Abstract
The utility model discloses a tubular product, including steel body, be close to be equipped with the spacing block on the pipe inner wall of body tip, body between the spacing block and spacing block internal surface enclose to close and form a sealing region, the body tip forms free region with the spacing block surface, body surface and free region coating have epoxy protective layer. Forming the contact that sealing region can keep apart the inner wall and corrode the thing through the spacing block in the body, thoroughly avoiding corroding, epoxy protective layer can protect other naked tube part through the coating, the drawback of removing regular japanning from.
Description
Technical field
The utility model relates to a kind of tubing.
Background technique
As everyone knows, existing engineering pipe, pipe fitting in particular for iron skill is steel pipe, in the maintenance process in later stage, need that regular to carry out japanning to body antirust, body is hollow tubular, after first japanning, in maintenance process, inwall japanning is carried out very not easily to already installed body, but only to coated outside, inwall is easy to get rusty, from internal damage under comparatively moist or corrosion-prone environment.Prior art is badly in need of the good tubing of a kind of anticorrosion ability.
Summary of the invention
The purpose of this utility model is to overcome the defect existed in prior art, provides the tubing that a kind of anticorrosion ability is good.
For achieving the above object, the technical solution of the utility model there is provided a kind of tubing, comprise the body of steel, the inboard wall of tube body near described body end is provided with spacer, and the body between described spacer and spacer internal surface enclose formation sealing area; Body end and spacer outer surface form open area, and described outer surface of tube body and open area are coated with epoxy resin protective layer.In body, form by spacer the contact that sealing area can isolate inwall and erosion, thoroughly avoid corrosion, the body portion exposed to other can be protected by coating epoxy resin protective layer, remove the drawback of regular japanning from.
As preferably, described epoxy resin protective layer thickness is 1-2mm, and described epoxy resin protective layer is sprayfused coating.Such design can reduce costs under the prerequisite playing protection.
As preferably, described spacer is axially evenly equipped with multi-disc along pipe fitting.Such design is convenient to body and is cut as required, still has sealing area after cutting.
As preferably, described spacer thickness is 1-5mm, described spacer and body one-body molded.Such design is beneficial to the intensity and tightness that ensure body.
Advantage of the present utility model is with beneficial effect: in body, form sealing area by spacer and can isolate contacting of inwall and erosion; thoroughly avoid corrosion; the body portion exposed to other can be protected by coating epoxy resin protective layer, remove the drawback of regular japanning from.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, body; 2, spacer; 3, sealing area; 4, open area; 5, epoxy resin protective layer.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, a kind of tubing, comprises the body 1 of steel, and body 1 inwall near described body 1 end is provided with spacer 2, and the body 1 between described spacer 2 and spacer 2 internal surface enclose formation sealing area 3; Body 1 end and spacer 2 outer surface form open area 4, and described body 1 outer surface and open area 4 are coated with epoxy resin protective layer 5.
Described epoxy resin protective layer 5 thickness is 1-2mm, and described epoxy resin protective layer 5 is sprayfused coating.
Described spacer 2 is axially evenly equipped with multi-disc along pipe fitting.
Described spacer 2 thickness is 1-5mm, and described spacer 2 is one-body molded with body 1.
Make time, the spacer 2 in body 1 can directly arrange with the open end of body 1 near, then carrying out the spraying of epoxy resin protective layer 5, is the mode of the body 1 to fixed length like this; If body 1 indefinite length, just by uniform along axis for spacer 2, cuts during use as required, and then spray body 1 outer wall and open area 4.Before spraying, need smooth for body 1 surface finish, and clean up post-drying.
Epoxy resin has excellent corrosion resistance, adhesion and wear-resisting property, effectively resists the corrosion of acidic materials, simultaneously long service life, saves the troublesome operation of regularly japanning.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing from the front lower of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (4)
1. a tubing, is characterized in that: the body comprising steel, and the inboard wall of tube body near described body end is provided with spacer, and the body between described spacer and spacer internal surface enclose formation sealing area; Body end and spacer outer surface form open area, and described outer surface of tube body and open area are coated with epoxy resin protective layer.
