Abstract
The utility model relates to a weldable plastic-coated steel-plastic pipe, belonging to the technical field of machines. The weldable plastic-coated steel-plastic pipe comprises a base pipe and a plastic coating layer and is structurally characterized in that a stainless steel lining pipe is arranged on the edge of the base pipe and the plastic coating layer is arranged outside the base pipe and the stainless steel lining pipe. The utility model has the advantages that the structural design is reasonable, the service life is long, the pipe is not apt to be oxidized and corroded and the pipe is weldable.
Description
Technical field
The utility model relates to a kind of plastic-steel that is coated with that can weld and moulds pipe, belongs to field of mechanical technique.
Background technique
Plastic coated composite steel pipe is widely used in plumbing, fire-fighting, colliery, oil transportation gas transmission, chemical industry and peculiar to vessel etc., but in application between steel pipe and the steel pipe best installation method be welding.The prior art plastic coated composite steel pipe is in installation, the installation method of plastic coated composite steel pipe is that silk mouthful connection, groove connect and be connected with flange, its defective is: the pipe internal pressure is big, causes liquids and gases outwards to ooze out from pipe internal sealing plug, groove and flange, causes the joint corrosion; The joint of outdoor pipe contacts the meeting oxidation with air; Pipe laying joint, ground is subjected to the acid or alkaline long-term corrosion of soil and destroys, and has a strong impact on the working life of pipe network, does not satisfy desirable using effect.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of reasonable in design, and long service life is difficult for the plastic-steel that is coated with that can weld oxidized and corrosion and moulds pipe.
It is that this plastic-steel that is coated with that can weld is moulded pipe that the utility model solves the problems of the technologies described above the technological scheme that is adopted, comprise parent tube and plastic coating, its structural feature is: the edge of described parent tube is provided with the stainless steel bushing pipe, and plastic coating is arranged on outside parent tube and the stainless steel bushing pipe.
The length of stainless steel bushing pipe described in the utility model is 10cm.
Method and parent tube that stainless steel bushing pipe described in the utility model is used double screw hot rolling are combined with each other.
Stainless steel bushing pipe described in the utility model is arranged on the inboard and edge surface at parent tube edge.
The utility model is after welding, and the position of soldering point is provided with epoxy coating and repairs glue.
The utility model is compared with prior art and is had the following advantages and effect: 1, owing to be provided with thin stainless steel bushing pipe in the position of the edge of parent tube 10cm, can realize connecting with the method for welding, leakproof, the anti-corrosion capability of tubing have so just been improved greatly, improved working life, can reach more than 50 years.2, owing to used the high-performance epoxy resin coating after the welding and repair glue and connect the parent tube external coating, had therefore that outward appearance is tough and tensile, durable, scratch resistance, high impact properties, high heat-resisting, clean health, have no side effect, heavy corrosion-resistant premium properties.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation after welding.
Embodiment
Below in conjunction with embodiment the utility model is described in further detail, following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment 1: as shown in Figure 1, 2, present embodiment is made up of parent tube 1, stainless steel bushing pipe 2, plastic coating 3, parent tube 1 is used the Ordinary Steel pipe, in 1 two ends of parent tube, the thin-wall stainless steel bushing pipe 2 of the compound 10cm length of roll extrusion, the port flange, it is firmly compound that parent tube 1 and stainless steel bushing pipe 2 are used the method for double screw hot rolling.Parent tube 1 inside and outside wall scribbles plastic coating 3, and plastic coating 3 high temperature and high speeds are sprayed on inside and outside the parent tube 1.Plastic coating 3 and stainless steel bushing pipe 2 have the overlap joint of 4cm, and the plastic-steel that is coated with that formation can be welded is moulded pipe.After being coated with plastic-steel and moulding pipe welding, use high performance epoxy coating and repair glue 5 and connect and cover at soldering point 4, design of the present utility model and innovation have increased fastness and aesthetics, have prolonged the working life of pipe network.
Be coated with plastic-steel and mould pipe in the process of being welded to connect, can be with stainless steel electrode that the welding of stainless steel bushing pipe 2 parts is fixing earlier, after parent tube 1 welding is fixing, it is big to prevent to manage internal pressure, liquids and gases and soldering opening corrosion, the innovation of technology has increased the antiseptic property of composite pipe greatly, reaches service life more than 50 years, accomplished really and the same life-span of building that the innovation of technology reaches advanced international level.
In addition, need to prove, the specific embodiment described in this specification, its zero, the shape of parts, institute's title of being named etc. can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of the utility model patent according to the utility model patent.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount the defined scope of these claims, all should belong to protection domain of the present utility model.
