil secondary pollution, owing to fluid media (medium) oozes
Leakage outflow, slowly corrodes embankment around tubing, makes embankment inanition around tubing cause the earthwork can't bear the heavy load, the most often occur
Road house collapse car crash accident.
Due to above reason, therefore it is badly in need of a kind of high intensity composite pipes of exploitation and not only can guarantee that pipe ring stiffness but also can guarantee that
Tubing pliability improves the safety of pipeline.
