Description
Technical field
The utility model belongs to pipeline field, more particularly to the outer plastic-coated lining plastic that a kind of both ends are covered with stainless steel protection
Pipe.
Background technology
Steel-plastics composite pipe is because it has the two-fold advantage of plastics and steel concurrently, while ensuring to convey the health of water quality, also
Larger discharge pressure can be born, individually steel pipe or plastic tube problem encountered are used so as to solve.At present, steel modeling is multiple
Close pipe and have become the rapid field of pressure pipeline industry development.
The end of plastics lined pipe is directly connected using clamp in the prior art, and sealing rubber circle is co-axially mounted inside clamp, is ensured
The leakproofness of pipeline junction, but in use, due to prolonged practical, the junction of pipeline is by water repeatedly
Stream washes away, and easily makes the separated situation in part occurs between lining plastic pipe and steel pipe, causes pipe end part to be cracked, influence pipe
Road service life.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, there is provided a kind of structure is novel, prevents pipe end
The outer plastic-coated lining plastic pipe that destroyed both ends are covered with stainless steel protection.
The technical scheme adopted by the utility model is that：
The outer plastic-coated lining plastic pipe that a kind of both ends are covered with stainless steel protection, including steel pipe tube body, the lining plastic in steel pipe body
Expects pipe, coats epoxy powder layer in steel pipe tube wall, indent is coaxially formed with the both ends of steel pipe tube wall, in steel pipe tube body
End, is co-axially mounted end cap, and the end cap includes one end pipe neck and the radially outer integral baffle ring of tube end, pipe neck
The coaxial inner edge for being inlaid in inner lining plastic tube in steel pipe body, the outer rim of baffle ring extend to steel pipe tube body and coating epoxy powder layer
Connecting sewing sentence outer, the connecting sewing between steel pipe tube body, plastic pipe layer, coating epoxy powder layer can be blocked.
Moreover, on pipe neck side wall corresponding indent position, be integrally formed with indent groove, the indent of steel pipe tube body is same
Axis is inlaid in indent groove.
Moreover, the coating epoxy powder layer at indent thickens the thickening layer of 1mm.
The advantages of the utility model and good effect are：
The both ends that the application provides are coated with epoxy powder with the outer plastic-coated lining plastic outer tube layer that stainless steel protection covers, can
Effectively prevent the erosion of pipeline from degenerating, anti-corrosion effect is fabulous, and the outer plastic-coated of lining plastic can ensure the anti-corrosion corrosion of steel pipe inside and outside
Effect, extends the practical time limit of pipeline.
The both ends end of plastics lined pipe provided by the utility model is co-axially mounted an end cap, and end cap includes one end pipe neck
With the radially outer integral baffle ring of tube end, neck coaxial package, can be with protective conduit junction indent portion inside plastics lined pipe
The inner lining plastic tube divided, the baffle ring being integrally formed with are used for the connection for protecting the steel pipe tube body and plastic pipe layer of plastics lined pipe connection end
Seam, prevents water from corroding pipeline from this gap, avoids leakage of pipeline etc..
The end cap for the plastics lined pipe that the application provides is stainless steel, is not afraid of and collides with, and water can be stopped to steel pipe and modeling layer
The impact of bonding place, which avoids coming unglued, to prolong the service life, and can have a good protective effect to tube end, and cost is not high, peace
Fill very convenient, be carried out at the same time with the indent process of plastics lined pipe, operation is very convenient.

Fig. 3 is the outer plastic-coated lining plastic pipe with thickening layer.
Embodiment
With reference to embodiment, following embodiments, which are illustrative, are not limited is further illustrated to the utility model
, it is impossible to limit the scope of protection of the utility model with following embodiments.
The outer plastic-coated lining plastic pipe that a kind of both ends are covered with stainless steel protection, including steel pipe tube body 4, the lining plastic in steel pipe body
Expects pipe 5,
In steel pipe tube wall coating epoxy powder layer 3, indent 2 is coaxially formed with the both ends of steel pipe tube wall, in steel
Pipe tube body end, is co-axially mounted end cap, and the end cap includes one end pipe neck 6 and the radially outer integral baffle ring 1 of tube end,
Pipe neck is coaxially inlaid in the inner edge of inner lining plastic tube in steel pipe body, and the outer rim of baffle ring extends to steel pipe tube body and applies shroud
Outside the connecting sewing of oxygen powder bed is sentenced, the connecting sewing between steel pipe tube body, plastic pipe layer, coating epoxy powder layer can be blocked.
The position of corresponding indent on pipe neck side wall, is integrally formed with indent groove, and the indent of steel pipe tube body is coaxially inlaid in indent
In groove.
Destruction of the connection card to outer layer coating epoxy powder layer, the coating epoxy powder layer at indent thicken in order to prevent
The thickening layer 7 of 1mm, for preventing the destruction of outer plastic-coated.
Neck coaxial package, can be with the plastic lining of protective conduit junction tank compartment inside plastics lined pipe in the application
Pipe, the baffle ring being integrally formed with are used to protect the steel pipe layer of plastics lined pipe connection end, plastic pipe layer, the connection for coating epoxy powder layer
Seam, prevents water from corroding pipeline from this gap, avoids leakage of pipeline etc..
