Abstract
A polished pipe protection cap with a polishing end is used for protecting the end of petroleum casing pipe and various pipes. The polished pipe protection cap comprises a cap body which comprises an upper segment, a middle segment and a lower segment; wherein the diameters of the upper segment, the middle segment and the lower segment reduces gradually in segment. An outer wall of the cap body is provided with annular blades. An upper segment of the cap body is provided with a crown and constitutes the positioning end together with the upper segment of the cap body. The crown end is outwards overturned. Furthermore a transition platform is formed between the crown end and the upper segment of the cap body. The width of the transition platform is same with the thickness of the protected pipe. The internal diameters of the upper segment of the cap body and the protected pipe are same. The polished pipe protection cap with the polishing end is advantageous in that: because of the special design for the protection cap end, positioning for the crown and the upper segment of the cap body is realized for ensuring no matching eccentricity between the crown and a pipe-end bevel.
Description
Technical field
The utility model is mainly used in the protection of petroleum casing pipe and all kinds of tubing end, makes it in loading and unloading, transportation, avoid damage.
Background technology
Steel pipe very easily causes damage to pipe end in transportation, and for tube head is protected, generally at pipe end suit tin hat, former like product is two kinds of exterior buckle type and plug-ins, and the exterior buckle type tin hat is met vibrations, friction is prone to come off.Be prone to come off and the lifting problem though the plug-in tin hat has solved, tilt easily when installing, very easily cause the damage of tin hat in the handling process.
Summary of the invention
The utility model provides a kind of light pipe tin hat that has positioning end just in order to solve deficiency of the prior art, and it is realized when mounted locating voluntarily and is difficult for tilting, and tin hat is combined closely with steel pipe.
In order to achieve the above object, the technical scheme taked of the utility model is:
A kind of light pipe tin hat that has positioning end comprises the cap body, it is characterized in that, following three sections and indentation piecemeal were provided with annular blade at the external wall of cap during said cap body comprised, said cap body epimere is provided with crown and constitutes positioning end jointly with cap body epimere.
The above positioning end comprises crown and cap body epimere, turns up in said crown end, and and cap body epimere between form transition platform.
The width of the above transition platform is identical with the tube thickness of being protected, and said cap body epimere is interior through identical with the pipe of being protected.
The beneficial effect of the utility model is, because the particular design of tin hat end makes crown and cap body epimere realize the location, to guarantee that crown cooperates not eccentric with the pipe end groove.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1. cap body; 2. crown; 3. blade; 4. transition platform; 5. cap body epimere.
The specific embodiment
Can be known that by accompanying drawing 1 the utility model comprises cap body 1, following three sections and indentation piecemeal were provided with annular blade 3 at cap body 1 outer wall during said cap body 1 comprised, said cap body epimere 5 is provided with crown 2 and constitutes positioning ends jointly with cap body epimere 5.Turn up in said crown 2 ends, and and cap body epimere 5 between form transition platform 4.The width of the above transition platform 4 is identical with the tube thickness of being protected, and said cap body epimere 5 is interior through identical with the pipe of being protected, and has guaranteed that the utility model combines closely with the steel pipe of protection.
Should be noted that the described embodiment of the utility model only is its optimal way, only is conspicuous change to belonging to the utility model technical scheme, all should belong within the protection domain of the utility model.
