Tube bundle

Abstract

The invention relates to a tube bundle which comprises a tube bundle body and connector assemblies arranged at one end and / or two ends of the tube bundle body. The tube bundle body comprises a soft protective sleeve and a plurality of hoses, and the protective sleeve comprises a first end and a second end opposite to the first end; the two ends of each hose penetrate out of the first end of the protective sleeve and the second end of the protective sleeve respectively. And one end and / or two ends of each hose are / is provided with a first connecting structure which is detachably connected with the joint assembly. The pipe bundle can be used as a central bridge between a steel pipe and a deepwater pre-debugging module, pre-debugging operation at a larger water depth and diversity of deepwater pre-debugging operation can be realized, the construction cost is reduced to a great extent, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the field of offshore oil engineering, more specifically, to a tube bundle. Background technique [0002] The pre-commissioning of deepwater submarine pipelines (including pigging, pressure testing, drainage drying and inerting, etc.) is a key acceptance indicator before the new pipeline is put into production. Whether the pre-commissioning operation goes smoothly will directly affect the commissioning of oil and gas fields. Deepwater submarine pipeline pre-commissioning operations will use water, ethylene glycol, etc. for teeing, boosting, drying, etc. At present, the more advanced deep-water pre-commissioning scheme at home and abroad is to use steel pipe + hose to transport the medium to the deep-water pre-commissioning module. The problem of this scheme is that the hose has a large diameter, a large curvature radius, poor pressure bearing capacity, and joints cannot be fixed. Change and so on. These problems will greatly ...

Problems solved by technology

At present, the more advanced deep-water pre-commissioning scheme at home and abroad is to use steel pipe + hose to transport the medium to the deep-water pre-commissioning module. The problem of this scheme is that the hose has a large diameter, a large curvature radius, poor pressure bearing capacity, and joints cannot be fixed. Variation

These problems will greatly increase the construction time, increase the construction difficulty, reduce the construction efficiency, increase the number of hoisting and risks, and make the commissioning of deepwater sea pipelines unable to achieve safe, controllable and efficient operations. Therefore, it is very necessary to design a tube bundle as a The central bridge between the steel pipe and the deep-water pre-commissioning module meets the operation requirements of deep-water pre-commissioning
