Abstract
The utility model discloses a tubular product with annular groove and spiral groove, including body made of iron, the last baffler that is equipped with of pipe inner wall, body and separation hoarding between the baffler close sealing region of formation, the body tip forms open space with the baffler, be equipped with rather than coaxial annular groove on the body outer wall, the annular groove is along the axial equipartition, still is equipped with spiral groove around the body outer wall, the body outer wall has the epoxy layer with the coating of open space, and epoxy fills on the layer in annular groove and spiral groove. Forming the contact that sealing region can keep apart the inner wall and corrode the thing through the division board in the body, thoroughly avoiding corroding, can protect other naked tube part through coating epoxy layer, the drawback of removing regular japanning from increases the recess at the body outer wall and can increase the area that adheres to on epoxy layer, prevents that it breaks away from.
Description
Technical field
The utility model relates to a kind of tubing being provided with annular groove and helical groove.
Background technology
As everyone knows, existing engineering pipe, body in particular for iron skill is iron pipe, in the maintenance process in later stage, need that regular to carry out japanning to body antirust, body is hollow pipe, 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 annular groove and helical groove, comprise body made of iron, described inboard wall of tube body is provided with baffler, and the body between described baffler and baffler enclose formation sealing area; Body end and baffler form open space; Tube wall is provided with the annular groove coaxial with it, described annular groove is uniform vertically, also be provided with helical groove around tube wall, described tube wall and open space are coated with epoxy resin layer, and epoxy resin layer is filled in annular groove and helical groove.In body, the contact that sealing area can isolate inwall and erosion is formed by division board; thoroughly avoid corrosion; can the body portion exposed to other be protected by coating epoxy resin layer; remove the drawback of regular japanning from; increase at tube wall the bond area that groove can increase epoxy resin layer, prevent it from departing from.
As preferably, described helical groove and annular groove are major arc groove, and described annular groove and the staggered position of helical groove form staggered groove, and epoxy resin layer is filled in staggered groove.Such design can increase the bond area of epoxy resin layer further, prevents it from departing from.
As preferably, described baffler is axially evenly equipped with multi-disc along body.Such design is convenient to body and is cut as required, still has sealing area after cutting.
As preferably, described epoxy resin layer thickness is 2-6mm, and described epoxy resin 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 sealing area by division board and can isolate contacting of inwall and erosion; thoroughly avoid corrosion; can the body portion exposed to other be protected by coating epoxy resin layer; remove the drawback of regular japanning from; increase at tube wall the bond area that groove can increase epoxy resin layer, prevent it from departing from.

Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention 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 annular groove and helical groove, comprises body 1 made of iron, and described body 1 inwall is provided with baffler 2, and the body 1 between described baffler 2 and baffler 2 enclose formation sealing area 3; Body 1 end and baffler 2 form open space 4; Body 1 outer wall is provided with the annular groove 6 coaxial with it, described annular groove 6 is uniform vertically, also be provided with helical groove 7 around body 1 outer wall, described body 1 outer wall and open space 4 are coated with epoxy resin layer 5, and epoxy resin layer 5 is filled in annular groove 6 and helical groove 7.
Described helical groove 7 and annular groove 6 are major arc groove, and the position that described annular groove 6 and helical groove 7 interlock forms staggered groove 8, and epoxy resin layer 5 is filled in staggered groove 8.
Described baffler 2 is axially evenly equipped with multi-disc along body 1.
Described epoxy resin layer 5 thickness is 2-6mm, and described epoxy resin layer 5 is dip-coating layer.
When making, the division board 2 in body 1 can directly be arranged near the open end of body 1, then carries out the dip-coating of epoxy resin 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 division board 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 annular groove 6, helical groove 7 and staggered groove 8 before dip-coating.Preferably annular groove 6, helical groove 7 and staggered groove 8 are arranged identical deeply.
Epoxy resin has excellent corrosion resistance, adhesive force and anti-wear performance, effectively resists the corrosion of acidic materials, simultaneously long service life, saves the troublesome operation of regularly japanning.
The above is only preferred embodiment 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.
