Description
Technical field
The utility model relates to marine drilling platform, especially a kind of ocean engineering high-pressure slurry pipe connecting structure.
Background technology
Ocean self-elevating drilling platform and floating drilling platform high-pressure slurry pipe are between subsea wellheads and platform, mud circulation provides loop, and for drilling tool send into subsea wellheads lead, its assembly comprises seabed institute drilling well eye extension upwards, mainly contains conduction pipe, blowout preventer set, high-pressure slurry pipe connector, flexible coupling, high-pressure slurry pipe group and expansion coupling etc.Along with exploration, the continuing to increase of operating water depth, as the high-pressure slurry pipe of the key components of ocean foundation structure, be all more and more tighter to its requirements, and the bonding strength of high-pressure slurry pipe is particularly crucial.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and provide a kind of ocean engineering high-pressure slurry pipe connecting structure, design science is reasonable, structure is simple, and manufacturing process is simple, low cost of manufacture.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of ocean engineering high-pressure slurry pipe connecting structure, comprise high-pressure slurry pipe, slurry pipe flange, branch sleeve, sleeve flange and auxiliary socket, coaxial order is end to end successively for many high-pressure slurry pipes, the axial two ends of high-pressure slurry pipe are all shaped with the slurry pipe flange that cooperatively interacts thus carry out being fixedly mounted with connection, it is characterized in that: described high-pressure slurry pipe adopts the multistage low diameter-wall-rate high-pressure slurry pipe that specification is identical, the peripheral coaxial sleeve of slurry pipe flange between two adjacent high-pressure slurry pipes is equipped with a branch sleeve, axial one end internal diameter of branch sleeve and coaxial package identical with the external diameter of high-pressure slurry pipe is on the high-pressure slurry pipe starching pipe flange side, the external diameter of the coated slurry pipe flange of internal diameter of the axial other end of this branch sleeve and be coaxially shaped with sleeve flange in end, on the high-pressure slurry pipe of sleeve flange opposite side, coaxial sleeve is equipped with an auxiliary socket, this auxiliary socket is coaxially fixedly mounted with by sleeve flange and branch sleeve.
And, all seal washer is installed between described branch sleeve and high-pressure slurry pipe, between auxiliary socket and high-pressure slurry pipe and between branch sleeve and auxiliary socket.
Advantage of the present utility model and good effect are:
The utility model is by the size Control of low diameter-wall-rate high-pressure slurry pipe, and adopt high seal three-roll continuous rolling control technology to improve steel pipe sizes precision, the outer pouring interior spray quenching technology improved is adopted effectively to control material high strength and soft coupling, to meet the requirement of NACE0175 to steel pipe hardness≤22HRC, the technical level of project is in domestic pharmaceutical industry industry prostatitis, for domestically leading.
Accompanying drawing explanation
Fig. 1 is structural front view of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of ocean engineering high-pressure slurry pipe connecting structure, comprise high-pressure slurry pipe 1, slurry pipe flange 4, branch sleeve 5, sleeve flange 3 and auxiliary socket 2, coaxial order is end to end successively for many high-pressure slurry pipes, the axial two ends of high-pressure slurry pipe are all shaped with the slurry pipe flange that cooperatively interacts thus carry out being fixedly mounted with connection, and innovative point of the present utility model is:
Described high-pressure slurry pipe adopts the multistage low diameter-wall-rate high-pressure slurry pipe that specification is identical;
The peripheral coaxial sleeve of slurry pipe flange between two adjacent high-pressure slurry pipes is equipped with a branch sleeve, axial one end internal diameter of branch sleeve and coaxial package identical with the external diameter of high-pressure slurry pipe is on the high-pressure slurry pipe starching pipe flange side, the external diameter of the coated slurry pipe flange of internal diameter of the axial other end of this branch sleeve and be coaxially shaped with sleeve flange in end, on the high-pressure slurry pipe of sleeve flange opposite side, coaxial sleeve is equipped with an auxiliary socket, this auxiliary socket is coaxially fixedly mounted with by sleeve flange and branch sleeve, thus the bonding strength strengthened between adjacent high-pressure slurry pipe, protection slurry pipe flange,
In order to ensure sealing, between described branch sleeve and high-pressure slurry pipe, between auxiliary socket and high-pressure slurry pipe and between branch sleeve and auxiliary socket, all seal washer is installed.
Core technology is low diameter-wall-rate high-pressure slurry pipe size Control and hardness of steel soft matching technique.Be specially, adopt high seal three-roll continuous rolling control technology to improve steel pipe sizes precision, adopt the outer pouring interior spray quenching technology improved effectively to control material high strength and soft coupling, to meet the requirement of NACE0175 to steel pipe hardness≤22HRC.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
