Abstract
The utility model provides a duct replacing and striking nipple joint device. The device comprises a pile pipe, process steps, a pile tongue and a lifting lug, wherein the lifting lug is arranged at one end of the pile pipe, and the process steps are arranged at the other end of the pile pipe; the pile tongue is arranged at the tail end of the process steps; the pile pipe, the process steps and the pile tongue adopt an integral structure; the diameter of the pile pipe is the same as that of a water barrier pipe; the diameter of the pile tongue is slightly smaller than that of the water barrier pipe; the angle of the inclined plane of the pile tongue is 60 degrees; two process steps are arranged between the pile tongue and the pile pipe, and the dimension of the outer diameter of each process step is determined by the associated dimension of the female joint of the water barrier pipe and is mainly matched with the female joint of the water barrier pipe; the outer diameter of the process step is adaptable to the female joint of the water barrier pipe. The device has the advantages of simple structure and convenience in operation.
Description
Technical field
The utility model relates to a kind of mechanical device, and device is beaten in replacing of especially a kind of ocean riser pipe operation.
Background technology
Marine petroleum development is in recent years day by day flourishing, and along with scientific and technical development, offshore oil drilling is already in full swing.According to marine site difference, offshore drilling riser pipe form of structure is not identical yet, but all marine drillings all need top layer conduit to protect, and prevents the operation impact that marine climate (stormy waves, undercurrent, morning and evening tides etc.) and seawater bring.So carry out again offshore drilling work after will first playing riser pipe.Riser pipe relies on linkage and pin and box sub to link together by many joint marine risers, different jointing forms, the mode of going into the well is also different, when with piling formula riser pipe, when in the process that marine riser is declining because buoyancy or other reasons cannot decline by conducting oneself with dignity time, just need to apply a downward pressure to marine riser.If directly masterpiece is used in riser box, be easy to cause band female joint distortion damaged, or the screw thread distortion of joint the inside cannot screw and coordinate with male joint; If exerted pressure on joint with cushion block pad, no matter be to have significant limitation cushion block manufacture craft or from construction equipment.Cushion block cannot meet construction requirement.
Utility model content
The purpose of this utility model is to avoid the deficiencies in the prior art and provides a kind of conduit for beating pipe nipple apparatus.
The technical solution of the utility model is: conduit is for beating pipe nipple apparatus, comprise pile pipe, technique step, stake tongue, hanger, one end of pile pipe is provided with hanger, and other one end is provided with technique step, the tail end of technique step is a tongue, and pile pipe, technique step, stake tongue are structure as a whole.
Described pile pipe is identical with riser pipe caliber.
Described stake tongue diameter is slightly less than riser pipe caliber.
Described stake tongue bevel angle is 60 °.
Technique step between described stake tongue and pile pipe has twice, and outside dimension is determined according to riser pipe female joint relative dimensions, mainly coordinated riser pipe female joint.
Described technique outer diameter of step and riser pipe female joint adapt.
Compared with prior art, the utility model has the advantages that: simple in structure, easy to operate.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1 is hanger; 2 is pile pipe; 3 is technique step; 4 is stake tongue.
Detailed description of the invention
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Conduit, for beating pipe nipple apparatus, comprises pile pipe 2, technique step 3, stake tongue 4, hanger 1, and one end of pile pipe 2 is provided with hanger 1, and other one end is provided with technique step 3, and the tail end of technique step 3 is tongues 4, and pile pipe 2, technique step 3, stake tongue 4 are structure as a whole.
Described pile pipe 2 is identical with riser pipe caliber.
Described stake tongue 4 diameters are slightly less than riser pipe caliber.
Described stake tongue 4 bevel angles are 60 °.
Technique step 3 between described stake tongue 4 and pile pipe 2 has twice, and outside dimension is determined according to riser pipe female joint relative dimensions, mainly coordinated riser pipe female joint.
Described technique step 3 external diameters and riser pipe female joint adapt.
When operation, conduit is installed on pile driver for beating pipe nipple, hanger 1 use wire rope and pile driver are fixed together, when downcomer, pile driver is installed conduit for beating in the female joint of stake tongue 4 partial insertion riser pipes of pipe nipple, technique step 3 is just in time stuck in female joint end face and interior step, and does not injure female joint internal whorl.Replace dozen pipe nipple that power is delivered on riser pipe by conduit, complete the effect of transferring conduit.
