Abstract
The utility model discloses a tubular product with axial notch and annular groove, 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 confined space, the body tip forms open space with the spacing block surface, be equipped with the axial notch on the body outer wall, the axial notch still is equipped with on the body outer wall rather than coaxial annular groove along the axial extension and around the body equipartition, the axial equipartition is followed to the annular groove, the body outer wall has epoxy protective layer with the coating of open space, and the epoxy protective coating is filled in axial notch and annular groove. Forming the contact that confined space 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.
Description
Technical field
The utility model relates to a kind of tubing being provided with axial notch and annular groove.
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 being provided with axial notch and annular groove, comprise the body of steel, 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 seal space; Body end and spacer outer surface form open space; Described tube wall is provided with axial notch; described axial notch extends and uniform around body vertically; tube wall is also provided with the annular groove coaxial with it; described annular groove is uniform vertically; described tube wall and open space are coated with epoxy resin protective layer, and epoxy resin protective coat is filled in axial notch and annular groove.In body, the contact that seal space can isolate inwall and erosion is formed by spacer; thoroughly avoid corrosion; can the body portion exposed to other be protected by coating epoxy resin protective layer; remove the drawback of regular japanning from; increase at tube wall the bond area that groove can increase epoxy resin protective layer, prevent it from departing from.
As preferably, described axial notch and the staggered position of annular groove form staggered groove, and epoxy resin protective coat is filled in staggered groove.Such design can increase the bond area of epoxy resin protective layer further, prevents it from departing from.
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 seal space after cutting.
As preferably, described epoxy resin protective layer thickness is 2-3mm, and described epoxy resin protective layer is dip-coating layer.Such design can reduce costs under the prerequisite playing protection.
Advantage of the present utility model is with beneficial effect: in body, form seal space by spacer and can isolate contacting of inwall and erosion; thoroughly avoid corrosion; can the body portion exposed to other be protected by coating epoxy resin protective layer; remove the drawback of regular japanning from; increase at tube wall the bond area that groove can increase epoxy resin protective layer, prevent it from departing from.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is pipe structure schematic diagram before coating.
In figure: 1, body; 2, spacer; 3, seal space; 4, open space; 5, epoxy resin protective layer; 6, axial notch; 7, annular groove; 8, staggered groove.
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 1-2, a kind of tubing being provided with axial notch and annular groove, comprise the body 1 of steel, 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 seal space 3; Body 1 end and spacer 2 outer surface form open space 4; Described body 1 outer wall is provided with axial notch 6; described axial notch 6 extends and uniform around body 1 vertically; body 1 outer wall is also provided with the annular groove 7 coaxial with it; described annular groove 7 is uniform vertically; described body 1 outer wall and open space 4 are coated with epoxy resin protective layer 5, and epoxy resin protective coat is filled in axial notch 6 and annular groove 7.
The position that described axial notch 6 and annular groove 7 interlock forms staggered groove 8, and epoxy resin protective coat is filled in staggered groove 8.
Described spacer 2 is axially evenly equipped with multi-disc along pipe fitting.
Described epoxy resin protective layer 5 thickness is 2-3mm, and described epoxy resin protective layer 5 is dip-coating layer.
When making, the spacer 2 in body 1 can directly be arranged near the open end of body 1, then carries out the dip-coating 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 dip-coating body 1 outer wall and open space 4.
Need to carry out sonic cleaning thoroughly to body 1 outer wall and axial notch 6, annular groove 7 and staggered groove 8 before dip-coating.Preferably the groove depth of axial notch 6, annular groove 7 and staggered groove 8 is arranged identical.
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.
