Abstract
The utility model relates to a steel pipe reinforced compound pipe, particularly a steel-plastic compound pipe. The steel pipe reinforced compound pipe is composed of three layers, wherein an internal layer is a plastic pipe, and a middle layer is a steel pipe; external threads are arranged on the excircles of the steel pipes at both ends of the compound pipe; both ends of the compound pipe are provided with special joints; grooves are fixed on the excircles of the joints; the inside diameters of the back parts of the joints are provided with internal threads; the internal threads of the joints and the external threads on the excircles of the steel pipes at both ends of the compound pipes are screwed together; the end head of the plastic pipe of the internal layer is provided with an outward flanged edge; one surface of the flanged edge is abutted on the end surfaces of the steel pipes; the other edge of the flanged edge is abutted on a step formed by that the inner diameters of the joints change. The steel pipe reinforced compound pipe has the advantages that the joints are arranged independently, connection between the joints and pipes is reliable, the tensile strength is large, the seal is good to make connection between pipes and pipes convenient and quick, the steel pipe reinforced compound pipe can be conveniently connected with other pipes and the construction is simple and the quality can be guaranteed in the construction of pipes.
Description
Technical field:
The utility model relates to a kind of steel pipe that carries jointing and strengthens composite pipe.
Background technique:
Placement between traditional mining conveyance conduit only limits to flange or injection moulding, cast member is connected, and between the steel-plastic composite pipe and and other delivery pipe between can be connected to become a technical problem reliably, easily.
Summary of the invention:
The purpose of this utility model provides a kind of steel pipe and strengthens composite pipe, and this pipe carries and connects reliable joint, makes things convenient for the connection between the tube and tube.
The purpose of this utility model realizes as follows: this steel pipe strengthens composite pipe and relates to steel-plastic composite pipe, the composite pipe body constitutes by three layers, internal and external layer is a plastic tube, the mesosphere is a steel pipe, on the steel pipe cylindrical of composite pipe two ends outside thread is arranged, at the composite pipe two ends special joint is arranged, joint rear portion internal diameter has internal thread, outside thread on the internal thread of joint and the composite pipe two ends steel pipe cylindrical screws together, makes between joint and the composite pipe reliably to be connected.
Sealing between composite pipe and the joint can adopt the method for smearing adhesive glue to solve, can also solve by following structure: there is outside flange internal layer plastic tube termination, the one side of flange leans against on the end face of steel pipe, the another side of flange leans against on the step of joint internal diameter varies formation, after screwing by screw thread between joint and the steel pipe, make flange be adjacent to joint and the steel pipe end face reaches seal action.
Have on the cylindrical of joint to fix and use groove, be used for link and fasten this groove to bear bigger axial tension.Certainly according to the difference of link, groove also can make annular boss into, serves the same role.
This steel pipe strengthens composite pipe and carries jointing, is connected reliably between joint and the pipe, and tensile strength is big, and good seal makes easy to connectly between the tube and tube and can be connected with other tubing is convenient fast, and construction simply also can be ensured the quality of products when setting up pipeline.
Description of drawings:
Accompanying drawing is the structural representation that the utility model steel pipe strengthens composite pipe.
Embodiment:
With reference to accompanying drawing, the steel pipe reinforced pipe mainly is made up of the joint at steel-plastic composite pipe body and two ends, composite pipe 1 constitutes by three layers, internal and external layer 3,2 is the anti-electrostatic fire retardant plastic tube, mesosphere 4 is a steel pipe, outer 2 plastic tubes in composite pipe 1 two ends remove one section, on steel pipe 4 cylindricals that expose, be processed with outside thread, at composite pipe 1 two ends special joint 6 is arranged, have fixing on the cylindrical of joint 6 with groove 7, the external diameter of joint 6 is identical with composite pipe 1 external diameter, the anterior big rear portion of the internal diameter of joint 6 is little, and big footpath forms a step with path conversion place, and joint 6 anterior internal diameters are identical with composite pipe 1 internal diameter, joint 6 rear portion internal diameters have internal thread, and the outside thread of the internal thread of joint 6 on composite pipe 1 two ends steel pipe 4 cylindricals is suitable and be tightened on.There is outside flange 5 internal layer 3 plastic tube terminations, the one side of flange 5 leans against on the end face of steel pipe 4, the another side of flange 5 leans against on the step of joint 6 internal diameter varies formation, in order to strengthen sealing effect, on this step surface, groove can be arranged, the O RunddichtringO is housed in groove, and pipe flange 5 passes through O RunddichtringO excellent sealing with joint 6 interior steps in making, thereby realizes the sealing between joint 6 and the composite pipe 1.
