Problems solved by technology

[0003] However, to some extent, these connection methods have disadvantages such as inconvenient installation and complex structure.
Such as: claw connector, its installation reliability is high, but its structure is complicated, and the required installation tools are complicated
The degradation of the threaded connection performance of the clamp type connector will affect the performance of its connection, and it is basically not suitable for water depths greater than 1000m

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] Such as Figure 1 to Figure 7 As shown, the novel underwater pipeline mechanical connector of the present invention includes a tubular pin 1 and a tubular sleeve 2 for connecting pipelines. The shape of a hollow cylinder, the tubular sleeve 2 and the tubular pin 1 are both arranged in an axisymmetric structure. Both the tubular sleeve 2 and the tubular pin 1 are made of steel, preferably high-strength steel.

[0033] The outer surface of the tubular pin 1 is sequentially arranged as an upper cylindrical surface 14, an outer tooth segment 16, a lower unloading groove 11 and a lower positioning installation groove 4 from top to bottom, and the top of the upper cylindrical surface 14 is provided with a ring-shaped upper Flange 12, between the lower unloading groove 11 and the lower positioning installation groove 4 is provided with an axial lower connection groov...

Abstract

The invention discloses a novel underwater pipeline mechanical connector. The novel underwater pipeline mechanical connector comprises a tube-shaped pin and a tube-shaped sleeve, wherein an upper cylindrical surface, an outer tooth-shaped section, a lower unloading slot and a lower positioning mounting slot are sequentially arranged on the outer surface of the tube-shaped pin from top to bottom; an upper flange is arranged on the top of the upper cylindrical surface; a lower connecting slot is formed between the lower unloading slot and the lower positioning mounting slot; a lower oil leaking hole is formed in the upper end of the lower positioning mounting slot; an upper loading slot, an inner tooth section and a lower cylindrical surface are sequentially arranged on the inner surface of the tube-shaped sleeve from top to bottom; an upper connecting slot is formed in the top end of the upper unloading slot; a lower flange is arranged on the bottom of the lower cylindrical surface; an upper positioning mounting slot is formed in the outer surface at the upper end of the tube-shaped sleeve; an upper oil leaking hole is formed in the lower end of the upper positioning mounting slot; and an oil inlet is formed in the middle part of the tube-shaped sleeve. The novel underwater pipeline mechanical connector can meet deepwater operation needs of pipelines, does not generate influences on the marine environment, can greatly improve seabed pipeline operation efficiency, increases reliable connecting time of seabed pipelines, and reduces offshore oil development cost.

Description

technical field [0001] The invention relates to the field of offshore platforms and oil and gas pipelines, and more specifically relates to a novel underwater tubular structure or mechanical connector for pipelines. Background technique [0002] Mechanical connectors for subsea pipelines are key technologies for the design of subsea production systems. As a reliable and quick connection of underwater pipelines, it can not only reduce economic costs, but also play a good role in protecting the marine environment. At present, the conventional underwater pipeline connection methods include: welding, hydraulic connection and mechanical connection, and the mechanical connection includes bolt flange connection, claw connection, clamp connection and other methods. [0003] However, these connection methods all have disadvantages such as inconvenient installation and complicated structure to some extent. For example, the claw connector has high installation reliability, but its st...
