Description
Technical field
The utility model relates to a kind of fixed connection apparatus of pipeline, especially relates to a kind of novel clamp device of grouted solid ocean platform standpipe.
Background technique
Usually, during the ocean platform production run, need to install new standpipe sometimes, in view of welding difficult quality guarantee under water, but the pipe clamp of folding is all used at newly-increased riser clip two ends, an end fixed riser, and an end is stuck on the jacket steel pipe.Because not welding, the riser clip of this normal mode can only be maintained fixed by the frictional force of rubber spacer and the pretightening force of clamping bolt, needs running check rubber spacer and clamping bolt, in case find wearing and tearing and loosening, need in time change or fastening.For related domain, its South Sea deep water platform, the length of every section standpipe suspended span is all very big, and under the ocean current long term, standpipe and riser clip can be subjected to very big cyclic loading.Wearing and tearing and loosening can take place in rubber spacer and clamping bolt gradually, change or fastening as untimely, and riser clip can slide or come off, and causes that standpipe rocks, even fracture, has influence on the platform ordinary production, even the initial ring environment pollution.
The model utility content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, a kind of being connected and fixed of maintenance that riser clip can be forever firm and jacket steel pipe that make is provided, needing to have avoided frequent conventional submarine inspection to clamp rubber spacer and clamping bolt, improve standpipe fixed mass and service time, thereby guaranteed the Safety performance of standpipe.
The utility model is achieved by following technical proposals:
The utility model is a kind of novel clamp device of grouted solid ocean platform standpipe, the supporting steel pipe that comprises an end and standpipe clip connected, the other end of described supporting steel pipe is connected with the location clip, described location clip is made of the cylinder-like structure that 2 semicircle steel plate make-ups and jacket steel pipe form a cavity, be used for the fill water mud layer in the described cavity, the outer wall of described semicircle steel plate is provided with grout hole and returns the slurry hole, described grout hole is welded with the short tube that is connected with the pump line that is in the milk, and the inwall of described semicircle steel plate is provided with shear key.
The periphery of described semicircle steel plate is provided with sealing joint strip.
The side of described semicircle steel plate is respectively arranged with bolt hole, and wherein a side flexibly connects by the d-axis steel pin, and the described bolt hole of opposite side is used for plugging together mutually with lock bolt.
Be provided with trigonometric form between the described bolt hole and strengthen gusset.
Described standpipe clip, supporting steel pipe and location clip are that high-strength shipbuilding section is made.
The outer surface of described standpipe clip, supporting steel pipe and location clip is provided with corrosion-inhibiting coating.
The beneficial effects of the utility model are:
1. the technical program adopts the location clip to be formed the characteristics of the cylinder-like structure of a cavity by 2 doughnut-shaped steel plate make-ups and jacket steel pipe, in cavity, can carry out the can of cement slurry, after cement slurry solidifies, can make location card hoop and jacket steel pipe permanent fixation, thereby make fixedlying connected of the firm maintenance of standpipe clip and standpipe, and then guaranteed the Security of standpipe, having solved conventional location down clip only depends on the frictional force of rubber ring to be fixed on the jacket steel pipe, under the long-term cyclic loading effect of ocean current, easy to wear and loosening problem.
2. the utility model apparatus cost is low, easy to use, can widely apply in the newly-built standpipe design of affiliated field and South Sea jacket platform, because this device can effectively be avoided standpipe damage and vibration, therefore, without the wearing and tearing and the loosening situation of running check rubber spacer and clamping bolt, reduce and avoided for the maintenance of submerged riser and change operation, reduced the maintenance cost in oil field.
3. the utility model device can carry out prefabricated and application in advance on land, and carry out seal tightness test, has guaranteed the quality of sealing, anticorrosion, welding inspection.
4. the utility model can design according to the concrete size of each platform jacket steel pipe, wide adaptability, promotion and application widely in the standpipe design of the South Sea, related domain deep water jacket.
