Abstract
The utility model belongs to a protective device for protecting threads on the steel pipe end in the storage, transportation, loading and unloading process in a petroleum industry. The utility model has the technical scheme that the pipe end thread protective sleeve includes a main body; one end of the main body is provided with threads and is a screwing end; the other end of the main body is a buffer end; and the screwing end and the buffer end are integrally arranged. The pipe end thread protective sleeve is characterized in that and the height at the buffer end is greater or equal to 50mm, greater than or equal to two times of the average thickness of the side wall on the buffer end and greater or equal to 0.2 time of the diameter of the upper end face on the buffer end. Owing to employing the above mentioned scheme, the utility model overcomes the shortcoming in prior art and provides a novel pipe end thread protective sleeve which well protects the pipe end face, has good buffer effect and light weight, saves material, is environmentally friendly and convenient to recycle.
Description
Technical field
The utility model belongs to petroleum industry is used to protect the pipe end screw thread in accumulating, handling process fender guard.
Background technology
The pipe thread fender guard has, and overall plastic (full elastomeric material) and steel are moulded (the built-in hole pattern metal cylinder of elastomeric material) two classes.Bear jolt capacity for improving fender guard, developed steel bushing in recent years, the fender guard of the embedding lining structure that plastic body press-fits after embarking on journey has separately improved the ability of fender guard impact resistance greatly, more effectively protects the pipe end screw thread.But this embedding lining structure fender guard invar, the plastics swell-shrinking property differs greatly, and when temperature traverse is big, steel bushing in use takes place sometimes with skidding between the plastics elastic body, and the phenomenon that gets loose can not screw out fender guard smoothly on the pipe end screw thread; The fender guard of this structure in addition, with steel bushing strong after, make and directly utilize the fender guard inner chamber to carry out lifting operation to become possibility, thereby also may cause the pipe end distortion and damage pipe thread; Last existing fender guard dismounting is pretty troublesome and can not well protect the end face of pipe end.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, the novel pipe thread protecting sleeve of provide that the fine protection pipe end of a kind of energy end face, good buffer effect, weight are little, saving in material and environmental protection being convenient to reclaim.
In order to realize above purpose; the utility model is by the following technical solutions: a kind of pipe thread protecting sleeve; include body; described body one end is provided with screw thread and is the end that spins; the other end is the buffering end; the described end that spins is wholely set with cushioning end, it is characterized in that: the height of described buffering end is held 0.2 times of upper surface diameter more than or equal to 50mm and more than or equal to the twice of the sidewall mean thickness that cushions end and more than or equal to buffering.
By adopting such scheme, when protecting sleeve is screwed in pipe end, well protected the pipe end end face, have good shock resistance, reach this product all properties index in the world fully.
In the utility model embodiment, the body of described pipe thread protecting sleeve is that non-metallic material is made, and the end of described buffering end is provided with groove; The inwall that is positioned at the buffering end of described body is provided with baffle plate, and this baffle plate and body are wholely set; The inwall that is positioned at the end that spins of described body is provided with baffle plate, and this baffle plate and body are wholely set, and described baffle plate becomes hollow shape between buffering end end face; The other end that is positioned at the end that spins of described buffering end becomes horn-like hatch frame.
Adopt such scheme; in lifting, can exert all one's strength and act on the protecting sleeve; well protected pipe end; adopt non-metallic material in addition; make this product weight little, saving in material is convenient to on-site installation and dismounting; the metallic contact with the responsive body of special grade of steel is avoided in the overall plastic design of this product, can reach the high strength of compound type again.
Below in conjunction with accompanying drawing the utility model is described in further detail
