Description
Technical field
The utility model relates to a kind of conveyance conduit field, particularly to a kind of FRP compound pipeline complex pipeline.
Background technology
Use of the structure sheaf of existing compound pipeline complex pipeline carries out pipe strengthening with the wrong mesh skeleton around shaping of high-tensile steel wires for reinforcement more, under operating pressure is gradually increased, internal pipe pressure is also increasing therewith, when internal pipe pressure is excessive, stainless steel inner lining reaches complete yield, and pipeline does not possess further bearing capacity, and the stress in fiberglass shell reaches break limit, cause pipeline damage, it is impossible to use；Simultaneously, real fluid in nature is all to have viscosity, frictional force can be produced because of relative motion between fluid layer between fluid particle and revolt the character of relative motion, a part of mechanical energy of fluid will irreversibly be converted into heat energy, and make fluid flowing many complicated phenomenons occur, and existing compound pipeline complex pipeline is circle, can not stop or reduce its stickiness stress in liquid or gas flow, increasing pressure drag, reducing flowing velocity, operating efficiency also decreases.
Utility model content
The purpose of this utility model be to provide a kind of safe, reliable, environmentally friendly, there is higher bearing overload capacity and have the FRP compound pipeline complex pipeline of bigger safety coefficient.
To achieve these goals, the technical solution of the utility model is:
A kind of FRP compound pipeline complex pipeline; including pipeline and the connection dish being arranged on pipe ends; described pipeline includes three layers; it is followed successively by wear-resistant liner layer, structure sheaf and external protection from inside to outside; described wear-resistant liner layer is stainless steel inner lining; wear-resistant liner layer is smooth streamlined in front round metacone, surface; between wear-resistant liner layer and structure sheaf, steel wire is set; described steel wire is fitted in the outer surface of wear-resistant liner layer; it is respectively provided with through hole in the transverse steel wire of steel wire two ends interface; fit steel wire in described through hole, is matched in clearance between through hole and steel wire；Described structure sheaf is seamless steel pipe, and described external protection is the anticorrosion enamelled coating smeared on structure sheaf.
Further, described connection dish arranges connecting hole.
Further, the internal diameter of described connection dish is more than the external diameter of pipeline.
The utility model is a kind of FRP compound pipeline complex pipeline, and it has the beneficial effect that
The utility model compound pipeline complex pipeline is outside rounded, does not affect and installs and uses, and the wear-resistant liner layer within compound pipeline complex pipeline uses streamlined replacement circle of the prior art, air drag will not be increased, flow separation can be made to reduce to relatively low, reduce pressure drag, increase flowing velocity；Outer wall laminating one steel wire of wear-resistant liner layer, plays the effect of protection so that it is be unlikely to deform；The two ends of steel wire are tentatively fixed by steel wire, and steel wire is linked in the inside of steel wire through hole, do not have protruding phenomenon, make the surface of pipeline still smooth, facilitate the construction of structure sheaf；Structure sheaf is seamless steel pipe, makes the bearing capacity of compound pipeline complex pipeline entirety and anti-pressure ability become big, is difficult to surrender, ruptures, the service life of increase compound pipeline complex pipeline, when using in as engineerings such as desulfurization slurry systems, and not easy to leak and corrosion, increase its security.
